Abstract

The invention discloses a wear-resistant sole material which is prepared from standard rubber, styrene-butadiene rubber, cis-1,4-polybutadiene rubber, white carbon black, diethylene glycol, butter, tire black powder, HP-669, zinc oxide, stearic acid, antifogging agent, dispersing agent, accelerator, anti-aging agent, RX-80 and high styrene resin. The preparation method of the wear-resistant sole material comprises the following steps: evenly mixing the materials, adding into a Banbury mixer, banburying, adding the banburying mixture into a screw extruder, carrying out melt blending, granulating, mixing the granules in an open mill, and carrying out mold pressing to obtain the wear-resistant sole material. The wear-resistant sole material disclosed by the invention enhances the heat flowability of the rubber material in the die; and the wear-resistant sole material avoids rising the mold due to thickening, and reduces the burr weight of the product, thereby saving the cost and enhancing the yield of the product. The product prepared from the wear-resistant sole material disclosed by the invention has the advantages of favorable wear resistance, favorable resilience and excellent flex crack resistance.

Description

technical field [0001] The invention relates to a shoe sole material, in particular to a wear-resistant shoe sole material and a preparation method thereof. Background technique [0002] Shoes are items that are often used in our daily life, and soles are an essential part of making shoes. At present, some soles on the market are too heavy due to the lack of formula used. If the produced soles are lighter in quality, the related properties, such as wear resistance and compression resistance, will be reduced, which cannot satisfy people. needs. [0003] With the development of science and technology and the progress of society, people's living standards continue to improve. Improving the quality and performance of all kinds of shoes and making the wearers safer and more comfortable is the ultimate goal and direction of the entire shoe industry. [0004] Materials currently used to make soles include rubber, thermoplastic elastomers, plastics, and the like. Among them, the ...
