AI Technical Summary

Problems solved by technology

The existing plastic runway will experience performance degradation, partial damage, and reduced stability after being used for a period of time
[0003] In addition, as the market has higher and higher requirements for the environmental protection performance of sports floor materials, ordinary silicon PU materials have a certain degree of volatility.
Especially under the sun exposure and high temperature, it is prone to the problem of continuous volatilization of harmful gases, which seriously affects human health

Abstract

The invention relates to the technical field of materials and material use and a laying preparation method of a sports field, in particular to a water-based silicon PU adhesive and a laying method ofa water-based silicon PU adhesive sport field. Multilayer treatment is adopted, base layer construction is realized, cut seams are added, use in regions with more rainwater, dryness and changeable temperatures is guaranteed effectively, a base layer is firmer and more reliable and can prevent cracking of an upper coating, and the overall stability can be substantially improved. Multilayer roll coating is performed on a new formula of the water-based silicon PU adhesive, and performance of the sports field is further optimized by an elastic layer and a reinforcement layer. A surface layer is formed by the new formula of water-based silicon PU adhesive and quartz sand, and the performance is durable and stable on the premise that the surface layer is environmentally friendly, safe and brightin color.

Description

technical field [0001] The invention relates to the technical field of materials, and relates to the use of materials and a preparation method for laying a sports field. Specifically, it is a water-based silicone PU glue and a method for laying a sports field. Background technique [0002] The plastic track is also known as the all-weather track and field track. The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is also beneficial to reduce the injury rate of athletes and protect the safety of athletes. After a period of use, the existing plastic track will have performance degradation, partial damage, and reduced stability. [0003] In addition, as the market has higher and higher requirements for the environmental performance of sports floor materials, ordinary silicon PU materials have certain volatility. In particular, the problem of continuous volatilization of...
