Plastic surface layer of elastic bead track for athletic running

Abstract

The invention relates to a surface layer material of an athletic field, and aims to provide a plastic surface layer of an elastic bead track for athletic running. The plastic surface layer has the characteristics of good friction performance, excellent impact and absorption property, firm structure, excellent durability, water permeability and air permeability. According to the technical scheme, the plastic surface layer of the elastic bead track for athletic running comprises a plurality of near-spherical macromolecular elastic body beads, and is characterized in that the near-spherical macromolecular elastic body beads are piled up to form the plastic surface layer with a certain thickness, the adjacent elastic body beads are connected one another integrally through adhesives of portionswhich are in contact with one another, or the portions which are in contact with one another are fused and adhered integrally; and the other portions form irregular hollowed-out gaps.

Description

technical field [0001] The invention relates to a sports field surface material, especially the plastic surface layer of track and field track and fitness trail, which can also be used in various ball games and multifunctional sports fields. Background technique [0002] The plastic surface layer of the track and field track is usually composed of a polymer material elastic base layer and a polymer material elastic particle surface layer. Among them, the elastic particle surface layer is to provide a suitable friction coefficient for the track to improve sports performance and reduce the risk of athletes slipping. [0003] The existing track and field runway plastic surface layer is the following five types: (1) prefabricated rubber runway surface layer; [0004] (2) Hybrid plastic runway surface; (3) Composite plastic runway surface; (4) All-plastic plastic runway surface; (5) Breathable plastic runway surface. However, the above-mentioned types of runway surfaces all or ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned types of runway surfaces all or partly have the following disadvantages: (1) The requirements for the foundation of the site are extremely high, and a little carelessness will cause quality problems such as cracking, foaming, bulging, and water accumulation on the plastic surface (2) The construction process is complicated, the construction period is long, and the labor cost is high; (3) Except for the surface layer of the prefabricated rubber runway, other runways need to be sprayed and scraped, and the environmental pollution is serious; (4) Except for the prefabricated rubber runway In addition to the surface layer, other runway surface layers need to be formed by mixing and reacting two-component polyurethane prepolymers on site. Factors such as weather conditions, temperature levels, air moisture content, material measurement accuracy, and whether construction personnel operate in strict accordance with the standard process are directly related. Affect the quality and environmental performance of the runway surface; (5) Except for the prefabricated rubber runway surface, the anti-skid particles on the surface of other runway surfaces are easy to break and fall off
