Abstract

The invention relates to the technical field of anti-corrosion and anti-static coating, and discloses an anti-static epoxy ester modified styrene-acrylic resin anti-corrosion coating, which comprisesthe following raw materials in parts by weight: epoxy ester modified styrene-acrylic resin, modified styrene-acrylic resin curing agent, catalyst, distilled water, filler, cosolvent and 0.1-0.3 partsof organic silicone defoamer, wherein the modified styrene-acrylic resin curing agent is hydrophilic polyamide curing agent and the catalyst is benzoyl peroxide. According to the antistatic epoxy ester modified styrene-acrylic resin anticorrosive coating, the epoxy ester modified styrene-acrylic resin is formed by using epoxy resin and gamma-linoleic acid as raw material to synthesize styrene-acrylic emulsion and in the process of emulsion film formation, it can be further crosslinked and cured, which can solve the problem of insufficient compactness of the coating film and improve the anti-corrosion performance. The catalyst is benzoyl peroxide, and a small amount of polyacyl ester benzene methyl acrylate polymer is generated to form a network conductive network, so that the emulsion hasstable conductive performance, thus the coating has anti-static function.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion and anti-static paint preparation, in particular to an anti-static epoxy ester modified styrene-acrylic resin anti-corrosion paint. Background technique [0002] Corrosion is the process of loss and damage of metal, concrete, wood and other objects by the chemical or electrochemical action of the surrounding environment medium (water, air, acid, alkali, salt). Economic loss, the process of preventing or slowing down corrosion has long been practiced using a variety of techniques. [0003] At present, the anti-corrosion coatings on the market are mainly divided into vinyl chloride anti-corrosion coatings, zinc-rich anti-corrosion coatings and resin anti-corrosion coatings. Among them, resin anti-corrosion coatings are hard and brittle after curing of epoxy resin, not weather-resistant, not UV-resistant, and poor impact resistance. , The anti-static performance is poor, and the recoatability...
