Abstract

The invention belongs to the technical field of anticorrosive coatings, and particularly discloses a production and preparation method of an anticorrosive coating. The following scheme is provided: the method comprises the following process steps: preparing the following raw materials in parts by weight: 12-33 parts of barite, 6-19 parts of polytetrafluoroethylene, 7-13 parts of flaky graphene, 4-17 parts of nano silicon carbide, 6-15 parts of graphite, 4-14 parts of black stone powder, 4-18 parts of barium sulfate, 7-15 parts of yttrium oxide, 2-9 parts of an accelerant, 3-8 parts of a curingagent and 60-70 parts of water; and crushing and sieving the barite, wherein filter sieve pores are 150-200 meshes. The prepared coating can resist oxidation corrosion of strong oxidizing materials such as a strong intermediate of a concentrated acid solution and a polar solvent for a long time, physical reaction and chemical reaction of an acid-base corrosion medium are effectively prevented, and the coating is high in hardness, resistant to impact, smooth and full and has the characteristics of high thermal shock resistance coefficient and good adhesive force.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a production and preparation method of anti-corrosion coatings. Background technique [0002] Among the strong oxidation resistant materials, 37% hydrochloric acid, 98% sulfuric acid, 65% nitric acid, sodium hypochlorite aqueous solution (12% active chlorine), 30% hydrogen peroxide, 50% chromic acid, ozone water, glacial acetic acid, silicon tetrachloride, high Potassium manganate, etc. are oxidizing and corrosive. These strong oxidizing materials have the property of easily obtaining material electrons and being reduced to oxidize other substances. Elements in substances with strong oxidizing properties generally have a high valence state and have a strong ability to obtain electrons; such as concentrated sulfuric acid, concentrated nitric acid, potassium permanganate, etc. have strong oxidizing properties and can chemically react with most metals. Under strong...
