The invention provides an ultrahigh-thermal-conductivity all-steel radial giant tire tread rubber material and a preparation method thereof. The tread rubber material is prepared from raw rubber, a heat conduction agent and other assistants, and the heat conduction agent is alumina. Compared with an existing tread formula technology, aluminum oxide is adopted as a heat conduction agent, so that the physical and mechanical properties of the tread rubber can meet the use requirement of the tire tread of an all-steel radial giant tire, the heat conductivity coefficient of the tire tread rubber can be increased, the tire tread rubber has ultrahigh heat conduction performance, the temperature difference between the inside and outside of the tread rubber can be shortened, and the time for the inside temperature to reach the vulcanization temperature is shortened, so that the performance of the whole tire in early and later use stages is consistent. The invention belongs to the field of tire production and manufacturing.
本发明提供一种超高导热率全钢子午巨胎胎面胶料及其制备方法,该胎面胶料由生胶和导热剂及其他助剂制备而成,所述导热剂为氧化铝,与现有的胎面配方技术相比,本发明采用氧化铝作为导热剂,从而既使胎面橡胶的物理机械性能能够满足全钢子午巨胎轮胎胎面使用,又能提升轮胎胎面橡胶的导热系数,使其具备超高导热的性能,巨胎胎胚在硫化时,能够缩短胎面胶料内外温差、减少内部温度达到硫化温度的时间,从而使得整个轮胎的使用早期和后期的性能表现一致。属于轮胎生产制造领域。
