Abstract

The invention discloses a hollow thermoplastic rubber filling particle for artificial turf filling and a preparation method of the hollow thermoplastic rubber filling particle, wherein the hollow thermoplastic rubber filling particle is of a hollow tubular structure and prepared from the following components in parts by weight: 50-80 parts of high-viscosity basic resin, 20-40 parts of inorganic fillers, 0.1-5 parts of auxiliary and 0.1-10 parts of color master batches, wherein the auxiliary is a mixture formed by mixing an antiager with a coupling agent according to a weight ratio of (1-5):(1-5). The hollow thermoplastic rubber filling particle disclosed by the invention is formed by melting, blending, extruding and underwater granulating high-viscosity thermoplastic elastomers, and has the advantages of persistent elasticity, good water permeability, small packing density, low filling cost, recoverability and the like.

Description

technical field [0001] The invention relates to a thermoplastic rubber filling material, in particular to a hollow thermoplastic rubber filling particle for artificial turf filling and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of living standards, people have more and more sports needs, and various plastic runways, playgrounds and artificial turf have been built in large numbers. Among these artificial sports systems, artificial turf has excellent performance, low maintenance cost, no mosquitoes, is very little affected by the environment, weather, and region, and can be used in extreme climate areas such as high cold, high temperature and plateau, etc. Natural lawn is incomparable In recent years, its market has been growing at a rate of 20-25% every year, and its application has also broken through the traditional construction of stadiums, and has been widely used in various leisure fields, providing great ...
