The manufacture method comprises the following characteristics that: 1, the wallpaper is produced by using the known rolling process productive technology; 2, a wallpaper laminated structure comprises a protective layer and a paper layer according to the top down sequence, the protective layer and the paper layer are adhered by using an adhering agent; 3, design and color patterns of the wallpaper are printed on the paper layer; and 4, a nano titanium dioxide photochemical catalyst is added in the protective layer of the wallpaper, formaldehyde and volatile organic compounds (VOC) are decomposed by using a photocatalysis principle, bacteria are killed and bacterium bodies can be decomposed. The sterilization formaldehyde-removing wallpaper manufactured by using the method has the advantages of simple production process, simple laminated structure and low production cost, and has a function of purifying air, such as sterilizing, removing formaldehyde and the like; the cleanness of the wallpaper can be kept a certain extent, and frequent cleaning is not needed, thus the wallpaper has a certain self-cleaning function. Proved by sterilization experiments, the wallpaper has bacterium killing rate reaching 60 percent when being irradiated by natural light.
Description
Technical field
The present invention relates to a kind of manufacture method of sterilization aldehydes removal wallpaper, belong to functional building and ornament materials manufacturing technology field.
Background technology
Wallpaper claims wallpaper again, a kind of special processing paper that is used for decorative wall.The cradle of wallpaper is in Europe, and the most universal in Northern Europe developed country now, environmental protection and quality are best, secondly are countries in Southeast Asia, Japan, Korea S's wallpaper popularity rate also up to nearly 90%.
Wallpaper generally all is composited by adhesive by protective layer, printed layers, supporting layer, paper substrate, because industrial chemicals such as a large amount of use adhesive, a large amount of formaldehyde volatilize from glue-line and go out, and room air is produced severe contamination.Two seasons of summer in winter are that air-conditioning uses peak season, also are indoor bacteria and viral most active season, and people are very easy to infect various epidemic infectious diseases; People often are easy to generate volatile organic contaminants such as a large amount of formaldehyde, benzene, Ammonia after buying new home finishing, all to the serious hidden danger of the healthy generation of resident.It is long-pending that the tradition wallpaper has occupied interior decoration space exhibiting high surface, yet but can't utilize surface area that room air is purified, and this is a kind of sorry of wallpaper application always.
The photocatalyst English name is: Photocatalyst is the compound word of light " Photo "+catalyst " catalyst ".Utilize the photocatalyst technology luminous energy can be converted into chemical energy, organic molecules such as the formaldehyde in atmosphere or even the water environment, acetaldehyde, ammonia decomposed, be decomposed into nonpoisonous and tasteless carbon dioxide and water, become environmental improvement one sharp weapon.In essence, photocatalyst is exactly the semi-conducting material with photo-catalysis capability, when the irradiation that is subjected to more than or equal to the light of its energy gap, just can excite to generate electronics e-and hole H+, these electronics and hole are exactly the active material of light-catalyzed reaction, especially hole, has very strong oxidability, not only can oxidation of formaldehyde, polluters such as benzene class, Ammonia, can also oxidation and kill bacteria, and decompose its corpse of degraded.In all photocatalysts, titanium dioxide is because the catalytic activity height, and safety non-toxic, stable, the environmental friendliness of chemical property are with low cost, the mineralization rate height, and advantages such as non-secondary pollution become the environment-friendly type catalysis material of the tool exploitation future in environment pollution treatment field.
Sterilization aldehydes removal wallpaper involved in the present invention; creationary in the photocatalyst material adding wallpaper protective layer, production technology is simple, has effectively utilized the surface area of wallpaper; kill bacteria and organic volatile (VOC) make wallpaper possess self-cleaning function to a certain degree rapidly.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of sterilization aldehydes removal wallpaper.
A. wallpaper production technology:
Adopt known rolling process production technology.
Be contained on the uncoiler the inorganic mineral paper of printed pattern is counter, with the paper substrate preheating, by the adhesive dipping tank gluing of EVA or LDPE, use the acrylic resin overlay film that adds nano titanium oxide and coupling agent Si-69 at last through 40-60 ℃ preheat roll then, 60-80 ℃ of oven dry, cooling.
B. wallpaper structure:
(1) protective layer is an acrylic resin, and the protective layer film is made of acrylic resin, nano titanium oxide, coupling agent Si-69, and each composition quality percentage is:
Acrylic resin, 50-61%;
Nano titanium oxide, 37-48%;
Coupling agent Si-69,1-2%.
Wherein, the content of nano titanium oxide is if be higher than 48%, and then the acrylic resin film clarity is affected; If the content of nano titanium oxide is lower than 37%, then photocatalysis efficiency reduces, and decomposes the ability drop of organic volatile contaminant molecule.
(2) protective layer and paper substrate are by adhesive bonds, and used adhesive is " ethylene-vinyl acetate copolymer resin (EVA) ".In EVA, the vinyl acetate mass percentage content is 20%, and melt flow index is 5g/10min.
C. the preparation of acrylic resin film:
(1) gets 40g polypropylene monomer,, add 0.64gSi-69, stir 60 ℃ of following fusions; Add the 24g nano-titanium dioxide powder again, stir.The titanium dioxide powder particle diameter is 20nm, can select the safe product in sea, Nanjing for use, and product type is HTTi, and particle diameter is 10～40nm, purity 99%; Other rutile type nano titanic oxide also has the part photocatalysis performance, but decompose and degradation efficiency slightly a little less than.
(2) molten mass that generates in (1) is cooled to 40 ℃, last extruder charges into compressed air by O font mould mouth behind the shape film forming pipe in the film pipe, make the outside prolonged expansion film forming of film pipe.
Characteristics of the present invention are: production technology is simple, adopts known rolling process to produce wallpaper; In protective layer, add the photochemical catalyst nano titanium oxide; the color and the outward appearance that had both kept wallpaper; increase the function of wallpaper sterilization and decomposing organic pollutant again, made wallpaper in interior decoration, bring into play the effect that purifies the air of a room, possessed certain self-cleaning function.
The present invention compared with prior art has following remarkable advantage:
The present invention has utilized wallpaper to have the characteristics of big swap table area in the interior space; the photochemical catalyst nano titanium oxide is widely distributed in the wallpaper protective layer; fully contact with room air; kill airborne bacterium and virus; decompose airborne organic contamination volatile matter (VOC), reach the effect that purifies air.
