Embodiment 1

[0056] The preparation of embodiment 1 coating 1

[0057] First, dissolve 0.15 parts of polyoxyethylene ether in deionized water, and use a disperser to dissolve ZrO with a particle size of 10-50nm 2 0.8 parts of nanoparticles are evenly dispersed in it, and set aside; 8 parts of mica powder, 5 parts of titanium dioxide, 1 part of Rebo-60, 1 part of MIT, 1 part of BIT, 0.8 parts of alkyltrimethylammonium chloride, and 1 part of Tego 245 Parts, 1 part of polydimethylsiloxane dispersed in deionized water, disperse for 20 minutes and then grind, when the grinding reaches about 15um, add 60 parts of acrylic emulsion, 28 parts of ethyl fumarate, 8 parts of allyl glycidyl ether 10 parts of polyisocyanate, 4 parts of ammonium persulfate, 7 parts of sodium vinyl sulfonate and ZrO 2 The nanometer solution was stirred rapidly for 3 hours, and the pH was adjusted to 9.0 with diethanolamine. The prepared paint is filtered and packed.

Abstract

The invention discloses an aqueous bottom-side rust-coated highlight anticorrosive coating and a preparation method thereof. Polyenoic acid ester monomers other than acrylic acid and monomers with functional groups which have carboxylic acid reactivity and can participate in a reaction in a phased mode are added in acrylic emulsion. The coating has excellent adhesion on the surface of rusted iron,can be coated with rust, and further has the characteristics of uniformity of the bottom surface; and more importantly, the prepared coating has good coating gloss, good storage stability, and good corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of metal surface anti-corrosion coating, in particular to a water-based anti-corrosion coating for bottom surface combined with rust coating and a preparation method thereof. Background technique [0002] With the rapid development of my country's economic construction and national economy, various steel structures, concrete structures, aluminum-plastic structures, etc. are more and more applied to bridges, buildings, ports, transportation and other industrial and civil projects, but they are easy to corrode. The characteristics of (rust) have brought huge economic losses to the equipment manufacturing industry, and are detrimental to natural resources and environmental protection. Among various anti-corrosion technologies, coatings play a very good role in protecting various engineering products and facilities. A series of anti-corrosion coatings have been developed at home and abroad, including rust coatin...
