Abstract
The invention relates to a preparation method of wallpaper capable of degrading formaldehyde and organic volatile matters of indoor air through photocatalysis. The preparation method comprises the following steps: (1) selecting finished wallpaper as a raw material, coating a layer of water-based macromolecule glue on the surface of the wallpaper, wherein the glue is high in transparency so as not to impact the printed figures and colors of the wallpaper after the glue is dried into a film; (2) spraying titanium dioxide nanopowder with a photocatalysis function on the water-based macromolecule glue, or preparing the titanium dioxide nanopowder into a dispersion liquid for spraying; (3) putting the wallpaper in a drying tunnel for drying off; bonding the bottom of the titanium dioxide nanopowder with the wallpaper through the transparent water-based macromolecule glue. The bottom of the titanium dioxide nanopowder is bonded with the wallpaper through the transparent water-based macromolecule glue, and the most of the surface of the titanium dioxide nanopowder is kept in the initial condition, so that the wallpaper is not coated with the glue and very high in photocatalytic activity, and can degrade formaldehyde and organic volatile matters.
Description
Technical field
The invention belongs to indoor decoration wallpaper field, relate to a kind of preparation technology with formaldehyde and organic volatile effect wallpaper in photocatalytic degradation of indoor air.
Background technology
Because the materials such as coating in fitment process, paint, wood-based plate, binding agent discharge a large amount of organic volatiles, make newly-decorated architecture indoor air severe contamination, human body is produced to huge injury.How to reduce and eliminate new clothes build the room air pollution of building become people pay close attention to hot issue.
Nanometer anatase titania is the photochemical catalyst that it is found that in recent years the organic volatile of can effectively degrading, and especially the degradation effect of PARA FORMALDEHYDE PRILLS(91,95) is better.The existing example of using it in air-conditioning filter net or being added on coating for wall surface at present, but air conditioning filter web area is less, the effect purifying air is limited, in coating for wall surface, add photochemical catalyst, due to coated to photochemical catalyst of coating, make the surface of TiO 2 particles cannot directly contact organic volatile.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of preparation method with the wallpaper of formaldehyde and organic volatile effect in photocatalytic degradation of indoor air.
In order to solve the problems of the technologies described above, the preparation process of wallpaper of the present invention is as follows:
Step 1: the wallpaper of selecting finished product is raw material, first applies one deck aqueous high molecular glue on wallpaper surface; After this glue drying and forming-film, there is high transparent, do not affect printing decorative pattern and the color of former wallpaper.
Step 2: spray and there is the titanic oxide nano powder of photo-catalysis function on macromolecular liquid glue, or titanic oxide nano powder is configured to dispersion liquid sprays;
Step 3: wallpaper is put into drying tunnel and dry, the bottom of titanium dioxide granule is bonded together by macromolecule transparent adhesive tape and wallpaper.
Described in step 1, the wallpaper base material of finished product adopts PVC base material, non-woven fabrics base material, calcium carbonate-filled polyolefin (or claiming stone paper) base material or body paper base material.
Described in step 1, aqueous high molecular glue adopts the one in acrylate copolymer emulsion glue, ethene-vinyl acetate copolymer emulsion glue or aqueous polyurethane glue.
The thickness of the macromolecule transparent adhesive film described in step 1 is 10-25 μ m, by concentration and the coating thickness of transparent adhesive tape, regulates.
The titanic oxide nano described in step 2 with photo-catalysis function is that anatase crystal type or sharp titanium are the titanium dioxide powder of 5-50 nanometer with rutile mixing crystal formation, average grain diameter.The less photocatalysis effect of titanium dioxide powder average grain diameter is better.
The quantity for spray described in step 2 with the titanic oxide nano of photo-catalysis function is 0.1-1g/m
2.
Titanium dioxide optical catalyst powder dispersion liquid described in step 2, dispersion liquid mass percent concentration is 10%-25%, dispersion liquid sprinkling amount is 2g/m
2-3.5g/m
2.
Preferably, it is the ethene-vinyl acetate copolymer emulsion that 20-25 μ m solid content is 48% that the surface of wallpaper applies a layer thickness, then at this coating surface, spraying average grain diameter is the 50 sharp titaniums in nanometer left and right and rutile mixing crystal formation titanium dioxide optical catalyst powder dispersion liquid, dispersion liquid mass percent concentration is 20%, and dispersion liquid sprinkling amount is 2.5g/m
2.
By above-mentioned preparation method, employing wallpaper is carrier, first on wallpaper surface, apply one deck macromolecular liquid transparent adhesive tape, after this glue drying and forming-film, there is high transparent, do not affect printing decorative pattern and the color of former wallpaper, then on macromolecular liquid glue, spray titanic oxide nano or the dispersion liquid with photo-catalysis function, again wallpaper being put into drying tunnel dries, can make the bottom of titanium dioxide granule be bonded together by macromolecule transparent adhesive tape and wallpaper, and the most surfaces of titanium dioxide granule still keeps reset condition, do not have binding agent coated, there is very high photocatalytic activity, there is the effect that PARA FORMALDEHYDE PRILLS(91,95) and organic volatile decompose.
