莱茵塑分ST在全钢巨型工程机械子午线轮胎胎面胶中的应用

Application of Aktiplast ST in Tread Compound of Giant All-steel Off-The-Road Radial Tire

研究莱茵塑分ST在全钢巨型工程机械子午线轮胎胎面胶中的应用。结果表明,在胎面胶中以莱茵塑分ST等量替代增塑剂A50P,胶料的焦烧时间延长,硫化速度加快,可明显改善白炭黑在胶料中的分散性,提高硫化胶的物理性能和耐磨性能,降低压缩生热。

The application of Aktiplast ST in the tread compound of giant all-steel off-the-road radial tire was investigated. The results showed that,by using Aktiplast ST instead of plasticizer ASOP by equal weight in the tread compound, the scorch time of the compound extended, the curing rate in creased, the dispersion of silica in the compound was improved significantly, the physical properties and wear resistance of the vulcanizates were improved,and the compression heat build-up decreased.
