【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。更多还原

【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.更多还原
