Abstract

The invention discloses matte epoxy powder coating and a preparation method of the matte epoxy powder coating. The matte epoxy powder coating comprises, by weight, 500 parts-600 parts of epoxy resin (E-12), 10 parts-15 parts of dicyandiamide (DICY), 8 parts-12 parts of a flatting agent (GLP503), 3 parts-5 parts of brightener (BLC701), 4 parts-6 parts of benzoin, 5 parts-8 parts of modified polyamide wax micro powder, 4 parts-6 parts of degasifier (SA500), 3 parts-5 parts of flow promoter (W-1), 5 parts-10 parts of an extinction agent (XG603-1F), 150 parts-200 parts of extinction barium sulfate, 50 parts-100 parts of torispherical silica powder, 5 parts-8 parts of 2-phenyl-imidazoline, 4 parts-5 parts of carbon black, 7 parts-10 parts of iron oxide yellow, 3 parts-5 parts of iron oxide red and 4 parts-6 parts of titanium dioxide. The prepared matte epoxy powder coating has the advantages of being high in hardness, high in intensity, high in wear resistance, good in heat resistance, good in aging resistance, short in curing time, environment-friendly, pollution-free, and the like. The matte epoxy powder coating is excellent in performance, and is high in performance indexes of acid-base resistance, salt mist resistance, and organic solvent resistance, wherein the organic solvent includes gasoline.

Description

technical field [0001] The invention relates to a powder coating, in particular to a matt epoxy powder coating and a preparation method thereof. Background technique [0002] As an environmentally friendly coating, powder coating has the advantages of no solvent, low pollution, simple coating process and high coating efficiency, and has been developed rapidly. Among them, matt epoxy powder coating is a commonly used powder coating, which has excellent physical properties and chemical resistance, and has good electrical insulation properties. However, due to its disadvantages such as poor weather resistance and poor thermal stability, its application range is limited. Contents of the invention [0003] The object of the present invention is to provide a kind of matt type epoxy / polyester powder coating and preparation method thereof, improve the weather resistance, heat resistance and aging resistance of matt type epoxy powder coating, prolong its service life, expand its ...
