All-plastic plastic runway

Abstract

The invention discloses a full polyurethane type all-weather running track, which relates to the technology field of all-weather running track. The full polyurethane type all-weather running track comprises a base layer and a surface layer, wherein the surface layer is sprayed on the surface of the base layer. The proportioning of materials for laying the base layer of one square meter running track comprises 0.2 kg of base coatings, 2.5 kg of environment-friendly glues and 12.5 kg of EPDM particles. The base layer is 10 mm thick by the use of mechanical spreading. The proportioning of materials for laying the surface layer of one square meter running track comprises 0.5 kg of polyurethane pigment paste, 1.5 kg of EPDM particles and 1.5 kg of environment-friendly glues. The polyurethane pigment paste, the EPDM particles and the environment-friendly glues are mixed uniformly in proportion to be sprayed on the surface layer by the use of mechanical spraying and to be sprayed for three times in a forward direction, a reverse direction and a forward direction; each time the surface layer is sprayed with thickness being 1.0 mm, and the thickness of the surface layer is 3 mm. The full polyurethane type all-weather running track has the advantages of ultraviolet resistance, strong light exposure resistance, color fastness, excellent performance of nail resistance, wear resistance, compression resistance and durability, longer service life, short construction period and less manpower.

Description

technical field [0001] The invention relates to the technical field of plastic runways, in particular to all-plastic plastic runways. Background technique [0002] The plastic runway is also called the all-weather track and field track. It is composed of polyurethane rubber and other materials, and has certain elasticity and color. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is beneficial to athletes' speed. With the use of technology and technology, it can effectively improve sports performance and reduce the rate of falls. It is internationally recognized as the best all-weather outdoor sports ground material. The plastic track in the prior art generally has the following problems: [0003] (1) Since the plastic track is mostly set up outdoors, it needs to be exposed to sunlight for a long time, and under the sunlight and ultraviolet rays, the plastic particl...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the plastic track is mostly set up outdoors, it needs to be exposed to sunlight for a long time, and under the sunlight and ultraviolet rays, the plastic particles in the prior art are prone to fading and aging. Easy to layer cracking, short service life

[0004] (2) The construction period of the runway is long and the labor intensity of the workers is high

[0005] (3) The color of the upper and lower layers of the runway is inconsistent. If the surface layer is worn out, it will not only be unsightly, but also affect the performance

[0006] (4) Poor nail resistance, wear resistance, and compression resistance, especially in the frequently used 100-meter starting point or the heavy pressure area of ​​track and field equipment
