Title: ELASTIC PARTICLE AND PREPARATION METHOD AND APPLICATION OF SAME
Abstract:
The present invention discloses an elastic particle, comprising the following components in parts by weight: 10 to 50 parts of a thermoplastic elastomer, 50 to 90 parts of a filler, and 0.1 to 10 parts of other additives. Also provided is a preparation method for the elastic particle, comprising: 1) weighing the components according to the formula, and evenly stirring the components in a high-speed mixer; and 2) producing particles by extrusion using a twin-screw extruder at an extrusion temperature of 110-250°C, a pelletizing method being water-ring die surface pelletizing, underwater die surface pelletizing, air-cooling die surface pelletizing, or strand pelletizing. The elastic particle is desirably elastic, wear-resistant, skid resistant, and durable. The application of the elastic particle is laying elastic particles in an artificial turf with a specific laying thickness, to achieve good shock-absorbing and skid resistance effects.
