Problems solved by technology

[0003] Although silicon PU has good elasticity and certain wear resistance, and its various performances are superior to those of traditional cement or wooden floor courts, however, silicon PU is not resistant to wind, rain and sunlight. It is prone to hardening, stickiness, loss of strength, etc., which easily affects the service life of silicon PU. Therefore, there is still room for improvement

Abstract

The invention relates to the field of plastic field materials, and provides a silicon PU for a plastic field material aiming at the problem that the service life of silicon PU is affected due to the fact that silicon PU is prone to erosion by ultraviolet rays. Silicon PU is prepared from the following components in parts by mass: 200-280 parts of polyether polyol, 70-85 parts of a plasticizer, 0.3-1 part of a dispersant, 680-750 parts of powder filler, 7-13 parts of pigment, 35-45 parts of a polyurethane curing agent, 15-30 parts of silicon powder, 0.5-3 parts of an antifoaming agent, 0.1-1 part of a leveling agent, 85-96 parts of dimethyl carbonate, 25-38 parts of methyl o-hydroxybenzoate, 0.5-1.5 parts of cellulose triacetate and 0.5-2 parts of fatty alcohol polyoxyethylene ether. By synergistic cooperation of added methyl o-hydroxybenzoate, cellulose triacetate and fatty alcohol polyoxyethylene ether, anti-ultraviolet performance of silicon PU is enhanced, waterproof performance ofsilicon PU is enhanced, tensile strength of silicon PU is not easily affected by wind, rain and sunlight, and the service life of silicon PU is prolonged.

Description

technical field [0001] The invention relates to the field of plastic field materials, more specifically, it relates to a silicon PU for plastic field materials. Background technique [0002] Silicon PU is a healthy professional elastic synthetic court surface material system that conforms to the principles of ergonomics and meets the physical characteristics of sports. Silicon-modified polyurethane is used as a cushioning and rebounding structure, and two-component modified acrylic acid is used as a wear-resistant surface layer, which is generally used in basketball courts, badminton courts and other sports venues. [0003] Although silicon PU has good elasticity and certain wear resistance, and its various performances are superior to those of traditional cement or wooden floor courts, however, silicon PU is not resistant to wind, rain and sunlight. It is prone to hardening, stickiness, loss of strength and other phenomena, which easily affects the service life of silicon ...
