Abstract
Long-acting except formaldehyde structure the utility model discloses one kind, the structure includes diatom ooze base layer, chitosan layer, nanometer titanium dioxide layer successively from inside to outside.The utility model structure reacts to remove formaldehyde by diatom mud layer formaldehyde adsorption, and using the chitosan layer being in close contact with diatom mud layer with formaldehyde, while strengthening the long-term discomposing effect of formaldehyde by the photocatalysis of outside nanometer titanium dioxide layer.The transparent wear for being evenly equipped with through hole can be additionally set up on titanium dioxide layer, to be played a protective role to internal structure, makes the structure timeliness persistently, this is simple in construction to be easy to construction.
Description
Technical field
The utility model is related to household building materials field, more particularly to a kind of long-acting except formaldehyde structure.
Background technology
With the rapid growth in house ornamentation market, construction material is also more and more, and the construction material pair of volatile organic compounds
The living environment of the mankind generates the increase of great threat, especially formaldehyde volatile matter.Formaldehyde pollution problem has had a strong impact on
It is up to the deenergized period of the formaldehyde in furniture 5 to 10 years to the health and quality of life of people, and often, diatom ooze is commonly used at present
Carry out formaldehyde adsorption, but diatomite only plays suction-operated, it is just ineffective when its internal void adsorption saturation, thus have very much
Necessity develops the structure for being capable of long-acting function of removing formaldehyde.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art long-acting except formaldehyde structure there is provided one kind, and the structure is led to
Diatom mud layer formaldehyde adsorption is crossed, and reacts to remove formaldehyde with formaldehyde using the chitosan layer being in close contact with diatom mud layer,
The long-term discomposing effect of formaldehyde is strengthened by the photocatalysis of outside nanometer titanium dioxide layer simultaneously.
The structure includes diatom ooze base layer, chitosan layer, nanometer titanium dioxide layer successively from inside to outside.
In above-mentioned technical proposal, transparent wear is additionally provided with outside described nanometer titanium dioxide layer, described is transparent resistance to
Through hole is evenly equipped with mill layer.Transparent wear plays a protective role to internal structure, and opens up through hole and will not stop nano-silica
Change the photocatalysis of titanium layer, make it still can be in the case where daylight or UV illumination are penetrated, will absorption by catalyst of titanium dioxide
Formaldehyde decomposition be carbon dioxide and water.
Described diatom ooze base layer is uniformly coated by diatom ooze coating to be formed, and described chitosan layer is molten by chitosan
Uniformly coating is formed liquid, and using nanometer titania coating, uniformly coating is formed described nanometer titanium dioxide layer.Described is saturating
Bright antifriction layer is made of PVC material.At least 2.0 millimeters of described diatom ooze matrix ligament thickness.
The utility model also provides a kind of long-acting except formaldehyde plate, is all with upper on the one side or upper and lower surface of sheet material
That states is any long-acting except formaldehyde structure.
The beneficial effects of the utility model are：
React to remove in time with formaldehyde by chitosan layer after diatom ooze formaldehyde adsorption in structure of the present utility model
Formaldehyde, and set nanometer titanium dioxide layer to realize that the effect of formaldehyde is gone in photocatalysis on the outside of it, the structure can remove silicon in time
The formaldehyde that adsorbs in algal gel layer, realize it is long-acting except formaldehyde effect, can also be set on the outside of it be provided with the transparent wear of through hole with
Internal structure is protected, structure of the present utility model can remove formaldehyde in time and timeliness is lasting, and construction method is simple.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the embodiment of the utility model one.
In figure, 1- diatom ooze base layers, 2- chitosan layers, 3- nanometer titanium dioxide layers, 4- transparent wears, 5- through holes,
6- plate bodys.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, it is of the present utility model long-acting except formaldehyde structure, include diatom ooze base layer, shell successively from the inside to the outside
Glycan layer and nanometer titanium dioxide layer.
When being constructed using structure of the present utility model to metope, first, clear up metope, make its it is smooth have no floating dust,
Then diatom ooze coating is uniformly painted on surface of wall, again in brushing chitosan solution thereon after it is dried, after drying again
Brushing nanometer titania coating.The structure construction is simple, by inner side diatom mud layer and the double layer design of chitosan layer, will inhale
The effect of attached formaldehyde and combine with the effect that formaldehyde reacts, the formaldehyde adsorbed in diatom ooze can be removed in time, and in outer layer
Under the photocatalysis of nanometer titanium dioxide layer can further decomposing formaldehyde, timeliness is lasting.
As the presently preferred embodiments, at least 2 millimeters of diatom ooze coating thickness, chitosan layer thickness at least 0.5mm, described receives
Rice titanium dioxide layer thickness is not less than 1 micron.When being spent using each thickness of above-mentioned restriction, the structure tends to reach best effective
Really.
As shown in Fig. 2 for it is a kind of containing said structure it is long-acting remove formaldehyde plate, the plate surface from the inside to the outside successively include silicon
Algal gel base layer, chitosan layer, nanometer titanium dioxide layer, the PVC transparent wearing layer for being evenly equipped with through hole, can use above-mentioned sheet material
In preparing furniture, it is given full play to except formaldehyde is acted on.
Above-described embodiment is used for illustrating the utility model, it is clear that described embodiment is only the utility model one
Section Example, rather than whole embodiments, based on the embodiment, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained on the premise of work, belongs to the scope of the utility model protection.
