| 中文摘要: |
| 研究4种增粘树脂（A-90树脂、203树脂、古马隆树脂和Koresin树脂）及增粘树脂并用体系（A-90树脂/Koresin树脂和古马隆树脂/Koresin树脂并用体系）对硫醇调节型氯丁橡胶（CR）胶料性能的影响。结果表明：4种增粘树脂及增粘树脂并用体系的加入使胶料的门尼粘度降低，门尼焦烧时间延长，A-90树脂及增粘树脂并用体系的加入增大了硫化胶的交联密度；4种增粘树脂及增粘树脂并用体系的加入对硫化胶的硬度和拉伸强度影响不明显，使硫化胶的拉断伸长率增大，回弹值减小，古马隆树脂/Koresin树脂并用体系的加入增大了硫化胶的300%定伸应力，提高了硫化胶的耐热氧老化性能，保持了硫化胶的减震性能；4种增粘树脂及增粘树脂并用体系的加入提高了硫化胶的粘合性能，加入古马隆树脂和A-90树脂的硫化胶的粘合强度较大。 |

| The effects of the four tackifying resins（A-90 resin，203 resin，coumarone resin and Koresin resin）as well as the tackifying resin blends（A-90 resin/Koresin resin and coumarone resin/Koresin resin blends）on the properties of thiol-regulated CR compounds were studied.The results showed that the addition of the four tackifying resins and the tackifying resins blends reduced the Mooney viscosities of the compound and extended the Mooney scorch time.The addition of the A-90 resin and the tackifying resin blends increased the crosslink densities of the vulcanizates.The addition of the four tackifying resins and the tackifying resin blends had little affect on the hardness and tensile strength of the vulcanizates，but increased the elongations at break and reduced the rebounds.The addition of the coumarone resin/Koresin resin blend increased the 300% modulus of the vulcanizates，enhanced the heat-aging resistance，and maintained the damping performance.The addition of the four tackifying resins and the tackifying resin blends improved the adhesive performance of the vulcanizates，and the adhesive strengths of the vulcanizates with coumarone resin and A-90 resin were higher. |
