Abstract
It is a kind of efficiently to remove formaldehyde air cleaning spray, belong to technical field of air purification.It is characterized in that described efficiently except purifying formaldehyde spray is compounded by a variety of safe components, formaldehyde scavenger 0.1-5.0 wt.%, stabilizer 0.05-3.0 wt.%, dispersing agent 0.1-2.5wt.%, buffer 0.2-2.0 wt%, fungicide 0.05-1.0 wt.%, remaining is deionized water.This, which efficiently removes purifying formaldehyde spray and is combined into safe and harmless product by formaldehyde scavenger and formaldehyde molecule, effectively removes formaldehyde in air pollution, while fungicide efficiently kills the microorganisms such as bacterium, fungi in air, improves air quality, ensures human health.
Description
Technical field
Formaldehyde air cleaning spray is efficiently removed the present invention relates to a kind of, belongs to technical field of air purification.
Background technique
Formaldehyde is one of representative pollutant of room air, is a kind of Systematic toxin.Nineteen ninety-five formaldehyde is just international
Agency for Research on Cancer be determined as can carcinogenic substance, be in second on China's toxic chemical priority acccess control list.Formaldehyde is to people
The influence of body health is mainly manifested in allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction
Etc..Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, serious to induce nasopharyngeal carcinoma, colon cancer, brain tumor
And the gene mutation of nucleus, lead to the single-stranded interior commissure of DNA and DNA and protein commissure and inhibits the reparation of DNA damage.State
1 hourly average value of family's standard GB/T 18883-2002 " Indoor Air Quality standards " regulation concentration of formaldehyde must not exceed 0.1 mg/
m3, GB 50325-2010 " code for indoor environmental pollution control of civil building engineering " requires I class civil building engineering indoor environment
Middle concentration of formaldehyde must not be higher than 0.08 mg/m3。
At present except the method that formaldehyde spray mainly uses photocatalysis Formaldehyde decomposition and chemical absorbing.Photochemical catalyst is (at this stage
Mainly nano-titanium dioxide) by absorbing energy production light induced electron and photohole in ultraviolet light, so that first will be aoxidized
Aldehyde.Usual photochemical catalyst can only absorb ultraviolet light, and very low to the absorptivity of visible light in sunlight, and which results in current
The photochemical catalyst used is catalyzed the inefficient of its decomposing formaldehyde, and during light-catalyzed reaction formaldehyde incomplete oxidation meeting
Other substances are generated, secondary pollution is be easy to cause.Therefore in contrast, purifying formaldehyde spray is just shown using chemical absorption method
Apparent advantage.Chemical absorbing refers to be captured by selecting suitable compound and formaldehyde that strong interaction occurs, and is changed
It is fast to learn absorption process reaction rate, good absorption effect, and can be according to the different role mechanism of absorbent and formaldehyde to absorbent
Type, component, proportion be adjusted.
CN104383655 A discloses a kind of preparation method and its spray except formaldehyde spray, by dandelion, Radix Isatidis and
Herba Houttuyniae extract is mixed with Radix Glycyrrhizae, folium artemisiae argyi and Pericarpium Citri Reticulatae volatile oil.The acquisition of plant extraction liquid needs to consume mass energy
And plant resources, and the comparison of ingredients of plant extraction liquid is complicated, and the Product safety reacted with formaldehyde is not very clear, this
Outer volatile oil is usually some volatile organic matters with armaticity, and influence of these substances to indoor air quality can not yet
Accurate evaluation；Also it is not added with sterilization component in foregoing invention, the microorganism in air can not be killed, there are obvious applications
Defect.Therefore need to develop a kind of safety non-pollution, it is lower-cost efficiently to remove formaldehyde air spray, while also to have certain
Bactericidal property.
Summary of the invention
The present invention is a kind of efficiently except formaldehyde air cleaning spray, belongs to technical field of air purification.It is characterized in that institute
It states efficiently except purifying formaldehyde spray is compounded by a variety of safe components, formaldehyde scavenger 0.1-2.0 wt.%, stabilizer 0.05-
0.5 wt.%, dispersing agent 0.1-0.5wt.%, buffer 0.2-1.0 wt%, fungicide 0.05-0.2 wt.%, remaining is deionization
Water.The purification spray has the features such as easy to use, purification efficiency is high, and persistence is good, and safety is without secondary pollution, is able to achieve to sky
Effective purification of formaldehyde pollution in gas.
It is proposed by the present invention a kind of efficiently except formaldehyde air cleaning spray, by formaldehyde scavenger, stabilizer, dispersing agent, delay
Electuary, fungicide and water are formulated.Formaldehyde scavenger is sodium hydrogensulfite, asparagine, lysine, glutathione, polyamides
The one or more of imines, polypyrrole, polyaniline, the content of formaldehyde scavenger are 0.1-5.0 wt.%, preferably 1.0-4.0
wt.%；Stabilizer is the one or more of alpha-cyclodextrin, malic acid, citric acid, beta-cyclodextrin, polyethylene glycol, and stabilizer contains
Amount is 0.05-3.0 wt.%, preferably 0.1-2.0 wt.%；Dispersing agent is fatty alcohol polyoxyethylene ether, aliphatic alcohol polyethenoxy
Sodium sulfonate, lauryl methacrylate, Tween-20, Tween-80, Arlacel-20 it is one or more, the content of dispersing agent is
0.1-2.5 wt.%, preferably 0.5-2.0 wt.%；Buffer is sodium carbonate, sodium bicarbonate, sodium dihydrogen phosphate, dibastic sodium phosphate
One or more, buffer content is 0.2-2.0 wt%, preferably 0.5-1.5 wt.%；Fungicide be benzoisothiazolinone,
Sodium dichloro cyanurate, dodecyl dimethyl benzyl ammonium bromide, organosilicon quaternary ammonium salt, polyquaternium, alkyl-glucoside
One or more, sterilization agent content is 0.05-1.0 wt.%, preferably 0.1-0.7 wt.%.It is of the present invention a kind of efficient
Except formaldehyde air cleaning spray is using simply, safety is good, and purification efficiency is high, and clean-up effect persistence is good, and sky is being effectively treated
In gas while formaldehyde pollution, moreover it is possible to kill the microorganisms such as bacterium, the fungi in air, ensure that indoor air quality.
