摘　　要：用激光导热分析仪测量了N234/N539炭黑填充胶的热扩散系数,研究了炭黑品种及炭黑填充量对热扩散系数的影响。实验结果表明,炭黑的内部结构特性对胶料热扩散性能影响显著,炭黑的粒径越小,比表面积越大,热扩散系数越大;随着炭黑填充量的增加,胶料的热扩散系数增大,但由于炭黑在胶料中分散程度的不同和包容胶的存在,使得在某些炭黑填充量下,胶料的热扩散系数有所下降。Thermal diffusivity coefficient of the rubber is measured by thermal conductivity equipment. The influence of carbon species and filling amount on thermal diffusivity coefficient is studied and analyzed. The result indicates that rubber diffusivity property is influenced obviously by carbon inner structure, if the carbon particle is very small then the surface area will increase, so thermal diffusivity coefficient will increase. With increasing the carbon filled amount increasing, rubber diffusivity coefficient will increase, but due to the fact that carbon has different disperse degrees when mixed in the rubber and existed some of the containing rubber, rubber diffusivity coefficient will decrease in some carbon-filled conditions.
