Abstract

The invention discloses an environment-protecting water-based all-plastic track construction method. According to the technical scheme, the method is characterized by comprising the following steps ofS1, applying water-based all-plastic track adhesive and rubber powder to a construction base surface after uniformly mixing the water-based all-plastic track adhesive and the rubber powder accordingto the mass ratio of 1 to 1.2, and carrying out curing until drying to form an elastic layer; S2, applying the water-based all-plastic track adhesive and the rubber powder to the elastic layer after uniformly mixing the water-based all-plastic track adhesive and the rubber powder according to the mass ratio of 1 to 0.9, and carrying out curing until drying to form a levelling base layer; S3, applying the water-based all-plastic track adhesive and the rubber powder to the levelling base layer after uniformly mixing the water-based all-plastic track adhesive and the rubber powder according to the mass ratio of 1 to 0.8, and carrying out curing until drying to form a levelling surface layer; and S4, spraying water-based acrylic hybrid emulsion, a curing agent and the rubber powder to the levelling surface layer after uniformly mixing the water-based acrylic hybrid emulsion, the curing agent and the rubber powder according to the mass ratio of 100 to (4 - 6) to (25 - 35), and carrying outcuring until drying to form an anti-slip surface layer. According to the environment-protecting water-based all-plastic track construction method, the constructed water-based all-plastic track has theadvantages of being non-toxic, environment-protecting, good in resilience and not prone to crack. The invention further correspondingly discloses an environment-protecting water-based all-plastic track obtained by applying the method.

Description

technical field [0001] The invention relates to the technical field of plastic runway, more specifically, it relates to an environment-friendly water-based all-plastic runway construction method and an environment-friendly water-based all-plastic runway. Background technique [0002] The plastic runway is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, fillers, etc. 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. It is an internationally recognized outdoor sports venue. Ping material. [0003] But there are many negative reports about plastic track in real life. According to reports, the news that "toxic plastic track" appeared in many schools in a c...
