酚醛树脂丙烯酸酯季铵盐感光性能的研究

通过凝胶生成率的测定，研究了紫外光引发剂：安息香（NB）、安息香乙醚（BE）、2，2－二乙氧基苯乙酮（DEAP）、二苯甲酮（BP）、2－丙基硫杂蒽酮（ITX）；交联型稀释性单体：二乙二醇二丙烯酸酯（DEDA）三乙二醇二丙烯酸酯（TEDA）、二乙二醇二甲基丙烯酸酯（DEDMA）、三乙二醇二甲基丙烯酸酯（TEDMA）、三羟甲基丙烷三丙烯酸酯（TMPTA）、三羟甲基丙烷三甲基丙烯酸酯（TMPTMA）；胺增效剂：乙基－4（二甲基氨基）苯甲酸酯（DEAB）等对水溶性酚醛树脂丙烯酸酯季铵盐（PreP)感光性能的影响。结果表明，ITX的光引发效率最高；交联型黧性单体中活性基团越多，反应活性越高，分子量越大，反应活性越差；二乙醇类与PreP的相容性比三羟甲基烃类的要好；胺增效剂能提高ITX的引发效率；PreP/DEDA=1/0.6(g/g),ITX为0.025mmol/g,DEAB为感光组分的2％，曝光60s，凝胶生成率可达到67.6%，延长曝光时间凝胶生成率增加。

PHOTOCROSSLINKING BEHAVIOR OF BOTH ACRYLATE AND QUATERNARY AMMONIUM SALT GROUPSCONTAINING PHENOLIC RESIN

The influences of photoinitiators, crosslinking diluent monomers and amine accelerator on photosensitive properties both acrylate and quanternary ammonium salt groups containing phenolic resin were studied. The results show that within the five photoinitiators ITX is the most effective in initiation. Among the crosslinking diluent monomers the larger the number of double bond groups in the monomer or the smaller the molecular weight of the monomer, the higher is the reactively. Diethylene glocol type monomers are more compatible with epoxy phenolic resin containing acryloyl groups and quaternary ammonium groups than the trimethylolpropane type monomers. Amine accelerator can enhance the photoinitiator efficiency.
