The embodiment of the invention relates to the technical field of tires, and particularly discloses a rubber composition as well as a preparation method and application thereof, and the rubber composition comprises the following raw materials: natural rubber, polybutadiene rubber, carbon black, zinc oxide, stearic acid, an anti-aging agent, microcrystalline wax, a resin additive, oil, an accelerant, sulfur and modified carbon nanotubes. According to the embodiment of the invention, the neodymium-based high cis-polybutadiene rubber is used to reduce the heat generation of the rubber composition to a certain extent, and the modified carbon nanotubes are added to reduce the use amount of the carbon nanotubes, so that the conductivity of the rubber composition is greatly improved on the basis of not influencing other properties, the heat generation can be reduced, and the service life of the rubber composition is prolonged. The problems that in the existing tire processing technology, the conductivity cannot be greatly improved and heat generation cannot be reduced on the basis that other performance is not affected are solved. Moreover, the preparation method provided by the embodiment of the invention is simple and has a wide market prospect.

    本发明实施例涉及轮胎技术领域,具体公开了一种橡胶组合物及其制备方法和应用,所述橡胶组合物包括以下的原料:天然橡胶、聚丁二烯橡胶、炭黑、氧化锌、硬脂酸、防老剂、微晶蜡、树脂添加剂、油、促进剂、硫磺以及改性碳纳米管。本发明实施例通过使用钕系高顺式聚丁二烯橡胶以在一定程度上降低橡胶组合物的生热,同时添加改性碳纳米管来降低碳纳米管的使用量,在不影响其它性能的基础上大幅提高橡胶组合物的电导率,同时也能降低生热,解决了现有轮胎加工技术中存在无法在不影响其它性能的基础上大幅提高电导率且降低生热的问题。而且,本发明实施例提供的制备方法简单,具有广阔的市场前景。
