摘要
研究废旧轮胎裂解炭黑(CBp)在半钢子午线轮胎胎面胶中的应用。结果表明:随着CBp用量的增大,胶料的交联密度增大,焦烧时间缩短,硫化速度加快;硫化胶的硬度和定伸应力增大,拉伸强度和撕裂强度减小,耐磨性能下降,储能模量和损耗模量增大,0℃时的损耗因子(tanδ)先增大后减小,60℃时的tanδ呈增大趋势;胶料的成本降低。
The application of pyrolytic carbon black(CBp)from waste tires in the tread compound of steel-belted radial tire was investigated.The results showed that,as the addition level of CBp increased,the crosslinking density of the compound increased,the scorch time was shortened,and the curing speed increased.The hardness and modulus of the vulcanizate increased,the tensile strength,tear strength and wear resistance decreased,the storage modulus and loss modulus increased,the loss factor(tanδ)at 0℃increased at first and then decreased,and the tanδat 60℃tended to increase.The cost of the compound was reduced.
