Abstract

The invention provides an anticorrosive paint used in waste gas treatment equipment and a preparation method thereof, and relates to the technical field of anticorrosive materials. The anticorrosive paint comprises the following raw materials in parts by weight: acrylic acid, n-butyl acetate, N-methyl pyrrolidone, VAE emulsion, laurinol polyoxyethylene ether, acetone, palygorskite, lithium-based bentonite, nanometer silica, nanometer titania, ethylene glycol monomethyl ether, polyurethane, graphite, talcum powder, acetylacetone, a thickener, a flatting agent, a phenol antioxidant and a compatilizer; the preparation method comprises the following steps: (1) weighing the raw materials; (2) preparing a base material; (3) preparing a mixed nanometer material; (4) preparing the modifier; (5) mixing, stirring, cooling and packaging. The anticorrosive paint overcomes the disadvantages that the anticorrosive base treatment requirement is high, the coating is too thick and is easy to crack, thepaint film is greatly influenced by temperature and humidity during curing, the curing time is long and the paint is low in weather resistance and not high in adhesive property existing in the anticorrosive paint used in the waste gas treatment equipment in the prior art.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion coatings, and in particular relates to an anticorrosion coating for waste gas treatment equipment and a preparation method thereof. Background technique [0002] In the waste gas treatment process, due to the doping of a large amount of corrosive substances in the waste gas, it is easy to corrode the waste gas treatment equipment, which shortens the service life of the waste gas treatment equipment. Therefore, in order to prevent the exhaust gas treatment equipment from being corroded, anti-corrosion coatings are usually used on the exhaust gas treatment equipment, but the main problems of the existing anti-corrosion coatings are: high requirements for anti-corrosion substrate treatment, too thick coating film is easy to crack, and when the paint film is cured It is greatly affected by temperature and humidity, takes a long time to cure, and most of them have the disadvantages of poor weathe...
