Novel high-grade powder coating and preparation method thereof

Abstract

The invention discloses a novel high-grade powder coating and a preparation method thereof. The problems that the existing powder coating is poor in impact strength and acid and alkali resistance, thelubricity of the powder coating cannot meet the use requirements, in addition, in the powder coating production process, the problem of oxidative decomposition of body resin is easily caused due to the problems of an agent discharging method, the quality of the powder coating is further influenced are solved. The matching of the powder coating and the synthesis method of the powder coating are improved and optimized, so the powder coating has high impact strength, strong acid resistance, alkali resistance, salt spray resistance and weather resistance, and flat and smooth coating surface, thecuring time can be shortened, the purposes of energy conservation, low carbon and environmental protection are achieved, and the use performance of the powder coating is improved; and matrix resin oxygenolysis can be avoided by adopting a deep thread low-temperature extrusion method in the production process of the powder coating. Double-screening fine grinding is adopted to guarantee that matrixresin particles are small and uniform, so thin coating can be conducted, and the coating effect is better.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a novel high-grade powder coating and a preparation method thereof. Background technique [0002] As a new type of coating with high performance, low pollution, less pollution and energy saving, powder coating has become one of the main products replacing traditional solvent-based coatings. Over the past few years, with the continuous improvement of my country's coating technology level and quality requirements, powder coatings have replaced paint and become the most ideal product for coating and anticorrosion of metal surfaces, especially high-grade metal surfaces. However, the existing powder coatings and synthesis methods in my country have the following problems : The impact strength and acid and alkali resistance of the existing powder coatings are poor, the lubricity of the powder coatings cannot meet the requirements of use, and the problem of the oxidation and decom...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of high-grade powder coating and its preparation method, aiming to improve the impact strength and acid and alkali resistance of existing powder coatings, the lubricity of powder coatings cannot meet the needs of use, and the powder The process of coating production is likely to cause the problem of oxidative decomposition of the body resin due to the problem of the agent release method, which in turn affects the quality of the powder coating.
