Abstract

The invention discloses a superwear-resisting rubber formulation of sport sole, which is characterized in that the formulation according to parts by weight comprises 80 parts of polybutadiene rubber, 20 parts of natural gum STR-5L, 1 part of uniform tackiness resin, 45-48 parts of white carbon black, 3.5 parts of softening oil, 3-3.2 parts of coupler, 5.2-5.8 parts of activator, 1 part of zinc stearate, 1 part of antifog agent, 1.9-2.1 parts of sulphur, and 1.65-1.95 part of accelerating agent, an ideal raw material functional combination can be obtained after applying the rubber formulation for sports shoes, which makes the sport shoe rubber sole having superwear resistance which is superior to the ordinary rubber sole, and has excellent properties such as wet-skid resistance, shock resistance and the like.

Description

technical field [0001] The invention relates to a rubber formula, in particular to a rubber formula for sports shoe soles. Background technique [0002] Due to its special purpose, sports shoes require that the rubber used for the sole should be wear-resistant, wet-slip resistant, and also have good impact resistance. However, in the current rubber technology for sports shoes, due to the irrationality of the formula, many Disadvantages: In the process of repeated bouncing and running, the soles of sports shoes wear out quickly, lose their elasticity, and slip. Contents of the invention [0003] In view of the above shortcomings, the present invention provides a super wear-resistant rubber formula for sports shoe soles with excellent wear resistance, wet skid resistance and good impact resistance. [0004] To achieve the above object, the technical solution of the present invention is: [0005] The formula of super wear-resistant rubber for sports shoe soles is characteri...
