将氢化环氧树脂(AL-3040)和自制的含氟环氧树脂按不同的物质的量比共混,以聚丙二醇二缩水甘油醚(XY-207)为环氧稀释剂、1,8-薄荷烷二胺(MDA)为固化剂,完全固化之后制备出一种新型的含氟形状记忆环氧树脂体系,并表征了其分子结构、含氟环氧树脂含量对固化体系储能模量和形状记忆性能的影响,测试了体系表面和冲击断面含氟量以及冲击力学性能。研究结果表明:增大体系含氟环氧树脂含量时,固化体系的交联度增大;固化体系的储能模量随含氟环氧树脂含量的增加而增大;该形状记忆含氟环氧树脂体系具有良好的形状记忆性能,形变完全的时间随体系含氟环氧树脂含量的增加而缩短。
Abstract：Using polypropylene glycol diglycidyl ether(XY-207)as the diluent of epoxy resin and 1,8-menthane diamine(MDA) as the curing agent,a novel fluorine-containing shape memory epoxy resin system was prepared by blending the hydrogenated epoxy resin(AL-3040)with self-made fluorine-containing epoxy resin according to different mass fraction ratios. The effects of the molecular structure and the content of fluorine-containing epoxy resin on the storage modulus and shape memory properties of curing system were characterized. The fluorine content and impact mechanical properties of the system surface and impact section were also tested. The research results showed that when the content of fluorine-containing epoxy resin increased,the crosslinking degree of curing system increased. The storage modulus of curing system increased with the increase of the content of fluorine-containing epoxy resin. The fluorine-containing shape memory epoxy resin system had good shape memory property,and the time of complete deformation was shortened with the increase of the content of fluorine-containing epoxy resin.
