Abstract

The effects of thiodiphenol based epoxy resin on the thermal property of the composites containing aluminum oxide were investigated. The thermal conductivities and thermal diffusivities of the composites were dependent on the polymer resin. At the same content of Al₂O₃, the thermal conductivity and thermal diffusivity of composites made by synthesized polymer resin exhibited higher than that of composite made by bisphenol-A resin. The obtained maximum thermal conductivity of the composite was 0.25 W/mK, which was 0.4 times as large as that of the conventional bisphenol-A epoxy resin which has an amorphous structure. It is supposed that the reason for the high heat conductivity obtained in thiodiphenol based epoxy resin is certain high packing structure.

摘要

研究了基于硫代双酚的环氧树脂对含氧化铝复合材料热性能的影响。复合材料的热导率和热扩散率取决于聚合物树脂。在相同的Al₂O₃含量下，由合成聚合物树脂制成的复合材料的热导率和热扩散率高于由双酚A树脂制成的复合材料。所获得的复合材料的最大热导率为0.25W/mK，是具有无定形结构的传统双酚A环氧树脂的0.4倍。据推测，基于硫代双酚的环氧树脂获得高导热率的原因是某种高堆积结构。
