High-antibacterial-performance and high-wear-resistance TPE (thermal plastic elastomers) shock-absorption kneecap and preparation method thereof

Abstract

A high-antibacterial-performance and high-wear-resistance TPE (thermal plastic elastomers) shock-absorption kneecap is prepared from the following raw materials in part by weight: 100 parts of MAH-g-SEBS, 40-50 parts of MAH-g-PP, 5-15 parts of glyoxal modified chitosan-amino-terminated hyperbranched polyamide-amine complexes, 1-5 parts of chitosan-beta cyclodextrin modified nanometer tio2 and 0.5-2 parts of zirconia ceramic microbeads. The TPE shock-absorption kneecap is excellent in shock absorbing property, high in strength, high in wear resistance and high in antibacterial performance, and a user feels comfortable when using the kneecap.

Description

technical field [0001] The invention belongs to the field of shock-absorbing knee pads. More specifically, the invention relates to a shock-absorbing knee pad with TPE as the main raw material and a preparation method thereof. Background technique [0002] The knee is an extremely important part of people's exercise process, and it is also a relatively fragile and easily injured part. Traditional knee pads are mainly composed of high-elastic textile fabrics, which can protect the knees to a certain extent due to their special texture and materials, but for athletes who often do intense sports, this type of knee pads cannot meet their higher protection needs. Shock-absorbing knee pads made of EVA and PU materials on the market have better shock resistance than the above-mentioned traditional knee pads, but EVA knee pads have poor permanent deformation, poor wear resistance, and high resilience, and the vulcanization process during preparation will cause them to produce har...

AI Technical Summary

Problems solved by technology

Traditional knee pads are mainly composed of high-elastic textile fabrics, which can protect the knees to a certain extent due to their special texture and materials, but for athletes who often do intense sports, this type of knee pads cannot meet their higher protection needs

Shock-absorbing knee pads made of EVA and PU materials on the market have better shock resistance than the above-mentioned traditional knee pads, but EVA knee pads have poor permanent deformation, poor wear resistance, and high resilience, and the vulcanization process during preparation will cause them to produce harmful odor, while PU knee pads have the disadvantages of easy yellowing, easy hydrolysis, and high specific gravity

In addition, the knee pads used during exercise will inevitably come into contact with the sweat from the human body. Improper cleaning or storage can easily breed bacteria and mold, and directly damage the skin that touches the knee pads, and even cause uncomfortable skin diseases. The above-mentioned EVA and PU knee pads often do not have antibacterial function
