Problems solved by technology

In the past, the polyurethane plastic runway was transported to the project site for preparation, laying and pouring of liquid glue. Due to the limitation of natural weather and objective conditions, the plastic runway project for construction and laying not only failed to meet the uniform standard thickness, flatness and uniformity. and other defects, and because of the site pouring construction exudes a large amount of harmful odor causing environmental pollution, seriously affecting people's lives and the environment

Abstract

The invention relates to the technical field of a plastic track, in particular to a manufacturing process of a polyether polyurethaneurea prefabricated plastic track. The process is characterized inthat a product structure is divided into three layers: a surface layer, a strong power layer and an elastic layer. The raw materials comprise terminated isocyanate, polysiloxane, hydroxyl-terminated polybutadiene, polyurethane polyurethane adhesives, talcum powder, kaolin, lead salt, organic tin, phthalocyanine blue, red clay, stearate, phthalate, EPDM rubber particles and damping particles. The process has the advantages that the thickness of the laid track has uniform thickness; the appearance is attractive; durability is realized; the level and grade of the sports field are greatly improved;the construction speed is high; the harmful smell radiation and pollution due to volatile matters generated during the plastic slurry laying and injection in the prior art on the environment can be avoided; the social benefits and the life quality of people are greatly improved.

Description

technical field [0001] The invention relates to the technical field of plastic runways, in particular to a manufacturing process of polyurea polyurethane prefabricated plastic runways. Background technique [0002] The plastic track is also called 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 conducive to athletes' speed and technology, effectively improving sports performance and reducing the rate of falls , is internationally recognized as the best all-weather outdoor sports floor material. In the past, the polyurethane plastic runway was transported to the project site for preparation, laying and pouring of liquid glue. Due to the limitation of natural weather and objective conditions, the plastic runway project for construction and laying not only failed to meet the uniform standard thickness, flatness and uniformity. ...
