Problems solved by technology

With the development of society, people have put forward higher requirements for the performance of epoxy resin coatings. The strength, corrosion resistance and water resistance of existing epoxy resin powder coatings are still not ideal. Epoxy resin powder coatings During the use of the coating, it is prone to aging, resulting in yellowing, cracking, falling off, etc., which shortens the service life of the coating, reduces the decorativeness of the coating, and limits its application.

Abstract

The invention discloses a high-strength water-resistant corrosion-resistant epoxy resin powder coating. The high-strength water-resistant corrosion-resistant epoxy resin powder coating is prepared from epoxy resin, polyester resin, modified polytetrafluoroethylene, silica sol, phenolic resin, tetra-methoxymethyl glycoluril, 2-phenylimidazole, 2-methylimidazole, 2-butyl-2-ethyl-1,3-propanediol, straw fiber, composite fillers, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, zinc isoocatanoate, an acrylic ester levelling agent, an organic silicon defoaming agent and an antioxidant, wherein the composite fillers are prepared through the following steps that wollastonite, nano zinc oxides, nano calcium carbonate, zinc borate, calcium sulfate, talcum powder and carboxymethylcellulose are added in a reacting device, glycerol is added, the mixture is stirred at the temperature of 55 DEG C-70 DEG C to be subjected to a reaction, the temperature is lowered, and then the composite fillers are obtained. The high-strength water-resistant corrosion-resistant epoxy resin powder coating is good in water resistance, high in strength, excellent in corrosion resistance, good in decorative property and long in service life.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a high-strength, water-resistant and corrosion-resistant epoxy resin 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, saving energy and resources, reducing labor intensity, and high mechanical strength of the coating film. It is divided into thermoplastic powder Coatings and thermosetting powder coatings. Due to its excellent adhesion, corrosion resistance, hardness, flexibility and impact strength, epoxy resin is the first variety used in thermosetting powder coatings. It has been widely used in household appliances, vehicles, hardware machinery and other fields. With the development of society, people have put forward higher requirements for the performance of epoxy resin coatings. The strength, corrosion...
