Abstract

The invention particularly relates to an environment-friendly FEVE (trifluorochloroethylene copolymer) fluorocarbon coating and a preparation method thereof. The environment-friendly FEVE fluorocarbon coating is prepared from, by weight, 20-30 parts of an FEVE emulsion, 20-30 parts of epoxy-based silane modified silica sol, 1.0-2.0 parts of a coalescing agent, 0.1-1.0 part of a viscosifier, 0.2-1.0 part of a polyurethane thickening agent and 30-60 parts of color paste; the color paste is prepared from, by weight, 33% of water, 0.3% of a multifunctional agent, 0.3% of a cellulosic thickener, 0.4% of a wetting agent, 0.9% of a dispersing agent, 0.1% of a defoamer, 47% of titanium dioxide, 9% of mica powder and 9% of wollastonite powder. The environment-friendly FEVE fluorocarbon coating is free from organic solvents of benzene, methylbenzene, xylene, ethylbenzene and the like and harmful substances like free diisocyanate to human bodies and environment, excellent in alkali resistance, water resistance, aging resistance, corrosion resistance, washability, adhesive force and strain resistance and broad in market prospect.

Description

technical field [0001] The invention specifically relates to an environment-friendly FEVE fluorocarbon paint and a preparation method of the environment-friendly FEVE fluorocarbon paint. Background technique [0002] The development of economy and society has also brought about the rapid development of the construction market, especially high-rise buildings, high-end residences, urban viaducts, highway bridges, etc., which are developing at a rate of 20% every year, and the demand for high-standard coatings for building exterior walls is also increasing day by day. [0003] Solvent-based FEVE resin coatings can be cured at room temperature, and can also be baked and cured at medium and low temperatures. The formation of low-altitude ozone destroys the atmospheric environment, VOC and suspended particles form secondary aerosols, which endanger human health, and because it is a two-component coating, it is necessary to use diisocyanate monomers as curing agents, which not only...
