Description

Gild firm film and wall of color skill nano-negative ion function Buddha's warrior attendant film, wall pastes adamantine plate
Technical field
The utility model belongs to indoor wall wallpaper (film) field, particularly relates to a kind of color skill nano-negative ion function Buddha's warrior attendant film, firm film gilded by wall and wall pastes adamantine plate.
Background technology
At present, the material with function and for indoor wall decoration is mainly coating for wall surface, and it is added with the additive of this type of effect when manufacturing coating, only need add being uniformly mixed in proportion, whole production technology and manufacture process fairly simple.But this coating only has monochromatic allotment, can not produce pattern effect, more can not produce 3D anaglyph and the have levels marble and other floral designs felt, therefore generally be only applicable to wall body decoration.Though some commercial coating products is containing anion, can not anion releasing for a long time, reason is that anion is contained easily to concentrate on most top layer and discharged and impairedly to come off; And the tourmaline composition realizing anion function more easily produces micro-radiation on surface, is unfavorable for health, its wear-resisting scratch-resistant clean-up performance is general.In addition, construction in later period operation complexity is loaded down with trivial details, and labour cost is expensive, long construction period, causes overall cost higher, therefore also for body of wall, can only can not be applied to the incrustation of the materials such as various sheet metal and woodwork.Existing wallpaper product there is no method and realizes including anion, and surface is not wear-resisting not scratch-resistant, can not shampoo, and easy xanthochromia goes rotten.
Tourmaline is Yunnan Province of China, the distinctive Gem Grade mineral reserve in Xinjiang region, and it has unique pyroelectric effect, during energy around accepting, it can exchange with ambient energy, ionization ambient air, excites electronics in air to release, thus generation anion, i.e. negative aeroion.Negative aeroion is described as air vitamin or auxin, has great effect to health, and the air containing negative aeroion is the comfort air that the mankind are produced refreshing effect to the mind.
Utility model content
The technical problems to be solved in the utility model is to provide advanced, the scientific and reasonable for structure color skill nano-negative ion function Buddha's warrior attendant film of a kind of manufacturing process, firm film gilded by wall and wall pastes adamantine plate, products obtained therefrom has the scratch-resistant feature easy to clean of surface abrasion resistance, and including the long-acting release of anion energy, environmental protect is remarkable with guarantee health efficacy.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: color skill nano-negative ion function Buddha's warrior attendant film, is made up of successively from top to bottom nanoscalar uv top coat layer, attachment dielectric layer, PET facial mask/gloss application sheet facial mask/stone paper, attachment dielectric layer, printing pattern layer, nano-negative ion compound adhesive water layer and nano-negative ion plastic bottom membrane equilibrium layer or glass fabric.
Color skill nano-negative ion functional wall is gilded firm film, is pasted non-drying glue layer and is formed from shape layer paperboard/mould release membrance successively from top to bottom by nanoscalar uv top coat layer, attachment dielectric layer, PET facial mask/gloss application sheet facial mask/stone paper, attachment dielectric layer, printing pattern layer, nano-negative ion compound adhesive water layer, nano-negative ion plastic bottom membrane equilibrium layer or glass fabric, powerful body of wall.
Color skill nano-negative ion functional wall pastes adamantine plate, is pasted non-drying glue layer and is formed from shape layer paperboard/mould release membrance successively from top to bottom by nanoscalar uv top coat layer, attachment dielectric layer, PET facial mask/gloss application sheet facial mask/stone paper, attachment dielectric layer, printing pattern layer, nano-negative ion compound adhesive water layer, nano-negative ion plastic bottom membrane equilibrium layer or glass fabric, PUR polyurethanes reaction type hot-fusible glue-line, metal or nonmetal plate, powerful body of wall.
For current coating for wall surface and wall paper (film) Problems existing, in conjunction with pyroelectric effect and the function exciting generation negative aeroion of crude tourmaline uniqueness, inventor has designed and produced a kind of color skill nano-negative ion function Buddha's warrior attendant film, is made up of successively from top to bottom nanoscalar uv top coat layer, attachment dielectric layer, PET facial mask/gloss application sheet facial mask/stone paper, attachment dielectric layer, printing pattern layer, nano-negative ion compound adhesive water layer and nano-negative ion plastic bottom membrane equilibrium layer or glass fabric.On this basis, also extend gild firm film and wall of the wall with said function and paste adamantine plate.Negative ion generating material is made nano-negative ion compound adhesive water layer and nano-negative ion plastics counterdie and the layer that its compound is clipped in the middle by the utility model products obtained therefrom in advance, both tourmaline difficult drop-off, permanent existence also long-acting negative ion release had been conducive to, the adverse effect of micro-Radiation On Human body can be intercepted again, kill two birds with one stone, being a manufacturing process advanced person, brand-new wall paper (film) product scientific and reasonable for structure, is that other walls paste product, wallpaper cannot match in excellence or beauty.
Experiment shows, color skill nano-negative ion function Buddha's warrior attendant film of the present utility model, wall gild that firm film and wall paste that adamantine plate surface abrasion resistance is scratch-resistant, scrubbing resistance, color inhibition, without going mouldy, be not afraid of humidity, can high temperature resistant 120 DEG C and fire-retardant and low temperature resistant-40 DEG C, wall pastes and firmly, not peels off, long-term indoor use non yellowing.Owing to including the functional material of long-acting release nano-negative ion, the utility model product just can long-acting negative ion release without the need to electricity consumption oxygen, by anion environmental protect: decompose and remove pernicious gas, removing flue gas fresh air, the pernicious gases such as the newly-decorated indoor formaldehyde of accelerated decomposition; Meanwhile, anion also can improve microcirculation in human body, develop immunitypty, reduces architectural decoration to human injury, effectively eliminates air conditioner comprehensive disease.Therefore, the utility model product can be widely used in indoor wall decoration, lift car decoration, traffic car, boats and ships, train interior trimming decoration etc.
