Problems solved by technology

With the society's increasingly stringent requirements for energy conservation and environmental protection, coating products gradually show a development trend of high performance, zero volatility, and zero pollution. Fluorocarbon coatings are coatings that use fluorocarbon resins as film-forming substances. The existence of the F-C bond makes the fluororesin coating with fluororesin as the base material have excellent performance, but the waterproof performance of the traditional fluorocarbon resin-based powder coating cannot meet the needs of users

Abstract

The invention relates to the technical field of compound design of water-resistant powder paints, particularly a high-water-resistance fluorocarbon powder paint which comprises a fluorocarbon resin, an epoxy modified alkyd resin, a carboxyl-terminated polyester resin, a bismaleimide resin, triethanolamine, dibutyltin dilaurate, 2-(2-aminoethoxy) ethanol, triallyl isocyanurate, aluminum tripolyphosphate, a silane coupling agent, graphene, nano silicon dioxide, nano titanium dioxide, polyethylene wax, precipitated barium sulfate and calcium fluoride. The powder paint has high water resistance; the coating has the advantages of high adhesion with the substrate, compact and smooth surface, favorable scratch resistance and favorable friction resistance, and is applicable to the fields of rail transit (high-speed rails, subways, light rails and the like), oil-gas water pipelines, ship industry, indoor / outdoor metal structural member engineering, electric appliance metal industry and other fields related to human domestic and industrial manufacturing.

Description

technical field [0001] The invention relates to the technical field of formulation design of waterproof powder coatings, in particular to a fluorocarbon powder coating with good waterproof performance. Background technique [0002] Powder coating is a coating product that has developed rapidly in recent years. It has the characteristics of solvent-free, recyclable powder and high utilization efficiency. With the society's increasingly stringent requirements for energy conservation and environmental protection, coating products gradually show a development trend of high performance, zero volatility, and zero pollution. Fluorocarbon coatings are coatings that use fluorocarbon resins as film-forming substances. The existence of F-C bonds makes the fluororesin coatings formulated with fluororesin as the base material have excellent performance, but the waterproof performance of traditional fluorocarbon resin-based powder coatings cannot meet the needs of users. In view of the a...
