Description

A kind of manufacture method of novel wallpaper

Technical field:

The present invention relates to the converted paper of interior decoration, the manufacture method of a kind of novel wallpaper of saying so more specifically.

Background technology:

Along with modern people's growth in the living standard and requirements at the higher level that living environment is beautified, the indoor wall ornament materials more and more is subject to people's attention.And wallpaper is environment friendly and pollution-free owing to be a kind of novel, elegant in appearance and color kind purposes diversity and be subjected to liking of people.Wallpaper belongs to the decorative kind converted paper, is mainly used in the decoration of the metope of hotel, restaurant, shop, meeting room and household etc.External novel wallpaper such as heating installation wallpaper, the desinsection wallpaper is inhaled the flavor wallpaper, and the wallpaper of reporting a fire, anti-eavesdrop wallpaper, high shielding wallpaper etc. all are that people's life has increased many convenience.

The wallpaper rich color also is furnished with very pattern of different texture, and its decorative effect is very good.And general import brand wallpaper all also has the senior designer to design different style wallpaper according to bedroom, living room, dining room, children room etc. to select for everybody that (these wallpapers that are applied to chummery not generally in the sample of corresponding classification, make things convenient for everybody to select.Such as having children room wallpaper version under the brand, kitchen, dining room version or the like, it is selective to have hundreds of different patterns in each version).Colored type, color and the texture of these wallpapers is all arranged in pairs or groups very perfectly, as long as we choose subsides in the own home, effect has just been come out.Be equivalent to design the metope of your family by real senior Specialty Design teacher.And the wallpaper pattern is thousands of, seldom can repeat with others' family, also allows you that family of rich individual character is arranged.The style of wallpaper ever-changing one is mentioned wallpaper, a lot of people always think that wallpaper is all colored, seem to feel dizzy, and this mainly is that the wallpaper that everybody sees is the engineering wallpaper in places such as Karaoke, restaurant mostly, so pattern is relatively exaggerated, it much is very plain having in the wallpaper in fact.Ou Mei some wallpapers particularly, what emphasize mainly is the sense of texture of wallpaper, and wink is very light, and it is very graceful to stick wall.The wallpaper of country variant has different styles, and in general Korea S's wallpaper relatively is fit to modern and brief style; The U.S., Canadian wallpaper are fit to American, rural style; Japan's wallpaper is fit to the style of sweet warmth; Italian, Belgian wallpaper is fit to gorgeous, luxurious decoration style or the like.When selecting wallpaper, though different room patterns is all different, but must get hold of whole style, unified as far as possible, the assurance of this and whole decoration style is the same, not talkative room is designed to European allusion, and the another one room is designed to modern brief, and whole structure like this can can't get out.

Improving constantly of the progress of science and living standard promoted the fast development of building and ornament materials industry.Except many kinds of product, many specifications, outside the development of conventional idea such as multi-color, ornament materials in recent years has the following development characteristic: because modern architecture develops to high level, the unit weight of material has been had new requirement.From ornament materials use the material aspect, use the light-weight high-strength material as aluminium alloy so more and more.From process aspect, take hollow, interlayer, form such as cellular are made the ornament materials of high-strength light.In addition, adopting high strength fibre or polymer and common material compound, also is raising ornament materials intensity and reduce the method for its weight.As aluminium alloy extrusions, magnadure clad can fiberboard, the artificial marble used in recent years, products such as hollow vitreous brick promptly are examples.

Coated glass, double glazing, laminated glass, heat-reflecting glass that development in recent years is exceedingly fast have not only been regulated indoor light, have also cooperated indoor air conditioning, have saved the energy.Various expansion types, foam type acoustic board and even acoustic paint have not only been decorated indoorly, have also reduced noise.Be commonly used for the soft sound absorption ornamental hard board of furred ceiling in the past, and replaced by mineral wool sound absorption board gradually, reason is that the latter has extremely strong fire resistance.For modern high-rise building, fire line has been one of indispensable index of ornament materials.Decorative wall paper commonly used, now also had antistatic, anti-pollution, report a fire, anti-x ray, anti-ly damage by worms, the multiple model of deodorization, difference in functionality such as heat insulation.

Wallpaper similarly is the full dress of household metope, allows whole family all be full of lively expression.Especially personalized and high-quality finishing, novel wallpaper all has the unapproachable effect of interior wall coating on texture, decorative effect and practicality.According to external scholarly forecast, in 20 years to 50 years from now on, wallpaper will be the main material of interior decoration.Wallpaper is for being bonded into film with resin, plastics, and adding filler, pigment and other complementary raw material are made into the water fever tex, adopt air knife or print roll coating method again and roll compound, method such as calendering foaming etc. to combine, process through the fine arts such as embossing, stamp or foaming decoration again with body paper.The designs and varieties of wallpaper are various, but will there be performances such as excellent waterproof, anticorrosive, wear-resisting wiping on total wallpaper surface that requires.
