摘要/Abstract

摘要： 分析了环状对苯二甲酸丁二醇酯(CBT)-CBT100和CBT160两种树脂的反应特性,研究了三种锡类催化剂对CBT100树脂低粘度适用期和高温反应时间的影响,并对比了采用树脂粉末熔融浸渍成型和高温真空辅助灌注成型(VARTM)方法制备的玻璃纤维增强聚环状对苯二甲酸丁二醇酯(PCBT)复合材料的力学性能。研究结果表明,CBT160树脂高温反应速度较快,适合树脂粉末熔融浸渍相类似的成型工艺。CBT100树脂通过外加一定量的单丁基三异辛酸锡或二丁基二月桂酸锡催化剂,可以使其具有合适的适用期和反应聚合时间,适宜用于VARTM过程。含单丁基三异辛酸锡的CBT100树脂通过高温VARTM方法制备的玻纤增强PCBT复合材料的综合力学性能较好,略高于采用CBT160树脂用树脂粉末熔融浸渍成型方法制备的复合材料的力学性能。

Abstract: The reaction characteristics of cyclic butylene terephthalate (CBT) resin, CBT100 and CBT160 resin, were analyzed. The influence of three kinds of tin catalysts on CBT100 resin low viscosity pot life and polymerization time at high temperature was studied. Glass fiber reinforced poly(cyclic butylene terephthalate) (PCBT) composite materials were prepared by resin powder melting and impregnation molding process and high temperature vacuum assisted resin transfer molding (VARTM) process respectively and their mechanical properties were compared. The research result showed that CBT160 resin reacted rapidly at high temperature and it was suitable for molding processes similar to resin powder melting and impregnation molding process. CBT100 resin could obtain proper pot life and polymerization time by adding certain amount butyl tin tris-2-ethyl hexanoate or butyltintris(2-ethylhexoate) catalyst, enabling it suitable for high temperature VARTM process. Glass fiber reinforced PCBT composites prepared by high temperature VARTM process using CBT100 resin and butyl tin tris-2-ethyl hexanoate catalyst has excellent mechanical properties, which was slightly better than that made by powder melting and impregnation molding process using CBT160 resin.

Key words: cyclic butylene terephthalate, thermoplastic composites, resin powder melting and impregnation molding, high temperature vacuum assisted resin transfer molding, mechanical properties
