Abstract

The invention discloses a high-elastic plastic runway and a construction method thereof. The high-elastic plastic runway sequentially comprises a base layer, a waterproof bonding layer, an elastic layer, a bonding layer and a surface layer from bottom to top, wherein the base layer is a cement base layer or an asphalt base layer; the waterproof bonding layer is a water-borne epoxy resin layer; theelastic layer is a mixture of a foamed polyurethane material and EPDM particles, and the mass ratio of the foamed polyurethane material to the EPDM particles is 1:(0.5-2); the bonding layer is made of a polyurethane adhesive; the surface layer is a mixture of a polyurethane adhesive and EPDM particles, and the mass ratio of the polyurethane adhesive to the EPDM particles is 1:(5-6). The high-elastic plastic runway is good in mechanical property, excellent in buffering and damping effect, resistant to aging, non-toxic, environmentally friendly and capable of being widely applied to indoor places such as kindergartens.

Description

technical field [0001] The invention relates to the technical field of plastic runways, in particular to a high-elasticity plastic runway and a construction method thereof. Background technique [0002] The plastic track is generally composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives and fillers, which have good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. characteristics. However, when athletes exercise on the plastic track, they will also exert a certain impact force on the plastic track. If the plastic track is not elastic enough, it will cause a greater counter-impact to the athlete, and it is easy for the athlete to be injured; Thickening the thickness of the plastic runway to improve the elasticity of the plastic runway will easily cause partial depression of the plastic runway, which will affect the service life of the plastic ...
