摘　　要：探讨导热助剂和填料对胶料导热性能的影响。结果表明:导热增强剂TB-1对橡胶的补强作用和导热效应优于氧化锌、三氧化二铁、三氧化二铝,可以用作导热型补强助剂;用于轮胎胎侧胶和胎体胶,可以提高胶料的导热性能,对胶料物理性能影响不大;用于水胎胎体胶,可以提高水胎传热速度,缩短硫化时间,提高硫化效率,降低硫化能耗。不同种类的炭黑对胶料导热性能影响不同;炭黑用量增大,胶料的导热系数增大。The influence of additives and fillers on the thermal conductivity of rubber was investigated. The results showed that the effect of thermal conductivity enhancer TB- 1 on the reinforcement and thermal conductivity of rubber compounds was superior to zinc oxide, ferric oxide and aluminum oxide. TB-1 could be used as thermal conductive reinforcing additive for rubber. The thermal conductivity of tire sidewall and carcass compounds was improved by using TB-1, while the physical properties changed little. During water bag curing, the heat transfer rate was increased, the curing time was shortened, and thus the curing efficiency was increased, the energy consumption was reduced. In addition, the influence of different types of carbon black on the thermal conductivity of rubber was different, but with the increase of the loading level of carbon black, the thermal conductivity generally increased.
