Study On Synthesis And Application Of UV-curing Functional Surface Coating Adhesive And Adhesive

In this paper preparation,properity and application of UV-curing surface coating adhesive and UV-curing adhesive were studied systemically.Epoxy acrylic resin (EA) and epoxy monoacrylate resin(EMA) were synthesized from biphenol A epoxy resin and acrylic acid , then a new UV-curing resin(JEA) was synthesized through the reaction of them and maleic anhydride. The effects of inhibitors,temperature , catalysts and reaction time on the every reaction were discussed systemically and the most suitable reaction condition on the every reaction was acquired. On the basis of the resin , UV-curing surface coating adhesive was made through adding photinitiator , crossinking diluents and other auxiliriarys . The infuence of various factors were discussed such as content and kind of photinitiator , diluent.The results show that UV-curing surface coating adhesive has excellent properties when content of 1-73 photoinitiator is between 2.0% and 4.0% , crossinking diluents 35-45% , resin 45-55% . The hardness,resistance of scraping,gloss , cohesion and fragility of curing coat are great improved(hardness 205, resistance of scraping 1 level and degree of gloss 158%).In this paper, photosensitive acrylate prepolymer was synthesized by the reaction of methyl methacrylate and n-butyl acrylate et al. The effects of kind of material , content of ingredient , temperature , catalysts and reaction time were discussed systemically and the most suitable reaction condition on the reaction was acquired. The the most suitable weight percentage of BA is 30-40% in total weight of MMA and BA. Polyurethane acrylate (PUA) was prepared from toluene-2,4-diisocyanate (TDI), poly(propylene glycol) (PPG) and 2-hydroxyethyl acrylate (HEA). On the basis of them , acrylate prepolymer/epoxy acrylic resin UV-curing adhesive and polyurethane acrylate/epoxy acrylic resin UV-curing adhesive were made through adding photinitiator, crossinking diluents and other auxiliriarys . The effect of content and kind of photinitiator and diluent were discussed . Photocurable technology and glass mould were used to make adhesive layer which could be used for optical and mechanical experiments.The bondability of two kinds of adhesive for glass were studied.The results show that two kinds of UV-curing adhesive have excellent properties when the content of epoxy acrylic resin respectively ranged from 15% to 25% and 25% to 35% , photoinitiator from 2.0% to 4.0% , crossinking diluents from 30% to 40%.
