Embodiment 1

[0035] Raw Material Compatibility The present invention is composed of solid paints with different colors and water. The weight ratio range of each component is: cellulose 3kg, polyvinyl alcohol 6.5kg, white latex 6.5kg, titanium dioxide 5kg, talcum powder 3kg, lithopone 1kg, glycerin 1kg, ethylene glycol 1kg, calcium carbonate 1kg, Sodium hexametaphosphate 1kg, defoamer 0.5kg, antifungal agent 0.5kg, pigment ≤ 0.1kg, purified water to 100kg.

[0036] In the above formula, the cellulose can use acid and alkali-resistant methyl cellulose, white latex as a binder, titanium dioxide, talcum powder, lithopone and light calcium carbonate as solid fillers, and glycerin, Ethylene glycol and sodium hexametaphosphate are used as thickener, antifreeze and dispersant respectively.

Embodiment 2

[0038] Preparation method of the present invention

[0039] 1. Put the above materials in a plastic container and stir them manually, then add water while stirring, after stirring evenly, divide them into several barrels (depending on the required color), and put them in each barrel as needed Add the required paint color paste for coloring, and further mix it with a colloid mill to prepare for granulation.

[0040] 2. Preparation of dispersion liquid: Weigh aluminum sulfate with 5% of the total mass of the liquid, add it to the stirring tank and add water for stirring, use ammonium aluminum sulfate to adjust the acidity of the solution until the pH of the solution is less than 5.

[0041] 3. Granulation: Use a nozzle with several small holes to spray the color paste to be granulated into the dispersion solution in the stirring tank under pressure, and stir at the same time. The stirring speed can be adjusted according to the length of the strips required .

[0042] 4. Filter...

Embodiment 3

[0045] Coating method of the present invention

[0046] In addition to thin coating tools, tools should also be equipped with air compressors and special spray guns for colorful paints. The pressure of the air compressor is 0.2MPa to 0.8MPa, and the displacement is ≥0.25M 3 / min, considering the convenience of movement and use, 220V small models can be used.

[0047] The painting method of the present invention is composed of base treatment, batch scraping of putty, brushing of back cover paint, brushing of intermediate paint, and spraying of colorful paint surface layer.

[0048] The main points of painting of the present invention, except the surface layer spraying of colorful paint, other processes are similar to the painting of general indoor metope, and the difference is to brush the back cover paint and the middle paint, generally these two kinds of paints are best selected and colorful Coatings that match the paint surface. The spraying of the colorful paint surface ...

Abstract

The invention provides a solid state strip-type waterborne multicolor coating and a preparation method and coating method thereof; the coating mainly comprises cellulose, polyvinyl alcohol, white latex, titanium dioxide, talcum powder, lithopone powder, glycerol, ethylene glycol, calcium carbonate, sodium hexametaphosphate and pure water, etc.; after formulating, granulating, packaging and other procedures, the coating is prepared and coated through base processing, putty scraping, bottom coating brushing, medium coating brushing and multicolor coating surface spraying. The invention is rich in color, and convenient in operation, with strong stereoscopic decorative effect achieved by one step spraying.

Description

technical field [0001] The invention relates to a paint, a preparation method and a coating method thereof, more specifically, a solid strip water-based multicolor paint, a preparation method and a coating method thereof. Background technique [0002] Generally, paint is a paint in which colored particles containing organic solvents are dispersed in water. Due to the presence of organic solvents, the film will cause indoor air pollution. Contents of the invention [0003] The purpose of the present invention is to provide a kind of all-water-based colorful coating, it is the coating that reaction curing type emulsion is dispersed in water, and it is to disperse the colored pigment of sulfur hydration treatment in the cross-linking agent of high reaction control to adjust cross-linking density A linked colored gel is formed, so that the colored pigments will not be precipitated in water, the hue of various colored particles remains unchanged, and the total volatile organic ...
