Description
Technical field
The present invention relates to a kind of chemical material technical field, more particularly to a kind of photocatalyst agent suitable for visible ray and its
Preparation method.
Background technology
In recent years, after interior decoration, ammonia that the formaldehyde in adhesive, the benzene homologues in paint, wall discharge etc. is changed
Learning pollutant can slowly be discharged for a long time, and indoor occupant health is constituted a serious threat.People stays in room can feel for a period of time
Dizzy, dizzy, breathing discomfort, the health of indoor occupant is directly affected, so, indoor environment is carried out after finishing comprehensive
Close and administer, be a urgent health engineering.In the prior art, indoor environment, solid are improved in order to remove ski dome
The products such as activated carbon, photocatalyst, formaldehyde lyase are current relatively widely used products.It is clear mainly by way of absorption
Except chemical pollutant, the chemical reactions such as oxidation, decomposition occur due to no, so elimination effect is not known.And the master of photocatalyst
It is titanium dioxide to want composition, and nano titanium oxide is stable, nontoxic and effectively can remove in air and water because of its chemical property
Pollutant and as solving the ideal material of the energy and environmental problem.However, larger (the Eg=of the energy gap of titanium dioxide
3.2eV), light-catalyzed reaction only could occur under ultraviolet light of the wavelength less than 387nm, it means that titanium dioxide can only profit
With a small amount of part in sunshine（About 5%）, and the visible ray (about 45%) being in the great majority in sunshine can not utilize.
Doping vario-property is titanium dioxide is had one of important means of visible light catalysis activity, although can realize can for metal ion mixing
See photocatalytic activity, but because metal ion turns into complex centre, make the catalytic activity of ultraviolet light wave band reduce.2001
Asahi etc. has found that nitrogen substitutes a small amount of Lattice Oxygen and the band gap of titanium dioxide can be made to narrow, active in the case where not reducing ultraviolet light
While make titanium dioxide that there is visible light activity so that turn into a big study hotspot for the doping vario-property of titanium dioxide,
Therefore the principle for removing depollution can be catalytically decomposed in visible ray using the titanium dioxide of doping, exploitation and composition is a visible
The photocatalyst formaldehyde agent for removing formaldehyde can be effectively decomposed under light.Current photocatalyst formaldehyde agent is general all only in the irradiation of ultraviolet light
Lower clearance is preferable, and clearance is very poor under the irradiation of visible ray, and people will indoors using ultra violet lamp still very not
It is convenient.
Therefore, it is necessary to develop a kind of photocatalyst formaldehyde agent that can effectively decompose remove formaldehyde under visible light.
The content of the invention
The technical problem to be solved in the present invention is, it is necessary to removal formaldehyde can effectively be decomposed under visible light by developing one kind,
And the chemical pollutant that material discharges after interior decoration, it has no irritating odor, need not in work progress without secondary pollution
Protect, the photocatalyst agent suitable for visible ray of the parts such as metal will not be corroded.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：This is applied to the photocatalyst agent of visible ray,
Characterized in that, its formula includes following components and matched in parts by weight：50 ~ 70 parts of modified nano-titanium dioxide powder, nanometer
5 ~ 10 parts of silver powder, 5 ~ 10 parts of carbon nano-fiber, 10 ~ 20 parts of mineral matter mixed-powder, 15 ~ 35 parts of bleeding agent, water 1000 ~
1300 parts.Using above-mentioned technical proposal, by using modified nano titanium dioxide powder this can be made to be applied to visible ray
Equally can be with the harmful substance after decomposing formaldehyde and other finishings under the irradiation of photocatalyst agent under visible light, while pass through addition
Mineral matter mixed-powder can make this be applied to the enhancing of the adsorptivity of the photocatalyst agent of visible ray, so as to improve formaldehyde and nuisance
The clearance of matter；It has no irritating odor simultaneously, without secondary pollution.
The present invention further improvement is that, modified nano-titanium dioxide powder be doping metals nanometer titanium dioxide titanium valve
End.
The present invention further improvement is that, the constituent of the mineral matter mixed-powder includes recessed soil, sepiolite and electricity
Gas stone, the proportioning of the recessed soil, sepiolite and tourmaline is 1 by weight：1.5~2：1.3~1.9.
The present invention further improvement is that, modified nano-titanium dioxide powder be doping iron, copper, silver, the nano-silica of lanthanum
Change titanium powder.
The present invention further improvement is that, the recessed soil, the proportioning of sepiolite and tourmaline are by weight：1：1.5：
1.5。
The present invention further improvement is that, the particle diameter of Nano Silver powder is 200 ~ 400nm；The length of carbon nano-fiber is
400~600nm。
The technical problem to be solved in the present invention is to provide a kind of photocatalyst that can effectively decompose under visible light and remove formaldehyde
Except the preparation method of formaldehyde agent.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Suitable for the photocatalyst agent of visible ray
Preparation method, comprise the following steps：
（1）Early-stage preparations：Weigh by weight ratio raw material, it is stand-by；
（2）Mixing corase grind：By step（1）The raw material of middle preparation, which are put into ball mill, to be ground, and is well mixed powder, grain
