Composite wear-resisting shoe sole

Abstract

A composite wear-resisting shoe sole is prepared from, by weight, 60-100 parts of natural rubber, 10-50 parts of styrene butadiene rubber, 5-20 parts of polar rubber, 10-60 parts of modified white carbon black, 1-10 parts of zinc oxide, 1-4 parts of accelerant, 0.1-0.5 part of antioxidant, 2.5-4.5 parts of active agent, 5-20 parts of filler and 1-10 parts of sulfur .The filler is tetrapod-like zinc oxide whiskers .According to the composite wear-resisting shoe sole, the natural rubber and a small amount of polar rubber are jointly used as main rubber materials, the white carbon black subjected to toluene diisocyanate graft modification is added to serve as a reinforcing material, the tetrapod-like zinc oxide whiskers of a highly regular structure are used as a filling frame, the accelerant, the composite antioxidant and the active agent are added in sequence, and the composite wear-resisting shoe sole with high slippery resistance and tear strength and a remarkably improved frictional coefficient is prepared.

Description

technical field [0001] The invention relates to the technical field of shoe sole materials, in particular to a composite material wear-resistant shoe sole. Background technique [0002] In today's society, the improvement of living standards has made outdoor exercise and long-distance walking gradually become one of the popular ways to keep fit. However, the safety and comfort of sports have put forward strict requirements for the materials used to prepare shoe soles. With high elasticity, it needs to be wear-resistant and non-slip and suitable for large-scale processing and manufacturing, so as to meet the walking needs in complex and changing environments. [0003] Among the many characteristics, the wear resistance of the sole has received special attention. The existing test data show that in the state of use, the average pressure generated by the sole contacting the human foot and the sole against the ground is 0.4-0.7Mpa, while some individual parts of the footsteps T...

Problems solved by technology

[0004] At present, the soles of sports or mountaineering shoes are mostly made of foamed rubber as raw materials. The Chinese patent application publication number CN102863663A discloses high wear-resistant foamed rubber shoes. The raw materials of the soles are proportioned by weight: 50-70 parts of natural rubber; 80-90 parts of styrene-butadiene rubber; 5-10 parts of stearic acid; 10-20 parts of pigment; 30-50 parts of filler; 5-10 parts of foaming agent; 2-3 parts of foaming aid; 2 parts of plasticizer -5 parts, the preparation principle of this kind of sole material is simple, the production cost is low, and the overall quality is light. , hardness and resilience are extremely limited, elongation at break and coefficient of friction in a dry state are not ideal, and it is difficult to meet the needs of use in complex environments
