Problems solved by technology

[0003] At present, rubber granules for artificial turf at home and abroad, especially black waste tire granules, are mainly used in China. Although the cost of waste tire granules is low, and can alleviate the problems of rubber resource shortage and waste tire environmental pollution, however, Tire granules also have disadvantages such as inferior tire raw materials, strong smell, single color, and cannot be recycled and reused.

Abstract

The invention provides a preparation method of artificial lawn particles. The formula of the lawn particles comprises the following components: 100 parts of raw rubber, 20-150 parts of filler, 0-20 parts of a plasticizer, 0-6 parts of an active agent, 1-5 parts of an anti-ageing agent, 0-5 parts of a vulcanizing agent, 0-6 parts of an accelerant and 1-8 parts of a coloring agent. The preparation method comprises the following production steps: (1) adding rubber compounds into an internal mixer according to a ratio, sequentially adding the filler, plasticizer, anti-ageing agent, vulcanizing agent and the like, mixing and uniformly discharging, and batching-off so as to obtain a rubber master batch; (2) placing the rubber master batch on an open mill, uniformly mixing, and batching-off sheets; and (3) extruding the sheets in an extruder to form strips, granulating after cross-linking, or performing extrusion granulation and cross-linking. The lawn particles provided by the invention arelightweight, high in strength, environmentally friendly and excellent in ageing resistance. Moreover, the particles have the characteristics of being difficult to discolor and long in service life.

Description

technical field [0001] The invention belongs to the field of polymer materials, and more specifically relates to a formula and a preparation method of aging-resistant and environment-friendly plastic particles filled in artificial turf. Background technique [0002] Artificial turf is a artificial lawn made of non-living plastic chemical fiber products. Unlike natural turf, it does not need to consume resources such as fertilizers and water necessary for growth. It can meet the needs of high-intensity sports 24 hours a day, and has simple maintenance, rapid drainage, and excellent site flatness. Artificial turf has the advantages of bright appearance, green seasons, vividness, good drainage, long service life, and low maintenance costs. Artificial turf is widely used in special venues for hockey, baseball, and rugby, public practice fields for sports such as football, tennis, and golf, or as ground pavement to beautify the indoor environment. The rubber particles are locat...
