AI Technical Summary

Technical Problem

Inorganic stone paint suffers from poor initial water resistance and whitening, poor spray atomization and anti-splatter performance, and poor system compatibility, resulting in a high sand shedding rate during construction, which limits its application in old building renovation and urban renewal.

Method used

A compound of three film-forming materials—cyclosiloxane monomer-modified styrene-acrylic emulsion, epoxy-modified silica, and methacryloyloxy-modified silica—is used. Through chemical graft copolymerization, the hydrophobicity of the emulsion is enhanced, its compatibility is improved, and its spray application performance is enhanced.

Benefits of technology

It improves the initial water spraying resistance, water whitening resistance, spray atomization efficiency, and anti-splatter properties of inorganic stone paint, reduces sand shedding rate, and enhances the storage stability and application performance of the paint.

Abstract

The invention relates to a silicon modified inorganic stone-like coating and a preparation method thereof, and the silicon modified inorganic stone-like coating is mainly prepared from the following components in parts by weight: 10-20 parts of cyclosiloxane monomer modified styrene-acrylic emulsion, 1-10 parts of epoxy modified silicon dioxide, 0.02-1 part of methacryloyloxy modified silicon dioxide, 1-5 parts of a silane coupling agent, 1-5 parts of a silane coupling agent, 1-5 parts of a silane coupling agent, 1-5 parts of a silane coupling agent, and the balance of water. The water-based paint is prepared from the following components in parts by weight: 0.02 to 0.5 part of glyoxal modified hydroxyethyl cellulose ether, 60 to 75 parts of colored sand, 0.02 to 0.5 part of ammonia water, 0.2 to 1 part of coalescing agent, 0.2 to 1 part of antifreezing agent, 0.02 to 0.5 part of thickening agent, 0.02 to 0.5 part of defoaming agent, 0.02 to 0.5 part of sterilizing agent and 7.85 to 13.48 parts of water. The silicon-modified inorganic stone-like paint has the advantages of excellent initial stage water spraying white resistance, storage stability, high spraying atomization efficiency, good splashing resistance and low sand falling rate, and can be widely applied to old house transformation and city rejuvenation.
