| 中文摘要: |
| 研究橡胶增粘剂ZD-95在半钢子午线轮胎三角胶中的应用。结果表明：在半钢子午线轮胎三角胶中使用1.5～3.5份橡胶增粘剂ZD-95替代2.5份C5/C9共聚树脂，胶料的自粘性均提高，自粘性保持率较高；用2.5份橡胶增粘剂ZD-95等量替代C5/C9共聚树脂，胶料的自粘性提高，门尼粘度降低，拉伸强度和拉断伸长率提高，工艺性能满足生产要求，成品轮胎的高速性能和高速耐久性能达到企业标准要求，且胶料成本降低。 |
| 英文摘要: |
| The application of rubber tackifier ZD-95 in the bead filler of steel-belted radial tire was studied.The results showed that，using 1.5～3.5 phr rubber tackifier ZD-95 to replace 2.5 phr C5/C9 copolymer resin，the tackiness of compounds were improved and the tackiness retention rate were higher.When 2.5 phr C5/C9 copolymer resin was replaced by the same amount of rubber tackifier ZD-95，the tackiness of the compound increased，the Mooney viscosity of the compound decreased，the tensile strength and elongation at break of the vulcanizate increased，the processing properties met the production demands，the high-speed performance and high-speed durability of the finished tire met the requirements of the enterprise standards，and the cost of compound was reduced. |
