Environment-friendly plastic granules specially used for sport venue and preparation method of plastic granules

Abstract

The invention relates to environment-friendly plastic granules specially used for a sport venue. The plastic granules are prepared from the following raw materials in parts by weight: 20-40 parts of high-density polyethylene, 60-80 parts of ethylene propylene terpolymer, 100-300 parts of light calcium carboante, 1-3 parts of 2,5-dimethyl-2,5-dihexane, 0.2-0.5 part of polyethylene wax, 0.2-0.5 part of stearic acid, 0.5-1.5 parts of trialkenyl methyl triisocyanurate and 5-15 parts of liquid paraffin. The invention also discloses a preparation method of the environment-friendly plastic granules specially used for the sport venue. The environment-friendly plastic granule product has unique toughness, flexing resistance, impact resistance and elasticity. The environment-friendly plastic granules can be widely used for industrial and civilian facilities, including family courtyards, gymnasia, leisure roads, paving materials, fitness and sports venues and ship deck surfaces. According to the invention, an efficient environment-friendly vulcanization system is adopted, sulfur-free vulcanization is achieved, and sulfuric acid and the like are not generated so as to avoid the environmental pollution; the weather resistance and production effect of the material are greatly improved.

Description

technical field [0001] The invention relates to a plastic material and a preparation method thereof, in particular to an environment-friendly special plastic particle for sports venues and a preparation method thereof. Background technique [0002] Tennis courts, basketball courts, badminton courts, volleyball courts, children's playgrounds and other sports venues or playgrounds are mostly paved with plastic granule materials. Since the plastic granule material can be used all-weather after paving the field, it can improve the utilization rate of the field, has moderate elasticity and rebound force, moderately absorbs the impact force of the foot, and also has wear resistance, compression resistance, impact resistance, flatness, Security and many other superior properties are more and more widely used. [0003] At present, the following problems generally exist in the special plastic products for sports venues on the market: the product quality is difficult to meet the deve...

Problems solved by technology

[0003] At present, the following problems generally exist in the special plastic products for sports venues on the market: the product quality is difficult to meet the development requirements of the modern era; the traditional vulcanization formula and molding vulcanization process are used, and the molding method requires a lot of labor, consumes a lot of energy, and has low production capacity; The existence of sulfur residues, under harsh weather conditions, various physical properties will decline, especially the phenomenon of discoloration; sulfuric acid will be produced under ultraviolet light, causing secondary pollution to the environment, failing to meet environmental protection requirements
