A kind of imitation stone paint and preparation method thereof

Abstract

The invention discloses a stone-like paint and a preparation method thereof, belonging to the technical field of paint. Its technical points are the following components in parts by weight: 600-700 parts of base paint; 100-200 parts of coating phase varnish; 100-300 parts of granulation solution; the base paint includes the following components in parts by weight: 200 parts of water ‑400 parts; 1.3‑5.2 parts of cellulose; 0.5‑1.5 parts of thickener; 30‑50 parts of protective glue; 1.8‑2.5 parts of defoamer; 3‑5 parts of dispersant; 1‑2 parts of wetting agent; 1-3 parts of preservative; 7-9 parts of titanium dioxide; 40-60 parts of kaolin; 140-160 parts of styrene emulsion; 6-10 parts of film-forming aid; ‑1 part; 2‑10 parts of toner; the protective glue includes lithium magnesium silicate and water, and the weight ratio of lithium magnesium silicate to water is (0.8‑1):10. It has the advantages of keeping the colorful particles, functional pigments and fillers and additives in the paint in a uniform dispersion state for a long time, and can form a uniform, clear and colorful imitation marble texture in one-time construction.

Description

A kind of imitation stone paint and preparation method thereof technical field The invention belongs to coating technical field, more specifically, it relates to a kind of imitation stone paint and preparation method thereof. Background technique [0002] The real stone paint is a kind of paint whose decorative effect resembles marble and granite. Mainly use natural stone of various colors It is formulated with powder and applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. Real stone paint is easy to construct, easy to dry and save time. The advantages of convenient construction and other advantages make real stone paint products the mainstream products in the current market. In the prior art, as disclosed in the Chinese invention patent that publication number is CN102391767A, a kind of high solid content inside and outside Cross-linked water-in-water colorful granite coating, including disperse phase, dispersion medi...

Problems solved by technology

[0004] However, during the construction of the real stone paint in the prior art, due to the colored sand grains of the raw material (the sand grains are too thick, it is easy to drop the sand in the spraying, which affects the construction dosage and cost, and the grain size is too fine and cannot well develop the flake texture effect of marble). Due to the restrictions on the use of natural stone, the texture and texture of natural stone cannot be perfectly displayed realistically. The texture and texture of natural stone are often achieved by multiple sprays. The final effect of such construction depends on the skills of the construction master, and even this cannot guarantee approval Consistent construction effect between times
