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.
