摘　　要：采用低生热填料制备低生热聚氨酯(PU)胶料,考察炭黑、白炭黑和低生热填料对PU胶料性能的影响。结果表明:低生热填料可以提高PU胶料的硫化速度,降低门尼粘度,降低生热;仅添加低生热填料的PU胶料物理性能较差,添加白炭黑/低生热填料(并用比30/10)的PU胶料物理性能较好。The polyurethane （PU） compound with the characteristics of low heat buildup was prepared by using low heat buildup filler, and the influence of carbon black, silica and low heat buildup filler on the properties of PU compounds was investigated. The results showed that, with the low heat buildup filler, the curing speed of PU compound increased, the Mooney viscosity decreased, and the heat buildup was reduced. However, the physical properties of PU filled only with low heat buildup filler were poor. It was found that by using blended filler of silica and low heat buildup filler at the ratio of 30/10, the physical properties of PU compound were good.
