Problems solved by technology

At present, the commonly used method is to spray anti-corrosion and anti-corrosion coatings on the outside of the metal, but the existing anti-rust coatings have poor anti-rust performance, high abrasion rate, and most of them have low tolerance to alkaline corrosion, short service life, and weak adhesion. The low flatness of the coating surface and long drying time greatly limit the use of the coating

Abstract

The invention provides a high-performance anti-corrosion coating for metal surface treatment. The high-performance anti-corrosion coating for metal surface treatment is prepared from the following components in parts by mass: 30-45 parts of silica sol, 12-16 parts of epoxy resin, 8-15 parts of polyimide resin, 2-4 parts of ketimine, 2-5 parts of fluorite powder, 1-3 parts of aminosilane, 2-4 partsof polyethylene glycol, 3-6 parts of hydroxyalkylphenol polyoxyethylene ether, 3-8 parts of 8-hydroxyquinoline copper, 4-10 parts of an antirust agent and 5-10 parts of a corrosion inhibitor. The high-performance anti-corrosion coating has the advantages of excellent corrosion resistance, excellent rust resistance, acid and alkali resistance, smooth coating, uniform paint dispersion, high adhesive force and high drying speed, and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a high-performance anti-corrosion paint for metal surface treatment. Background technique [0002] Steel is the most commonly used structural material with unstable thermodynamic properties, and it will inevitably corrode when exposed to the atmosphere, thus transforming into loose rust. The loss of various metal components and equipment in our country due to corrosion is as high as tens of billions every year, so it is necessary to take effective anti-rust measures. At present, the commonly used method is to spray anti-corrosion and anti-corrosion coatings on the outside of the metal, but the existing anti-rust coatings have poor anti-rust performance, high abrasion rate, and most of them have low tolerance to alkaline corrosion, short service life, and weak adhesion. The low flatness of the coating surface and the long drying time greatly limit the use of the c...
