Problems solved by technology

Although there are more and more water-based crack paint products on the market now, most of the crack material products are single-layer paint, and the product effect is mainly based on the color contrast to produce cracking effects, and the concave-convex three-dimensional effect is not strong.
In addition, the vast majority of water-based paints still have the following problems: first, the paint needs to be used within 2-4 hours after use, otherwise it will deteriorate; Cracking, some cracking is too large; third, the paint has poor stability after curing on the surface of the substrate, it is easy to peel off, and is not durable

Abstract

The invention discloses water-based crack sandstone paint and a preparation method thereof. Water-soluble resin, nano calcium carbonate powder and titanium white are added into deionized water firstly, dispersing at high speed is carried out, then elastic emulsion, hydroxyethylcellulose, auxiliary material and residual deionized water are added, and dispersing at medium speed is carried out to obtain priming coat composition; and another container is taken, deionized water is added, firstly the auxiliary material is added under the condition of low-speed stirring, and acrylic resin, quartz sand, the nano calcium carbonate powder, the titanium white, the elastic emulsion and the hydroxyethylcellulose are continuously added under the condition of low-speed stirring, thus a top coat composition is prepared. The paint disclosed by the invention has the advantages of good stability, reusability, use convenience and the like; no cracking or irregular cracking is not caused after the paint disclosed by the invention is coated onto base material; and the paint disclosed by the invention can be well adhered onto the surface of the base material, and the paint is waterproof, durable and resistant to scrubbing.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a water-based cracked sandstone coating and a preparation method thereof. Background technique [0002] Paint, traditionally called paint in China, is a solid film that can be coated on the surface of an object by different construction techniques to form a solid adhesion, certain strength, and continuity. There are three main functions of traditional coatings: protection, decoration and concealment of product defects. With the development of the industry and the improvement of people's demand for use, people have higher and higher requirements for the decorative function of coatings. Crackle paint came into being as the times require. [0003] Crackle paint, that is, it can produce cracks after being painted on the surface of the wall. It has an elegant aesthetic feeling and belongs to the art type paint. High-end decorative craft works. Although there are mor...
