Disclosed is a rubber composition for tire treads and a tire manufactured using the same. More particular, the rubber composition for tire treads includes 50 to 200 parts by weight of a wet masterbatch prepared by reacting a styrene-butadiene latex, a carbon black and a liquid styrene-butadiene copolymer at 50 to 95°C for three to nine hours according to a batchwise method, 60 to 70 parts by weight of a raw rubber, and 50 to 200 parts by weight of a carbon black. Accordingly, the rubber composition for tire treads has enhanced grip and anti-wear performances under a condition of heavy load, high slip and high speed, and thus, may be usefully used in manufacturing a ultra-high performance tire.
本发明公开了一种用于轮胎胎面的橡胶组合物以及使用该组合物制造的轮胎。更具体地说,轮胎胎面用橡胶组合物包括 50 至 200 份(按重量计)湿母料、60 至 70 份(按重量计)生橡胶和 50 至 200 份(按重量计)炭黑,湿母料的制备方法是将苯乙烯-丁二烯胶乳、炭黑和液态苯乙烯-丁二烯共聚物按批次法在 50 至 95°C 下反应 3 至 9 小时。因此,用于轮胎胎面的橡胶组合物在重载、高滑和高速条件下具有更强的抓地力和抗磨损性能,可用于制造超高性能轮胎。
