Imitation stone matte rock flake paint for building exterior wall coating and preparation method thereof

Abstract

The invention discloses an imitating stone matte rock slice varnish for construction exterior wall painting and a preparation method thereof. The imitating stone matte rock slice varnish for construction exterior wall painting is prepared from 25 to 40 parts of water, 0.1 to 0.2 part of wetting agent, 0.25 to 0.4 part of defoaming agent, 0.1 to 0.3 part of multi-functional agent, 1.5 to 6 parts of coalescing agent, 30 to 50 parts of emulsion, 2 to 8 parts of three-dimensional porous nano-silicon dioxide, 20 to 35 parts of natural rock slices, 1.5 to 4 parts of thickening agent, and 0.1 to 0.3 part of antibacterial preservative. The three-dimensional porous nano-silicon dioxide is obtained through the following method comprising the steps of reacting a triblock copolymer P123, tetraethyl orthosilicate and cyclohexane at a certain temperature under an acid condition, filtering, washing, drying, and roasting to obtain the three-dimensional porous nano-silicon dioxide. The natural rock slice varnish provided by the invention is realistic in stone imitating effect, simple in production process, and excellent in product performance, and has high weather resistance with a matte characteristic. The three-dimensional nano SiO2 synthesized by the invention is used as a matting agent so as to be applied in a natural rock slice varnish coating, so that the imitating stone matte rock slice varnish achieves a matte realistic effect, and is easy to apply in marble pillars, windowsills, eave corners, sculptures and the like, obvious in effect, and simple in construction process.

Description

technical field [0001] The invention relates to the technical field of decorative paints, more specifically, the invention relates to a stone-like matt rock flake paint for building exterior wall coating and a preparation method thereof. Background technique [0002] At present, the world's coating industry is developing rapidly, and new exterior wall coatings are also emerging in an endless stream. Traditional low-end products such as real stone paint and latex paint have gradually withdrawn from the market for mid-to-high-end exterior wall coatings. Functional, realistic simulation effects and matte Special coatings are more and more sought after by people, which can meet people's requirements for high-quality buildings. Due to the high price and heavy quality of granite stones, and the country expressly prohibits the use of granite stones in high-rise buildings, low-cost and high-quality imitation granite coatings have the advantage of being able to replace granite stones...

AI Technical Summary

Problems solved by technology

Chinese invention patent CN 101250345 B discloses a preparation method of natural rock flake paint. The natural rock flake paint prepared by the invention has a lifelike stone imitation effect after being painted, but it uses many raw materials and the preparation process is complicated. The method uses artificially synthesized rock flake as filler. Heavy weight, poor weather resistance and water resistance, strong mirror effect after adding finish paint

Patent CN 103045040 A also discloses a rock flake paint with natural mica flakes as a filler, but this invention uses more raw materials, and the production cycle is longer. Due to the strong mirror effect, it is easy to cause the aging rate of the paint to be accelerated and the service life to be shortened.
