Water-based crack art coating and preparation method thereof

Abstract

The invention relates to a water-based crack art coating and a preparation method thereof, and the water-based crack art coating comprises a crack primer and a crack finish which are matched for use, the crack primer is mainly prepared from the following components in parts by weight: water, a water-based dispersing agent, a water-based wetting agent, a water-based defoaming agent, white carbon black, talcum powder, mica powder, a silane coupling agent, a polyacrylic acid emulsion, an anti-freezing agent, a coalescing agent, a preservative, water-based color paste and a water-based thickening agent. The defects that an existing solvent type crackle coating is not environmentally friendly, high in construction difficulty and the like are overcome, the polyacrylic acid emulsion and the pure acrylic emulsion are selected respectively, wollastonite, white carbon black, hollow covering polymer microspheres, barium sulfate and other pigments and fillers are combined, the materials are applied to a water-based coating system through optimization of a dispersion system, and the water-based crackle coating is prepared. After the crack primer and the crack finish are matched for use, the crack primer and the crack finish have rich crack effects and have the advantages of being environmentally friendly, easy to construct, good in water resistance and chemical stability and long in service life.

Description

technical field [0001] The invention relates to a water-based crack art paint and a preparation method thereof, which are applied in the field of art paint. Background technique [0002] Crack paint is a kind of artistic paint with special decorative effect. It is often used in handicrafts, architectural decoration and home decoration. With special colors, it can achieve decorative effects such as antiques. In the application of building interior walls, crack coatings can form natural crack patterns after construction. According to the construction process, construction environment conditions and formula color matching, the crack effect patterns are various, and as an artistic coating, it has its unique visual effect. In recent years, with the personalized pursuit of products and home decoration by art paint consumers, water-based crack coatings have also been gradually developed and applied. [0003] At present, the traditional crack coatings on the market are mainly solve...

Problems solved by technology

[0009] In order to overcome the disadvantages of the existing solvent-based crack paints such as unenvironmental protection, high difficulty in construction, great influence of the process on the product effect, and unfavorable for large-scale construction, the present invention provides a water-based crack art paint and a preparation method thereof, respectively using polyacrylic acid Emulsion and pure acrylic emulsion, combined with pigments and fillers such as wollastonite, white carbon black, hollow covering polymer microspheres and barium sulfate, were applied to the water-based coating system through the optimization of the dispersion system, and the crack primer and crack surface were prepared. The lacquer has a rich crack effect after being used together, and has the advantages of low VOC, environmental protection and natural and unique artistic effects. It is also easy to construct, has good water resistance and chemical stability, and has a long service life. It is suitable for building interior wall decoration applications
