Problems solved by technology

However, organic pollutants in interior decoration materials and furniture will be continuously released, and 8 hours of sleep is enough to accumulate above the maximum limit of the national standard (0.10 mg / m3). In addition, the gas containing free formaldehyde is greater than the air quality (in The indoor air has a higher concentration below 150 cm), the height of the bed is basically below 60 cm, and the part containing free formaldehyde is basically on the respiratory belt of the sleeper. Therefore, the ordinary photocatalytic method to control indoor pollution is not available The purification effect is not obvious under the condition of strong light

Abstract

The invention discloses a photocatalyst deodorant and a preparation method thereof. The photocatalyst deodorant comprises, by weight, 5-10 parts of nanometer titanium dioxide, 1-3 parts of anion powder, 1-2 parts of phosphoric acid, 1-5 parts of penetrating agents, 1-5 parts of dispersing agents, 5-10 parts of sodium bicarbonate, 70-90 parts of deionized water, 3-5 parts of aloe gel and 10-15 parts of tea polyphenol. The invention further discloses the preparation method of the photocatalyst deodorant, and through adsorption and degradation of a super catalyst indium phosphate in the night orin a dark condition, requirements on light condition can be reduced.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a photocatalyst deodorant and a preparation method thereof. Background technique [0002] At present, there are many ways to treat indoor air, such as spraying photocatalysts, deodorants, and formaldehyde-dissolving enzymes. The traditional nano-titanium dioxide photocatalyst has certain disadvantages: only in the range of 254nm or 365nm of ultraviolet light can there be an ideal purification effect. And general part room is difficult to daylighting in the family, and there is no sunlight at night. However, organic pollutants in interior decoration materials and furniture will be continuously released, and 8 hours of sleep is enough to accumulate above the maximum limit of the national standard (0.10 mg / m3). In addition, the gas containing free formaldehyde is greater than the air quality (in The indoor air has a higher concentration below 150 cm), the height of the bed is basic...
