Environment friendly dry powder emulsion paint and preparation method thereof

Abstract

The invention provides environment friendly dry powder emulsion paint and a preparation method thereof. The environment friendly dry powder emulsion paint comprises the following substances in percentage by weight: 10-45% of white cement, 0.35-0.65% of cellulose ether, 40-75% of calcium carbonate, 3-25% of ash calcium, 0.1-0.5% of cassava modified starch, 0.1-2% of wood fiber, 0.1-1% of fluorescent whitening agent, 0-25% of redispersible emulsion powder, 0-30% of titanium white and 0-5% of inorganic pigment. The preparation method comprises the following steps: putting the substances in percentage into a blender, evenly mixing and packaging to obtain the finished product; adding water and evenly stirring for using; and realizing one-step forming from bottom to surface. The invention has the advantages of high strength, small possibility of cracking, no drop, no peeling, no hollowing, easy color, bright color, small possibility of color fading, scrubbing resistance, mildew resistance, environmental protection, non-pollution, low cost, simple and easy packaging, convenient transportation, simple construction and the like, and can be widely applied to decoration of interior and exterior walls of the buildings.

Description

technical field [0001] The invention belongs to the field of dry powder coatings, in particular to a dry powder latex paint and a preparation method thereof. Background technique [0002] The solvent-based latex paint used in building decoration in the market is liquid, which is not convenient for packaging, transportation and storage. Storage and use of liquid latex paint requires a large number of plastic or iron storage tanks. These storage tanks are expensive and waste resources. polluted environment. [0003] During the construction of the existing latex paint, the whole process requires 5 processes. First, the putty is applied twice, and then the edges and corners are smoothed with sandpaper, and then the primer is applied again, and finally the top coat is applied again. The process is cumbersome, labor-intensive, time-consuming, and Fee material, higher cost. After construction, the coating is easily affected by the quality of the putty powder. If the quality of th...

[0003] During the construction of the existing latex paint, the whole process requires 5 processes. First, the putty is applied twice, and then the edges and corners are smoothed with sandpaper, and then the primer is applied again, and finally the top coat is applied again. The process is cumbersome, labor-intensive, time-consuming, and Fees, high cost

After construction, the coating is easily affected by the quality of the putty powder. If the quality of the putty is unstable, the coating will fall off, peel, hollow, and sometimes fade, which will affect the appearance. In severe cases, it is necessary to remove all the bottom layer and re-apply

[0004] The Chinese patent application document with the application number 200610036625.9 discloses an environment-friendly dry powder coating and its preparation method. The whiteness of the white cement and bentonite in this coating formula has limitations, so the whiteness is insufficient and affects the appearance; Insufficient strength makes it difficult to color, and the color is difficult to achieve the design effect; because this kind of paint does not contain anti-cracking materials, when there are fine cracks in the wall, the coating will also crack; and because the paint contains diatomaceous earth , and diatomaceous earth has a porous particle structure, which makes the surface coating highly rough. If it is required to make a porcelain surface on the surface of the coating, it is difficult to achieve
