Abstract
Nano photo-catalytic composite material provided by the invention, belongs to air purification field.Nano photo-catalytic composite material provided by the present application, in terms of mass parts, including 10~18 parts of formaldehyde catching agent, 5~10 parts of nano photo-catalytic, 5~8 parts of nano-silver ionic, 5~7 parts of negative oxygen ion powder, 15~20 parts of eliminating smell agent, 40.3~52.1 parts of water.The present invention is under the economic benefits and social benefits compound action of formaldehyde catching agent and nano photo-catalytic, formaldehyde, benzene,toluene,xylene organic pollutant can be effectively removed, pass through chemical reaction, can effectively above-mentioned organic pollutant be captured and be decomposed, the space structure for effectively changing organic molecule is converted into tasteless harmless molecule；In addition, enabling nano photo-catalytic composite material effectively to kill bacterium and microorganism under the collective effect of silver ion and nano photo-catalytic；Under the action of eliminating smell agent, peculiar smell can be effectively removed.
Description
Technical field
The present invention relates to air purification field more particularly to a kind of nano photo-catalytic composite material and preparation method and answer
With.
Background technique
Air is one of important external environment for the survival of mankind, in the dirt of the pernicious gases such as formaldehyde, benzene, toluene, hexichol
Existence can cause eye, nose, larynx and respiratory tract in the environment of dye, can also cause headache, dizzy, nauseous, uncomfortable in chest, lassitude
Equal malaise symptoms.The World Health Organization (WHO) is possible studies have shown that the pernicious gases such as Long Term Contact formaldehyde, benzene, toluene, hexichol
It will lead to the malignant diseases such as cancer, leukaemia.
As a large amount of newly constructed houses come into operation, the demand of indoor decorating and building materials furniture is increasingly increased, and the modern times build
The a large amount of uses for building decorations and composite furniture bring a large amount of organic volatile substances into interior, wherein just include formaldehyde, benzene,
The pernicious gases such as toluene, hexichol.In addition, personal belongings, the resting period such as indoor various household items, bedding, shoes, socks are long all
The pollution that a large amount of bacteriums, fungi and dust mite can be assembled is easy to produce in the environment of constant humid, unsmooth, the nutritious substance of ventilation
Microbial contamination, to generate peculiar smell.Microbial contamination is the main of the various infection of initiation, anaphylactia and communicable disease
Reason, these pollutants seriously affect indoor air quality and the health of people.
The method of processing peculiar smell and indoor pollution has much at present, mainly uses the air freshener based on essence,
" cover " peculiar smell on surface makes people feel to be eased to peculiar smell, and actually there is no thoroughly eliminate peculiar smell and pollution；Or
Person is the suction-operated using active carbon and plant, but the method effect is limited, and there is no fundamentally solve pollution problem.
Summary of the invention
In view of this, nano photo-catalytic provided by the invention is multiple the present invention provides a kind of nano photo-catalytic composite material
Condensation material can effectively remove formaldehyde, benzene,toluene,xylene and VOC organic pollutant, and can effectively kill bacterium and micro-
Biology.
The present invention provides a kind of nano photo-catalytic composite materials, in terms of mass parts, including following components:
Preferably, the formaldehyde catching agent includes imidazolidinone and/or adipic dihydrazide.
Preferably, the nano photo-catalytic is nano-titanium dioxide.
Preferably, the eliminating smell agent is 338 ordor removing lotions.
Preferably, the nano photo-catalytic composite material further includes essence, and the mass fraction of the essence is 0.4~0.6
Part.
The present invention provides the preparation methods of nano photo-catalytic composite material described in above-mentioned technical proposal, including following step
It is rapid:
Formaldehyde catching agent, nano photo-catalytic, nano-silver ionic, negative oxygen ion powder and water are heated and mixed；Then again with remove
Taste agent mixing, obtains nano photo-catalytic composite material.
When the nano photo-catalytic composite material includes essence, the preparation method packet of the nano photo-catalytic composite material
Include following steps:
By formaldehyde catching agent, nano photo-catalytic, nano-silver ionic, negative oxygen ion powder, water heating mixing；Then again with taste removal
Agent and essence mixing, obtain nano photo-catalytic composite material.
The present invention also provides described in nano photo-catalytic composite material described in above-mentioned technical proposal or above-mentioned technical proposal
Application of the nano photo-catalytic composite material that method is prepared as air purifying preparation.
Nano photo-catalytic composite material provided by the invention, in terms of mass parts, including formaldehyde catching agent 10~18 part, nanometer
5~10 parts of photocatalyst, 5~8 parts of nano-silver ionic, 5~7 parts of negative oxygen ion powder, 15~20 parts of eliminating smell agent, water 40.3~52.1
Part.Nano photo-catalytic composite material provided by the present application, under the economic benefits and social benefits compound action of formaldehyde catching agent and nano photo-catalytic, energy
Formaldehyde, benzene,toluene,xylene organic pollutant are enough effectively removed, it, can be effectively to above-mentioned organic pollutant by chemical reaction
It is captured and is decomposed, effectively change the space structure of organic molecule, be converted into tasteless harmless molecule；In addition,
Under the collective effect of silver ion and nano photo-catalytic, nano photo-catalytic composite material is enable effectively to kill bacterium and microorganism；
Under the action of eliminating smell agent, peculiar smell can be effectively removed.
Specific embodiment
The present invention provides a kind of nano photo-catalytic composite materials, in terms of mass parts, including following components:
Nano photo-catalytic composite material provided by the invention includes formaldehyde catching agent, and the formaldehyde catching agent is 10~18 matter
Amount part, preferably 12~16 parts.In the present invention, the formaldehyde catching agent preferably includes two acyl of imidazolidinone and/or adipic acid
Hydrazine, when the formaldehyde catching agent is preferably the mixture of imidazolidinone and adipic dihydrazide, the imidazolidinone and oneself two
The mass ratio of acid dihydrazide is preferably 1:1.In the present invention, the formaldehyde catching agent can be effectively removed the first in air
Aldehyde.
In the present invention, when the formaldehyde catching agent preferably includes imidazolidinone, the imidazolidinone is in normal temperature condition
