Abstract

The invention discloses composite fluorocarbon resin coating with excellent adhesion. The coating is prepared from the following raw materials in parts by weight: 15-35 parts of modified FEVE fluorocarbon resin, 20-60 parts of epoxy modified alkyd resin, 20-35 parts of epoxy resin, 1-3 parts of dicyandiamide, 1-2 parts of sodium dodecyl benzene sulfonate, 3-8 parts of carboxymethylcellulose, 1-5 parts of ethylene glycol monoethyl ether acetate, 5-15 parts of super fine calcium carbonate, 2-10 parts of magnesium silicate, 5-15 parts of kaolin, 2-8 parts of talc powder, 2-6 parts of graphene, 2-8 parts of amyl acetate, 4-10 parts of propylene glycol, 1-3 parts of a wetting agent, 1-3 parts of preservative, 2-10 parts of ethyl acetate, 2-7 parts of butylated amino resin, 2-6 parts of methylated amino resin and 40-80 parts of water. The composite fluorocarbon resin coating has good adhesion and excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of fluorocarbon resin coatings, in particular to a composite fluorocarbon resin coating with excellent adhesion. Background technique [0002] With the increasingly stringent requirements of the society for energy conservation and environmental protection, coating products show a development trend of high performance, zero volatile organic compounds, and zero pollution. Fluorocarbon coating is a coating made of fluorocarbon resin as a film-forming substance. Due to the existence of F-C bonds in the macromolecular chain of fluororesin, the fluororesin coating formulated with fluororesin as the base material has many excellent properties, such as super-resistant Weather aging resistance, super anti-fouling ability, etc.; but the adhesion performance of traditional fluorocarbon resins cannot meet the demand, and the strong chemical corrosion performance needs to be improved urgently.
