Embodiment Construction

[0046] The stain-resistant latex paint formula is as follows in the present embodiment:

[0047] (1) The dosage of ammonium tungstate is 18%,

[0048] (2) The dosage of deionized water is 6%,

[0049] (3) Tetraethyl silicate dosage is 5%,

[0050] (4) absolute ethanol dosage is 2.5%,

[0051] (5) hydrochloric acid dosage is 2.5%,

[0052] (6) The dosage of perfluorooctyltriethoxysilane is 2.4%,

[0053] (7) The dosage of silane coupling agent is 1.2%,

[0054] (8) The polyester resin content is 55.3%,

[0055] (9) The dosage of curing agent methyl ethyl ketone is 4%,

[0056] (10) The dosage of silicone leveling agent is 0.6%,

[0057] (11) The dosage of titanium dioxide is 1.5%,

[0058] (12) The dosage of distilled water is 1%.

[0059] The invention utilizes the small size effect of nanoparticles to form a super-hydrophobic layer on the surface of the paint layer. The inorganic dust in the air generally has a certain polarity and cannot form strong adsorption on th...

Abstract

The invention discloses a stain-resistant latex paint, which is characterized in that the formula is as follows: (1) the dosage of ammonium tungstate is 17-19%, (2) the dosage of deionized water is 5-7%, (3) The dosing amount of ethyl orthosilicate is 4-6%, (4) the dosing amount of absolute ethanol is 2.5%, (5) the dosing amount of hydrochloric acid is 2.5%, (6) the dosing amount of perfluorooctyl-triethoxysilane (7) The dosage of silane coupling agent is 1.2%, (8) The dosage of polyester resin is 54-56%, (9) The dosage of curing agent methyl ethyl ketone is 4%, (10) The dosage of silicone Leveling agent dosage is 0.6%, (11) titanium dioxide dosage is 1.5%, (12) distilled water dosage is 1%. The latex paint prepared by the invention has the advantages of strong stain resistance and good cost performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a stain-resistant latex paint. Background technique [0002] Stain resistance has always been one of the important indicators for investigating the performance of architectural latex paints. In view of the fact that the stain resistance of architectural latex paints, especially exterior wall latex paints, is not ideal, latex paints with stain resistance have received more and more attention. more attention. But for a long time, the concept of stain-resistant facades has often been negatively associated with chalked facades. However, the shortcomings of the powder self-cleaning system are very obvious. First, it will reduce the thickness of the paint film, making the paint film lose its luster, and the uneven powdering will also cause the paint film to bloom, especially for dark latex paint. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the o...
