Abstract

The invention relates to the field of fluorocarbon coatings, and particularly discloses corrosion-resistant strong-adhesion FEVE water-based fluorocarbon color paste and a preparation method thereof. The color paste is prepared from 50 to 60 parts of FEVE water-based fluorocarbon emulsion, 10 to 30 parts of deionized water, 3 to 15 parts of pigment filler, 0.5 to 2.0 parts of defoaming agent, 0.5 to 1.0 part of thickening agent, 0.2 to 1.0 part of dispersing agent, 0.5 to 2.0 parts of curing agent, 0.2 to 0.5 part of flatting agent and 3 to 5 parts of modified material; the modified material is a nano-hydroxyapatite-hyperbranched modified composite material, and the particle size of nano-hydroxyapatite is 2-100 [mu] m. The preparation method comprises the following steps: S1, grinding; s2, mixing; and S3, dispersing. The hyperbranched material is adopted to stabilize the nano hydroxyapatite particles, so that the adhesion performance of the FEVE water-based fluorocarbon color paste after coating is improved, and the corrosion resistance of the FEVE water-based fluorocarbon color paste is further improved.

Description

Technical field [0001] The present application relates to the field of fluorocarbon coatings, and more particularly to a corrosion-resistant adult FEVE aqueous fluorocarbon color slurry and a preparation method thereof. Background technique [0002] Fluorine resin means a hydratric molecule compound containing a fluorine atom in a carbon atom of the main chain or a side chain to form a fluorine-containing homopolymer or thereof as a main film having a monomer copolymer. The fluororesin assisted the color paste prepared by various additives and pigments, and finally formed as a fluorocarbon resin color paste. The traditional solvent-based color paste contains a large number of volatile organic compounds, which will volatilize into the atmosphere during use, but not only cause waste, but also cause serious environmental pollution, which seriously affects people's health. [0003] Water-based Feve fluorocarbon resin slurry is mainly in emulsion type, including aqueous single-compone...
