摘要：以回收的三羟甲基丙烷前馏物和环氧氯丙烷为原料、三氟化硼乙醚络合物为催化剂合成了缩水甘油醚（TMPS）,并用作环氧稀释剂。采用红外光谱,力学性能测试,动态热机械性能及热重分析等对比研究了TMPS及622环氧稀释剂对环氧固化体系性能的影响。结果表明：E51/TMPS固化体系相对于E51/622体系力学强度更高,刚性强,玻璃化转变温度更高。但由于E51/TMPS固化体系存在未参加固化反应的小分子,使得固化体系不完全相容,因而热分解温度略低于E51/622固化体系。
The gycidyl ether（TMPS） was synthesized using recycled trimethylolpropane pre-distillate and epichlorohydrin as raw materials and trifluorideboron ether complex as catalyst,and the TMPS was used as epoxy diluent. The effects of TMPS and 622 epoxy diluents on the properties of epoxy cured system were comparatively studied by infrared spectroscopy,mechanical property testing,dynamic thermomechanical analysis and thermogravimetric analysis. The results showed that E51/TMPS curing system had higher mechanical strength,higher rigidity and higher glass transition temperature than those of E51/622 system. However,due to the presence of small molecules that did not participate in the curing reaction,the cured system was not completely compatible and thermal decomposition temperature of E51/TMPS cured system was slightly lower than that of the E51/622 system.
