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

preparation example Construction

[0047] The preparation method of described amino-terminated hyperbranched polyamide-amine can be:

[0048]Add 1~2mol of N-aminoethylpiperazine and 1~4mol of bisacrylamide monomer into 30ml methanol aqueous solution, stir and react at 70~80°C for 80~90h, cool down naturally, wash with deionized dilution, and then The end-capped hyperbranched polymer is precipitated with cold acetone, and vacuum-dried at room temperature for 10-24 hours to obtain amino-terminated hyperbranched polyamide-amine.

[0049] In one embodiment, the preparation method of the glyoxal modified chitosan-amino-terminated hyperbranched polyamide-amine complex is as follows: in a 100ml three-necked bottle, add the above-mentioned synthetic glyoxal modified shell 0.1 g of polysaccharide, 0.2-2 g of amino-terminated hyperbranched polyamido-amine, and 50 ml of N,N-dimethylformamide, after stirring at room temperature; after reacting at 50-80°C for 10-24 hours, Settling and filtering in medium to obtain glyoxal ...

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...
