摘　　要：研究新型生物基无锌白炭黑分散剂SL-5048(简称SL-5048)在轿车轮胎胎面胶中的应用。结果表明:在胎面胶中以SL-5048部分或全部等量替代白炭黑分散剂AT-BTH,可以改善白炭黑的分散性,胶料的门尼粘度减小,压缩生热和滚动阻力降低,耐磨性能、抗切割性能和抗湿滑性能提高;成品轮胎的充气外缘尺寸、高速性能、耐久性能和强度性能均达到国家标准要求,且生产成本降低。The application of a novel bio-based zinc-free silica dispersant SL-5048(abbreviated as SL-5048)in the tread compound of passenger car tires was studied.The results showed that by partially or completely replacing the silica dispersant AT-BTH with SL-5048 equivalently in the tread compound,the dispersibility of silica could be improved,the Mooney viscosity of the compound decreased,the compression heat build-up and rolling resistance were reduced,and the wear resistance,cutting resistance and wet slip resistance were improved.The inflated peripheral dimension,high-speed performance,durability and strength performance of the finished tire met the requirements of national standards,and the production cost was reduced.
