AI Technical Summary

Technical Problem

Existing silicone coatings require the use of PFAS substances to increase abrasion resistance and smoothness, which leads to environmental and health risks. Other alternatives, such as PE wax powder and PP wax powder, do not perform well in terms of abrasion resistance and compatibility.

Method used

The fluorine-free wear-resistant silicone coating is composed of vinyl polysiloxane, hydrogen crosslinking agent, silicone wear-resistant and lubricating powder, silane coupling agent, matting agent, dispersant, organic solvent, thickener and metal catalyst. It forms a three-dimensional network structure through hydrosilylation reaction and crosslinking to ensure the wear resistance and smoothness of the coating.

Benefits of technology

It achieves long-term adhesion, surface enhancement, and extended product life of fluorine-free coatings, while meeting environmental protection requirements, providing excellent wear resistance and a smooth feel, and is suitable for various environmental conditions.

Abstract

The application belongs to the technical field of paint, and particularly relates to a fluorine-free wear-resistant organic silicon paint, a preparation method and application thereof, wherein the fluorine-free wear-resistant organic silicon paint is composed of the following components in mass fraction: 25-35 parts of vinyl polysiloxane, 2-10 parts of hydrogen-containing crosslinking agent, 1-8 parts of organic silicon wear-resistant and slip powder, 2-5 parts of silane coupling agent, 3-9 parts of matt powder, 1-2 parts of dispersing agent, 40-60 parts of organic solvent, 1-3 parts of tackifier, 0.3-1.5 parts of inhibitor and 1-8 parts of metal catalyst. Compared with the prior art, the fluorine-free wear-resistant organic silicon paint provided by the application can meet the requirements of PFAS and anti-allergy when applied to an elastomer substrate, and the combination and dispersion uniformity of the organic silicon wear-resistant and slip powder and the vinyl polysiloxane after kneading treatment of the silane coupling agent are higher, so that the fluorine-free wear-resistant organic silicon paint has sufficient wear resistance and delicate slipperiness.
