The invention relates to a low-carbon
humidity controlling functional
coating which comprises component A, component B and component C in parts by weight, wherein the component A comprises a
thickening agent, a dispersing agent, a defoaming agent, a
solvent, a bactericide, a
wetting agent and water; the component B comprises
powder,
titanium white, kaolin and heavy
calcium carbonate powder; and the component C comprises an
emulsion, a defoaming agent and a
film forming agent. Compared with the traditional inside wall
emulsion coatings, the
coating has the advantages that hydrophilic porous inorganic minerals are added to ensure that a
coating film has excellent
pollution resistance; after an ordinary coating film absorbs 40g of water in per
square meter, the coating film reaches a saturation state, and most part on the surface of the coating film has a
dew formation phenomenon, however, after one
square meter of the
humidity controlling coating film absorbs 60g of water, the surface of the film has no
dew formation phenomenon; when the indoor
humidity is too high, the porous structure of the film can automatically absorb water in the air and stores the water, and when the room is dry, the water in the film can be released so as to automatically regulate the indoor humidity; and due to the porous structure, the film also has the functions of absorbing sound, insulating heat and deodorizing.
