摘　　要：研究芳纶短纤维在泥地轮胎胎面胶中的应用。结果表明:与未添加芳纶短纤维的胶料相比,添加芳纶短纤维的胶料焦烧时间和正硫化时间略有延长,硫化返原时间呈缩短趋势;硫化胶的抗切割和抗刺扎性能明显提高,损耗因子减小,剪切温升明显降低;当芳纶短纤维用量为3份时性能最佳;成品轮胎的耐久性能随着芳纶短纤维用量增大而提高。The application of short aramid fiber in the tread compound of mud tire was investigated.The results showed that,compared with the compound without short aramid fiber,the scorch time and optimum curing time of the compound with short aramid fiber were slightly longer,and the reversion time was shortened. The cutting resistance and puncture resistance of the vulcanizate with short aramid fiber were significantly improved,the loss factor was reduced,and the shear temperature rise was significantly reduced.When the amount of short aramid fiber was 3 phrs,the overall property of the vulcanizate was the best. The durability of the finished tire increased with the amount of short aramid fiber increased.
