High-wear-resistance transparent TPU spherical film and preparation method thereof

Abstract

The invention provides a high-wear-resistance transparent TPU spherical film and a preparation method thereof. The high-wear-resistance transparent TPU spherical film is prepared by mixing and tape-casting the following components in parts by weight: 60-90 parts of polyurethane-nanopowder complexing agent, 2-10 parts of chain extender, 0.3-2 parts of antioxidant, 1-4 parts of hydrolysis stabilizer, 0.8-3 parts of slipping agent, 0.8-3 parts of antiblocking agent, 1-10 parts of filling agent and 1-3 parts of flame retardant. The TPU spherical film material prepared by modifying and creating all components and preparation proportion of the TPU spherical film has unique technological advantages of being high in wear resistance, transparency and hydrolysis resistance properties, good in elasticity, cold-proof, durable, environment-friendly in materials, free from any hidden injury to a human body, printable, and capable of performing high-frequency welding and the like, the wide use of the TPU special film material in a plurality of fields can be promoted, and the TPU spherical film material has wide market prospects.

Description

technical field [0001] The invention relates to TPU material technology, and more specifically relates to a high wear-resistant transparent TPU spherical film and a preparation method thereof. Background technique [0002] TPU (Thermoplastic polyurethanes) material is a kind of thermoplastic polyurethane elastomer material, which has the advantages of wide hardness range, wear resistance and oil resistance, transparency and good elasticity, so it is widely used in daily necessities, sporting goods, toys, decorative materials and other fields, and has Gradually replace PVC to meet the trend of environmental protection requirements in more and more fields. Traditional football membranes are mostly made of leather and stitched with traditional needles, but because each seam usually forms localized hardening inside the shell, players cannot effectively control or kick the ball Can not follow the exact flight path, in addition, the traditional leather has poor wear resistance an...

AI Technical Summary

Problems solved by technology

Traditional football membranes are mostly made of leather and stitched with traditional needles, but because each seam usually forms localized hardening inside the shell, players cannot effectively control or kick the ball Can not follow the accurate flight path, in addition, the traditional leather has poor wear resistance and is prone to hydrolysis and other problems during use, so the traditional spherical film preparation leather has serious defects

Although TPU material is a material with broad market prospects, the existing TPU materials generally have defects such as insufficient hardness, poor wear resistance, insufficient elasticity and toughness when applied to spherical membranes, especially football membranes, which limit the use of TPU in football membranes. Wide application on the Internet, which in turn limits the development of high-quality ball sports equipment
