摘　　要：综述了导热橡胶的典型理论模型和导热机理,并对国内外导热硅橡胶的研究现状做了详细介绍。硅橡胶的导热性主要取决于硅橡胶基体、填料、以及加工工艺三个方面的因素。填料的导热性、添加量及其在基体中的分布形式对硅橡胶的导热性能起着关键作用。The typical theory model and thermal conducting mechanism of thermal conductive silicone rubber were summarized. Meanwhile, the present status of thermal condu-ctive silicone rubber in country and overseas was introduced in detail. Silicone rubber matrix, fillers and process technology were main facts which defined the thermal conductive properties of silicone rubber. However, the conductive properties, adding volume and dissipation types of fillers were critical facts.
