Embodiment 1

[0053] In the mixer, add 5 parts of water, 10 parts of titanium dioxide, 9 parts of additives (including 1 part of chain extender, 2 parts of leveling agent, 3 parts of dispersant, 1 part of thickener, 0.5 parts of defoamer, 1 part of dustproof agent), 12 parts of filler (ultrafine talc powder: mica powder = 1:1), stir evenly, grind the resulting solution through a sander to a particle size of less than 40 microns, and then put the solution back into the mixer, Dissolve the mixed solvent with the antifungal agent and the leveling agent in the mixed solvent to obtain the antifungal solvent for later use; put the silane adhesion promoter, water-curable polyurethane and water-based acrylic resin into the mixer, and step (2) and ( 3) Mix the solution and anti-mildew solvent in , stir evenly, and you get it.

Embodiment 2

[0055] Add 8 parts of water, 6 parts of titanium dioxide and 13 parts of additives (including 3 parts of chain extender, 2 parts of leveling agent, 1 part of dispersant, 3 parts of thickener, 1.5 parts of defoamer, 2 parts of dust agent), 16 parts of filler (ultrafine talc powder: mica powder = 1:1), stir well, and grind the resulting solution through a sander to a particle size of less than 40 microns, and then put the solution back into the mixer. Dissolve the mixed solvent with the antifungal agent and the leveling agent in the mixed solvent to obtain the antifungal solvent for later use; put the silane adhesion promoter, water-curable polyurethane and water-based acrylic resin into the mixer, and step (2) and (3) ) solution, anti-mold solvent, mixed, stirred evenly, that is.

Embodiment 3

[0057] Add 6 parts of water, 7 parts of titanium dioxide, 8 parts of additives (including 1 part of chain extender, 1 part of leveling agent, 2 parts of dispersant, 1 part of thickener, 1 part of defoamer, 1 part of dustproof agent), 14 parts of filler (ultrafine talc powder: mica powder = 1:1), stir evenly, grind the resulting solution through a sander to a particle size of less than 40 microns, and then put the solution back into the mixer, Dissolve the mixed solvent with the antifungal agent and the leveling agent in the mixed solvent to obtain the antifungal solvent for later use; put the silane adhesion promoter, water-curable polyurethane and water-based acrylic resin into the mixer, and step (2) and ( 3) Mix the solution and anti-mildew solvent in , stir evenly, and you get it.

[0058] According to GB / T1723-93, GB / T 1724-89, GB / T 1731-93, GB / T 1732-93, GB / T1733-93, GB / T 1734-93 standards, the results are listed in the table below.

Abstract

The invention discloses polyurethane internal wall building mildew-proof paint. The polyurethane internal wall building mildew-proof paint is mainly prepared from water-cured polyurethane, water-based acrylic resin and a mildew-proof agent; disadvantages of single polyurethane or single polyacrylic resin, such as poor stability, white thickening property and gloss retention of a film, high solid content and a narrow application range, are overcome; the main components have a complementary action on properties. The composite paint combines advantages of the polyurethane and the acrylic resin and has the characteristics of mildew prevention, wearing resistance, corrosion resistance and brightness, softness and elasticity, good water resistance and mechanical properties, excellent weather resistance and the like, and also has high glossiness, high elasticity and excellent weather resistance. Compared with other traditional polyurethane paint, the polyurethane internal wall building mildew-proof paint has the advantages of convenience for construction, no toxin and no pollution, and is more environment-friendly and the like.

Description

technical field [0001] The invention relates to a building coating, in particular to a polyurethane building anti-mildew coating. Background technique [0002] Due to the increasingly developed world industry and the destruction of nature by humans, energy conservation and consumption reduction has attracted the attention and attention of countries all over the world. my country's building energy consumption accounts for more than 30% of human energy consumption. Improve the thermal insulation performance of buildings and improve The use function of buildings, energy saving and consumption reduction are another important considerations in the design of building material selection. In the field of architectural coatings, the development goals at home and abroad are also developing in the direction of high efficiency, energy and resource saving, harmlessness and pollution-free. The architectural heat-reflecting and heat-insulating coatings developed in recent years are not onl...
