In conclusion, the invention has the following beneficial effects:
(1) in the face of the current situation of the air purification technology, the invention discloses the reinforced micelle air purifying agent based on the angle of rapidly grasping air pollutants and firmly fixing the air pollutants without generating secondary pollution caused by pollutant re-release, and the pollutants are rapidly fixed in micelles by virtue of the rapid absorption, adsorption and wrapping effects of the micelles so as to achieve the purpose of rapidly purifying air; when the micelle is formed, some functional components with purification effect are introduced into the micelle through the guiding effect on the micelle, so that the fixing action of the micelle on pollutants, particularly formaldehyde and benzene series is enhanced, and some animal and plant colloids are added at the same time and are enriched on the surface of the micelle, so that the purification capability of the micelle is enhanced, and the strength of the micelle is enhanced by the large-molecule colloids;
(2) based on the structural characteristics of the micelle, namely, hydrophobic lipophilic ends are gathered together and are agglomerated into an inner core structure of the micelle, and then the micelle generates a broad-spectrum purification effect on various pollutants through absorption and adsorption according to the principles of similarity intermiscibility and similarity attraction; in addition, substances such as imidazole, cyclodextrin and the like added into the micelle have stronger purification effect on formaldehyde and benzene series; the micelle structure is stable through the reinforcing effect of the colloid substance on the micelle, and the fixed pollutants can not bring secondary pollution through the dual functions of fixing the functional components and reinforcing micelle wrapping;
(3) the dual function ensures that the pollutants are not released any more; the reinforced micelle has a larger structural size (ten nanometers to hundreds of nanometers), and after the water in the purifying liquid is volatilized, the large-size micelle is deposited instead of floating in the air, so that secondary pollution caused by floating in the air is avoided; the pollutants, namely organic molecules, fixed by the micelles are enhanced, and cannot be released into the air again due to strong binding force with the purification functional components in the micelles, and meanwhile, the re-release of the pollutants is further limited by the wrapping effect of the micelles;
(4) the surfactant comprises a component A and a component B, wherein the surfactant in the component A contains aromatic rings, and the surfactant in the component B does not contain aromatic rings; the micelle prepared by the component A and the component B always has an aromatic ring structure, and according to the similarity and intermiscibility principle, the removal efficiency of the benzene series can be improved, and the peculiar smell removal capability can be improved.

Example (b): the air purifying liquid includes surfactant component A, surfactant component B, imidazole, animal and plant colloid matter and diluent, the imidazole is 2-imidazolidinone, the animal and plant colloid matter is one or several of gelatin, bone glue, hide glue, sesame glue, guar gum, sesbania gum, fenugreek gum, cyclodextrin, chitin and lecithin, and the diluent is water or salt solution.
Wherein, the surfactant of the component A can adopt one or more of dodecyl dimethyl benzyl ammonium chloride, styrene phenol polyformaldehyde condensation polymer polyoxyethylene ether, butyl naphthalene sulfonate, sodium dodecyl benzene sulfonate, nonylphenol polyoxyethylene ether formaldehyde condensation compound or alkylphenol polyoxyethylene ether to be mixed in any proportion; the component B surfactant can be one or more of cetylpyridinium chloride, EO/PO copolymer, fatty acid methyl ester ethoxylate, fatty alcohol polyoxyethylene ether, alkyl polyglycoside, sodium dodecyl sulfate, hexadecyl trimethyl ammonium chloride, deoxycholic acid, sodium taurate and tetradecyl trimethyl ammonium chloride mixed in any proportion.
The preparation method comprises the following steps:
step 1: dissolving a surfactant A, B component and imidazole in a diluent to form a uniform solution M, wherein M is a micelle basic part;
step 2: uniformly dissolving animal and plant colloids in hot water to form a uniform solution N, wherein the N is used as a micelle reinforcing component;
and step 3: and cooling the solution N to room temperature, slowly adding the solution N into the solution M, and stirring at a low speed until a stable reinforced micelle air purification solution is formed.
The components and their contents in examples 1 to 9 and comparative examples 1 to 4 are reported in tables 1 and 2 below.
Table 1:
table 2:
comparative example 1: the micelle-free component, i.e., the surfactant not added, includes the A component and the B component.
Comparative example 2: no micelle strengthening component, i.e. no animal or vegetable gum is added.
Comparative example 3: no functional component, that is, no component with purifying function such as imidazole and cyclodextrin is added.
The purification rates of formaldehyde and toluene by the air-purifying liquids prepared in examples 1 to 9 and comparative examples 1 to 3 were measured and recorded in tables 3 and 4.
Table 3 (formaldehyde purification rate):
table 4 (toluene purification rate):
the conclusion can be drawn from the above experiments: examples 1 to 9 the average value of the purification of formaldehyde at normal temperature was 96.6%, the purification rate of toluene was 88.2%, the release rate of toluene after heating to 50 ℃ was 0.2%, and the release rate of toluene was 1.5%; the average values of the purges in comparative examples 1 to 3 and the average values after warming to 50 ℃ are recorded in table 5.
Table 5:
from the above data, it can be concluded that:
1. the air purifying agent without the formed micelle in the comparative example 1 has low purification rate and high-temperature release;
2. the release rate of the micelle-free enhancer in comparative example 2 was lower than that of the micelle-free enhancer in comparative example, and thus it was found that the micelle was a main influence factor for suppressing the release;
3. the purification rate was decreased compared to the example without the functional component in comparative example 3, but the release was relatively low due to the presence of the reinforcing micelle.
