Environment-friendly flame-retarding full-plastic type plastic runway and construction method thereof

Abstract

The invention provides an environment-friendly flame-retarding full-plastic type plastic runway. The environment-friendly flame-retarding full-plastic type plastic runway comprises a base layer, a bottom sealing layer, a shock absorption layer and a cover face protecting layer; the bottom sealing layer, the shock absorption layer and the cover face protecting layer are sequentially laid on the base layer, materials of the base layer are poured by adopting C30 commercial concrete, and the thickness of the base layer is 150 mm; the bottom sealing layer adopts materials of non-toxic environment-friendly single-component epoxy glue, black colloidal particles and silica sand, coating is conducted by adopting a coating machine, the thickness of the bottom sealing layer is 1.5 mm; the shock absorption layer adopts EPDM, SBR, CR, NR mixed rubber particles and the environment-friendly single-component epoxy glue materials, mechanical spreading is conducted, the laying thickness is 10 mm; and the cover face protecting layer adopts materials of polyurethane color paste, EPDM particles, the environment-friendly single-component epoxy glue, glass fiber, an antioxidant, a flame retardant and a fluorescent agent, mechanical coating is conducted, coating is conducted for three times in the forward direction, the reverse direction and the forward direction, the thickness of each time of coatingis 1 mm, and the thickness of the cover face protecting layer is 3 mm. The environment-friendly flame-retarding full-plastic type plastic runway has the advantages that non-toxic, odourless and environment-friendly effects are achieved, the runway is breathable, water does not accumulate on the surface of the runway, color is bright, and color fading is not likely to occur, and meanwhile, uvioresistant and strong light exposure resistance performance are achieved, bubbling and cracking are not likely to occur, the abrasion performance, compression resistance and durable performance are excellent, and the service life is long; and in addition, the runway is high in cost performance, low in input cost and good in weather-resistant performance and is suitable for using and popularizing in anational scale.

Description

technical field [0001] The invention relates to the technical field of plastic runway construction, in particular to an environment-friendly flame-retardant all-plastic plastic runway and a construction method thereof. Background technique [0002] The plastic runway is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, EPDM rubber particles, pigments, additives, fillers, etc. The plastic runway has good flatness, high compressive strength, appropriate hardness and elasticity and physical The characteristics of stable performance are conducive to the performance of athletes' speed and technology, effectively improving sports performance and reducing the rate of falls. It is internationally recognized as the best all-weather outdoor sports floor material. At present, the common plastic track is generally paved on-site with SBR rubber particles, EPDM rubber particles, polyurethane glue and other auxiliary materials. ...
