Color piece for building paint and preparing method

Abstract

The invention discloses a color sheet used for building coating. In the prior art, the color sheet is formed by mixing limestone powder filler coating or fine powder, such as heavy calcium carbonate, light calcium carbonate, or titanium dioxide filler, etc. into coating and then forming a film. The manufacturing efficiency of such color sheet or film is low and a plurality of procedures, such as coating, drying, knockout, crushing, etc. are needed, which consumes a lot of manpower, energy and time, has low output and high cost, and needs to consume a lot of organic materials. The invention directly dyes a basic diaphragm in appropriate specification into a film, dries the film, and then screens to obtain the color sheet. The color sheet of the invention effectively reduces the consumption of the film forming coating (the consumption of the film forming coating and color paste is less than 50 percent of the consumption of the traditional color sheet coating), saves the crushing procedure in the traditional preparation method, has 100 percent of color sheet yield, greatly improves the production efficiency, reduces the cost of the color sheet, has better water resistance, is not softened after being put in the coating for a long time, easy to be stored and transported.

Description

technical field [0001] The invention relates to a color flake for architectural paint, and also relates to a preparation method of the color flake. Background technique [0002] At present, building wall coatings are rich in varieties and colorful. Among them, the architectural coatings with imitation granite surface effects are especially favored by people, but the production of imitation granite architectural coatings needs to add color flakes. After adding color flakes, the decorative effect of the paint is very strong, and it has the performance effect of granite and is magnificent. At present, the production of color film is obtained by forming a film from a coating prepared by stone powder filler coating or fine powder such as double fly powder, light calcium carbonate, or titanium dioxide filler. Although this kind of color film can enhance the surface effect of imitation granite, it also has such disadvantages: that is, the efficiency of film formation is low, and i...
