Ceramic simulating coating and preparing method thereof

Abstract

The invention provides a ceramic simulating coating and a preparing method thereof. The preparing method comprises the following steps: 1, dissolving hydroxypropyl cellulose in water with the temperature of 100 DEG C, soaking for 20-30 minutes, and then dissolving in cold water for dissolving; putting for standby application after the hydroxypropyl cellulose is fully dissolved into liquid, and needing to stir; 2, dissolving polyacrylamide YSA-40 and an auxiliary in warm water with the temperature of 75-85 DEG C, and after the polyacrylamide YSA-40 and the auxiliary are fully dissolved, putting for standby application; 3, filling a mixing tank with a glue solution obtained in step 1, then filling running water, filtering and then pouring the used auxiliary into the mixing tank during water filling, and mixing for 10 minutes; then adding the solution obtained in step 2, and mixing for 15 minutes; 4, finally and sequentially adding ash calcium powder, talcum powder, heavy calcium carbonate powder and zinc dioxide powder, and mixing until no granules are left; 5, discharging out of the tank, grinding and bagging to obtain the finished product. The ceramic simulating coating has the characteristics of good fineness, high covering rate, high viscosity, high hardness, strong covering power, no toxin or smell, hood acid resistance and alkali resistance, no color loss, fading, cracking or peeling phenomena after painting, easiness in construction, deterioration resistance, high temperature resistance and the like.

Description

technical field [0001] The invention relates to a paint, in particular to a porcelain-like paint and a preparation method thereof. Background technique [0002] 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 in the interior walls of public buildings, the interior walls of houses, kitchens, toilets, and bathroom joints. It can also be used for anticorrosion of electrical appliances, machinery and furniture exterior decoration. [0003] Imitation porcelain coatings are divided into the following two categories: [0004] The main film-forming substances of solvent-based resins are solvent-based resins, including two-component polyurethane resins cross-linked and cured at room temperature, two-component acrylic-polyurethane resins, one-component silicone-modified acrylic resins, etc., and pigments, solvents, etc. Porcelain white, light blue, milk yello...

AI Technical Summary

Problems solved by technology

Due to the use of scraping and smearing, the coating film is hard and dense, and has a certain degree of adhesion to the base layer. Generally, it will not bulge or foam. If an appropriate varnish is applied on it, the pollution resistance and other properties will be improved. There is improvement, the coating film of this kind of coating is thicker, not water-resistant, the performance is poor, the construction is more troublesome, the color is single, and the decoration is general

[0006] The fineness and covering rate of the imitation porcelain paint in the prior art are poor; the viscosity and hardness are not ideal; the covering power is not strong; the acid and alkali resistance is weak; it is easy to fade, fade, crack and peel after scraping; it is difficult to construct , easy to deteriorate, high temperature difference
