摘　　要：研究不同功能型树脂对轿车子午线轮胎胎面胶性能的影响。结果表明:在胎面胶中加入抗湿滑树脂和C5树脂,胶料的拉伸强度和拉断伸长率增大,DCPD树脂胶料的抗撕裂性能最优;抗湿滑树脂可以改善胶料的耐磨性能,且动态性能具有良好的平衡性,C5树脂胶料0和60℃时的损耗因子(tanδ)同时增大,DCPD树脂胶料60℃时的tanδ增大;以12份4401树脂替代8份环保油V700,胶料的门尼焦烧时间延长,硫化胶的拉伸强度和拉断伸长率增大,耐磨性能和抗湿滑性能提高,成品轮胎的抗干、湿滑性能提高,滚动阻力相当。The effects of different functional resins on the performance of the tread compound of passenger car radial tire were investigated. The results showed that by adding anti-skid resin and C5 resin in the tread compound,the tensile strength and elongation at break of the compound increased,and the tear resistance of the compound with DCPD resin was the best. The anti-skid resin could improve the wear resistance of the compound,and the dynamic properties had a good balance. The loss factor(tanδ) of the compound with C5 resin at 0 and 60 ℃ increased simultaneously,while the tanδ at 60 ℃ of the compound with DCPD resin increased.By using 12 phr 4401 resin instead of 8 phr environmentally friendly oil V700,the Mooney scorch time of the compound was prolonged,the tensile strength and elongation at break of the vulcanizate were increased,the wear resistance and wet skid resistance were improved,the dry and wet skid resistance of the finished tire were improved,and the rolling resistance was equivalent.
