A kind of environment-friendly dry powder latex paint and preparation method thereof

Abstract

An environment-friendly dry powder latex paint and a preparation method thereof. The environment-friendly dry powder latex paint is composed of the following substances in weight percent: 10-45% of white cement, 0.35-0.65% of cellulose ether, 40-75% of calcium carbonate, gray calcium 3-25%, cassava modified starch 0.1-0.5%, wood fiber 0.1-2%, fluorescent whitening agent 0.1-1%, redispersible latex powder 0-25%, titanium dioxide 0-30%, inorganic pigment 0 ~5%, the above-mentioned components are put into the mixer according to the percentage, and the finished product can be obtained after mixing evenly and then packaged. After adding water and stirring evenly, it can be used. It is formed from the bottom to the surface at one time. The invention has high strength, is not easy to crack, and does not Shedding, no peeling, no hollowing, easy coloring, bright colors, not easy to fade, scrub resistance, mildew resistance, environmental protection and pollution-free, low cost, simple packaging, convenient transportation, simple construction, etc., can be widely used inside and outside buildings Wall decoration.

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...

[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
