摘要
针对光敏树脂固化物涂层性脆且收缩率较大的问题,合成了一种光敏树脂稀释剂———长链脂肪烃缩水甘油醚丙烯酸酯.通过控制合成条件,得到制备稀释剂的最佳合成条件,利用FTIR等方法进行了表征,并测定光敏树脂的黏度及固化物的收缩率.研究结果表明:催化剂为N,N-二甲基苄胺、用量为总质量的0 5%～1 0%、反应温度为95～105℃时为最佳合成条件;采用此稀释剂制成的光敏树脂具有良好的贮存稳定性,且固化物的柔韧性好,体积收缩率小.
In order to study the brittleness and big shrinkage of photosensitive resin's curable system, a type of active diluents for photosensitive resin--aliphatic glycidyl ether acrylic acid ester was synthesized. The optimal reaction condition was gotten by controlling the reaction condition(kind and dosage of the catalyzer, reaction temperature and etc), and the structure and properties of the final product were characterized by FTIR and by measuring viscosity and shrinkage. The results showed that N,N-dimethyl benzylamine was used as the catalyst, the ratio of the dosage of the catalyzer to the whole reactant was 0.5∶100～1∶100(w/w) and reaction temperature about was 95～105 ℃; photosensitive resin added with this type of active diluents had good storage stability and could enhance the toughening effect and reduce shrinkage of curable system.
