Abstract

The invention discloses thermoplastic elastomer composition and resin as well as a preparation method and an application of the thermoplastic elastomer composition and resin in manufacturing of runways and courts. The thermoplastic elastomer composition is prepared from, in percentage by mass, 20%-40% of SEBS (styrene-ethylene-butylene-styrene) resin, 20%-50% of white oil, 10%-30% of polypropylene, 10%-30% of filler, 0.2%-1% of a lubricant, 0.3%-0.6% of an anti-oxidant auxiliary, 0.2%-0.4% of an anti-aging auxiliary, 0.05%-0.2% of a crosslinking agent and 0.2%-2% of a wear-resistant auxiliary, wherein the mass percentages of all the components add up to 100%. The thermoplastic elastomer resin is prepared from the thermoplastic elastomer composition. The thermoplastic elastomer composition and resin are used for preparing outdoor runways and courts and can improve the wear resistance and the weather resistance of outdoor sport fields such as the runways, the courts and the like in the use process.

Description

technical field [0001] The invention relates to the technical field of polymer materials and their processing, in particular to a thermoplastic elastomer composition, resin and its preparation method and its application in track and court. Background technique [0002] The plastic track is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. [0003] The commonly used composition material for plastic track or court is thermoplastic elastomer (TPE) based on styrene-ethylene / butylene-styrene block copolymer (SEBS), which is a kind of rubber wi...
