The invention relates to an indoor multifunctional waterborne
coating and a preparation method thereof. The indoor multifunctional waterborne
coating comprises the following raw materials in parts by weight: 20-38 parts of an
acrylate purifying emulation, 18-35 parts of
distilled water, 0.05-0.2 part of a
wetting agent, 0.2-1 part of a dispersing agent, 0.5-2 parts of a cosolvent, 15-25 parts of
titanium dioxide, 3-8 parts of talcum
powder, 5-15 parts of
mica powder, 0.1-0.5 part of a mildewcide
biocide, 0.05-0.3 part of a
plant extract, 0.3-0.8 part of an anionic additive, 1-1.5 parts of a film forming additive, 1-2 parts of a waterproof agent, 0.02-0.1 part of a
thickening agent, 0.02-0.1 part of
hydroxyethyl cellulose, 0.1-0.5 part of a
rheology modifier and 0.1-0.5 part of a defoaming agent. The indoor multifunctional waterborne
coating has the advantages of simple process, relatively low cost, high waterproofness, stability, environment friendliness and safety; the added
plant extract is fresh in smell and capable of taking a favorable mosquito expelling effect; the anionic additive can be used for favorably removing harmful substances such as
formaldehyde and
benzene and takes the effect of purifying the environment; and the multifunctional approaches of the indoor multifunctional waterborne coating in indoor decoration are ensured.
