[0033] Preparation of water-based glitter paint:

[0034] Pretreatment of aluminum silver paste or pearlescent pigment;

[0035] Stir the aluminum silver paste or pearlescent pigment, solvent, and wetting agent into a uniform paste, soak for more than 4 hours for later use;

[0036] Mix part of deionized water, antifreeze, and other additives (such as dispersant, defoamer, leveling agent) one by one, disperse at a slow speed for 20 minutes, slowly add fluorocarbon emulsion, and stir evenly;

[0037] Add film-forming aids and some deionized water one by one, and stir evenly;

[0038] Slowly add the well-stirred mixed solution into the soaked metal pigment slurry, and stir evenly at a slow speed.

Abstract

The invention relates to an acid rain resistant aqueous fluorocarbon coating used for external walls. The coating consists of the following raw materials in the following percents by weight: 55-75 percent of fluorocarbon emulsion, 5-35 percent of pigment, 0.2-2.2 percent of wetting and dispersing agent, 0-0.5 percent of neutralizing agent, 0.1-0.5 percent of antifoam agent, 0-0.5 percent of preservative, 0.1-5.0 percent of thickening agent, 0-5.0 percent of orienting agent, 0-10.0 percent of solvent, 1-6 percent of film forming agent, 1-3 percent of anti-freezing agent, and deionized water as the rest, wherein, the pigment is aluminum paste, pearl pigment, ceramic pigment, rutile titanium dioxide powder, chrome oxide green, cobalt blue, high quality carbon black or phthalocyanine blue. The acid rain resistant aqueous fluorocarbon coating for external walls can permanently protect the decorated buildings against corrosion of acid rain.

Description

technical field [0001] The invention relates to a coating, in particular to a coating for exterior walls. Background technique [0002] In my country's Southwest, Central China, and East China, there are three major acid rains, and the erosion of the outer wall by acid rain is increasing day by day. The use of common water-based coatings cannot meet the protection requirements of harsh acid rain for decorated buildings. How to manufacture a water-based coating with acid rain resistance is a problem for technicians to solve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water-based fluorocarbon coating with acid rain resistance function for exterior walls, aiming to solve the above-mentioned problems. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: [0005] The present invention is made up of following raw material by mass ...
