| 中文摘要: |
| 在RD-F机械化学法活化胶粉的过程中，高速搅拌器使活化剂在胶粉表面涂覆均匀，开炼机对胶粉产生强烈的剪切细化作用，促进活化剂同胶粉结合。活化剂中，硫化剂提高胶粉-基质胶相界面的交联密度，塑解剂促进胶粉表面塑化，防老剂提高胶料动态性能，酚醛树脂进一步增强胶粉-基质胶相界面“粘合”。确定RD-F活化剂体系为：防老剂RD 1，酚醛树脂 1，420#油 1.5，促进剂H 0.4，硫黄 0.5，促进剂CZ 0.5，乙烯焦油 8。RD-F活化剂体系活化的胶粉能较大地提高胎面胶料的耐磨性。 |

| The activator is uniformly applied to the surface of crumb rubber with a high speed agitator，the strong shearing and fine grinding effect is applied to the crumb rubber by an open mill to facilitate the bonding between activator and crumb rubber.The activator is composed of curing agent，peptizer，antioxidant and phenolic resin.The curing agent is used to increase the crosslink density at the interface between crumb rubber and rubber matrix；the antioxidant is used to increase the dynamic properties of the compound；the phenolic resin is used to increase the “adhesion” at the interface between crumb rubber and rubber matrix.RD-F activator system include antioxidant RD l，phenolic resin l，420# oil l.5，accelerator H 0.4，sulfur 0.5，accelerator CZ 0.5，vinyl tar 8.The wear resistance of tire tread can be significantly improved by using the crumb rubber activated with RD-F activator system. |
