The invention belongs to the technical field of paints, and particularly relates to a multifunctional negative-
ion dry powder paint. The multifunctional negative-
ion dry powder paint is prepared from,by
mass, 8-15% of calcined shell
powder, 25-30% of ash
calcium powder, 10-15% of diatomite, 20-30% of ground
calcium carbonate, 2-5% of
titanium powder, 1-1.5% of talcum powder, 1-2% of kaolin, 0.8-3% of nanometer titania, 1-3% of negative
ion powder, 6-8% of
far infrared powder, 0.7-1% of white
carbon black, 0.4-0.8% of a
cellulose-based surfactant, 0.7-1.5% of redispersible latex powder and 0.03-0.07% of
starch ether, wherein the sum of all the components is 100%. The multifunctional negative-ion
dry powder paint has the advantages that the paint is capable of efficiently absorbing
formaldehyde and other harmful gases and naturally and durably releasing negative ions, excellent in
ultraviolet resistance, mould resistance and sterilizing capacity, good in breathability, capable of adjusting the
humidity of
indoor air and the like, and a
coating has high strength and
toughness, high rigidity, and a highly bright surface and is fine, smooth, and resistant to washing; the negative-ion dry powder paint integrates multiple functions, is safe, harmless and
environmentally friendly, construction is facilitated,
polishing links are not needed, and the health of builders is facilitated.
