Sand-in-sand stone-like coating and preparation method thereof

Abstract

The invention relates to a sand-in-sand stone-like coating. The sand-in-sand stone-like coating comprises water, a bactericide, a powdery thickener, a dispersing agent, a defoaming agent, a coalescingagent, propylene glycol, a pH regulator, a film forming matter, a liquid thickener, sintered color sand, a cross-linking agent and a protective adhesive. According to the sand-in-sand stone-like coating provided by the invention, the strength of color points is improved, and a ceramic color stone coating and a sand-in-water coating are combined into a whole. The sand-in-sand stone-like coating prepared by a method disclosed in the invention is formed by batch coating once. The sand-in-sand stone-like coating retains flatness of the ceramic color stone coating, maintains color diversity of thesand-in-water coating, and is shortened in a construction period.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a sand-in-sand imitation stone coating and a preparation method thereof. Background technique [0002] At present, stone-like coatings are one of the main products of architectural exterior wall coating manufacturers, including real stone paint, rock flake real stone paint, water-based colorful paint and other products. These products have realistic stone-like effects, good decorative effects, good crack resistance, Good durability and other characteristics. Compared with natural stone, it has the characteristics of low cost, small wall load-bearing, easy renovation and maintenance, etc. However, the conventional stone-like coatings have the following problems in production and use: 1. Since the color points in the sand-in-water are toned by colorants, some organic colorants, such as phthalocyanine blue, scarlet, lemon yellow, etc., have poor aging resistance , resulting in poor aging r...

AI Technical Summary

Problems solved by technology

However, the conventional stone-like coatings have the following problems in production and use: 1. Since the color points in the sand-in-water are toned by colorants, some organic colorants, such as phthalocyanine blue, scarlet, lemon yellow, etc., have poor aging resistance , leading to poor aging resistance of sand-in-water coatings and easy fading

2. Sand-in-water, water-in-water, and sand-in-water sprayed twice, due to the cumbersome construction process, the construction period is long

3. Real stone paint has problems such as high construction consumption, poor simulation, easy to accumulate dust, poor stain resistance, and low bonding strength.

4. The commercially available sand-in-sand imitation stone paint is only suitable for spraying and cannot be scratched due to the insufficient color point strength of the dispersed phase.

CN109777223A discloses a colorful imitation stone paint and its preparation method. The paint prepared by the preparation method provided by it can solve the problem that the existing colorful stone imitation paint needs to use real stone paint as the middle coat, and there are cracks due to the matching difference between the paints. , peeling and other technical problems

But above-mentioned disclosed coating still can't all solve above-mentioned problem
