Abstract

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.

Description

technical field

[0001] The invention relates to a coating, especially a humidity-adjusting coating. Background technique

[0002] Present prior art, the humidity of air is too low or too high all can affect the normal life of people. When the indoor humidity is lower than 40%, people's skin is dry, the resistance of the respiratory system is reduced, bacteria and viruses will take advantage of it, the furniture will be deformed and burst, the powdering of coatings and murals will be accelerated, and it is easy to cause static electricity to catch fire; if it is higher than 65 %, the environment is too humid, the reproduction of microorganisms is accelerated, and the items are prone to mildew, rot or rust. Therefore, the quality of the production environment and life can be improved by adjusting the indoor air humidity, especially for humid and arid areas, adjusting humidity is particularly important. Using an air conditioner to adjust the humidity has high energy consumpti...
