Water-based frosted imitation stone paint, and thermal insulation and decoration integrated plate using the same

Abstract

The invention discloses a water-based frosted imitation stone paint. The water-based frosted imitation stone paint comprises a sand-containing base paint, a continuous phase and a protective glue solution according to a mass ratio of (20-22):(50-55):(25-28), wherein the sand-containing base paint comprises, by mass, 45-50 parts of quartz sands, 30-35 parts of deionized water, 0.6-0.8 part of hydroxyethyl cellulose ether, 0.2-0.3 part of a defoamer, 0.5-1 part of propylene glycol, 0.1-0.2 part of a pH adjuster, 0.5-0.7 part of a film-forming aid, 0.2-0.3 part of a preservative, 12-15 parts of asilicon-acrylic emulsion, 0.1-0.2 part of a rheological additive and 0.1-0.2 part of a color stabilizer. The invention also discloses a thermal insulation and decoration integrated plate. The decorative layer of the plate is coated with the imitation stone paint. The imitation stone paint can obtain the effect and hand feeling of wool surface-like stones through one-time spraying construction, sothe construction process is simplified, the efficiency is increased, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a water-based frosted stone-like varnish and a thermal insulation and decorative integrated board using the varnish. Background technique [0002] Compared with the traditional external thermal insulation system for building exterior walls, the thermal insulation and decoration integrated board integrates thermal insulation, energy saving and decorative functions. , decoration and protection” wall energy-saving and thermal insulation construction system, which can effectively avoid the shortcomings of traditional external wall thermal insulation systems such as low construction efficiency and easy cracking. As the fastest-growing wall insulation and decoration material in recent years, the thermal insulation and decoration integrated board has excellent characteristics: light weight and high strength, thermal insulation, fire and flame retardant, multiple decoration effects,...

AI Technical Summary

Problems solved by technology

[0003] There are many decorative effects of thermal insulation and decorative integrated boards. The most popular is the colorful imitation stone effect that can highly simulate and simulate granite patterns, and can be divided into bright and matte. However, latex paint is generally used as the matching base color. The paint is sprayed on the base coat of the same color. After the film is formed, the flatness of the multi-color particles is better, and the overall coating lacks a three-dimensional effect. It is often used to imitate the effect of smooth stone materials; After the color particles are formed into a film, there is a slight concave-convex feeling, but it seems that the color particles are completely "floating" on the same color base, and the degree of fusion with the same color base in terms of color and effect is too poor, which makes the overall simulation of the coating great. Discount, and because both the primer and the colorful imitation stone paint belong to the category of "latex paint", although the color particles can produce a slight concave-convex feeling, it cannot show the "frosted" feel effect of the rough stone.

At present, if you want to imitate the effect of rough surface stone, you need to use real stone paint or texture paint as the middle coating to show the "frosted" effect of rough surface stone, and then spray colorful imitation stone paint on it to show the pattern effect of granite, so The construction process of the coating in the construction is increased, which brings problems such as complicated process, low efficiency and high cost.
