双马来酰亚胺树脂环氧树脂复合材料的制备方法
摘要：
本发明涉及高分子材料领域，具体地说是一种双马来酰亚胺树脂环氧树脂复合材料的制备方法。包括下述步骤：按重量计，将50～100份双马来酰亚胺树脂、20～100份烯丙基类化合物、1～30份增韧剂，在50～200℃下搅拌，熔解分散均匀后，降温到70～150℃，加入0.1～10份抗氧剂、0.1～20份紫外光吸收剂，熔解分散均匀后，降温到70～150℃，加入1～50份环氧树脂、0.1～10份偶联剂、0.1～10份触变剂，分散均匀后，得到树脂组合物，将树脂组合物进行涂膜工序与纤维复合工序，固化后得到双马来酰亚胺树脂环氧树脂复合材料。
摘要（英）：

The invention relates to the field of high polymer materials, in particular to a preparation method of a bismaleimide resin and epoxy resin composite material. The preparation method comprises the following steps: stirring 50-100 parts by weight of bismaleimide resin, 20-100 parts by weight of an allyls compound and 1-30 parts by weight of a flexibilizer at the temperature of 50-200 DEG C; after dissolving and dispersing uniformly, cooling to the temperature of 70-150 DEG C; adding 0.1-10 parts by weight of an antioxidant and 0.1-20 parts by weight of an ultraviolet absorber; after dissolvingand dispersing uniformly, cooling to the temperature of 70-150 DEG C; adding 1-50 parts by weight of epoxy resin, 0.1-10 parts by weight of a coupling agent and 0.1-10 parts by weight of a thixotropicagent; and dispersing uniformly to obtain a resin composition; carrying out a coating procedure and a fiber compounding procedure on the resin composition, and curing to obtain the bismaleimide resinand epoxy resin composite material.
