Abstract

The invention discloses a liquid diatom ooze functional coating material, and relates to the technical field of decorative coating. The liquid diatom ooze functional coating material comprises, by weight, 15-20 parts of diatom ooze, 3-5 parts of nanometer titanium dioxide, 20-25 parts of organically modified organic cementitious materials, 0.2-0.3 part of wetting agents, 0.4-0.6 part of dispersingagents, 0.5-1 part of thickening agents, 1-2 parts of propylene glycol, 0.1-0.3 part of defoaming agents, 0.1-0.2 part of bactericides, 0.03-0.05 part of celluloses, 0.1-0.2 part of leveling agents,10-20 parts of titanium dioxide powder, 10-15 parts of kaolin, 5-10 parts of heavy calcium carbonate, 0-5 parts of wollastonite powder and the balance purified water. Sand filtration, ultra-filtrationand reverse osmosis filtration are carried out on water to obtain the purified water with a TDS (total dissolved solids) value lower than or equal to 50; additives among raw materials are added intothe purified water and are uniformly dispersed and stirred to obtain first mixtures; the diatom ooze, the nanometer titanium dioxide and fillers among the raw materials are added into the first mixtures and are uniformly stirred to obtain second mixtures; the organically modified organic cementitious materials are added into the second mixtures and are sufficiently stirred to obtain the liquid diatom ooze functional coating material. The liquid diatom ooze functional coating material has the advantages that the hardness and the stability of paint films formed by the water-based diatom ooze canbe guaranteed, the water-based diatom ooze is good in gas permeability, and the adsorption of the water-based diatom ooze can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of decorative coatings, in particular to a liquid diatom mud functional coating material. Background technique [0002] As we all know, the film-formers of architectural coatings are mainly organic emulsions, and due to the high content of volatile components, the pressure on the environment is also increasing. Inorganic architectural coatings have nanoparticles with a large specific surface area, which is easy to form a network structure, and this network structure 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 coating film is easy to crack. In order to overcome this shortcoming, researchers have used physical blending or chemical polymerization to combine inorganic gelling materials with organic polymers, and the organic po...
