Adhesive is expect in order to stick give priority to an agent, cooperate the auxiliary such as all sorts of solidify agents, plasticizer and filling to make up, its and our daily life be closely bound up, the interface with different even qualitative capable person undertakes the interface that can pledge akin material be stuck effectively receive, be used at sticking to take over handicraft, furniture to repair normally, glass is sealed, pack etc, outside using a field except the tradition, the development that waits for burgeoning application domain in electric equipment of wind report, electron, aerospace has adhesive wide perspective. Current, below the guiding of relevant policy, adhesive product changes development to high-powered, environmental protection gradually, the new-style application range of adhesive is more wide.
According to different molecular structure, adhesive can be divided again wait for adhesive of organic silicon adhesive, polyurethane adhesive, hot frit, epoxy resin adhesive, among them, epoxy resin adhesive can be received to undertaking sticking between metal and most metalloid material, use extensively at building, car, electron, electric equipment and respect of daily household articles for use. For example, in electronic electric equipment in enclosing a domain, because epoxy resin fill seals glue to have shrinkage function of small, heat-resisting and dielectric protecties beautiful, sealing is good wait for a characteristic, can serve as enclose material goodly, rising those who enclose is convenient degree lead with the success while, also can promote those who enclose is fast degree. Because fill of this epoxy resin seals glue,be electronic electric equipment enclose the adhesive product with domain most wide application.
Epoxy resin itself is a linear structure is thermoplastic colophony, performance is very steady, add solidify agent only, make it by reticulate of line structure cross-linking or stereo structure, ability has admirable performance characteristics, and the function of solidify child depends on greatly solidify agent, accordingly, solidify agent is the essential component in epoxy resin use process. The sort of agent of epoxy resin solidify divides a lot of kinds, the use setting collocation that wants a basis to differ adds up to comfortable solidify agent, ability play gives the performance with epoxy resin first-rate system.
Solidify agent basically divides epoxy resin to be in to show model with conceal model two kinds, show in model solidify agent is normally common use solidify agent, general component is amine, acid anhydride kind, phenolic aldehyde kind, alkyd, get together sulfur is mellow kind etc, or of agent of this kind of solidify passes dozen of open loop the annulus of oxygen radical undertakes addition polymerization reacts, itself participates in three-dimensional and reticulate structure in, or makes with shade cation means annulus oxygen base open loop addition is aggregate, itself does not participate in reticulate structure; Conceal solidify agent is to point to after mixing with epoxy resin, keep stable below certain condition, but expose when its fall in special condition (wait like smooth, hot, damp) when, begin to produce solidify reaction.
At present to get used to colophony modified demand, development has fast solidify, microtherm solidify, add pliable but strong, flame retardant the agent of functional sex solidify that waits for superior performance, and the central point that agent of low poison, avirulent solidify and the solidify agent that get used to special environment made the attention on the market. Get together sulfur alcohol is among them agent of solidify of sex of a kind of function, in proper accelerant (the amine that be like father's younger brother) the speed promotion that can react solidify below action comes of yuan of many amine solidify agent multiple, because this gets together,sulfur alcohol is had in certain and specific domain cannot replace a gender. For example it can be in - 10 ℃ undertake fast solidify below the microtherm environment of or so, because this suits winter,the construction outdoor uses adhesive; Its hardness develops fast, low poison / fizzle out avirulently, not easily the character that change also makes its are in “5 minute adhesive of ” disappear charge and wide application received in repairing glue quickly; And felt force strong, tenacity is good the advantage that waits for mechanical function also decided it the significant position in agent of epoxy resin solidify. In addition, get together because agent of sulfur mellow solidify contains sulfur flexible catenary paragraph have high refractive index, there also is greater applied value in transparent colophony and respect of the colophony that add pliable but strong.
Because get together,agent of sulfur mellow solidify belongs to agent of solidify of epoxy resin of domain of special high end to use a field, and the technology is broken through harder, need and downstream and actual application are united in wedlock cheek by jowl, because of layout of this whole world the business of this product is not much, abroad is current and main with the United States the SC chemistry of Lu Nuo of cloth of Dong Li of Hengsiman, Japan, Germany, Japan developed country that is a delegate is long-term forestall this market, and the development research of domestic production company to this domain is less, only a few enterprise that with Shandong beneficial Feng Xincai expects Inc. is a delegate realized a quantity to produce, partial product already came true completely in domain of certain high end homebred change replace.
Beneficial abundant gets together sulfur is mellow 309 it is low temperature of an epoxy resin fast solidify agent, the exterior is colorless flaxen perhaps transparent liquid, normal temperature (25 ℃ ) next viscosity limits are 12000~14000 MPa·s, ≥12 of Qiu radical content, chroma ≤20, can use at be bored with of adhesive of glue of 5 Minutes AB, electron, ferrule oxygen child, the applied domain such as glue of marvellous cut of glue of electronic heat conduction, preservative coating, silicon. Among them, get together 309 generated silicon have sulfur alcohol after solidify of marvellous cut adhesive higher bonding strength and flexibility, can reduce what silicon club arises in cut process to drop piece, the blemish such as edge collapse and crackle, raised the fine rate of itself of silicon marvellous cut thereby, after silicon marvellous cut is finished, stick the silicon chip that has adhesive to immerse to be able to be broken away from easily quickly in Wen Shuizhong. According to bureau of national energy resources newest data shows, installation amount of accumulative total of our country smooth hot season had achieved 392.61GW 2022, add installation amount newly to achieve 87.41GW, achieve the history again new tall, and rank the world 10 years continuously the first. What contend for carbon of the implementation before 2030 to amount to peak and carbon of the implementation before 2060 to counteract according to our country force is important declare, the clean the sources of energy such as industry of smooth hot season is in exhibition period of bitter fleabane break out, refine the requirement of cut technology to also will promote ceaselessly to essence of life, will naturally bring the rapid growth of demand of glue of marvellous to silicon cut.
In addition, get together sulfur is mellow 309 also can use at generating to enclose adhesive, enclose a be process of production of electronic electric equipment important working procedure, use not dismountable means more, discard as useless because of what the failure that this encloses means a product, the production to the enterprise will produce adverse effect. In electronic component in enclosing working procedure, enclose adhesive to be able to protect action to arriving since electronic component, can prevent the element such as moisture, dust and harmful gas to be opposite already electronic parts or report board erode, slow down or quits outside force, can oscillatory brought loss, increase electronic parts stability thereby. Live in those who wait for product requirement of electronic electric equipment to grow continuously as smartphone, intelligence, the augment that dimensions of market of Chinese electron product stabilizes continuously, will drive product of electronic electric equipment to rise of demand steadily to adhesive.
Get together the applied field with extensive agent of sulfur mellow solidify
In addition, beneficial abundant still is rolled out get together sulfur mellow 405—— 4 (3- Qiu base third is acerbity) Ji Wu 4 mellow ester, its are a kind of fast solidify gets together agent of sulfur mellow solidify, applicable at the tooth the high-end adhesive domain such as optical glue of glue of electron of film of feature of abnormal adhesive, quanta, 3C, UV. Get together nevertheless the odor problem of sulfur alcohol is perplexing downstream client all the time, beneficial abundant already rolled out dull to get together now sulfur is mellow 405 products, extended the applied domain of the product further, satisfied a client more the demand of diversity.
Inc. of beneficial abundant new material held water 2011, be progress of chain of industry of data of optics of a focusing only enterprise of ” of small giant of new “ of spy of essence of life. Come for years, beneficial abundant new material insists to develop with industry of drive of science and technology from beginning to end, for appliance of clairvoyant and healthy modes of life and relation to their environment (appliance) the industry provides the optical data that is core with containing sulfur, achieved distribution of product line of high additional cost, terminal is covered inspect the country such as medicine of smooth, electron, biology, new energy resources to support a domain mainly, the product is sold as far as to the United States, Italy, Holand, Japan, Korea, medium inferior, more than 20 countries such as southeast Asia and area.
