Problems solved by technology

[0003] In ball sports, especially in football, leg guards are essential protective gear. Football players sweat a lot, and their body temperature rises, so they need to cool down, and the collision of limbs, especially legs, during sports It is essential, so it is necessary to wear leg guards for protection, and most of the guards are bulky and affect the speed of athletes, so there is a need for a leg guard that is light in weight, high in hardness, and can reduce body temperature and quickly absorb sweat.

Abstract

The invention discloses a special novel material for a TPU leg guard plate, and a preparation method thereof. The material is prepared from 20-38 wt% of PEA-1800, 3-6 wt% of 1,4-BDO, 1 wt% of 1,3-BDO,24-38 wt% of MDI, 10-24 wt% of polymeric water-absorbent resin, 6-8 wt% of titanium oxide, 20-30 wt% of bamboo fibers, 0.2-0.4 wt% of an antioxidant and 6-8 wt% of a reinforcing agent. The material has the advantages of good transparency, convenience in coloring, rapidness in cooling and sweat absorption, antibacterial and self-cleaning functions, good wear resistance, high strength, high impactresistance, high toughness, suitableness for all kinds of bad weather, keeping of dryness, maintaining of the elegant appearance of the guard, improvement of the use effect of the product, and prolongation of the service life.

Description

technical field [0001] The invention relates to the field of sports equipment, more specifically, a new type of special material for TPU leg shields and a preparation method thereof. Background technique [0002] When the existing TPU production materials are applied to many fields, they often have strict requirements for their various performance indicators, especially high temperature resistance, wear resistance, hardness and toughness. [0003] In ball sports, especially in football, leg guards are essential protective gear. Football players sweat a lot, and their body temperature rises, so they need to cool down, and the collision of limbs, especially legs, during sports Therefore, it is necessary to wear leg guards for protection, and most of the guards are bulky and affect the speed of athletes. Therefore, there is a need for a leg guard that is light in weight, high in hardness, and can reduce body temperature and quickly absorb sweat. Contents of the invention [...
