Problems solved by technology

For a long time, Tianpi has always been fond of polyurethane materials with high hardness. The Shore hardness of the product is above 95A, even as high as 70D. However, the product is inelastic, which will cause the wearer to strain the back muscles and hurt the feet; the sound is very loud when walking , which brings embarrassment in quiet office places; polyurethane is physically cross-linked, and its wear resistance is average. After wear, it is easy to produce burrs, which affects the appearance

Abstract

The invention relates to the technical field of organic macromolecular compounds and provides a noiseless comfortable rubber heel lift and a preparation method thereof. The noiseless comfortable rubber heel lift comprises natural rubber, butadiene styrene rubber, butadiene-acrylonitrile rubber, high-styrene rubber, rubber powder, white carbon black, mineral oil, anti-aging agent, polyethylene glycol, silane coupling agent, zinc oxide, sulphur and vulcanization accelerating agent. The noiseless comfortable rubber heel lift has the advantages that the heel lift is elastic and noiseless, pressure and discomfort borne by the foot can be reduced, wearing comfort is improved, the trouble of noise is got rid of, and high wear-resisting and anti-slip performance and long service life are achieved.

Description

technical field [0001] The invention belongs to the technical field of organic polymer compounds, in particular to a quiet and comfortable rubber top and a preparation method thereof. Background technique [0002] The aesthetic concept of modern people is that a slender body is beautiful. After wearing high-heeled shoes, the body forms a posture of raising the head, chest and abdomen, looking tall, straight and graceful, which enhances the feeling of beauty. High-heeled shoes are very popular, enhancing beauty and improving self-confidence, but pains such as back muscle strain, knee arthritis, and ankle sprains also follow one after another. Women who love high-heeled shoes need to endure these ailments for a long time, and they have not been effectively solved. The design of the waterproof platform, heel height, heel slope, outsole, and top skin of high-heeled shoes are all very important. Among them, the material design of the top skin is particularly important. Usually,...
