High-performance sand wall coating and preparation method thereof

Abstract

The invention relates to a high-performance sand wall paint and a preparation method thereof, which is characterized in that it comprises the following raw materials in parts by weight: 15-30 parts of base material, 60-80 parts of natural colored sand, and 3-6 parts of film-forming aid , 0.1-0.5 parts of wetting agent, 0.5-2 parts of titanium dioxide, 0.1-0.3 parts of dispersant, 0.1-0.5 parts of anti-corrosion and anti-mold agent, 0.1-0.5 parts of multi-functional additives, 0.05-0.2 parts of defoaming agent, 0.01-0.2 parts of thickener, 10-15 parts of deionized water, the base material includes a mixture of pure acrylic emulsion and styrene-acrylic emulsion, and the weight ratio of pure acrylic emulsion and styrene-acrylic emulsion is 1-2:1. The components of the sand wall-shaped paint of the present invention are scientifically compatible, and the prepared paint has good comprehensive performance, less dosage, low use cost, high strength, compact surface, convenient construction, good stain resistance, high mechanical construction efficiency, and coating decoration The effect is good, the texture is strong, the color is rich, and the imitation stone effect is good.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-performance sand-wall-like coating suitable for the coating of exterior walls of houses, schools, apartments, etc. and a preparation method thereof. Background technique [0002] Sand wall-like coatings are widely used in decorative walls due to their vivid and bright colors and excellent decorative effects. Due to its considerable market value and high popularity, the development and application of sand wall coatings have also been continuously innovated for a long time. Through the construction skills of engineering personnel, various artistic effects can be created, and the demand for sand wall-like coatings is increasing day by day. [0003] At present, most of the sand wall-shaped paints on the market use natural colored sand, artificial glossy colored sand or calcined colored sand to achieve the effect of sand wall-like stone-like paint textur...

AI Technical Summary

Problems solved by technology

However, there are following defects in the sand wall-like coating made of the above materials: 1. Due to the high gloss, the coloring power and hiding power of natural colored sand are low, and even part of the colored sand is transparent, which makes the coating easy to refract light and bloom, and the dosage must be large In order to ensure complete coverage of the base layer, the cost of use is high; 2. Due to the use of organic emulsion as the middle coating, the coating is prone to whitening, gloss, poor stain resistance, and complicated construction technology; 3. Organic materials such as cellulose are used As a thickener, the coating is easy to absorb water and whiten, has good leveling property and is not easy to shape, slow drying speed, low viscosity in spraying application, weak covering power of coating film, low mechanical construction efficiency, easy sand falling, and poor durability.
