Novel plastic environment-friendly breathable runway

Abstract

The invention discloses a novel plastic environment-friendly breathable runway. The runway comprises a first component material and a second component material, wherein the first component material covers the second component material; wherein the mass ratio of the first component material to the second component material is 1: 1; wherein the first component material is prepared from the followingcomponents in parts by weight: 35 to 40 parts of polyurethane resin, 8 to 12 parts of mixture particles prepared by mixing styrene butadiene rubber, high styrene resin and syndiotactic polystyrene, 40 to 50 parts of EPDM particles, 3 to 8 parts of filler, 1 to 2 parts of pigment, 0.5 to 1 part of anti-aging agent and 0.5 to 1 part of flame retardant; wherein the particle size of the EPDM particles of the first component material is 1-2 mm; the second component material comprises the following components in parts by weight: 45-50 parts of a mixture of polyurethane resin and epoxy resin; 40 to50 parts of EPDM particles, 3 to 8 parts of a filling material, 1 to 2 parts of a pigment, 0.5 to 1 part of an anti-aging agent and 0.5 to 1 part of a flame retardant; and the particle size of the EPDM particles of the second component material is 3-5mm. The novel plastic environment-friendly breathable runway has the beneficial effects that the novel plastic environment-friendly breathable runwayhas better breathability, coating adhesiveness and compressive strength.

Description

technical field [0001] The invention relates to a novel plastic environment-friendly and air-permeable runway, in particular to an environment-friendly and air-permeable surface layer material for the plastic runway. 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-we...

Problems solved by technology

[0003] The traditional plastic track surface material has poor air permeability

Under high temperature conditions, the foundation will generate water vapor. Due to the insufficient air permeability of the surface layer of the plastic runway, the water vapor cannot pass through the surface layer and finally bulges the surface layer, which shortens the service life of the plastic runway.

In addition, the traditional plastic runway surface material has poor adhesion to paint, and the drawn lines on the runway are easy to detach
