Comfortable and wear-resistant rubber shoe sole and preparation method thereof

Abstract

The invention relates to a comfortable and wear-resistant rubber shoe sole and a preparation method thereof. The comfortable and wear-resistant rubber shoe sole comprises 55-65 parts of natural rubber, 25-35 parts of styrene butadiene rubber, 10-15 parts of cis-butadiene rubber, 50-58 parts of carbon black, 8-12 parts of aluminum silicate, 5-10 parts of polyurethane, 1.8-2 parts of sulfur, 1.5-3 parts of an accelerant, 6-7 parts of a vulcanization activator, 15-21 parts of a rubber softening agent, and 2.3-3.8 parts of an anti-aging agent. Compared with the existing rubber shoe sole, the comfortable and wear-resistant rubber shoe sole has good wear resistance, as well as great comfort, environmental friendliness and safety.

Description

technical field [0001] The invention relates to the technical field of rubber soles, in particular to a comfortable and wear-resistant rubber sole and a preparation method thereof. Background technique [0002] Footwear is of a great variety at present, wherein the footwear that uses rubber sole accounts for more than 90% in footwear wherein. In recent years, with the continuous improvement of daily life standards, people come into contact with more and more shoes of various styles and functions. Among them, the changes brought about by the sole material are the basis for the changes in the functions of shoes. Changes in the structure of the sole and upper require a variety of materials or a single or reasonable combination of each other, in order to achieve the best comfort, hygiene, wear resistance and safety requirements of the shoes. The reasons affecting the wear resistance of the outsole of rubber shoes mainly include three factors: rubber formula design, rubber proce...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the use of plastic components in the rubber can reduce the frictional resistance between the product and the ground and improve the wear resistance, but the use of plastic components will reduce the wet skid resistance of the rubber product, and the product’s ability to guarantee personal safety Therefore, it is unreasonable to use plastic components in the rubber compound to improve the wear resistance of rubber

It is also possible to increase the amount of synthetic rubber in the compound formula. With the increase of the amount of synthetic rubber, the wear resistance of rubber will be improved, but because the molecular weight distribution of synthetic rubber is narrow and the uniformity of larger molecules is stronger , and synthetic rubber has a certain semi-plastic nature, when its amount is greater than a certain proportion, the gripping ability of rubber products will be reduced, and the safety of the human body in high-speed actions will also be affected

In terms of the Shore hardness of vulcanized rubber, when the Shore hardness is higher, it is beneficial to improve the wear resistance of the rubber, but at the same time the wearing comfort of the shoe will be reduced
