Novel dry powder emulsion paint

Abstract

The invention discloses novel dry powder emulsion paint. The novel dry powder emulsion paint consists of the flowing substances in percentage by weight: 5 to 50 percent of white cement, 0.3 to 1 percent of cellulose ether, 35 to 75 percent of calcium carbonate, 0 to 30 percent of sierozem, and 0 to 10 percent of inorganic or organic pigment. All the substances are fed into a stirrer in a weight ratio, mixed uniformly and packaged to form a finished product; and water is added into the finished product so as to obtain a mixture which can used after being stirred uniformly, and the mixture is formed from bottom to top at one time. The novel dry powder emulsion paint has the characteristics of high intensity, bright color, scrubbing resistance, mould proofing, low cost, simple package, and convenience in transportation, is not easy to crack and construct, does not fall and pollute environment and can be widely applied to decoration of inner and outer walls of buildings; scale and hollowing are avoided; and by using paint, the wall can be dyed easily, and the color is not easy to fade.

Description

technical field [0001] The invention belongs to the field of 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 the putty is ...

[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 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 application number 200610036625.9 discloses a new type of dry powder coating and its preparation method. The whiteness of white cement and bentonite in this coating formula has limitations, so the whiteness is insufficient, which affects the appearance; the insufficient whiteness makes It is not easy to color, and the color is difficult to achieve the design effect; and because the coating contains diatomite, and diatomite has a porous particle structure, the surface coating is highly rough. If it is required to make a porcelain surface on the surface of the coating, it is difficult to achieve
