摘要:制备了双(N-间乙炔基苯基邻苯二甲酰亚胺)醚(BE)改性甲基二苯乙炔基硅烷(MDPES)(BE/MDPES)。研究表明,选择BE/MDPES的固化温度时,必须同时考虑网络的形成反应和BE中醚键的断裂反应。当最终固化温度控制在300℃时,mBE/mMDPES=4/5的玻璃纤维复合材料的弯曲强度高达275 MPa,235℃时的高温弯曲强度为241 MPa,保留率达88.5%,且优异的耐热性能与介电性能保持不变。
MDPES was modified with bis ( N-m- acetylenephenylphthalimide)ether (BE) . The experimental results show that the curing temperature of the modified MDPES for making the composite mainly depend on both the reaction of network formation and the cleavage of the ether linkages in BE. The flexural strength of the composite made of the glass fiber and modified MDPES (BE/MDPES=4/5, mass ratio), cured finally at 300℃ is as high as 275 MPa, and that at high temperature (235℃ ) is 241 MPa and the remaing percentage of the flexural strength is as high as 88.5%, exhibiting the excellent heat-resistant properties.
