The invention belongs to the technical field of tires, and discloses a rubber composition for a wear-resistant tire, which comprises 10 to 50 phr of polyisoprene rubber, 10 to 50 phr of polybutadiene rubber, 10 to 50 phr of butadiene-styrene copolymer, 5 to 25 phr of syn-1, 2 polybutadiene, 10 to 30 phr of carbon black and 40 to 100 phr of white carbon black. The rubber composition provided by the invention not only can effectively improve the wear resistance of the tire, but also can reduce the rolling resistance.
本发明属于轮胎技术领域,公开了一种耐磨轮胎用橡胶组合物,包括10-50phr聚异戊二烯橡胶、10-50phr聚丁二烯橡胶、10-50phr丁二烯-苯乙烯共聚物、5-25phr间同1,2聚丁二烯、10-30phr炭黑,40-100phr白炭黑。本发明的橡胶组合物不仅可以有效改善轮胎的耐磨性,同时还能降低滚动阻力。
