Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows the implementation for meeting the disclosure
Example, and together with specification for explaining the principles of this disclosure.It should be evident that the accompanying drawings in the following description is only the disclosure
Some embodiments for those of ordinary skill in the art without creative efforts, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 shows the preparation method flow chart of material for air purification in disclosure exemplary embodiment.
Specific embodiment
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes
Formula is implemented, and is not understood as limited to example set forth herein；On the contrary, thesing embodiments are provided so that the present invention will more
Fully and completely, and by the design of example embodiment comprehensively it is communicated to those skilled in the art.Described feature or
Characteristic can be incorporated in any suitable manner in one or more embodiments.
This example embodiment provides firstly a kind of material for air purification, which may include following heavy
Measure the raw material of percentage: polarity electrical stone 30%-45%, carbon nanotube 5%-15%, molybdenum oxide 5%-12%, acrylic resin
20%-30%, titanium dioxide compound 15%-20%.
In one example, polarity electrical stone may include dravite, iron tourmaline, iron dravite, elbaite
At least one of.Polarity electrical stone is a kind of silicate mineral, its chemical component is mainly silicate, boron, magnesium, aluminium etc.,
And polarity electrical mountain flour physical efficiency continues permanent release anion, for example, by polarity electrical mountain flour breakdown mill to 0.1 μm -5 of partial size
μm powder when, the hydroxyl group anion per cubic centimeter that can release more than 1200, and it is radiation-curable go out wavelength at 2 μm -18 μm
Far infrared in range.Anion and far infrared, which can play the role of purification air, especially anion, to be passed through
Physical absorption, chemical breakdown, the electrically comprehensive functions such as neutralization, have to purify aldehyde, ammonia, benzene etc. that finishing material and furniture release
Evil gas.
Carbon atom has good Bonding property, can not only form structurally consummate diamond and graphite, can also form tool
There are high adsorption, the unformed porous carbon of abundant fault of construction.The aperture system of conventional porous carbon is mainly by its knot abundant
Structure defect is formed, different from the aperture system that zeolite molecular sieve etc. has pore structure to construct completely, and aperture system has certain
Randomness, therefore its pore forming process and final pore structure are difficult to control.And the appearance of carbon nanotube makes the shape in carbon structure
It is possibly realized at completely regular pore structure.Especially single-walled carbon nanotube is made of single layer cylindricality graphite linings, and diameter is big
Small distribution is small, and defect is few, uniformity consistency with higher, with more regular 1-dimention nano grade hole.
Carbon nanotube in the present embodiment material for air purification has good suction to pernicious gases such as aldehyde, ammonia, benzene, TVOC
Attached performance.The study found that the key between sorbate and surface is than between sorbate when carbon nanotube adsorbs organic gas
Key it is strong, while to the desorption temperature of organic gas, desorption activation energy will be higher than conventional activated carbon.
Molybdenum oxide in the present embodiment material for air purification is very stable in air, and can be with the minor amount of water knot in environment
Output hydrogen ion is closed, subacidity superficiality is formed, causes bacterium that can not survive to change environment.It is found by many experiments,
Molybdenum oxide and acrylic resin have good suitability, when the dosage of molybdenum oxide is the 4% of acrylic resin, in 6h
Kill 108Escherichia coli and staphylococcus aureus.
Acrylic resin in the present embodiment not only increases the bactericidal property of molybdenum oxide, and occupies material for air purification
The acrylic resin of 20%-30% also adds amalgamation and suitability between material for air purification and coating, in very great Cheng
Influence of the material for air purification to coating performance itself is reduced on degree, when this material for air purification is added in coating, and is made
When painting metope with the coating, wall surface coating does not allow the phenomenon for occurring cracking or adhesiveness is bad.
In one embodiment, titanium dioxide compound can be the compound of cuprous oxide and titanium dioxide.Titanium dioxide
Titanium itself can serve as a kind of material for air purification, and harmful organic substance in environment and the nitrogen oxygen in atmosphere can be catalytically decomposed in it
Compound and sulfide also have the function of purification, antifouling deodorization etc..But since the catalysis of titanium dioxide reaction is light provocative reaction,
When there is no light, catalysis reaction will not occur.In the prior art, overcome usually using titanium dioxide package metal nano powder
This defect, but the optically catalytic TiO 2 adsorption capacity being prepared is weak, immobilized difficulty, it is big using difficulty in coating.And
Test proves that the compound of cuprous oxide and titanium dioxide in the material for air purification that the disclosure provides, not only has
Higher anti-microbial property, while possessing again preferably except ammonia performance.
In one embodiment, the material for air purification that the disclosure provides can also include a small amount of active carbon or hydroxyl phosphorus
Lime stone is to further strengthen the absorption to pernicious gases such as indoor aldehyde, ammonia, benzene, TVOC.
A kind of preparation method of material for air purification is additionally provided in this example embodiment, as shown in Figure 1, this method can
With the following steps are included:
Step S101: polarity electrical stone and carbon nanotube are smashed and ground respectively, are sieved as 0.1 μm -5 μm of partial size of powder
Molybdenum oxide is ground up, sieved the powder for 1 μm -10 μm by body；
Step S102: weighing quantitative cuprous oxide and be added to absolute ethanol, and the butyl titanate ethyl alcohol of preset concentration is added
Solution, be uniformly mixed, sufficiently reaction after centrifugation, alcohol wash, be dried in vacuo cuprous oxide and titanium dioxide compound；
Step S103: polarity electrical mountain flour body, the 5%- of the 30%-45% after weighing sieving by weight percentage respectively
The acrylic resin of 20%-30% is added in 15% carbon nanotube dust, is uniformly mixed, adds the molybdenum oxide of 5%-12%
The compound of the cuprous oxide and titanium dioxide of powder and 15%-20%.
In step s101, polarity electrical stone can first pass through the impurity of washing, pickling removal surface in advance before smashing and grinding.
