High-performance water-borne alcohol acid anticorrosive paint

Abstract

The invention relates to high-performance water-borne alcohol acid anticorrosive paint. The high-performance water-borne alcohol acid anticorrosive paint comprises a silicone modified water-borne alkyd resin, a cosolvent, a rust-proof composite pigment, a pigment filler, an auxiliary and deionized water; the silicone modified water-borne alkyd resin is prepared from vegetable oil fatty acid, organic anhydride, polyhydric alcohol, dimethylol propionic acid, a polysiloxane polyurethane acrylate monomer, an aromatic Schiff base, benzoic acid and a neutralizing agent through the reaction; and theprepared high-performance water-borne alcohol acid anticorrosive paint is excellent in water resistance, impact resistance, alkali resistance, ageing resistance, salt mist resistance and corrosion resistance, and the paint has an excellent antibacterial property without adding bactericide. The high-performance water-borne alcohol acid anticorrosive paint is widely used in the waterproofness and corrosion resistance of the surfaces of steel structures and concretes of buildings, chemical engineering, petroleum, electric power, metallurgy, ships, traffics, aerospace and the like.

Description

technical field [0001] The invention relates to a modified alkyd resin water-based coating, in particular to a high-performance water-based alkyd anti-corrosion coating, which belongs to the technical field of water-based functional coatings. Background technique [0002] Paint, traditionally called paint in China; the so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, It is a viscous liquid prepared with organic solvent or water with or without adding pigments, fillers, and corresponding additives. [0003] With the advancement of science and technology and the improvement of human living standards, people have higher and higher requirements for indoor environment and air quality, and more and more stringent requirements for the content of organic matter. For example, food, medicine and other industries need no harmful volati...

[0005] Chinese patent CN106118386A discloses an anti-corrosion coating, which is characterized in that it consists of the following raw materials in parts by weight: 15-20 parts of water-based acrylic modified epoxy resin, 10-15 parts of polymer resin emulsion, and 5-20 parts of silicon alloy powder. 10 parts, 3-6 parts of dibutyl phthalate, 12-16 parts of chlorinated paraffin, 6-9 parts of sodium hexaphosphoric acid, 4-8 parts of zinc-rich epoxy powder, 9-14 parts of talcum powder, 2 to 4 parts of thickener, has the advantages of good weather resistance, good anti-corrosion performance, strong adhesion and wear resistance. Dead angle, affecting anti-corrosion performance

[0006] Chinese patent CN106189761A discloses an anti-corrosion coating, including the following ingredients in parts by weight: 60-80 parts of nano-modified polyurea, 30-35 parts of titanium nanopolymer, 25-30 parts of epoxy resin, 16-30 parts of diatomaceous earth 22 parts, 8-12 parts of nano oxide particle reinforcing agent, 6-10 parts of hydroxyethyl cellulose, 5-12 parts of talcum powder, 12-25 parts of thickener, which have excellent anti-corrosion performance and strong adhesion Strong, high mechanical strength, high temperature resistance, suitable for weak corrosion environment, can reduce the cost of coating, but its anti-corrosion range is small, conditions are limited, it is difficult to meet a wide range of anti-corrosion requirements

[0007] Chinese patent CN105400247A discloses an environmentally friendly anti-corrosion coating, the components of which are: potassium silicate, acrylic resin, polyvinyl alcohol, kaolin, feldspar, cerium oxide, potassium hydroxide, distilled water, stabilizer, dispersant , defoamer, thickener, etc., choose inorganic fillers with suitable melting points, which will undergo complex physical and chemical reactions during high-temperature melting, and the fillers can dissolve the generated eutectic and molten materials during melting, Part of the volatile pigments and fillers of the raw materials start to sinter and melt to form a smooth glaze on the green body. In this process, the green body is porcelainized, and the inorganic fillers are vitrified at the same time, which improves the surface properties of the matrix and enhances the mechanical properties of the matrix. , so as to protect the metal, but the production and construction of its anti-corrosion coatings are relatively complicated, requiring high-temperature dissolution reaction, which can only be used in special fields, and it is difficult to meet the general anti-corrosion requirements
