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 perfluorooctyl-triethoxysilane 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 t...

Abstract

The invention discloses a stain-resistant latex paint. The stain-resistant latex paint is characterized by comprising formulas with the following mixing amounts in percentage by weight: (1) 17-19% of ammonium tungstate, (2) 5-7% of deionized water, (3) 4-6% of tetraethyl orthosilicate, (4) 2.5% of absolute ethyl alcohol, (5) 2.5% of hydrochloric acid, (6) 2-3% of perfluorooctyl-triethoxysilane, (7) 1.2% of a silane coupling agent, (8) 54-56% of polyester resin, (9) 4% of a curing agent namely methyl ethyl ketone, (10) 0.6% of an organic silicon leveling agent, (11) 1.5% of titanium dioxide, and (12) 1% of distilled water. The prepared latex paint disclosed by the invention has the advantages of strong stain resistance, good cost performance and the like.

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...
