Abstract

The invention discloses a water-based diatom ooze functional coating material and a preparation method thereof, and relates to the technical field of decorative coatings. The device is composed of thefollowing raw materials in parts by weight: 15-20 parts of diatomaceous earth, 20-25 parts of organic modified inorganic cementing material, 3-5 parts of nano titanium dioxide, 10-20 parts of titanium dioxide, 10-15 parts of kaolin, 5-10 parts of triple superphosphate, 0-5 parts of talc powder, 0-5 parts of silica fume, 0.2-0.3 parts of a wetting agent, 0.4-0.6 part of a dispersing agent, 0.5-1 part of a thickening agent, 1-2 parts of propylene glycol, 0.1-0.3 part of a defoaming agent, 0.1-0.2 part of bactericide, 0.03-0.05 part of cellulose, 0.1-0.2 part of a levelling agent and 20-30 partsof purified water. The preparation method comprises the following steps: adding additives in the raw materials into purified water, and dispersing and stirring uniformly; adding the diatomaceous earth, the nano titanium dioxide and the filler in the raw materials, and uniformly stirring; adding the organic modified inorganic cementing material, and fully stirring to obtain the water-based diatomooze functional coating material. According to the method, the hardness and the stability of the paint film of the water-based diatom ooze are guaranteed, meanwhile, the water-based diatom ooze is endowed with good air permeability, and the adsorbability of the water-based diatom ooze is guaranteed.

Description

technical field [0001] The invention relates to the technical field of decorative coatings, in particular to a water-based diatom mud functional coating material and a preparation method thereof. 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 wit...
