摘　　要：试验研究液体橡胶LBR307在轿车子午线轮胎胎面胶中的应用。结果表明,采用5份LBR307等量替代BR用于轿车子午线轮胎胎面胶,胶料的门尼粘度和ML减小,门尼焦烧时间和t90延长,加工工艺性能改善,硫化胶的定伸应力和拉伸强度减小,拉断伸长率、拉断永久变形和压缩生热增大,抗湿滑性能提高;成品轮胎的耐久性能、低气压性能和速度性能均达到企业标准要求。The application of liquid rubber LBR307 in tread compound of PCR tire was experimentally investigated. The results showed that,by using 5 phr LBR307 instead of BR by equal weight in tread compound of PCR tire,the Mooney viscosity and ML of compound decreased,the Mooney scorch time and t90 prolonged, the processing properties improved, the modulus and tensile strength of vulcanizate decreased, the elongation at break, tensile set at break and compression heat build-up increased, the wet skid resistance improved, the endurance, tow pressure and speed performance of the finished tire met the requirements of enterprise standards.
