Description
Technical field
The present invention relates to air purifying preparation field more particularly to a kind of antibiosis anti-acarien air based on nano-titanium dioxide
Cleanser and preparation method.
Background technique
Currently, there are two main classes for the most common air purifying preparation on the market.One kind is that addition has high porosity, Gao Bibiao
The absorbent-type air purifying preparation that area material is prepared, wherein adsorbent mainly active charcoal, diatomite or porous graphite
Alkene etc..Such air purifying preparation after spraying, can be within a short period of time to the pollutant quick adsorption in room, to reduce
Pollutant concentration, but persistence is poor.And the volatile organic matter (VOCs) in air still can dissipate again after absorption
It is sent in air, is detrimental to health.Therefore, absorbent-type air purifying preparation fails to be inherently eliminated pollutant.Such sky
Gas cleanser is limited to microorganisms removal abilities such as dust mite, bacterium, viruses in air, and can be because itself has certain face
Color, and influence the coloured light of indoor wall or ornament and be not appropriate for indoor use.Another kind of is that addition has decomposition harmful dirty
The breakdown type air purifying preparation that the substance of dye object is prepared, wherein the substance with decomposing pollutant ability mainly has nanometer two
The photocatalysts such as titanium oxide, nano zine oxide or the ore of powder capable of releasing negative ion etc..The air purifying preparation of addition photocatalyst is killing
Bacterium, degradable organic pollutant etc. all have good effect, but photocatalyst need under the conditions of having light competence exertion go out compared with
Good effect, use condition receive certain limitation, meanwhile, there are also to be hoisted for the bacteriostasis rate of photocatalyst.Add negative ion powder
Substance, although having the effects that preferable antibacterial, depositing dust, negative ion powder is generally natural crystal, wherein containing micro
Radioactive substance can be caused to seriously endanger, is forbidden to use in many national standards to human body.
For air purifying preparation, patent CN108636104A discloses a kind of preparation method of composite air purifying agent,
The method uses diatomite as adsorbent, using substances such as graphene oxides come decomposing organic pollutant.Such air cleaning
Agent can be played the role of centainly purifying air, but efficiency is lower, to harmful substance using absorption and the synergistic effect decomposed
Capacity of decomposition is poor, not enough thoroughly.Patent CN108554065A discloses a kind of preparation method of high efficient air purifier, this side
Method uses modified coal and porous graphene with high absorption capacity, with the nano-titanium dioxide with catalytic decomposition organic matter
And anion miberal powder synergistic effect, dust can be adsorbed simultaneously and can effectively decompose volatile organic matter, but due to negative
Ion miberal powder has larger potential hazard to human body, while this product itself color is heavier, is not appropriate for indoor furniture use, and more
It is purified suitable for outdoor air.Patent CN108499337A discloses one kind and efficiently removes nitrogenous contamination gas figure air cleaning
Agent composition mainly uses natural plant essential oils to carry out fresh air, using the active powdered carbon of load chloride adsorbing and
Decomposing pollutant, the air purifying preparation of the method preparation is using chloride as sterilization, oxidant, and lasts are poor, and human body is not
It can be with Long Term Contact.For antibiosis anti-acarien air purifying preparation, it is empty that patent CN108704607A discloses a kind of Y type molecular sieve
The preparation method of gas cleanser, although the method has prepared nano-titanium dioxide molecular film, purity by low temperature hydrolysis
It is lower, the partial size and quality of nano-titanium dioxide cannot effective control, therefore photocatalysis effect is poor, it is necessary to compared with intense light source
Lower competence exertion effect, greatly limits its application scenarios.Patent CN108479286A disclose a kind of air purifying preparation and its
Preparation method, the method mainly based on natural plant extracts, has the effect of stronger fresh air, but sterilizes and explain
The ability of pollutant is limited.Patent CN106345202A discloses a kind of macromolecule air purifying preparation and preparation method thereof, this side
The air purifying preparation of method preparation has certain antibacterial ability because adding the dissolution types macromolecule organic antibacterial agents such as laurene, but
It is weaker for the capacity of decomposition of pernicious gas, while the long-time service of dissolution type antibacterial agent may be detrimental to health.Patent
A kind of preparation method of antibacterial type air purifying preparation disclosed in CN108452673A is then by lanthanide-doped zirconium oxide, two
The photocatalysts such as titanium oxide play the role of antibacterial, antibacterial, the method still fail to solve photocatalyst catalytic efficiency it is lower and
The application scenarios compared with intense light source are needed to limit, while preparation method is complex.
