| 摘 要： | 采用真空灌注工艺,以磨碎玻璃纤维(MG)为填料,通过聚氨酯(PU)对4,5环氧环己烷1,2-二甲酸二缩水甘油酯(TDE-85)、四氢邻苯二甲酸二缩水甘油酯(711)、二酚基丙烷环氧树脂(E-51)改性,研究了MG/PU/TDE-85灌封材料、MG/PU/711灌封材料及MG/PU/E-51灌封材料的力学性能、热性能和电性能。研究结果表明,MG/PU/TDE-85灌封材料的拉伸强度、冲击强度、玻璃化转变温度、体积电阻率均为最大,分别达到79.72MPa、17.83kJ/m2、144℃和2.78×1015Ω.cm,具有最佳的综合性能。

| Abstract: | With polyurethane modification of diglycidyl-4,5-epoxycyclohexane-1,2-dicarboxylate (TDE-85),tetrahydrocannabinol glycidyl phthalate (711) and phenol-based epoxy propane (E-51),three epoxy resin encapsulating materials of MG/PU/TDE-85,MG/PU/711 and MG/PU/ E-51 were prepared by the reinforcement of milled glass fiber(MG) and vaccum priming. The mechanical properties,thermal properties and electrical properties of these encapsulating materials were studied. The results indicate that MG/PU/TDE-85 has the best ... |
