| 中文摘要: |
| 研究增效剂CST812在全钢载重子午线轮胎胎面胶中的应用。结果表明：直接添加增效剂CST812后，胶料的定伸应力提高，生热和滞后损失有一定程度的降低；用白炭黑等量替代部分炭黑，增大增效剂CST812的用量后，填料的分散性改善，胶料的邵尔A型硬度和定伸应力基本相当或略有提高，生热、滞后损失和损耗因子明显降低，耐磨性能有一定程度提高，但抗切割性能降低；增效剂CST812用量为0.8份时，胶料的综合性能最好。 |
| 英文摘要: |
| The application of synergist CST812 in the tread compound of truck and bus radial tire was studied.The results showed that，after adding synergist CST812 directly，the modulus of the compound increased，and the heat generation and hysteresis loss decreased to a certain extent.Replacing part of carbon black with silica in the same amount and increasing of the amount of synergist CST812，the dispersion of the filler was improved，the shore A hardness and modulus of the compound were basically the same or slightly increased，the heat generation，hysteresis loss and loss factor significantly decreased，the wear resistance was improved to a certain extent，but the cutting resistance was reduced.When the amount of synergist CST812 was 0.8 phr，the comprehensive performance of the compound was the best. |
