Waterborne epoxy anticorrosive paint and preparation method thereof

Abstract

The invention discloses a waterborne epoxy anticorrosive paint which comprises a grinding part, a paint mixing part and a color paste part, and the paint mixing part is prepared from the following rawmaterials in percentage by mass: 45% of a water-based epoxy resin emulsion; 0.5 part of a drier; and 1.0 of an amine neutralizer; the grinding part is prepared from the following raw materials in percentage by mass: 10% of water; 0.5% of a dispersant; 0.2% of an antifoaming agent; 0.4% of a wetting agent; 2-10% of a pigment; 0-5% of filler; and the color paste part is prepared from the followingraw materials in percentage by mass: 0.3% of a leveling agent; 0.3% of a substrate wetting agent; 0.5% of an anti-flash rust agent; 1.5% of a salt spray resistant auxiliary agent; 2%-6% of a coalescing agent; 0.3%-0.5% of a thickening agent; and the balance water. According to the waterborne epoxy anticorrosive paint with the above structure, water is used as a solvent to replace an organic solvent which is relatively high in price and can generate pollution, so that the cost is reduced, and no pollution is generated to the environment; meanwhile, by adding the water-based epoxy resin emulsion, a cured coating film is excellent in corrosion resistance and chemical resistance, obvious in corrosion resistance and anti-freezing effect and excellent in operability.

Description

technical field [0001] The invention relates to a paint technology, in particular to a water-based epoxy anticorrosion paint and a preparation method thereof. Background technique [0002] Paint, commonly known as paint. 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, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. Traditional metal anti-corrosion coatings are almost all solvent-based coatings, and a large amount of solvent volatilizes during the film-forming process. Volatile solvents not only cause harm and pollution to the human body and the surrounding environment, but also cause a waste of resources. With the continuous improvement of environmental requirements, the continuous strengthening of environmental protection awaren...
