Abstract

The invention relates to an environment-friendly thermoplastic elastomer particle for filling an artificial turf and a preparation method of the thermoplastic elastomer particle. The preparation materials of the thermoplastic elastomer particle comprise the following various components by the total mass of the various components: (A) 30%-70% of a thermoplastic material, (B) 0-25% of mineral oil, (C) 10%-40% of thermoplastic polyurethane elastomer, (D) 10%-50% of inorganic filler, (E) 0.1%-3% of UV-resistant aid, and (F) 0.5%-6% of color master batch or toner. The various components are melted and blended at a certain proportion to obtain a composition aggregate, the thermoplastic elastomer particle can be recycled, is environment-friendly and pollution-free and is colorful, the rebound resilience and the abrasion resistance are obviously improved, the particle is convenient to produce, the form of the particle can be regulated and controlled, and the packing density is low.

Description

technical field [0001] The invention relates to an environment-friendly artificial turf filling thermoplastic elastomer granule and a preparation method thereof, in particular to a thermoplastic polyurethane elastomer-containing high-resilience thermoplastic elastomer granule and a preparation method thereof, belonging to the field of polymer material research. Background technique [0002] Artificial turf is widely used in the fields of sports and landscaping. Because of its incomparable advantages such as excellent mechanical properties, low maintenance cost, and little influence from the environment, weather and region, its market has grown by more than 20% every year in recent years. rate increase. [0003] Artificial turf generally consists of four layers: grass fiber, filling layer, backing and foundation. The filling layer is currently mainly rubber filling particles, and its main function is: on the one hand, it can keep the grass upright; on the other hand, it can ...
