Abstract

The invention discloses a waterproof and breathable plastic track material. The waterproof and breathable plastic track material comprises a base layer made of asphalt materials, a buffering layer made of polyurethane resin and EPDM particles, a bonding layer made of a polyurethane bonding agent and a polyurethane face layer made of double-component materials composed of a component A and a component B. The base layer made of the asphalt materials, the buffering layer made of the polyurethane resin and the EPDM particles, the bonding layer made of the polyurethane bonding agent and the polyurethane face layer made of the double-component materials composed of the component A and the component B are sequentially stacked from bottom to top to form a waterproof and breathable plastic track. The plastic track prepared through the plastic track material is good in water prevention performance and breathability, the quality of the plastic track is improved, and the service life of the plastic track is prolonged; and the preparing method is simple, and convenience is brought to users.

Description

technical field [0001] The invention relates to the related fields of plastic runways, in particular to a waterproof and breathable plastic runway material and a preparation method thereof. Background technique [0002] The plastic track is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. 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. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather outdoor sports floor ...
