Active radical group is formed after the smooth initator in system of smooth solidify colophony draws radiant energy, not saturated Shuang Jian is contained in causing a system then or contain annulus the chemical reaction between the material of oxygen radical group, form the high polymer polymer of the stereo network structure of cross-linking. It is had volatilize without inert dissolvent, solidify time is short, but the advantage that the traditional solidify technology such as microtherm solidify cannot compare, call technology of new generation green. The smooth solidify technology of high polymer material serves as energy-saving with environmental protection technology, wide already application is enclosed in coating, printing ink, electron, adhesive, presswork industry of plank, electron, imperceptible treatment and shape quickly wait for a lot of domains to achieve rapid development and great progress. Year growth rate is as high as 25% , already formed a new industry. Introduce according to expert of net of not saturated colophony, ultraviolet light (UV) solidify coating is a kind of environmental protection that 60 time develop 20 centuries energy-saving coating, photograph of coating of as dry as traditional nature or hot solidify is compared, coating of ultraviolet light solidify has clear advantage, not saturated resinite fastens smooth solidify is his important system.
Fluorine colophony and its coating are had super- constant anti-corrosive, be able to bear or endure await gender and be able to bear or endure flyblow sex. But because contain fluorine for the most part,solvent sex disperses body, must heat its to make to ability of melting point above its become film; Because contain fluorine polymer to be in the liquidity of melt condition is low, formation film burnish is inferior, adornment sex is poorer, its application was restricted on certain level. Introduce according to expert of net of not saturated colophony, did a large number of works for this people, if acrylic fluorine is acting alkyl ester polymer and blame fluorine are acting of polymer mix in all, ester of acrylic fluorine acting alkyl and the copolymerization that are not fluorine acting monomer, get together 4 fluorine ethylene is used be not fluorine resinous graft or mix modified to wait in all, and contain fluorine preparation of resinous of not saturated polyester has not appeared in the newspaper. The research to solidify of polymer ultraviolet light only confine is in the colophony that be not fluorine (if acrylic colophony, polyurethane is acrylic not colophony, acrylic epoxy resin, saturated colophony) research, the research report of smooth to containing fluorine colophony solidify is very unusual also. Because smooth solidify has energy-saving, free from contamination, operation handy wait for an advantage, and the colophony performance after solidify is superior, because this contains fluorine resinous research to smooth solidify,be conspicuous more. Gao Qingyu of chemical college of Henan university chemistry. Introduce according to expert of net of not saturated colophony, with benzene of 4 fluorine adjacent 2 formic acid replace adjacent benzene anhydride of 2 formic acid, make solvent in order to contain the active monomer of double key, synthesized contain fluorine new-styly colophony of not saturated polyester (F-UPR) , deserve to compare to its raw material, the function after synthesizing process of craft, smooth solidify and its solidify undertook study. F-UPR has better smooth solidify performance. As a result of its low surface can reach taller exterior glossiness, can use at Fu of besmear of resinous gel coat. On catenary of not saturated polyester as a result of F introduce, make the active force between molecular catenary drops, softening point thermal drop is small. Improved resinous liquidity, make treatment of resinous of not saturated polyester shapes more convenience. Introduce according to expert of net of not saturated colophony, because atom of the F in F-UPR is on benzene annulus, although resinous surface was reduced on certain level can, but the ester key apart that attends reaction to generate with suitable anhydride is further, and the density after F-UPR solidify is inferior. In alkalescent medium, f-UPR is easier hydrolysis, and hydrolysis is not reversible, alkali resistance sex is so poorer. And in acidity medium, hydrolysis is reversible, child won't leave reaction area, because its density drops,the scanty water action of F-UPR is more than suffer erodent effect. The acid-proof sex of F-UPR is good at UPR, but alkali resistance sex is differred slightly at UPR. Henan university lubricates to wait to react with epoxy resin and not saturated polyester with Li Xiaogong of functional material lab, form UP-PEP-UP to embed paragraph of copolymer, join active monomer, make modified sensitization resin, undertake ultraviolet light solidify studies. The result makes clear, the sex of alkali resistance of resinous of sensitive not saturated polyester after modified, thermal stability and exterior hardness rise greatly, solidify shrinkage is reduced apparently. Exterior hardness raises shrinkage of 4H; solidify bulk by 2H by 7% drop 0.8% , increase apparently to the adherent force of bottom material, and hot weightlessness rate was reduced 6.8% . Expanded it is in the utility of a lot of respects. Introduce according to expert of net of not saturated colophony, jie Yijun of Heibei industry university and Li Zunbang put forward a kind to be embedded by not saturated polyester and epoxy resin paragraph in all condensation polymerization, synthesize a kind of new-style photosensitive to get together beforehand the method of content. This photosensitive gets together beforehand content uses two footwork synthesis. The pace is synthesized first have quality of certain and opposite element and the not saturated polyester that carry carboxyl group, the 2nd pace makes this not saturated polyester and epoxy resin react, generate embed paragraph in all condensation polymerization content. This photosensitive gets together beforehand the opposite element quality of content through adjusting the opposite element quality of not saturated polyester is controlled. Get together beforehand to complex photosensitive content did photosensitive to coating makes up research and undertake function token to film. The opposite element quality that fat embeds paragraph of copolymer but by adjust Maerbi controls the excessive of not saturated acid. Excessive Maerbi is bigger, opposite element quality is greater, solidify rate is rapidder also. Introduce according to expert of net of not saturated colophony, photosensitive of this method complex gets together beforehand the exterior hardness of content solidify film, withy model, the function such as adherent force, hear resistance all acrylic acid of excel annulus oxygen is not ester, saturated the commonly used photosensitive such as polyester colophony gets together beforehand content breed. Although photosensitive sex of the system basically depends on photosensitive resinous function, but also concern with other constituent. Through adjusting the breed of active thinner and dosage can change smooth solidify rate inside certain limits, the hardness of solidify film, flexibility reachs adherent power.
