中文摘要：

研究低相对分子质量树脂对天然橡胶/顺丁橡胶/乳聚丁苯橡胶复合材料加工性能、物理性能和动态粘弹性能的影响.结果表明：加入低相对分子质量树脂可使胶料的门尼粘度下降,且其降幅与树脂的相对分子质量有密切关系;填充树脂后胶料的强伸性能稍有下降,硬度和拉断永久变形基本不变;动态压缩温升改善,耐磨性能变化不大;TL-L1100树脂、TL-1000树脂以及C5石油树脂加入到橡胶中改善了胶料的抗湿滑性能和抗冰滑性能.

英文摘要：

The influence of low molecular weight resins on the processing properties,physical properties and dynamic viscoelastic properties of natural rubber/butadiene rubber/emulsion polymerized styrene butadiene rubber composites was studied. The results showed that, with the addition of low molecular weight resins, the Mooney viscosity of the compound decreased and the extent of decrease highly depended on the molecular weight of resins. The tensile properties of the resin filled vulcanizate decreased a little, the hardness, permanent tensile set and abrasion resistance changed little, and dynamic compression heat build- up was reduced. By using TL-L1100 resin, TL-1000 resin and C5 petroleum resin, the wet skid resistance and ice skid resistance of the compound were improved.
