Technical Field

The invention relates to the technical field of preparation of water-in-water multicolor coatings, in particular to an ultrahigh-durability cement-based water-in-water multicolor coating which realizes chemical interaction by generating ionic bonds through combination of cement and polymers, is mutually interpenetrated by paving fibers, and has the characteristics of both ultrahigh durability and flexibility of the cement and the characteristics of reaction curing of the cement and the polymers and volatilization curing of emulsion.

Background

The existing water-in-water multicolor paint is prepared by dispersing water-based colored particles in a system formed by water-based film-forming substances, pigments, fillers, water, additives and the like, wherein the fillers do not generate strength due to hydration reaction and hardly generate chemical reaction for enhancing the bonding strength between the fillers and the film-forming substances. In the construction, after the colorful coating is sprayed, the emulsion forms bonding and wrapping on the pigment and the filler in the process of gradually solidifying to form a film along with the volatilization of water, so that colorful particles are formed, and the colorful particles are connected into a whole through the connecting emulsion to form the colorful coating. In this system, the polymer emulsion of organic material is the only material to form and bond the colored particles together, and the short life cycle of the polymer is determined by the organic material itself. Therefore, the durability, weather resistance and other performances of the existing water-in-water multicolor paint are determined by the performances of the polymer emulsion made of organic materials, so that the durability and weather resistance are poor, the artificial weather aging resistant time is only 500-1000 h, which is about 8-13 years, and the difference is too large compared with the building service life of more than 50 years.
