Technical field

A kind of decoration diaphragm being compound on sheet metal or construction material is the utility model is related to, refers in particular to one kind The PET-PE bright films of environment-friendly type.

Background technology

Chinese patent CN03220678.X discloses a kind of high bright films of PET-PVC, and PVC film is provided with dyed layer, coloring Layer is provided with adhesive, and adhesive is provided with pearl layer, and pearl layer is provided with patterned layer, and patterned layer is provided with PET film, PET film Aging layer is provided with, aging layer is provided with diaphragm, and the base material of this bright film uses PVC material, remained in PET-PVC structures VCM be acknowledged as carcinogenic substance, and smoke amount is very big when PVC burns, if incineration temperature is less than 800 DEG C, plastics it The chloride rubbish imperfect combustion of class, dioxin is easily generated, pollute environment.To meet requirement environmentally friendly in industrial policy, city Field needs to find some substitutes of environmentally friendly, new, degradation plastic as PVC, and in the market also occurs much with environmental protection in succession Material is base material（Counterdie）Bright film.

The content of the invention

The purpose of this utility model is to provide a kind of environmentally friendly bright film, and it is posted in flat cold-rolled sheet, aluminium sheet, zinc-plated The material surfaces such as plate, aluminium plating zinc plate, decorative panel, construction material, decoration protective effect is played, and physics and the change of original substrate can be improved Learn performance.Main innovation is base material（Counterdie）Using PE plastics（Polyethylene）Film, while set between printing layer and PET film layer There are NiCrAlY film layers, NiCrAlY films have the characteristic of preferable high temperature resisting corrosion resisting, therefore enhance of the present utility model anti- Anti-corrosion property at high temperature.

It is specific to be such to what is implemented：Environment-friendly PE T-PE bright films, including bottom plastic film layer, dyed layer, adhesive Layer, printing layer, PET film（Polyethylene terephthalate）Layer stratiform superposition arrangement successively, it is characterised in that bottom plastic foil Layer is PE films（Polyethylene）.PE plastics（Polyethylene）It is that odorless, tasteless, nontoxic combustibility is white for typical thermoplastic Color powder.Polyethylene fusing point is that 100-130 DEG C of its resistance to low temperature is excellent.Good mechanical property can be still kept at -60 DEG C Can, but temperature in use is at 80 ~ 110 DEG C.PE films（Polyethylene）Chemical stability is preferable, be resistant at room temperature dust technology, dilute sulfuric acid and The hydrochloric acid of any concentration, hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammoniacal liquor, amine, hydrogen peroxide, sodium hydroxide, potassium hydroxide etc. are molten Liquid.This is a kind of high bright film product, and bottom is PE films, is coloured on PE films, the coating adhesive on dyed layer；In PET film Printed patterns, then the PE counterdies and the figuratum PET film of print that scribble adhesive are bonded together.

Preferably, the bottom plastic film layer is PE plastic foils, the PE plastic foils be linear low density polyethylene (LLDPE) or Linear low density polyethylene (LLDPE) and low density polyethylene (LDPE) mixture；Described adhesive layer is the mixed layer of adhesive and pearl essence, institute It is polyurethane binder to state adhesive, and the bottom plastic film layer and PET film thickness ratio are 2:1.

Preferably, NiCrAlY film layers are additionally provided between the printing layer and PET film layer.

Preferably, the thickness of the bright film is 0.5mm ~ 1.0mm.

Preferably, the dyed layer and printing layer thickness are respectively less than 0.3mm, decorative pattern is printed in the printing layer.

Preferably, being provided with one layer of extinction layer in the PET film, the extinction layer color is white.

Preferably, add matcoveredn on the upper space of the bright film.

The beneficial effects of the utility model：The utility model product has high-environmental quality, will not decompose and go mouldy, Harmful substance volatilization is not had, and chemical property is stable.In process of production, using environment-friendly type raw material, do not produce harmful gas simultaneously, Recoverable, NiCrAlY film layers are provided between printing layer and PET film layer, add the high temperature resistance and corrosion resistance of this product. This product can be with laminating in the material surfaces such as flat cold-rolled sheet, aluminium sheet, galvanized sheet, aluminium plating zinc plate, decorative panel, construction material, technique Simply, it is easy to operate, cause metal and air exclusion to play complete antisepsis using close property of film, the film can be according to need Various patterns and color are printed, and surface there are a variety of glossiness, shows colourful decorative effect.
