Wear-resisting sole material and preparation method thereof

The invention relates to a formula of a rubber sole material and an improvement of the preparation method of the rubber sole material. The wear-resisting sole material comprises the following components by weight percent: 50-60% of natural rubber 3L, 3-5% of accelerator, 40-45% of filler, 1-1.5% of hardener and 1.5-2% of vulcanizing agent, wherein the hardener is high styrene; and the acceleratoris the mixture of inorganic accelerator, polyethylene glycol, stearic acid, antioxidant and tackifier and the accelerator also contains organic accelerator which is perferably selected from accelerator D, accelerator M and accelerator DM. The sole material of the invention is prepared from good natural rubber by adding the accelerator with various functions; and the sole prepared from the material has light weight, good wear resistance, water resistance and good heat retention property and is suitable to be used as the sole of the shoe with high wear strength such as tennis shoe and outdoor sneaker.
