Cathodic electrophoretic coating acrylic resin Synthesis and Application
No change No change No change No change No change 1o60.20.190.260.3430252530 No change No change No change generally good good film appearance light yellow , transparent, flat , smooth 2.5 feed ratio on the film properties According to different properties and effects of different monomers in the polymerization were chosen M / VIA, BA, GMA monomers , by polymerization in different proportions , corresponding to test the performance of its corresponding film showed an increase Adjust the hardness monomer (MMA) ratio , film hardness ; increase the amount of BA monomer tough adjustment , film gloss, improved impact resistance ,[link widoczny dla zalogowanych], but the hardness decreased. Therefore, it can be adjusted according to actual requirements of the ratio of MMA and BA . 3 Conclusions (1) experiment and analysis shows that , GMMMA / BA copolymers process is stable , easy to control. (2 ) epoxy group containing terpolymer amination is pressed the ring oxygen reaction , the generated secondary alcohols tertiary amine compounds. (3 ) Department of epoxy ester acrylic cathodic electrophoretic coating materials can be used as the main resin used, excellent film properties . (4 ) through the film properties can be adjusted the content of epoxy ester .
