Abstract

The invention provides a thermoplastic elastomer material for an artificial lawn and a preparation method thereof. The material can meet environment-friendly requirements and simultaneously ensure the good performances of the artificial lawn, and the material can further improve the resilience of the artificial lawn and is environment-friendly. The material comprises the following components in parts by weight: 10-30 parts of styrene type thermoplastic elastomer, 1-5 parts of PP (polypropylene) or PE (polyethylene) or a mixture with the weight ratio of PP / PE of (0.5-3):1, 2-10 parts of novel metallocene-catalyzed propylene-ethylene copolymer, 5-20 parts of mineral oil, 4-10 parts of stearic acid, 20-200 parts of active calcium carbonate, 0.1-2 parts of antioxidant, 0.1-2 parts of anti-ultraviolet agent and 0.1-5 parts of pigment.

Description

[0001] Technical field: [0002] The invention belongs to the field of thermoplastic elastomers, and particularly designs a thermoplastic elastomer material for artificial turf and a preparation method thereof. [0003] Background technique: [0004] In recent years, artificial turf has replaced natural turf on sports grounds with good performance and environmental friendliness. As an integral part of the lawn system, artificial turf filling particles play an important role in the shock absorption, buffering and compaction of the lawn. [0005] In the past, the filling granules have been mainly recycled tire granules. With the introduction of European environmental protection directives, they have been banned because they do not meet environmental protection requirements, and the color is monotonous. The site temperature is too high in summer and dust is easy to appear. [0006] In patent document (1), publication number CN 101581068 A discloses a method for designing three...
