Abstract
The invention discloses using photocatalyst of titanium dioxide as material for air purification of base material and preparation method thereof, by percentage to the quality, its raw material composition is：Nano titanium oxide 30-40%, nano silicone diatomaceous earth 20-35%, Catergen -5%, tourmaline 15-20%, yellow quartz 5-10%, binding agent 1-5%, dispersant 0.5-1.5%.During preparation, each component is proportionally well mixed；Well mixed material is put into hybrid reaction in the heating kettle of agitating device；Sizing is granulated in injection moulding mould；Sieving；Obtained particle is dried.The scavenging material of the present invention, without specific light source, purification air will be played in the case where there is light source irradiation by adding nano material；Meanwhile specific surface area is big and uniformly, to the harmful substance in air can effective adsorption-decomposition function, there is sterilization, deodorization, presses down taste, can be widely used in the enclosed environments such as interior, in-car.
Description
Technical field
It is especially ripe to be related to a kind of air using photocatalyst of titanium dioxide as base material the present invention relates to a kind of material for air purification
Scavenging material and preparation method thereof, belong to material science and environmental science.
Background technology
As the developing of society, economic progress, people increasingly pay close attention to for environmental pollution, particularly air pollution.
But for most people, no matter work, studying or living, their most of the time is all indoors or the envelope such as in-car
Spent in closed loop border.Although harm of the environmental pollution to health is early, oneself is recognized by people, into twentieth century
The notice of people is just gradually transferred to Shi Nei Kong Qi polluted dyes in the harm of health since phase.The kind of room air pollution
Class is more, pollution sources are extensive, and influence factor is complicated, is endangered to caused by health often more serious than outdoor.Interior Space makings
Oneself warp of quantity research turns into a new focus in material science and environmental science.
Processing method currently used for air pollution mainly has adsorption technology, photocatalysis technology, lower temperature plasma technology
And catalytic oxidation technologies.
Adsorption technology is air purifying process most widely used at present.Adsorption technology is mainly using activated carbon and molecular sieve etc.
High-ratio surface material comes the VOC compositions such as formaldehyde adsorption, benzene and toluene, but existing sorbing material limited sorption capacity, continuation
It is short, it is impossible to secondary use, secondary pollution to be also easy to produce to environment.
Photocatalysis technology mainly by the use of nano titanium oxide as photochemical catalyst, by active hydroxyl free radical and super oxygen from
By the effect of base, can decomposing formaldehyde at ambient temperature, under ultraviolet light, titanium dioxide can be various by indoor species
Harmful substance catalysis oxidation, but it is present catalyst inactivation and needs the same topic of specific light source, and reaction rate needs to be carried
It is high.
Lower temperature plasma technology be by low temperature plasma caused by atmospherical discharges at ambient pressure include electronics, from
Son, oxygen activity species and excited state molecule etc. have high chemically active species, the chemical reaction of many overactivities is able to
Occur, so as to reach the purpose of organic pollution in processing room air.But the technology is easy in process air discharge
Produce the secondary pollution such as nitrogen oxides and ozone.

Inventive principle of the present invention：Cooperative achievement purification of air between raw material of the present invention.Wherein, nano titanium oxide is as light
Catalyst, by the effect of active hydroxyl free radical and superoxide radical, the can decomposing formaldehyde in the case where there is light conditions；Nanometer
Level diatomite main component is silicic acid matter, and there are a countless pores on surface, adsorbable, expansion, decomposes pollutant in air, and have
Damping, deodorization functions；Vitamin C is a kind of hydroxy compounds of small-molecular-weight, and free radical is also easy to produce under light source irradiation, should be certainly
Possess reducing power by base, the hydroxyl free radical in nano titanium oxide can be promoted to carry out decomposing, purifying formaldehyde and hydrogen sulfide etc.
Pernicious gas；Yellow quartz is a kind of natural plant essence, takes from natural tea, is had no toxic side effect.Contain volume phenol in yellow quartz
Property hydroxy (OH) compound (polyphenol compound), can utilize hydroxy in H have reduction decomposition effect, Yi Jiyu
H exchanges the NH in foul smell composition3, the additional complexing such as SH.When formaldehyde in air, benzene, bacterium etc. are caught by yellow quartz, yellow quartz
Contained natural plant essence they can be catalytically decomposed within the extremely short time, prevent secondary pollution.Wherein in yellow quartz
Polyphenol compound can promote the reduction of hydroxyl free radical in nano titanium oxide, itself also possess also proper energy in addition
Power, so pernicious gas in air can more efficiently be decomposed, such as：Formaldehyde and hydrogen sulfide etc.；Polyphenol compound utilizes certainly simultaneously
Oneself reduction can promote the silicate mineral of tourmaline emitting far-infrared, produce anion, adjust function of human body.
Relative to prior art, the invention has the advantages that and beneficial effect：
