Problems solved by technology

[0012] Although nano-TiO 2 The air purification liquid as an active ingredient has a high-efficiency purification effect, but it has the following technical problems: the production and bonding process of interior decoration boards introduces more adhesives and coatings, and these adhesives and coatings contain considerable Organic solvents such as aldehydes, ketones, and esters. The diffusion of these organic solvents is different due to the location of their existence (including the location of the relative plate and its location in the adhesive or coating), resulting in these organic solvents being gradually Diffusion into the air, so it needs to be purified with air purification liquid many times, and the purification process is more troublesome

Embodiment 1-4

[0034] Embodiment 1-4: a kind of air purification liquid, is prepared by following method:

[0035] (1) Take the P123 type PEO-PPO-PEO triblock copolymer (ie PEO 20 -PPO 70 -PEO 20 ), the glycerol of formula quantity and the water of 2 / 3 formula quantity are mixed, stir to obtain mixture A;

[0036] (2) Take the carboxymethyl cellulose of formula quantity and the methanol of 2 / 3 formula quantity and mix, stir to obtain mixture B;

[0037] (3) Take the nano-titanium dioxide photocatalyst of formula quantity (the anatase phase detected by XRD is 10wt%, all the other are rutile type), the water of 1 / 3 formula quantity, the methanol of 1 / 3 formula quantity mix, stir evenly Obtain mixture C;

[0038] (4) Stir the mixture C, and add the mixture A and the mixture B dropwise to it at the same time, and stir evenly;

[0039] The formula of embodiment 1-4 is as shown in table 1.

[0040]The formula (unit: kg) of table 1 embodiment 1-4

[0041]

Embodiment 5

[0042] Embodiment 5: An air purification liquid, the difference from Embodiment 1 is that the PEO-PPO-PEO triblock copolymer is selected as F127 type.

Embodiment 6

[0043] Embodiment 6: A kind of air purification liquid, the difference with embodiment 1 is that methanol is replaced by ethanol.

Abstract

The invention discloses an air purifying solution and a preparation method thereof. The air purifying solution is prepared from the following components: 3 to 7 weight percent of nano titania photocatalyst, 8 to 10 weight percent of PEO-PPO-PEO triblock copolvmer, 2 to 4 weight percent of carboxymethyl cellulose, 9 to 13 weight percent of glycerol, 40 to 45 weight percent of C1 to C2 alcohols and30 to 34 weight percent of water, wherein the C1 to C2 alcohols are methanol or ethanol. The air purifying solution can be used for continuously purifying after being used for one time and has the advantage of simplifying purification procedures.

Description

technical field [0001] The invention relates to an air purification liquid and a preparation method thereof. Background technique [0002] In recent years, with the use of a large number of chemical building materials, the indoor air quality is worrying, and air pollution has become an invisible killer that endangers human beings. [0003] At present, research on improving indoor air quality has become one of the hot spots. Among them, photocatalyst technology is a relatively recognized direction at present, and nano-TiO is used in photocatalyst 2 as the main research direction. TiO 2 It is an n-type semiconductor with a forbidden band width of 3.2e V. When titanium dioxide is irradiated with light whose light energy is greater than or equal to its forbidden band width (or when incident light with a wavelength less than or equal to 387nm is irradiated on the surface of titanium dioxide), the valence band The electrons can be excited to jump to the corresponding conductio...
