Problems solved by technology

Therefore, the durability, weather resistance and other performances of the existing water-in-water multicolor coatings are all determined by the performance of the polymer emulsion of organic materials, resulting in poor durability and weather resistance, and its artificial weather aging resistance time is only 1000h. Compared with the service life of the building > 50 years, it is too different

Abstract

The invention discloses a cement-based water-in-water multicolor paint which is composed of cement primary color granular slurry and protective slurry; and the cement primary color granular slurry comprises the following components in parts by weight: 30-70 parts of cement, 20-70 parts of aggregate, 0.6-5 parts of pigment, 6-40 parts of mixed glue solution of polymer emulsion or redispersible polymer glue powder and water, and 5-40 parts of water. The paint has the remarkable advantages of durability and extremely excellent weather resistance. After 2160 hours of an all-weather aging test, the performance of the mortar is still the same with that of cement mortar and even improved while the performance of an existing product only reaches 1000 hours. The super-high durability of the cement and the flexibility of the polymer are realized. The comprehensive performance is excellent. Saltpetering is obviously inhibited or avoided, and the decorative effect is exquisite. The acid and alkali resistance and anti-freeze-thaw performance are high, the cost is low, and particularly, compared with a building with the service life of more than or equal to 50 years, the maintenance cost of the whole life cycle of the building is reduced by several times, and the paint is suitable for outer walls, inner walls and roofs of the building.

Description

technical field [0001] The invention relates to the technical field of the preparation of water-in-water colorful paints, in particular to the realization of chemical interaction through the combination of cement and polymers to generate ionic bonds, and fibers interspersed with each other. A cement-based water-in-water colorful paint with dual characteristics of polymer reaction curing and emulsion volatilization curing. Background technique [0002] The existing water-in-water colorful paint is made by dispersing water-based color particles in a system composed of water-based film-forming substances, pigments, fillers, water, auxiliary agents, etc., wherein the filler itself does not generate strength due to hydration reaction, and it is closely related to the film-forming material. There are few chemical reactions between substances that enhance the bond strength. During construction, after spraying into a colorful coating, with the volatilization of water, the emulsion ...
