| 中文摘要: |
| 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。 |
| 英文摘要: |
| The application of a new type bio based zinc free silica dispersant SL-5048（abbreviated as SL-5048） in the tread compound of passenger car tire 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 reduced，and the wear resistance，cutting resistance and wet slip resistance were improved.The the inflated peripheral dimention，high-speed performance，durability and strength performance of the finished tire met the requirements of national standards and the production cost was reduced. |
