The invention provides a rubber composition as well as a preparation method and application thereof. According to the rubber composition, the carbon black is used for reinforcing, a low-sulfur vulcanization system is adopted, and the multifunctional cross-linking agent shown in the formula I is matched, so that the change rates of the performances (tensile strength, elongation at break and tearing strength) of the aged rubber are relatively small. Tests show that the heating performance Tan delta 60 DEG C of the rubber composition is reduced to 0.08, and the tire can be ensured to have good low rolling resistance performance. And meanwhile, the tire cannot be torn when the rim is disassembled and assembled. In addition, the preparation method of the rubber composition provided by the invention is simple and convenient, easy to implement and beneficial to industrial production. # imgabs0 #
本发明提供了一种橡胶组合物及其制备方法和应用。所述橡胶组合物通过使用炭黑补强,采用低硫黄的硫化体系,搭配式Ⅰ所示的多功能交联剂,可以保证老化后的橡胶性能(抗拉强度,断裂伸长率,撕裂强度)的变化率均较小。经测试,所述橡胶组合物的发热性能Tanδ60℃降低至0.08,可以保证轮胎具有良好的低滚阻性能。同时,轮胎在拆装轮辋的时候不会被撕裂。另外,本发明提供的上述橡胶组合物的制备方法简单方便,容易实现,有利于产业化生产。#imgabs0#
