Abstract

The invention relates to a water-based high-performance water-based two-component epoxy primer with high salt spray resistance, excellent water resistance and excellent chemical resistance and a preparation method thereof. The primer is composed of a component A and a component B, a mass ratio of the component A to the component B is 3-5: 1, wherein the component A comprises the following components in parts by weight: 30-70 parts of water-borne epoxy resin emulsion, 0.1-5 parts of a surface additive, 1-15 parts of a coalescing agent, 5-15 parts of an antirust filler, 0.1-2 parts of an anti-settling agent, 0.1-1 part of an adhesion promoter, 0.1-1 part of a thickening agent, 5-30 parts of a pigment and 5-10 parts of deionized water; and the component B comprises the following components inparts by weight: 40-70 parts of an aliphatic amine curing agent, 1-5 parts of an anti-flash-rust auxiliary agent and 20-40 parts of deionized water. According to the invention, the emulsion, the antirust pigment and the auxiliary agent are enhanced, and the stability of a finished product and the resistance of a paint film are greatly improved by optimizing a manufacturing process.

Description

technical field [0001] The invention belongs to a water-based industrial coating, in particular to a high-performance water-based two-component epoxy primer with excellent water-based high salt spray resistance, water resistance and chemical resistance and a preparation method thereof. Background technique [0002] Traditional solvent-based coatings will release a large amount of volatile organic compounds during the film-forming process, causing pollution to the environment. Water-based industrial coating is an environmentally friendly industrial paint. Its low VOC emission reduces air pollution, reduces the risk of flammability and explosion during transportation and storage, and improves construction safety. Compared with solvent-based paints, water-based paints have great advantages in terms of energy saving and environmental protection. However, the current water-based epoxy primer still has technical defects, such as poor water resistance, salt spray resistance, acid ...
