Problems solved by technology

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 paints.

Abstract

The invention discloses stain-resistant exterior wall emulsion paint which is prepared from the following components: deionized water, bamboo charcoal powder, an antifoaming agent, coco fatty acid diethanol amide, titanium dioxide, polyethylene glycol, carboxyl coated diatomite and nano-silica mixed particles, calcium carbonate, silicon powder and acrylic emulsion. According to the stain-resistant exterior wall emulsion paint provided by the invention, the synergistic effects of the acrylic emulsion with a hard-inside soft-outside type core-shell structure and the carboxyl coated diatomite and nano-silica mixed particles are adopted, particularly, the carboxyl coated diatomite and nano-silica mixed particles achieve obvious effects, so that the stain resistance of the exterior wall emulsion paint can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of latex paint, in particular to a stain-resistant latex paint for exterior walls. 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] The purpose of the present i...
