摘　　要：通过力学性能及热性能测试研究了不同环氧树脂、固化剂、填料对环氧灌封料性能的影响,结果表明:选用纳米橡胶改性环氧树脂与脂肪族环氧树脂,改性甲基六氢苯酐固化剂及600目硅灰石与有机膨润土填料制备的环氧灌封材料热变形温度可达到190℃以上,弯曲强度达到92 MPa,冲击强度15.5 kJ/m2。The effects of different epoxy resins,curing agents and fillers on the performance of epoxy potting compounds were investigated by the testings of mechanical properties and thermal properties. The results showed that the heat distortion temperature,flexural strength and impact strength of the epoxy potting compounds prepared with nano-rubber-modified epoxy resin and aliphatic epoxy resins,modified methyl hexahydrophthalic anhydride curing agent,organic bentonite and 600 mesh wollastonite fillers were up to above 190 ℃,92 MPa and 15. 5 kJ /m2,respectively.
