Waterborne epoxy wall finish paint and preparation method thereof

Abstract

The invention discloses waterborne epoxy wall finish paint and a preparation method thereof and relates to the technical field of chemical engineering. The waterborne epoxy wall finish paint comprises a component A and a component B, wherein the component A comprises 20-30 parts of waterborne epoxy acrylate resin and 5-10 parts of water; the component B comprises 10-15 parts of water-soluble saturated polyester resin, 2-5 parts of water-soluble amino resin, 0.2-0.5 part of polyether-modified silicone, 10-20 parts of titanium dioxide powder, 10-30 parts of calcium carbonate, 8-15 parts of talc powder and 7.5-11.8 parts of water. Compared with the prior art, waterborne epoxy acrylate resin, water-soluble saturated polyester resin and water-soluble amino resin as film-forming materials are added and reacted to generate amino bonds with fungicidal and antifungal effects and thus the generation of mycete is prevented.

Description

technical field

[0001] The invention relates to the technical field of chemical industry, in particular to a water-based epoxy wall paint and a preparation method thereof. Background technique

[0002] Most of the current wall paints on the market use acrylic emulsion or modified acrylic emulsion as film former. The advantages of this type of product are many, but because the film-forming substance is a one-component acrylic emulsion, there are many shortcomings. For example, there are great deficiencies in various aspects such as wash resistance, mildew resistance, chemical resistance, and pollution resistance of the paint film. For example, some food and pharmaceutical factories need to clean the walls frequently, and sometimes they must use disinfectant water or lye for cleaning, which cannot meet their requirements at all for general wall paint. If the general wall paint is washed with water or lye for a long time, it will inevitably cause the wall paint to fall off or...
