Abstract

The invention discloses a biological functional inorganic dry powder coating and a preparation method thereof. The biological functional inorganic dry powder coating is characterized by comprising the following components in parts by weight: 30-50 parts of white cement, 0-5 parts of nano titanium dioxide, 10-20 parts of redispersible rubber powder, 1-5 parts of titanium dioxide, 10-20 parts of glass fiber powder, 0.05-0.1 part of cellulose ether, 0.09-0.2 part of a defoaming agent, 0.08-0.1 part of an early strength agent, 0.05-0.1 part of a water reducing agent, 0.5-0.1 part of a retarder, 15-30 parts of packing and 0.3-5 parts of an inorganic pigment. The biological functional inorganic dry powder coating disclosed by the invention meets requirements of related standard provisions, is free of harmful substances such as VOC (volatile organic compounds), benzene and formaldehyde heavy metals, has good environmental-friendliness, and is capable of adsorbing and degrading toxic and harmful gases, purifying air and effectively preventing mold and inhibiting bacteria.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to an ecologically functional inorganic dry powder coating and a preparation method thereof. Background technique [0002] In recent years, my country has faced serious air pollution problems, especially the smog problem, which has greatly affected the normal life, health and safety of residents. Among them, volatile organic pollutants (VOC) are one of the main sources of PM2.5 in the ambient air, and the resulting secondary pollutants are also the cause of haze weather. [0003] VOC emissions from the paint industry are one of the sources of VOCs. For this reason, the central and local governments have successively issued various policies to limit the emissions of VOC volatiles in the construction sector. At present, domestic architectural coatings are mostly organic coatings, which will release harmful and toxic components during production and use, endangering the...
