Problems solved by technology

[0004] However, the current powder coatings have poor impact resistance when the film thickness is high (greater than 100 microns), especially when the powder coating is sprayed too thick or reworked and re-sprayed, its impact resistance is even worse.

Abstract

The invention provides grit powder coating with high impact resistance.The grit powder coating comprises, by weight, 30-60 parts of epoxy resin, 20-30 parts of alkyd resin, 20-30 parts of organic silicon modified resin, 10-20 parts of fluorocarbon resin, 10-20 parts of polyetherimide, 1-10 parts of ethylenediamine, 1-10 parts of isophorone diamine, 1-10 parts of 1-methylimidazole, 1-10 parts of N-diglycidyl ether, 1-5 parts of sodium lignin sulfonate, 1-8 parts of polyethylene glycol, 1-5 parts of nanometer titanium dioxide, 1-5 parts of gas-phase silicon dioxide, 1-5 parts of light calcium carbonate, 1-3 parts of silane coupling agents, 1-3 parts of dimethyl siloxane, 1-3 parts of dibutyltin dilaurate, 1-3 parts of diatomaceous earth and 1-4 parts of grit agents.The grit powder coating and the method have the advantage that the grid powder coating is excellent in impact resistance under the condition of high film thicknesses (higher than 100 micrometers).

Description

technical field [0001] The invention relates to the field of coatings, in particular to a powder coating with high anti-scouring sand texture. Background technique [0002] Powder coating is a new type of solvent-free solid powder coating, which has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of the coating film. [0003] Powder coatings can be divided into thermoplastic powder coatings and thermosetting powder coatings. Thermoplastic powder is composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose and polyester. Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, fillers and additives. Thermosetting powder coatings include epoxy resin, ...
