The invention belongs to the technical field of composite materials, and relates to a formula for a low-heat-generation tire tread. The formula comprises natural rubber, wollastonite, carbon black, white carbon black, a coupling agent, stearic acid, zinc oxide, an anti-aging agent, an accelerant and sulphur. Due to the wollastonite, the temperature rise of the surface temperature and the center temperature of a vulcanized product is small when the vulcanized product bears an alternating load, the Mooney viscosity of a rubber compound tire tread is reduced, and meanwhile, good use performance of the rubber compound can be ensured, so a vulcanized product of a composite material prepared from the rubber compound generates less heat when bearing alternating load, and the temperature rise of the surface temperature and the center temperature of the product is small; and the rubber compound of the composite material has lower Mooney viscosity in a mixing stage, so power consumption during a production process can be reduced, the dispersion of a filler in a rubber system can be promoted, the vulcanized product has good mechanical properties, the quality of the final product can be ensured, environmental protection problems during the production process can be reduced, the production cost of the rubber product can be reduced, and economic and social benefits can be improved.

    本发明属于复合材料技术领域,涉及一种低生热轮胎胎面配方,包括天然橡胶、硅灰石、炭黑、白炭黑、偶联剂、硬脂酸、氧化锌、防老剂、促进剂和硫磺,由于硅灰石可以使硫化制品在承受交变载荷时的表面温度和中心温度的温升较小,在降低混炼胶门尼黏度的同时,又可保证胶料良好的使用性能,所以其制备的复合材料的硫化制品在承受交变载荷时产生的热量较少,制品的表面温度和中心温度的温升较小,在混炼阶段,复合材料的混炼胶具有较低的门尼黏度,能够降低生产过程中的功耗,促进填料在橡胶体系中的分散,硫化制品具有较好的力学性能,能够保证最终制品的质量,同时还可减轻生产过程的中的环保问题,降低橡胶制品的生产成本,提高经济和社会效益。
