Abstract

The invention relates to the technical field of coatings, and in particular discloses a crylic acid modified polyurethane dispersion wall coating and a preparation method thereof. The wall coating comprises the following components in percentage by weight: 7-25% of deionized water, 1-2% of a base material moistening agent, 0.1-0.3% of rheologic aids, 14-25% of titanium dioxide, 50-75% of a crylic acid modification polyurethane dispersion, 1-6% of filming aids, 0.1-0.4% of an organic silicon surfactant, 0.2-0.5% of a defoaming agent and 0.35-0.7% of a polyurethane thickening agent. The wall coating has dual advantages of crylic acid and polyurethane, can be directly diluted with water, is appropriate in price, is dense in coating film after being filmed in a cross-linking manner, has very good impedance to stain, and is very good in mold resistance, bacterial resistance and stain resistance and high in film hardness.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to an acrylic modified polyurethane dispersion wall coating and a preparation method thereof. Background technique [0002] Now our country is in a period of rapid development. The total building area has increased significantly year by year, and the building decoration materials industry has also developed rapidly with the development of real estate and building decoration industries.
