| 中文摘要: |
| 研究环保型白炭黑分散剂AT-BTP在半钢子午线轮胎胎面胶中的应用，并与含锌白炭黑分散剂AT-BTJ进行对比。结果表明：白炭黑分散剂AT-BTP为不含锌的偶联活性剂和多元醇酯的复合物，可以提高白炭黑在胶料中的分散性；与未添加白炭黑分散剂的胶料相比，添加白炭黑分散剂AT-BTP和AT-BTJ的胶料门尼粘度降低，Fmax增大，硫化速度提高，300%定伸应力略有提高，耐磨性能改善，生热降低，耐热老化性能较好；白炭黑分散剂AT-BTP对胶料硫化特性的影响较白炭黑分散剂AT-BTJ小，且其胶料生热低，耐磨性能和耐屈挠性能好。 |
| 英文摘要: |
| The application of environmentally-friendly silica dispersing aid AT-BTP in the tread compound of steel-belted radial tire was studied and compared with silica dispersing aid AT-BTJ. Silica dispersing aid AT-BTP was a complex of zinc-free coupling agent and polyol ester，which could improve silica dispersion in the compound. Compared with the silica filled compound without silica dispersing aid，the Mooney viscosity of the compound with silica dispersing aid AT-BTP or AT-BTJ was lower，Fmax was higher，curing rate was higher，the tensile modulus at 300% elongation of the vulcanized compound was higher，the abrasion resistance was improved，heat build-up was reduced，and heat aging resistance was better. Compared with silica dispersing aid AT-BTJ，the influence of silica dispersing aid AT-BTP on the curing characteristics of the compound was smaller，the heat build-up of the compound with silica dispersing aid AT-BTJ was lower，and the abrasion resistance and flex resistance were better. |
