环保型硫化剂WK-7在全钢子午线轮胎胎面基部胶中的应用

Application of Environmentally Friendly Curing Agent WK-7 in the Tread Base Compound of TBR Tire

研究硫化剂DTDM的替代产品环保型硫化剂WK-7在全钢子午线轮胎胎面基部胶中的应用。结果表明:与硫化剂DTDM胶料相比,硫化剂WK-7混炼胶的硫化返原率略有减小,硫化速率增大,交联密度减小;硫化胶的耐热空气老化性能相当,生热略有升高;成品轮胎的耐久性能相当。硫化剂WK-7可作为硫化剂DTDM的环保替代产品应用于全钢子午线轮胎胎面基部胶中。

In this study,the application of curing agent WK-7 in the tread base compound of TBR tire was investigated. Curing agent WK-7 was an environmentally friendly alternative curing agent to replace conventional curing agent DTDM. The results showed that compared with the curing agent DTDM cured rubber,the reversion rate of the compound using curing agent WK-7 was slightly reduced,cure rate increased and crosslinking density decreased,the hot air aging resistance of the vulcanizates was similar while the heat build-up increased slightly,the durability of the finished tire was unchanged. It was demonstrated that curing agent WK-7 could be used as an environmentally friendly curing agent to replace curing agent DTDM in the tread base compound of TBR tire
