Abstract
The present invention relates to one kind of nanometer photocatalyst air sterilizing detergent, and features that the air sterilizing detergent is prepared with nanometer titania in 0.1-5 weight portions, nanometer silica in 2-10 weight portions, sodium hexametaphosphate in 0.3-1 weight portions, surfactant in 0.5-5 weight portions, RE activator in 0.3-1.2 weight portions and deionized water in 70-100 weight portions, and through mixing and emulsifying treatment. The air sterilizing detergent may be sprayed inside house, so that it volatizes naturally and the titania reaches the effects of sterilizing and decomposing harmful gas under the irradiation of ultraviolet ray.
Description
Technical field
The present invention relates to a kind of nanometer photo-catalytic sterilizing and air-cleaning agent, this air freshener can be sprayed in the room, and room air is cleaned, sterilizes, sterilizes.
Background technology
Chinese patent 03134111.X discloses a kind of photo-catalytic coating, is made by following raw materials by weight: titanium dioxide 0.2-1%, emulsion paint 24-44%, deoxygenated water 5575%.Manufacture method: above-mentioned raw materials is put into the nano-pulverization jar, and the work of energized nanometer blender through 1 hour, just can make photo-catalytic coating.The present invention is liquid, can be sprayed on the top layer of objects such as woodwork, wall, plastics, textile, leather, its coating thin and evenly, strong adhesion, transparency be good, do not have that wrinkle does not come off, rub resistance, pollution-free.Have sterilization, eliminate the unusual smell, sterilize, remove the effect of chemical substance and harmful gas.Can be widely used in hospital, school, public place etc.But said composition can not be used for the purification of air in the room.Therefore, need to propose a kind of nanometer photo-catalytic sterilizing and air-cleaning agent.
Summary of the invention
The object of the present invention is to provide a kind of nanometer photo-catalytic sterilizing and air-cleaning agent, this air freshener can be sprayed in the room, the perhaps furniture surface in the room volatilization of giving free rein to, only need faint ultraviolet radiation just can excitation nano titanium dioxide generation cleaning, the effect of sterilization, resolving harmful gas.
The objective of the invention is to be realized by following technical proposals: a kind of nanometer photo-catalytic sterilizing and air-cleaning agent is characterized in that: described air freshener is formed by following feedstock production, and the weight ratio of described raw material is:
Nano titanium oxide 0.1-5
Nanometer titanium dioxide 2-10
Sodium hexameta phosphate 0.3-1
Surfactant 0.5-5
Rare-earth activated dose of 0.3-1.2
Deionized water 70-100
Above-mentioned raw materials is mixed in proportion, promptly can be made into the nano photo-catalytic air freshener through the emulsifying dispersion treatment.
Compared with the prior art the present invention has the following advantages:
1, the present invention has been owing to adopted the nanometer titanium dioxide titanium material, therefore, only needs faint ultraviolet radiation just can excitation nano titanium dioxide to produce to sterilize, the effect of resolving harmful gas.
2, the present invention is to the environment non-secondary pollution, and is nontoxic to human body, have no side effect.
3, sterilizing rate of the present invention reaches more than 95%, and the harmful gas removing rate reaches more than 85%
The specific embodiment
Embodiment one: a kind of nanometer photo-catalytic sterilizing and air-cleaning agent, form by following feedstock production, and the unit of weight of described raw material is a kilogram, its weight proportion is:
Nano titanium oxide 0.1

Surfactant 0.5
Rare-earth activated dose 0.1
Deionized water 70
Above-mentioned raw materials is mixed in proportion, carried out the emulsifying dispersion treatment 20-30 minute, promptly can be made into the nano photo-catalytic air freshener in 5-10 minute by the ultrasonic dispersing machine dispersion treatment then by high-shear emulsion machine.
In the present embodiment, described nano titanium oxide (TiO
2) be mixed crystal type nanometer titanium dioxide, it is made up of the Detitanium-ore-type of 70-80% and the rutile-type of 20-30%.Its particle is spherical, and particle diameter is the 30-80 nanometer.Nanoparticle is subjected to ultraviolet radiation to produce the hole of electronegative electronics and positively charged in water and air, form hole-electron pair, separate with electronics in the hole under electric field action, diverse location to nanoparticle surface moves respectively, at this moment, the oxygen absorption electronics that is adsorbed on nanoparticle surface forms active negative oxygen ion, and the water that is adsorbed on nanoparticle surface is subjected to the nanoparticle surface cavitation to form the hydroxyl radical free radical active specy.Active negative oxygen ion and hydroxyl radical free radical have very high reactivity, can win the electronics in other materials forcefully, and then strong oxidation reaction takes place, organic pollution (as formaldehyde, benzene, dimethylbenzene, toluene, volatile organic gas etc.), inorganic pollution (as ammonia, nitrogen oxide, sulfur dioxide, hydrogen sulfide etc.), antibacterial, microorganism and the organic nutrient substance of depending on for existence thereof all can be oxidized to carbon dioxide, water and corresponding acid, thereby reach the purpose of clean air.
In the present embodiment, sodium hexameta phosphate is a kind of dispersant, its effect is the surface that is adsorbed on nanoparticle (titanium dioxide, silicon dioxide), make nanoparticle in dispersive process, more promptly reach ideal primary particle state by the tension force that reduces its interface through moistening and dispersion, and can prevent effectively that this divided particles from combining again, make it keep stable dispersity.Dispersant can also adopt the inorganic dispersant sodium polyphosphate except can adopting sodium hexameta phosphate; Also can adopt organic dispersing agent polypropylene Barbiturates; Perhaps will piece together usefulness in above-mentioned inorganic dispersant and the above-mentioned organic dispersing agent, wherein inorganic dispersant accounts for 25% of dispersant total amount, and organic dispersing agent accounts for 75% of dispersant total amount.
In the present embodiment, surfactant produces absorption in nanoparticle surface, has changed the surface charge distribution of nanoparticle, and nanoparticle is played the space multistory protective effect, can prevent effectively that nanoparticle from forming aggregate.Present embodiment can adopt a kind of in the following anion surfactant, i.e. sodium alkyl sulfonate, sodium alkyl sulfate, aliphatic alcohol polyoxyethylene sodium sulfate; Can also adopt a kind of in the following non-ionic surface active agent, i.e. aliphatic alcohol polyoxyethylene, alkyl phenol polyoxydivinyl ether, alkylolamides.
