摘　　要：以天然橡胶(NR)为主体,添加炭黑、分散剂SDS等其它助剂制成混炼胶,考察了不同用量的分散剂SDS对NR胎面胶性能的影响。结果表明,炭黑分散剂SDS用量为2份时,混炼胶的各项物理性能均较好,硫化时间缩短了27%,拉伸强度提高了13.7%,断裂伸长率为550%,邵尔A硬度为63,阿克隆磨耗体积减小了2%;老化后其性能仍为最佳。硫化胶的滚动阻力和生热均降低,Payne效应更为明显,填料的分散程度较高,这对胎面胶的加工生产具有重要意义。In this paper,using NR as the matrix,the carbon black,dispersant SDS and other additives were made of compound rubber,then studied the effect of different dosage dispersant SDS on properties of NR tread rubber.The results showed that the physical properties of the NR rubber were well when dispersant SDS was 2 phr,the vulcanization time was shortened by 27%,and the tensile strength was increased by 13.7%than that of the no dispersant.Elongation at break was 550%,Shore A hardness was 63,the volume of Akron wear reduced by 2%;After aging,property of the rubber added dispersant SDS was still the best.Vulcanized rubber rolling resistance and heat were reduced,Payne effect was more obvious,the dispersed degree of the filler was higher.In summary,it was great significance for tread rubber processing and production.
