Problems solved by technology

The main problem of the current high-gloss metal powder coatings is that the surface of the coating has poor finger-touch resistance, that is, after human hands touch the coating, the sweat stains left on the coating surface are not only difficult to remove, but also cause rapid oxidation and discoloration of the metal flakes , seriously affects the appearance of the coated product, and also restricts the popularization and application of high-gloss metal powder coating products
[0004] Existing technicians have improved the product formula by adding high-gloss wax, anti-scratch agent and other measures, but the effect is not obvious
At present, the measure of adding a transparent protective layer is mainly adopted, which not only complicates the coating process, but also significantly increases the cost of product coating

Abstract

The invention relates to a high-glass metal powder coating which is prepared from a base material, a floating metal pigment, a powder treatment agent and a functional auxiliary by adopting a dry-mixing method, wherein the base material comprises resin, a curing agent, a flatting agent, filler and pigments and a degassing agent and is prepared by high-speed mixing, melt extrusion and abrasive powder sieving. Then, the product provided by the invention is prepared by adopting a dry-mixing and adhering process with the base material which is added in two steps. By virtue of granular control of a cellulose acetate butyrate material and the two-step dry-mixing process, the appearance effect and the distinctness of a coating are remarkably improved while the dispersing effect of cellulose acetate butyrate and metal pigments is improved and the adhering effect and efficiency of the metal pigments are enhanced, the glossiness of the coating reaches over 50% (60 DEG C), and particularly, the touch pollution resisting capability of the surface of the metal coating is remarkably enhanced. The whole quality of the product is comprehensively enhanced.

Description
