摘　　要：研究补强树脂SP6701在跑气保用轮胎胎侧支撑胶中的应用。结果表明:在胎侧支撑胶中加入补强树脂SP6701,胶料的门尼粘度减小,焦烧时间和硫化时间延长;硫化胶的邵尔A型硬度、100%定伸应力和拉伸强度增大,压缩生热降低;成品轮胎的耐久性能提高。The application of reinforcing resin SP6701 in the sidewall compound of run-flat tire was investigated. The results showed that, by adding reinforcing resin SP6701 in the sidewall compound, the Mooney viscosity of the compound decreased, the scorch time and cure time extended. The Shore A hardness,tensile stress at 100% strain and tensile strength of the vulcanizate with SP6701 increased, and the compression heat build-up decreased. The endurance of the finished tire was improved.
