摘　　要：研究补强树脂PFM-C在轿车子午线轮胎下三角胶中的应用。结果表明:在下三角胶中加入补强树脂PFM-C并适当调整炭黑及硫化体系用量,胶料的门尼粘度降低,门尼焦烧时间缩短,硫化速度加快,炭黑分散性提高,工艺性能良好;硫化胶的硬度、拉伸强度和拉断伸长率增大;成品轮胎的高速和耐久性能达到国家标准要求。The application of reinforcing resin PFM C in the apex compound of passenger car radial tire was investigated. The results showed that,by using reinforcing resin PFM-C and properly adjusting the addition levels of carbon black and curing additives in the compound,the Mooney viscosity of the compound decreased,the Mooney scorch time was shortened, the curing rate increased, the dispersion of carbon black was improved and the processability of the compound was good. The hardness, tensile strength and elongation at break of the vulcanizate increased. The high speed performance and endurance of the finished tire met the requirements of national standards.
