| 中文摘要: |
| 研究国产超级增粘树脂SL-T421在全钢载重子午线轮胎胎肩垫胶中的应用。结果表明：与进口超级增粘树脂Koresin相比，国产超级增粘树脂SL-T421的化学特性和相对分子质量分布相当，红外光谱基本吻合，耐高温和热稳定性较好；以国产超级增粘树脂SL-T421等量替代进口超级增粘树脂Koresin用于全钢载重子午线轮胎胎肩垫胶中，胶料的硫化特性和硫化胶的物理性能相当，表面粘性提高，同时可降低胶料成本。 |
| 英文摘要: |
| The application of domestic super tackifying resin SL-T421 in the shoulder pad compound of truck and bus radial tire（TBR） was studied.The results showed that compared with the imported super tackifying resin Koresin，the chemical properties and relative molecular weight distribution of domestic super tackifying resin SL-T421 were similar，the infrared spectra were basically consistent，and the high temperature resistance and thermal stability were better.The domestic super tackifying resin SL-T421 was used to replace the imported super tackifying resin Koresin by equal weight in the shoulder pad compound of TBR tire，the vulcanization characteristics of compound and physical properties of vulcanizate were equivalent，the surface viscosity was improved，and the compound cost could be reduced. |
