Processing and production method of anticorrosive latex paint

Abstract

The invention discloses a processing and production method of anticorrosive latex paint. The processing and production method comprises the following steps: step 1, preparation of modified zinc oxide powder; and step 2, weighing of the following raw materials: 55-65 parts of waterborne epoxy resin, 10-20 parts of modified zinc oxide powder, 5-10 parts of a blocking interface agent, 2-10 parts of polyester polyol, 1-3 parts of an assistant cross-linking agent, 1-2 parts of a curing agent and 50-60 parts of a solvent. According to the production method of the anticorrosive latex paint, the anticorrosive latex paint is prepared from the water-borne epoxy resin, the modified zinc oxide powder, the blocking interface agent, the assistant cross-linking agent and other raw materials, and the zinc oxide powder is modified to serve as a preservative, so the problem of poor interfacial compatibility of inorganic raw materials and epoxy resin in the prior art is solved; and in zinc oxide modification, zinc oxide is pre-calcined to activate the surface active energy of zinc oxide, and then polyethylene glycol and an ethanol solution are used as medium solvents.

Description

technical field [0001] The invention relates to the technical field of latex paint, in particular to a processing and production method of anti-corrosion latex paint. Background technique [0002] Latex paint is a large class of synthetic resin emulsion paints represented by acrylate copolymer emulsions. Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, and good scrub resistance. In my country, it is customary for people to use synthetic resin emulsion as the base material, use water as the dispersion medium, add pigments, fillers (also known as body pigments) and additives, and the paint made through a certain process is called latex paint, also called latex. coating.

Problems solved by technology

[0003] In the prior art, in order to improve the anti-corrosion performance of latex paint, zinc-based inorganic preservatives are added to latex paint to improve the anti-corrosion performance of latex paint. Although the corrosion resistance of latex paint can be improved, the problem of interface compatibility between inorganic zinc and organic raw materials is prone to occur. , it is difficult to significantly improve the corrosion resistance of the material

[0004] Disclosed a kind of water-based graphene conductive anticorrosion coating and preparation method thereof as Chinese patent document publication number CN111286258B, its raw material comprises component A and component B; Described component A is mainly prepared from the raw material of following weight part: water-based 40-60 parts of epoxy resin, 20-60 parts of filler, 2-4 parts of additives, 10-20 parts of water; the component B is mainly prepared from the following raw materials in parts by weight: graphene aqueous dispersion 5- 10 parts, 10-20 parts of zinc oxide, 40-60 parts of water-based epoxy curing agent; the preparation method of the graphene aqueous dispersion comprises the following steps: mixing graphene, carboxymethyl cellulose and water, shearing and dispersing for 1h -2h, the mixture is obtained; the mixture is ultrasonically treated for 3h-4h; the zinc oxide and graphene aqueous dispersions added in this document are likely to cause interfacial compatibility problems between the inorganic raw materials and the water-based epoxy resin, resulting in difficult corrosion resistance. significant improvement
