Abstract

The invention relates to the technical field of hemp colored stone paint, and provides a preparation method of a hemp colored stone paint. The preparation method comprises the following steps: preparing a component A: mixing deionized water, a dispersing agent, a wetting agent and a defoaming agent together; adding titanium dioxide, kaolin and cellulose; adding a neutralizer, a preservative and propylene glycol; adding a first acrylic emulsion and a coalescing agent; adding a magnesium lithium silicate solution with the concentration of 8%; adding 90-mesh gravel; preparing a component B: mixing a first anti-settling agent solution with a magnesium lithium silicate solution; preparing a component C: stirring a second acrylic emulsion, and adding a second anti-settling agent solution with the concentration of 5%, a preservative, a cosolvent, a coalescing agent and deionized water in the stirring process; adding a compound thickening agent and a neutralizing agent; adding 70-mesh gravel, and adding a defoaming agent in the stirring process; and sequentially adding the prepared component B and the prepared component C into the component A. According to the preparation method of the hemp colored stone paint provided by the invention, the specific gravity of the prepared hemp colored stone paint is smaller.

Description

technical field [0001] The invention relates to the technical field of hemp-colored stone paint, in particular to a preparation method of hemp-colored stone paint. Background technique [0002] Both real stone paint and texture paint are made of emulsion and sandstone, with a very large specific gravity, generally up to 1.7g / L, which brings inconvenience to the transportation of workers during construction and brings negative pressure to the exterior wall . At the same time, natural colored sand ore resources are limited. In addition, the vicious competition in the market has been very fierce in recent years, resulting in the quality of real stone paint getting worse and worse, mainly in hiding power, weather resistance, and sand loss, which increases the waste of resources and is not easy to be widely used. Contents of the invention [0003] In view of the defects in the prior art, the purpose of the present invention is to provide a preparation method of hemp colored s...
