Description
Technical field
The invention belongs to air sterillization sterilization technology fields, specifically disclose a kind of for eliminating the spray of pollutants in air
Mist agent.
Background technique
In recent years, with the development of economy and society, city makes rapid progress, people's living standard is gradually increased, but empty
Gas pollution is increasingly severe, and there is a large amount of pollutants in air.Air pollutants are by gaseous material, volatility object
Air pollution owner caused by the mixture of matter, half volatile substance and particulate matter (PM), in people's daily life environment
If caused by use, construction and decoration (spray painting, finishing material, construction material etc.) as vehicle exhaust, fossil fuel etc., mainly
Include the volatile organic matters such as oxygenatedchemicals, nitrogenous compound (total volatile organism TVOC), sulfur dioxide, PM2.5,
Formaldehyde, benzene etc..Other than welding, air pollution also results in many diseases, at present people by air pollution effect and
The disease incidence of the diseases such as caused visual impairment, respiratory disease, cranial nerve be impaired, pneumonia and cancer is also in the trend of rising.
Currently, having many air fresheners or the air purifying preparation for eliminating formaldehyde on the market, but prevalent effects are not
It is that very well, effect is not also lasting.
Summary of the invention
The purpose of the present invention provide it is a kind of for eliminating the spray of pollutants in air, it is net to solve existing air
Agent is bad to the clean-up effect of pollutants in air, the problem that action time is not grown.
In order to achieve the above object, base case of the invention are as follows: it is a kind of for eliminating the spray of pollutants in air,
Ingredient including following parts by weight: 20-30 parts of ethyl alcohol, 2-5 parts of photochemical catalyst, 5-10 parts of plant extracts, 5-10 parts of gelatin,
2-5 parts of aromatic, 0.5-1 parts of surfactant and 50-70 parts of deionized water.
The working principle and beneficial effect of this base case are:
Photochemical catalyst and plant extracts are applied in combination this programme, and with gelatin by photochemical catalyst and plant extracts packet
It covers, after spray sprinkling, due to the auxiliary of particle water, photochemical catalyst energy moment is attached to body surface, forms photocatalyst
Film, it is not easily to fall off；Photochemical catalyst and plant extracts can be firmly bonded in film simultaneously, slowly be released under the control of gelatin
It puts, to extend its action time, can constantly eliminate the poisonous and harmful substance that the finishing materials such as plate discharge in room air,
There is good eradicating efficacy for volatile organic matters such as formaldehyde, benzene, sulfur dioxide (TVOC) etc..
Photochemical catalyst and plant extracts have the synergistic effect mutually promoted in this spray, can effectively eliminate in air
Pollutant, play purification air, disinfection and sterilization and other effects.
Further, the plant extracts includes take drugs 1-2 parts of grass, 1-2 parts of aloe, 1-2 parts of pomegranate leaf, 1-2 parts of bracketplant
With 1-2 parts of schefflera.
The effective component extracting from above-mentioned several plant can effectively purify air by the synergistic effect between them,
Disinfection and sterilization.Wherein, grass of taking drugs can convert oxygen and carbon dioxide for the nicotine for generation of smoking in air, moreover it is possible to absorb cigarette
Taste peculiar smell, disinfection and sterilization；Aloe can absorb the nocuousness such as formaldehyde, carbon dioxide, sulfur dioxide, the nicotine in air well
Substance, especially PARA FORMALDEHYDE PRILLS(91,95) have good absorption effect, and can also kill the aerial microorganism of floating, adsorb dust；
Pomegranate leaf can purify the sulfur dioxide in air, reduce the lead content in air；Bracketplant and schefflera can will be in air
The harmful substances such as carbon monoxide, hyponitric acid, nicotine, formaldehyde absorb and decompose the innocuous substances such as saccharogenesis and amino acid, and
Duplicator can be decomposed, the benzene that printer is discharged, in addition, the volatile component in bracketplant has significant sterilizing function.
Further, the photochemical catalyst is nano-titanium dioxide.Nano-titanium dioxide itself has nontoxic feature, at present
It is widely used in the industries such as cosmetics, suncream, food, it is extremely intimate with human contact, therefore, using nano-titanium dioxide
As photochemical catalyst, nano-titanium dioxide will not be floated in the sky, cause dust pollution, will not influence human health.
Further, the aromatic be peppermint extracting solution, Jasmine extracting solution, lavender extracting solution, tea extract and
The combination of one or more of Rosa Damascana.The addition of aromatic, can cover the smell of nano-titanium dioxide, and people can also
Different fragrance is selected according to the hobby of oneself.
It is walked the present invention also provides a kind of for eliminating the preparation method of the spray of pollutants in air, including as follows
It is rapid:
(1) preparation of plant extracts: taking the fresh sample of plant, is ground into juice after clean wash with distilled water, will
After juice is dry, it is extracting solution with ethyl alcohol, obtains distillate by distillation, after distillate is concentrated, freeze-drying obtains plant
Extract；
(2) by step (1) plant extracts and nano-titanium dioxide be added in 20% gelatin solution, be dispersed with stirring
5 DEG C are cooled to after uniformly immediately, gelatine microsphere is made hereinafter, being centrifuged；
(3) gelatine microsphere, aromatic, surfactant and the ethyl alcohol in step (2) are added in deionized water, stirring point
It dissipates uniformly up to spray.
Plant extracts and nano-titanium dioxide are wrapped up with gelatin, gelatine microsphere is made, is then added in water and makes
At spray, the rate of release of plant extracts and nano-titanium dioxide can be preferably controlled, when extending the effect of effective component
Between, to improve the function of the purification air and disinfection of this spray.
Further, the plant extracts of the step (1) will be through pulverization process at nanometer grade powder, partial size 300-
400nm., can be preferably by gelatin coatings after plant extracts is ground into nanometer grade powder, dispersion effect is more preferable, while its grain
The specific surface area of son increases, and the function and effect for purifying air are stronger.
Further, in the step (1) when distillation, 2% aqueous citric acid solution is added, the pH value for adjusting distillate is 3.5-
4.5。
In distillation, the pH value of distillate is controlled within the scope of 3.5-4.5, the effective component of plant can be made better
It is dissolved in ethanol solution, improves the content of effective component in the plant extracts finally obtained.
Further, being dispersed with stirring in the step (2) and (3) is all made of water bath sonicator dispersion, bath temperature 50-60
℃.Water bath sonicator dispersion can accelerate rate of dispersion, stir more uniform；By bath temperature control within the scope of 50-60 DEG C, it can make
Gelatin is obtained preferably to dissolve.
