Problems solved by technology

However, the style of fluorocarbon coating is single, generally has a leveling appearance, and the coating is often accompanied by disadvantages such as pinholes, the decorative effect is not strong, and it cannot meet individual needs
Moreover, due to the weak polarity of the fluororesin itself, the original texture additives have no effect on it or the effect is not obvious, so there is no fluorocarbon powder coating with a texture effect at present.

Abstract

The invention discloses perfluorocarbon powder paint. The paint comprises the following components in parts by weight: 150-250 parts of fluororesin, 20-80 parts of isocyanate resin, 0-10 parts of accelerant, 0-100 parts of filler, 0-10 parts of flatting agent, 0.5-5 parts of benzoin, and 0-50 parts of pigment. The invention also discloses a preparation method of the powder paint. The powder paint is simple in prescription, fluororesin and isocyanate resin are adopted as a curing system, the texture is strong in stereoscopic sense and good in decoration effect, the curing coating has super-weather resistance and long outdoor service life, and is relatively low in using and maintaining comprehensive cost.

Description

technical field [0001] The invention relates to a powder coating, in particular to a fluorocarbon powder coating with a texture effect, and simultaneously the invention also relates to a preparation method of the powder coating. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder coating, which has the characteristics of no solvent, no pollution, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of the coating film. At present, the appearance of powder coatings after film formation mainly includes leveling, sand lines, wrinkles, matting, etc. These coating films mainly provide protection for the substrate, but are not decorative or artistic. With people's more and more personalized needs, some art coating products with special texture effects have appeared in the industry, such as moiré, mesh, crocodile skin, etc., but the weather resistance of such powder coatings...
