High-hardness wear-resistant rubber shoe sole

Abstract

The invention discloses a high-hardness wear-resistant rubber shoe sole which is prepared from the following raw materials in parts by weight: 7-14 parts of natural rubber, 6-10 parts of sorbitan fatty acid ester, 9-15 parts of antimonous oxide, 5-10 parts of salicylic acid, 11-17 parts of triphenyl phosphite, 20-30 parts of heavy calcium carbonate, 9-18 parts of butadiene styrene rubber, 11-15 parts of magnesium oxide, 6-10 parts of white carbon black, 5-10 parts of zinc carbonate, 10-15 parts of stearyl alcohol polyglycol ether, 8-15 parts of zirconium fluoride, 7-14 parts of stearic acid, 6-9 parts of sulfur, 10-20 parts of high styrene, 8-15 parts of nano zinc oxide and 6-12 parts of solid coumarone. The shoe sole provided by the invention is relatively high in hardness; the ageing resistance and wear resistance of shoe rubber are greatly improved.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to a high-hardness wear-resistant rubber sole. Background technique [0002] Due to the rise of outdoor sports, adventure sports and other activities in recent years, as well as differences in regional conditions, and the need to adapt to extremely harsh low-temperature environments, new requirements have been put forward for some special functions of footwear. At present, outdoor products at ordinary prices can only meet the needs of general cold conditions. Under extreme cold conditions, the requirements for cold resistance and hardness of the soles are higher. However, the manufacturing process of previous snow mountaineering sports shoes is complicated, and the price of materials is very high. The market price is often ten times or even dozens of times that of ordinary shoes, and it is difficult to meet the needs of ordinary consumers. Therefore, looking for a cheap m...
