AI Technical Summary

Technical Problem

Existing clear topcoat coatings for interior wall textured paints have defects in terms of inconsistent gloss and water resistance. Traditional matting technology affects storage stability and transparency, resulting in uneven gloss and a tendency to develop spots.

Method used

By using two different particle sizes of latex particles to form an uneven paint film surface during the film-forming process, and through the segmented reaction of the emulsion and nano-surface modification technology, combined with polymer/inorganic nanomaterial composite additives, a fully matte effect is achieved, avoiding the use of matting powder.

Benefits of technology

It improves the water resistance and storage performance of the coating, reduces the problem of inconsistent gloss, achieves a matte effect from all angles, enhances the transparency and application consistency of the coating, and avoids the defects caused by traditional matte powders.

Abstract

This invention relates to a fully matte, high-transparency topcoat varnish for interior wall textured coatings, its preparation method, and its application. The fully matte, high-transparency topcoat varnish comprises: an emulsion, a multifunctional additive, a thickener, a defoamer, a pH adjuster, a film-forming aid, an antifreeze agent, a dry film antifungal and anti-algae agent, a bactericide, and water. The emulsion is a silicone-modified pure acrylic mixed emulsion with a solid content of 36±1%, comprising coarse-particle-size emulsion and fine-particle-size emulsion. This invention utilizes two or more latex particles of different sizes to achieve an uneven surface on the paint film during film formation, thus achieving a matte effect. The prepared matte varnishes can reduce the risk of paint delamination and the potential for inconsistent gloss during use. Water resistance and storage performance are also significantly improved, greatly expanding its application in water-based multicolor coatings and interior wall art coatings.
