Abstract

The invention provides a water-based sepiolite organic-inorganic mineral coating material and a preparation method thereof. The water-based sepiolite organic-inorganic mineral coating material comprises 20-30% of water, 15-20% of sepiolite powder, 5-10% of organic resin, 10-15% of inorganic cementing material, 3-5% of nano titanium dioxide, 25-45% of filler and 1.5-4.5% of additive. The preparation method of the water-based sepiolite organic-inorganic mineral coating material comprises the following steps: adding the components according to a specific sequence, and uniformly stirring. The water-based sepiolite organic-inorganic mineral coating material solves the technical problems that the organic paint influences the environment and influences the efficiency of the functional componentsand the inorganic paint is easy to crack in the prior art.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based sepiolite organic-inorganic mineral coating material and a preparation method thereof. Background technique [0002] At present, the film-forming substances of architectural coatings are mainly organic emulsions, which have a great impact on the environment due to the high content of volatile components. Moreover, the organic resin forms a dense paint film after forming a film, which seriously hinders the adsorption function of the functional coating material and reduces its performance of purifying air. [0003] Inorganic architectural coatings have nanoparticles with a large specific surface area and are easy to form a network structure, which is irreversible. Therefore, the coating film is hard, has strong adhesion, and has excellent water resistance and chemical resistance. However, when the inorganic gelling material is formed into a film, it shrinks greatly, and the ...
