Abstract

The invention provides coated cork particles and a preparation method thereof. The coated cork particles are applied to artificial turf. The coated cork particles comprise cork particles, an EVA polymer emulsion and an EVOH film, wherein the EVA polymer emulsion is coated on the surface of the cork, and the EVOH film is used for wrapping the cork coated with the EVA emulsion. According to the invention, the cork which is natural renewable filling particles is adopted to replace traditional quartz sand and rubber particles; and the cork particles, the EVA polymer emulsion and the EVOH film supplement each other and complement each other in advantages, so that the prepared coated cork particles have good wear resistance and resilience, and also have renewable and reusable effects.

Description

technical field [0001] The invention relates to the technical field of artificial turf, in particular to a coated cork particle and a preparation method thereof. Background technique [0002] With the development of the market, great changes have taken place in artificial grass in terms of materials, technology, construction, etc. The purpose of these changes is to make artificial grass closer to natural grass in sports performance. At present, the artificial turf of most sports fields is generally made of PE material, filled with quartz sand, and filled with rubber particles at the same time, so that it has the elasticity of natural grass. However, due to the problems of easy aging and pulverization of rubber particles, harmful gases and fine particles, the difficulty of recycling the entire lawn is greatly increased, which leads to health and environmental protection problems such as difficult degradation, difficult recycling, and unhealthy. Now many countries have banned...
