Vinyl colophony, also call vinyl ester colophony, it is the colophony of hot solid sex that passes what chemistry of open loop addition reacts and make by epoxy resin and methylic acrylic acid. Because vinyl colophony is had,have good mechanical performance, tenacity, hear resistance and cohere sex, be able to bear or endure exceedingly goodly chemical sex and the character of facilitating solidify, its apply a domain to expanding ceaselessly. So, do vinyl colophony and epoxy resin have after all why to distinguish? Virtuous market network is small today make up, to everybody all-around contrast two kinds of colophony, let you clear up defect of the sort of vinyl colophony and epoxy resin, actor, application and craft. One, vinyl resinous sort and actor defect first, will know vinyl colophony first. Vinyl of oxygen of annulus of vinyl colophony full name ester colophony (Epoxy Vinyl Ester Resin, english abbreviate VER) , also abbreviation is vinyl ester colophony, ethylene ester colophony, it is colophony of sex of a kind of hot solid. Vinyl colophony holds concurrently provided epoxy resin (Epoxy Resin) and colophony of not saturated polyester (the advantage of Unsaturate Polyester Rein) , namely high strenth, be able to bear or endure chemistry is corroded and good technical properties; And tall without the marked weakness —— of epoxy resin viscosity, not easy treatment and high cost. Vinyl colophony by epoxy resin (be like double phenolic A or varnish of phenolic aldehyde of oxygen of epoxy resin of 4 bromic double phenolic A, annulus and 2 annulus oxidation get together oxidation propylene) and not saturated a yuan of carboxylic acid (wait like acrylic, methylic acrylic acid) reaction gets. As a result of colophony complex craft and method different, vinyl resinous structure, function and application also have a difference. Vinyl colophony (the type of VER) includes: A of ① double phenol is general-purpose A of VER double phenol is general-purpose VER is pass compound of reaction of open loop addition by methylic acrylic acid and aether of glycerine of shrink of double phenolic A2 epoxy resin dissolve the solution at styrene dissolvent. ② bromine changes vinyl of oxygen of annulus of double phenolic A ester colophony bromine changes vinyl of oxygen of annulus of double phenolic A ester colophony (flame retardant model annulus oxygen vinyl ester colophony) use bromine to change synthesis of open loop of epoxy resin of double phenolic A commonly. Because bromine is contained in colophony, because this is flame retardant model ester colophony has annulus oxygen vinyl already with general-purpose vinyl of oxygen of annulus of double phenolic A ester colophony is able to bear or endure identically chemical sex, gift again at the same time colophony from extinguish sex. Epoxy resin of ester colophony phenolic aldehyde introduces oxygen of annulus of ③ phenolic aldehyde vinyl in framework of ethylene ester resinous, ester colophony calls vinyl of complex annulus oxygen vinyl of NOVOLAC annulus oxygen commonly ester colophony, colophony has taller thermal stability. The vinyl of oxygen of phenolic aldehyde annulus after solidify ester colophony, cross-linking density tall, hear resistance is good, can prolong service life and have admirable corrosion resistance, special chloric to containing solution or organic dissolvent corrosion resistance are good. Vinyl of oxygen of annulus of phenolic aldehyde of density of ④ tall cross-linking ester colophony to suit high temperature resistant the need of strength condition, more manufacturer to vinyl of oxygen of phenolic aldehyde annulus ester colophony undertook modified, improved resinous cross-linking density and heat-resisting performance, have admirable acid-proof, be able to bear or endure solvent is caustic and fight oxidation function, apply to all sorts of high temperature strong corrode a circumstance, if absorb the tower, high temperature chimney that contains all sorts of waste gas,wait. Colophony of ⑤ photosensitive vinyl because the not saturated Shuang Jian in vinyl colophony resinous is carried in molecular catenary, active is taller, deserve to be designed with the element at the same time, if use the epoxy resin that oxygen of tall be surrounded by mountains is worth, use acrylic acid to replace methylic propylene base the vinyl colophony after acerbity synthesis, join smooth initator (aether of marriage of the Kun that be like benzene, benzene idol) , in order to draws ultraviolet energy, transfer colophony system, and make vinyl colophony undertakes aggregate solidify. This kind of colophony can be used at pressworking, photosensitive printing ink, use as on painter course of study photosensitive coating, the light that makes PCB go up is used to deliver the film that fight corrode in radio industry. ⑥ is flexible vinyl ester colophony to get used to the need of all sorts of anticorrosion engineering construction, appeared flexible vinyl ester colophony, flexible vinyl ester colophony is had very tall to steel and concrete surface stick receive a gender, with traditional annulus oxygen vinyl ester colophony photograph is compared, its are outspread rate is higher, stick receive strength greatly rise, fight strong intensity to raise nearly 4 times, the intensity between the layer rises 20% , have distinctive wearability. Besides above introductory breed, still have vinyl of oxygen of PU modified annulus ester colophony, SMC/ BMC uses annulus oxygen vinyl ester colophony waits vinyl of oxygen of annulus of solidify of ester colophony, radiate a moment. In foreign course development of 50 years and application are developed, 20 old exploration are passed in home, the colophony of sex of high-powered hot firm that vinyl ester colophony has developed special function, in composite material, anticorrosion, coating, glue a lot of domains such as sticky agent had received wide application. 2, the sort of epoxy resin and actor weakness are similar, we introduce epoxy resin simply first. Epoxy resin (Epoxy Resin) it is generally refer to contain two or oxygen of two above annulus base, with adipose a group of things with common features, fat annulus a group of things with common features or the organic compound such as scent a group of things with common features is framework and can carry ring the high polymer that reaction of oxygen radical group forms useful hot solidify production is low get together body (Oligomer) . It is zero hour when N of degree of polymerization, the oxidation is annulus that say closes matter, abbreviation annulus oxide (Epoxide) . The sort of epoxy resin is very much, and have new breed ceaselessly appear. The classified method of epoxy resin is very much also. Press its normally the combinative means substantially of oxygen radical divides chemical structure and annulus it is 5 kinds big: (Aether of 1) shrink glycerine kind, (Ester of 2) shrink glycerine kind, (Amine of 3) shrink glycerine, (4) is adipose compound of oxygen of a group of things with common features annulus, (5) fat annulus compound of oxygen of a group of things with common features annulus. The type that common epoxy resin introduces in detail below reachs a characteristic. A of double phenol of of A of ① double phenol epoxy resin (namely 2 phenol base propane) model epoxy resin namely 2 phenol base aether of propane shrink glycerine. In its raw material in epoxy resin easy, cost is low, crop is consequently big. Its occupy the 90 % of epoxy resin total output about in our country, making an appointment with the 80 % of 75 % ~ that hold epoxy resin total output. Because its use is extensive, reason is called general-purpose epoxy resin. The molecular structure of double phenolic A epoxy resin decided its function has hot solid sex, can with a variety of solidify agents, activator and additive form the condensate with a variety of superior performance, can satisfy all sorts of use requirement almost. Main drawback is: Hear resistance and tenacity are not tall, be able to bear or endure sex of damp and hot and be able to bear or endure the difference that await a gender. of F of ② double phenol epoxy resin this is to reduce a kind of when the viscosity of itself of double phenolic A epoxy resin has same function and development goes new-style epoxy resin. It is to use double phenolic F normally (2 phenol base methane) the F of liquid state double phenol that as chloric as annulus oxygen propane reacts below NaOH action and gets epoxy resin. The characteristic of double phenolic F epoxy resin is viscosity small, be less than the 1/3 of viscosity of double phenolic A epoxy resin, good to fibrous macerate sex. The function of its condensate and double phenolic A epoxy resin is almost identical, but hear resistance is a bit low and corrosion resistance actors or actress a bit. Double phenolic F epoxy resin can use liquid state at having solvent coating, adhesive, casting plastic, glass reinforced plastics and carbon fiber composite material. Aether of glycerine of ③ much phenol shrink aether of glycerine of much phenol of epoxy resin shrink epoxy resin is a kind of many luscious round epoxy resin. The annulus oxygen that there are two aboves in its element base, the cross-linking density of condensate is accordingly big, have admirable hear resistance, intensity, model quantity, insulating property, be able to bear or endure ability in swimming and corrosion resistance. ④ is adipose a group of things with common features shrink glycerine aether epoxy resin is adipose a group of things with common features shrink glycerine aether epoxy resin is by binary or multivariate chloric propane of alcohol and annulus oxygen is changed in aether of the open loop below activator action, generate chloric alcohol intermediate child, again with alkaline reaction, take off HCl closed circuit, form shrink glycerine aether. Adipose a group of things with common features shrink glycerine aether epoxy resin is by 2 or oxygen of 2 above annulus base be linked together directly with adipose catenary and become. The cricoid structure such as benzene annulus, fat annulus and heterocycle is done not have in molecular structure. Viscosity of great majority of this kind of colophony is very small, most breed is on Ou Shuirong sex, great majority is long chain element, because this is full of flexibility. But its hear resistance is poorer. Ester of ⑤ shrink glycerine kind amine of glycerine of shrink of epoxy resin epoxy resin and 2 phenol base colophony of propane annulus oxidation is compared, have viscosity low, use craft sex is good; Agglutinate power is higher than general epoxy resin, it is good that solidify material resources learns function; Insulating property weatherability is good, good, and have be able to bear or endure goodly ultralow temperature sex, below ultralow temperature condition, still have higher than other type epoxy resin bonding strength. Have better exterior glossiness, pervious to light gender, weatherability is good. ⑥ fat annulus a group of things with common features annulus of fat of epoxy resin a group of things with common features epoxy resin is small element compound, viscosity sex of small, craft is good. Can use as active thinner. Annulus oxygen equivalent is small, cross-linking density is big, plus the rigid fat link with have thermal stability nice, hear resistance is accordingly tall, but more fragile, tenacity is poor. Solidify systole is small, tensile strength is high. Because plasma of Cl, Na is not contained in synthetic process, electric performance is so good, especially function of high temperature report and be able to bear or endure electric arc sex is good. Do not contain benzene annulus, be able to bear or endure consequently ultraviolet ray and be able to bear or endure it is good to await a gender. 3, the performance of vinyl colophony and epoxy resin is comparative 1, the good character that colophony of vinyl of ① of characteristic of vinyl colophony function took epoxy resin, solidify sex and shape sexual respect is more outstanding, can deliquescent fasten monomer at styrene and acrylic acid. ② colophony viscosity is low, but normal temperature solidify, the operation is convenient, construction does not accept seasonal restriction. ③ has admirable corrosion resistance can, alkali resistance sex and epoxy resin are similar, acid-proof sex and fight oxidisability and likeness of colophony of double phenolic not saturated polyester. The vinyl colophony with cross-linking high density has good solvent patience. 2, mechanical performance of ① of characteristic of epoxy resin function is high. Epoxy resin has very powerful cohesive force, molecular structure is compact, so colophony of its phenolic aldehyde of mechanical function prep above is mixed not saturated polyester general-purpose solid sex colophony. ② adherent force is powerful. Active huge is contained in system of epoxy resin solidify annulus oxygen base, the polar group such as hydroxyl and ether key, amine key, ester key, gift annulus oxygen condensate wait for polarity base material to cermet, glass, concrete, lumber with good adherent strength. ③ solidify shrinkage is small. It is 1%-2% commonly. It is one of assortment with small shrinkage of the solidify in colophony of hot solid sex. ④ craft sex is good. Epoxy resin basically does not produce small element volatile when solidify, low pressure shapes or can contact so pressure shape. Can cooperate to make with all sorts of solidify agents wait for environmental protection coating without solvent, tall solid, coating and coating of ability in swimming. ⑤ fights chemical function admirable. Annulus oxygen condensate has excellent chemical stability. The function excel that a variety of medium such as its alkali resistance, acerbity, salt corrode is not saturated the heat such as polyester colophony, phenolic aldehyde colophony originallies sexual colophony. 4, the application of vinyl colophony and epoxy resin is comparative 1, domain of vinyl colophony application differentiates by the industry, main component is vinyl colophony market 3 kinds: Composite material, paint, coating and other. Vinyl colophony base composite material applies extensively at conduit, storage tank, building, carry wait for an industry. The corrosion resistance with vinyl admirable colophony and superior physico-chemical performance, make its become the select material of project of FRP of anticorrosion of many chemical industry to expect. Be like canister of chamfer of glass reinforced plastics, conduit, tower implement and anti-corrosive grille; Anticorrosion project, be like tall anti-corrosive goods of FRP of ground level ground, high strenth; Weigh puddle of coating of anticorrosive glass scale, scale; Power plant to decoke is anticorrosive, high temperature resistant, be able to bear or endure strong acid alkali; Chemical workshop workbench is acid-proof alkali resistance is high temperature resistant anticorrosive wait. In recent years, as the innovation that special function changes vinyl ester resinous and development, a few new application received in downstream and numerous domain: 1) puddle of scale of glass of vinyl ester colophony received very good promotion and application in domain of to decoke of flue gas of blame heat and power plant, especially glass reinforced plastics / daub is compound liner received more and more promotion and application in domain of liner of chamfer of chemical industry pool; 2) thick oar vinyl ester colophony kind coating, include scale coating and blame scale painting, had received a large number of promotion and application; 300μm film has begun to start on market of large coating of vinyl ester colophony, present the trend that high speed grows; 3) the vinyl ester colophony of tall oxygen index and give attention to two or morethings of low smoke density is in be able to bear or endure corrode is flame retardant the FRP domain of give attention to two or morethings got popularize and applied; 4) the vinyl ester colophony of 0 systole, tall tenacity is in the domain such as pole of FRP helmet, fishing received extensive promotion and application; 5) the domain of FRP structural member in a few special requirements got the vinyl ester resin of give attention to two or morethings of high strenth, Gao Yanshen rate extensive promotion and application; 6) be able to bear or endure superhigh temperature (gas phase 200 ℃ above) , be able to bear or endure ultralow temperature (40 ℃ of ―) special function changed vinyl ester colophony to get popularize and applied; 7) vinyl ester colophony is in special and electric material (if engine uses kryptol of insulation FRP, semiconductor to wait) the domain received a few promotion and application; 2, the physical machinery with good epoxy resin of domain of epoxy resin application and dielectric protecties, with all sorts of material stick receive performance, and the flexibility that its use technology is other heat originallies plastic place does not have the sex. Accordingly it can make material of makings of coating, composite material, mould, adhesive, mould pressing and inject expect into profile, wide application receives in each domains of national economy. ① coating epoxy resin holds larger proportion in the application in coating, it can make each have characteristic, use the breed of each different. Its general character: 1) is able to bear or endure chemical sex is admirable, be able to bear or endure especially alkalescent; 2) paint film adds exert oneself strong, be opposite especially metal; 3) has better hear resistance and insulating property; Colour retention of 4) paint film is better. Epoxy resin coating basically uses as priming paint of anticorrosion lacquer, metal, insulating varnish, but the coating that epoxy resin makes annulus a group of things with common features can use heterocycle and fat at outdoors. Adhesive of oxygen of ② adhesive annulus is the important breed of structural adhesive. Epoxy resin besides plastic to the blame polarity such as polyolefin caking property bad besides, be like aluminous, steel, iron, copper to all sorts of metal stuff; Metalloid material is like glass, lumber, concrete to wait; And hot solid sex is plastic wait to have like not phenolic aldehyde, amino, saturated polyester stick admirably receive performance, say because of what this has all-purpose glue. Material of ③ electron electric equipment because intensity of tall, structure mixes the insulation property of epoxy resin greatly sealed performance is good wait for a lot of distinct advantages, already pressed electric equipment, electric machinery and electron in on any account yuan the insulation of parts of an apparatus reachs a mount to get applied extensively, development is very rapid. Basically use at: 1) insulation of electric equipment, electric machinery is enclosed pouring; 2) the fill that is used at the parts of an apparatus of electronic component and circuitry seals insulation. 3) makings of moulding of oxygen of electronic class ring is used at semiconductor yuan the model of parts of an apparatus is sealed; 4) in addition, adhesive of coating of insulation of oxygen of makings of compression moulding of annulus oxygen layer, annulus, insulation, report adhesive also has a large number of application. ④ project is plastic with project of oxygen of annulus of composite material plastic and main the annulus oxygen moulding that includes to be used at high pressure to shape expects and annulus oxygen lamination is plastic, and annulus oxygen expanded plastics. Annulus oxygen project is plastic the annulus oxygen that also can be being regarded is a kind of broad sense composite material. A kind of composite material is the hi-tech domain such as chemical industry and aviation, spaceflight, war industry important construction material mixes annulus oxygen functional material. ⑤ earth building materials expects epoxy resin is constructing a field, basically use as mortar of oxygen of anticorrosive level ground, annulus and concrete products, advanced road surface and airport runway, fast adhesive of the material of form a vesicle that repairs foundation of foundation of material, consolidate, building and coating.
