Abstract

The invention discloses a preparation method of plastic particles for a plastic track. The preparation is characterized by comprising the following specific production steps: (1) mixing a pigment, an additive, sulfuric acid and EPDM rubber according to proportion; (2) carrying out material feeding, that is, feeding the mixed materials as well as rubber oil and calcium carbonate into a mixing mill; (3) mixing through the mixing mill; (4) plasticizing through an open mill; (5) carrying out dicing processing; (6) sulfidizing; (7) slicing; (8) granulating through a granulator; (9) screening and classifying, that is, packaging the plastic particles which meet the particle size requirements for storage; (10) putting the plastic particles which does not meet the particle size requirements into the granulator for granulation again. The preparation method provided by the invention has the characteristics of being simple in technology and high in production efficiency; moreover, the plastic particles produced according to the preparation method has the characteristics of being long in service life and low in falling-off possibility.

Description

Technical field: [0001] The invention relates to the technical field of plastic runway production technology, in particular to a method for preparing plastic granules for a plastic runway. Background technique: [0002] The plastic track is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather outdoor sports floor ...
