| 摘 要： | 介绍了双马来酰亚胺（BM I）/二烯丙基双酚A（DABPA）/环氧树脂（E-51）耐高温胶粘剂体系的制备,选择BM I/DAB-PA/E-51三元体系的最佳配比,进行力学性能,粘接性能,DMA,TG等测试,表征了改性胶粘剂的综合性能。试验结果表明：当BM I/DABPA/E-51的质量比为4：1：1时,胶粘剂体系在250℃时,拉伸强度仍有5.8MPa,适合于做耐高温结构胶。

| Abstract: | The preparation of bismaleimide（BMI）/ortho-diallyl bisphenol A（DABPA）/epoxide（E-51） resin systems was discussed,and the best ratio of BMI/DABPA/E-51 ternary system was chosen for mechanical properties,adhesive properties,DMA,TG and other tests to characterize the overall performance of modified adhesive.The results showed that when the ratio（wt） of BMI/DABPA/E-51 was 4：1：1,the tensile strength of the adhesive system was still 5.8MPa in 250℃,and it was suitable for being heat-resistant structural adhesive. |
