Abstract
The utility model discloses self-purified non-woven wallpaper comprising a non-woven wallpaper base, wherein a photocatalyst layer is coated on the non-woven wallpaper base and adhered to the non-woven wallpaper base through an adhesive layer; the contact surface of the photocatalyst layer and the adhesive layer is shaped like a waveform. By adopting the self-purified non-woven wallpaper provided by the utility model, the non-woven wallpaper base and the photocatalyst layer are combined and form a whole; the utilization rate of degerming and formaldehyde-removing functions of the photocatalyst layer is greatly improved; the characteristic of good air permeability of the non-woven wallpaper base is preserved; the secondary pollution of the non-woven wallpaper is avoided; the contact surface of the photocatalyst layer and the adhesive layer is shaped like the waveform, so that the binding force of the photocatalyst layer and the adhesive layer is enhanced.
Description
Technical field
The utility model belongs to home decoration wallpaper technical field, is specifically related to a kind of auto purification nonwoven wallpaper.
Background technology
In recent years, the domestic indoor decoration requirements increases progressively, and causes state's interior finish material quality uneven, thus the hidden danger that underproof poisonous finishing material brings gradually by the consumer be familiar with also more and more stronger to the demand of the finishing material feature of environmental protection.The nonwoven wallpaper is exactly a kind of novel environmental protection finishing material for market demand invention.
The nonwoven hanging raw stock is to mix with natural plant fibre the new green environment protection wallpaper that the small part chemical fibre is manufactured paper with pulp and is shaped through wet method, it does not contain any polyvinyl chloride, polyethylene and chlorine element, have good stereoscopic visual effect and soft feel, and good gas permeability.Nonwoven wallpaper in the market can be given the more pictorial style of wallpaper so that sell through stamp mostly, even also have and on the nonwoven wallpaper, be coated with the PVC(polyvinyl chloride) coating, greatly reduce the feature of environmental protection and the gas permeability of nonwoven wallpaper, increased the secondary pollution (if be coated with PVC coating etc.) to the nonwoven wallpaper.
Photocatalyst is a kind of general name of Nano titanium dioxide as the photosemiconductor material with photo-catalysis function of representative of take.Photocatalyst is under the irradiation of specific wavelength (388nm), can produce the photosynthetic a series of energy conversion process of similar plants Determination of Chlorophyll, be light energy conversion that chemical energy is given the oxidability that photocatalyst surface is very strong, the various organic compounds of oxidable decomposition and mineralising part inorganic matter, and have antibiotic effect.Under irradiation, photocatalyst can absorb and be equivalent to the following luminous energy of band-gap energy, makes its surface excitation occur and produce electronics (e-) and hole (h+).These electronics and hole have very strong reduction and oxidability, can and hold the oxygen of depositing with water and react, and produce the hydroxyl free radical (OH) with super cloudy oxonium ion (O
2).The oxidability of these holes and hydroxyl free radical is greater than 120kcal/mol, has very strong oxidability, almost the molecular link of all formation organic molecules can be cut off and decomposes, organic pollution is resolved into to free of contamination water and carbon dioxide and other innocuous substances.Therefore various harmful chemicals and odorant such as toluene, benzene, benzene homologues, sulfide, amide and harmful bacteria, virus can be decomposed or harmless treatment, reach purify air, the effect of anti-soil deodorizing.Existing photocatalyst solution is all to adopt the mode of later stage hand spray to apply, and above-mentioned artificial process has not only increased cost, due to the inhomogeneities applied, has also reduced the utilization rate of photocatalyst.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of auto purification nonwoven wallpaper of integral type is provided, and when reaching effective degerming, removing the formaldehyde purpose, reduces the secondary pollution to the nonwoven wallpaper; Solve simultaneously the poor problem of adhesion between photocatalyst layer and gluing layer.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of auto purification nonwoven wallpaper is provided, comprises nonwoven wallpaper paper substrate; It is characterized in that: be covered with photocatalyst layer (3) on described nonwoven wallpaper paper substrate.
Described photocatalyst layer is bonded on nonwoven wallpaper paper substrate by the gluing layer.The contact-making surface of described photocatalyst layer and gluing layer is waveform.
The auto purification nonwoven wallpaper that the utility model provides has following beneficial effect:
1, nonwoven wallpaper paper substrate is combined with photocatalyst layer and forms one, greatly improved the degerming of photocatalyst layer, the utilization rate of function of removing formaldehyde;
2, retain the characteristics of the good permeability of nonwoven wallpaper paper substrate, avoided the secondary pollution of nonwoven wallpaper;
3, the contact-making surface of photocatalyst layer and gluing layer is waveform, has increased the adhesion of photocatalyst layer and gluing layer.
The accompanying drawing explanation
Fig. 1 is the structural representation of auto purification nonwoven wallpaper.
Wherein, 1, nonwoven wallpaper paper substrate; 2, gluing layer; 3, photocatalyst layer.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, the auto purification nonwoven wallpaper that the utility model provides, comprise nonwoven wallpaper paper substrate 1; On nonwoven wallpaper paper substrate 1, be covered with photocatalyst layer 3.Photocatalyst layer 3 is bonded on nonwoven wallpaper paper substrate 1 by gluing layer 2.Photocatalyst layer 3 is waveform with the contact-making surface of gluing layer 2.
The auto purification nonwoven wallpaper that the utility model provides is combined nonwoven wallpaper paper substrate and is formed one with photocatalyst layer, greatly improved the degerming of photocatalyst layer, the utilization rate of function of removing formaldehyde.
The auto purification nonwoven wallpaper paper substrate that the utility model provides is body paper, there is no printed layer, has retained the characteristics of the good permeability of nonwoven wallpaper paper substrate, has avoided the secondary pollution of nonwoven wallpaper.
The auto purification nonwoven wallpaper that the utility model provides is waveform by the contact-making surface of photocatalyst layer and gluing layer, has increased the adhesion of photocatalyst layer and gluing layer.
The auto purification nonwoven wallpaper outer surface that the utility model provides is waveform, and having well can be ornamental.
Although with above-mentioned preferred embodiment, the utility model has been made to detailed description, not with above-described embodiment, has limited the utility model.Those skilled in the art should recognize in the situation that do not break away from the given technical characterictic of technical solutions of the utility model and scope; the increase that technical characterictic is done, with the replacement of some same contents of this area, all should belong to protection domain of the present utility model.
