摘 要:在“双碳”发展战略目标的背景下,为探索绿色环保型生物基环氧树脂在电工设备上的应用前景,本文以可再生资源松香为原料,制备了一种生物基树脂——马来海松基环氧树脂(MPAER)。以甲基六氢邻苯二甲酸酐(MHHPA)为固化剂,对MPAER/MHHPA体系的固化特性、热性能、力学性能和电气性能进行了系统研究,并和商用双酚A二缩水甘油醚(DGEBA)组成的DGEBA/MHHPA体系进行对比。结果表明:MPAER/MHHPA和DGEBA/MHHPA体系的固化反应活性相当,MPAER/MHHPA体系的玻璃化转变温度为112.8℃,其力学性能和电气性能均稍弱于DGEBA/MHHPA体系,其中MPAER/MHHPA体系的电气强度比DGEBA/MHHPA体系低9.4%。但MPAER/MHHPA体系的综合性能仍较好,可以通过对MPAER进行结构优化或者与其他类型的环氧树脂共混来进一步提高其性能。Under the background of“carbon peaking and carbon neutrality”development strategy goal,in order to explore the application prospects of green and environment friendly bio-based epoxy resins in electrical equipment,a bio-based resin of maleopimaric-based epoxy resin(MPAER)was prepared using a renewable resource of rosin as raw material.Taking methylhexahydrophthalic anhydride(MHHPA)as the curing agent,we systematically studied the curing characteristics,as well as the thermal,mechanical,and electrical properties of the MPAER/MHHPA system,and the MPAER/MHHPA system was compared with the DGEBA/MHHPA system composed of commercial diglycidyl ether of bisphenol A(DGEBA).The results show that the MPAER/MHHPA system and DGEBA/MHHPA system have equivalent curing reaction activity.The glass transition temperature of the MPAER/MHHPA system is 112.8℃,its mechanical and electrical properties are slightly weaker than those of the DGEBA/MHHPA system,and its electric strength is 9.4%lower than that of the DGEBA/MHHPA system.However,the comprehensive performance of the MPAER/MHHPA system is still good,and its performance can be further improved by optimizing the structure of MPAER or blending with other types of epoxy resins.
