摘　　要：利用自制潜伏性催化剂加入经过增韧的氰酸酯树脂与环氧树脂共聚改性体系中制备出中温固化氰酸酯胶膜。通过DSC、DMA、IR对中温固化氰酸酯胶膜固化进行了研究,用流变仪对其贮存期与流变规律及其性能进行了研究,用万能拉力机研究了力学性能,以介电测试仪对其介电性能进行研究。该胶膜经135℃/4h固化,具有良好的力学性能,测试频率为9.375GHz时,胶膜的介电常数为2.7,介电损耗为0.007,具有良好贮存性。研究结果表明自制催化剂降低了氰酸酯胶膜的固化温度,实现了130~135℃固化。The moderate temperature curing cyanate ester film is prepared by adding the self-made latent catalyst into the toughened cyanate es-ter resin and epoxy resin copolymerization system. This cyanate ester film are studied by DSC, DMA and IR. The storage period and rheological rule of the product is studied by the rheometer. The mechanical properties are studied by the universal tensile machine. The study on the dielectric proper-ties is carried out with dielectric tester. The adhesive film is cured at 135℃/4 h, and has good mechanical properties. Under the frequency of9.375 GHz, the dielectric constant of the adhesive film is 2.7 and the dielectric loss tan δ is 0.007. The results show that it has a good storage property.And the curing temperature of cyanate ester film is reduced by using the self-made catalyst which is 130~135 ℃.
