钕系顺丁橡胶在半钢子午线轮胎胎面胶中的应用

Application of Neodymium-based Cis-polybutadiene Rubber in Tread Compound of Semi-steel Radial Tire

研究钕系顺丁橡胶(BR)在半钢子午线轮胎胎面胶中的应用。结果表明,用牌号为CB24的钕系BR等量替代BR9000,胶料的耐磨性能和抗撕裂性能提高,生热减小,成品轮胎的制动性能提高,滚动阻力降低,符合轮胎节能、降耗的环保要求,轮胎性能大幅提高。

The application of neodymium-based cis-polybutadiene rubber (BR) in the tread compound of semi-steel radial tire was investigated. The results showed that, by using neodymium-based BR CB24 to equally replace traditional BR9000 in the tread compound, the wear resistance and tear resistance of the compound were improved, the heat build-up was reduced, the braking performance of the finished tire was improved, the rolling resistance was reduced, and the overall tire performance was greatly improved. The application of neodymium-based BR reduced the energy consumption of tire and met the requirements of environmental protection.
