摘要
以氰尿酸、二苯甲烷双马来酰亚胺、环氧树脂和潜伏性固化剂为原料,合成了一种新型耐热性树脂,并压制成型玻璃布层压板。该树脂溶液贮存稳定性好,易于成型加工。该树脂在150℃以上固化迅速,固化热焓达—179.5J/g,在170℃固化5h与在210℃固化4h有完全相同的热失重曲线。在170℃下压制的玻璃布层压板具有优良的高温介电性能和力学性能。
A new resin has been synthesized by copolymerization of cyanuric acid, 4, 4'-bismaleimidodiphenylmethane, epoxy resin and latent curing agent, and its glass cloth laminate has also been prepared. The resin solution not only had a good storage stablity, but also was easy to prepare glass cloth laminate. Theresin cured quickly above 150℃, and its curing heat enthalpy was -179.5J/g. The resin cured at 170℃ for 5h had the completely same thermogravimetric curve as cured at 210℃ for 4h.The laminate which had been prepared at 170℃ had both excellent dielectric and mechanical properties at high temperature.
