A self-hardening film-forming architectural decorative porcelain-like coating and preparation method thereof

Abstract

The invention relates to a self-hardening film-forming building decoration ceramic simulating coating, and belongs to the field of building coatings. The self-hardening film-forming building decoration ceramic simulating coating provided by the invention is prepared from the following raw materials in parts by weight: 1 to 4 parts of nano-silicon oxide, 2 to 5 parts of nano-aluminium oxide, 3 to 5.8 parts of nano-bismuth oxide, 140 to 165 parts of silica sol, 3 to 3.8 parts of lithopone, 10 to 15 parts of light calcium carbonate, 1 to 7 parts of sodium pyrophosphate, 200 to 230 parts of a wollastonite powder, 0.1 to 0.5 part of cellulose ether and 40 to 65 parts of water. The self-hardening film-forming building decoration ceramic simulating coating prepared by the preparation method contains self-crystallizing nano-filler; the self-crystallizing nano filler grows automatically in the silica sol and is hardened to form a smooth hard coating which is excellent in water resistance and wear resistance.

Description

technical field [0001] The invention relates to a self-hardening and film-forming architectural decorative porcelain imitation paint, which belongs to the field of architectural paints. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. Imitation porcelain paint is a kind of commonly used architectural paint. Porcelain-like paint, also known as enamel paint, is a kind of architectural paint whose decorative effect is similar to enamel finish. Porcelain-like coatings are widely used. It can be painted and sprayed on solid surfaces such as cement surfaces, metal surfaces, plastic surfaces, and wood. It can be used for anticorrosion of electrical appliances, machinery and furniture exterior decoration, and can also be used for interior walls of public buildings, interior walls of residences, kitchens, toilets, and ba...

AI Technical Summary

Problems solved by technology

Since the composition has hygroscopicity to varying degrees, and the fillers are dispersed in separate forms, the coating after film formation has weak water resistance. Once stains are stained, they will quickly penetrate into the inner layer of the coating film, making it difficult to clean. , it is difficult to achieve the performance of ceramic

Moreover, the hardness and wear resistance of existing imitation porcelain coatings are far from those of ceramics.
