Problems solved by technology

The coating prepared by this method has the effect of polyester artificial marble after use. The preparation method is relatively simple and the application range is wide, but the cost is relatively high and the hardness is not enough. Although the cement can reduce the cost, the corrosion resistance is poor. Inconsistent luminosity, decorative effect needs to be improved

Abstract

The invention discloses a method for preparing waterborne granite coating, which is characterized in that the method comprises the following steps: firstly, preparing a color slurry, selecting a mastic coating prepared from high-quality pure acrylic or silicone acrylic emulsion, concocting to desired color, knife-coating the mastic coating on color strip cloth on a demolding machine at a desired thickness of 0.5 to 0.8 mm by a special coating machine, air-drying or oven-drying, peeling the paint film, and crushing to color sheets with desired size by a crusher; selecting additives such as water, dispersant, pH adjuster and anti-mould germicide for later use, and dispersing the color sheets in water under high-speed stirring to form nonuniform color slurries with different sizes; and uniformly mixing the color slurries with different colors 15 to 40 percent, pure acrylic emulsion 20 to 60 percent, quartz sand 0 to 60 percent and additives 0.5 to 2 percent according to the ratio to obtain the waterborne granite coating. The waterborne granite coating has the advantages of good decorative effect, safe operation, environment-friendliness, etc.

Description
