Problems solved by technology

However, since the dispersed phase and the dispersed medium of the water-based colorful paint are all composed of water-based substances, it is difficult to solve the stability of the dispersed phase and the dispersed medium and their coexistence.
[0004] Moreover, the storage performance of the existing granite coatings is difficult to achieve no thickening after half a year, and problems such as cross-coloring and bleeding often occur, and the water resistance of the existing granite coatings only meets or slightly exceeds the national standard 96 hours without exception standard, its weather resistance time is short
Moreover, it is difficult to ensure the stability of the particles produced by the existing granite coating after being stirred and sieved in a conventional way.

Embodiment 1

[0036] First, prepare a colloidal solution: mix 97% deionized water and 3% silicate colloid evenly to make a colloidal solution.

[0037] Secondly, prepare the white paint, and the white paint is configured according to the following components: 49.7% of water, 1.3% of cellulose thickener, 1.2% of sodium salt dispersant, 0.3% of mineral oil defoamer, 3% of Titanium dioxide, 7% kaolin and 4.5% calcium carbonate are added to the mixer in turn and stirred evenly. When the dispersion reaches a fineness of 60, add 30% styrene-acrylic emulsion, 2.2% dipropylene glycol methyl ether, and 0.5% antiseptic agent, 0.3% compound defoamer. During the addition of all the above components, the fineness must reach 60.

[0038] In the formula of the above-mentioned white paint, an emulsion with a lower TG value and better adhesion is selected; preferably styrene-acrylic emulsion. The dispersant is an inorganic dispersant, preferably sodium pyrophosphate, which can reduce the viscosity of the ...

Embodiment 2

[0044] First, prepare a colloidal solution: use 97% deionized water and 3% silicic acid colloid to mix evenly to make a colloidal solution.

[0045] Secondly, the white paint is prepared, and the white paint is configured according to the following components: 48.5% of water, 1% of cellulose thickener, 1.2% of sodium salt dispersant, 0.3% of mineral oil defoamer, 3% of Titanium dioxide, 4% kaolin and 4% calcium carbonate are added to the mixer in turn and stirred evenly. When the dispersion reaches 60, then add 30% styrene-acrylic emulsion, 2.2% dipropylene glycol methyl ether, and 0.5% bactericidal Preservatives, 0.3% compound defoamer, 5% colloidal solution. During the addition of all the above components, the fineness must reach 60.

[0046] Again, prepare base paints of various colors. In the present embodiment, the white paint adopts 98%, and the color paste of other colors adopts 2%. The color paste is preferably an organic pigment, and the color paste is further subdi...

Embodiment 3

[0049] First, prepare a colloidal solution: mix evenly with 90% deionized water and 10% silicic acid colloid to make a colloidal solution.

[0050]Secondly, prepare the white paint, and the white paint is configured according to the following components: 40% of water, 1% of cellulose thickener, 1.2% of sodium salt dispersant, 0.3% of mineral oil defoamer, 3% of Titanium dioxide, 7% kaolin and 4.5% calcium carbonate were added to the mixer in turn and stirred evenly. When the dispersion reached a fineness of 60, 30% styrene-acrylic emulsion, 2.2% dipropylene glycol methyl ether, and 0.5% bactericidal Preservatives, 0.3% compound defoamer, 10% colloidal solution. During the addition of all the above components, the fineness must reach 60.

[0051] Again, prepare base paints of various colors. White paint adopts 92% in the present embodiment, and the color paste of other colors adopts 8%, and this color paste is preferably organic pigment, and this color paste is subdivided int...

Abstract

The invention relates to a coating, in particular to a weather-resistant liquid-state granite coating which can solve the defects that the storage performance is very difficult to have no back thickening above half a year, and color contamination, color bleeding and other problems, which are difficult to solve at prevent, occur often. The coating mainly comprises 30%-45% of colloidal solution, 25%-40% of base paint in various colors and 15%-30% of emulsion. The weather-resistant liquid-state granite coating has the advantages of no back thickening above half the year, no color contamination, no color bleeding, water resistance, long weather-resistant time, stable granules and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a weather-resistant liquid granite coating. Background technique [0002] Granite is a natural stone with hard texture, rich texture, good durability, and gorgeous and noble decorative effect. It has become a commonly used material in high-end decoration projects. However, excessive mining of granite will cause water and soil erosion, which is not conducive to the protection of the ecological environment; after cutting, transportation, installation and other processes, the overall cost is expensive; as an exterior decoration material, its construction is more complicated, which increases the load bearing of the wall, and there are many disadvantages. Safety factors, and the seams are easy to hide dirt and water, which affects the appearance; some granite stones also release traces of radioactive elements, which are harmful to human health. Many of the above factors have limited its application. Peo...
