Abstract

The utility model provides an environment-friendly polyethylene glycol terephthalate (PET)-polyvinyl fluoride (PVF) bright film and relates to a decorative protective film compounded on a metal board or a building material. A bottom layer plastic film layer, a coloring layer, an adhesive layer, a printing layer and a PET film layer are superposed and arranged sequentially; the bottom layer plastic film layer is a PVF film and can protect the surface of the metal board from being rusted easily and the decorative surface from being faded or embrittled; and metal is isolated from air by using the sealing property of the film, so a complete corrosion-resistant effect is achieved. Besides, the film can be printed with various patterns and colors as required, the surface of the film has various types of glossiness, and by adoption of the film, colorful decorative effects can be displayed.

Description

Environment-friendly PE T-PVF light film

Technical field

The utility model relates to a kind of decoration diaphragm that is compound on sheet metal or the construction material, refers in particular to a kind of PET-PVF light film of environment-friendly type.

Background technology

Chinese patent CN03220678.X discloses the high bright film of a kind of PET-PVC, and the PVC film is provided with dyed layer, and dyed layer is provided with adhesive; Adhesive is provided with pearl layer, and pearl layer is provided with patterned layer, and patterned layer is provided with the PET film; The PET film is provided with aging layer, and aging layer is provided with diaphragm, and the base material of this bright film adopts the PVC material; VCM residual in the PET-PVC structure is acknowledged as carcinogenic substance, and PVC when burning amount of being fuming is very big, if incineration temperature is lower than 800 ℃; The chloride rubbish imperfect combustion of plastics and so on very easily generates dioxin, contaminated environment.For meeting environmental protection requirement in the industrial policy, market demand is sought the substitute of some new degradation plastics as PVC, and occurring in succession on the market with PP, PET is the bright film of base material (counterdie).

Summary of the invention

The purpose of the utility model provides a kind of bright film of environmental protection, and it is posted at material surfaces such as flat cold-rolled sheet, aluminium sheet, galvanized sheet, aluminium plating zinc plate, decorative panel, construction materials, rises and decorates protective effect, and can improve the physics and the chemical property of original substrate.Main innovation is that base material (counterdie) adopts PVF (polyvinyl fluoride) film.

Specifically implement like this: environment-friendly PE T-PVF light film; Bottom plastic membranous layer, dyed layer, adhesive phase, printed layers, PET film (PETG) layer stratiform stack are successively arranged, and it is characterized in that the bottom plastic membranous layer is PVF (polyvinyl fluoride) film.The PVF film, formal name used at school polyvinyl fluoride (polyvinyl fluoride) is formed by the extruding of the EVA of fluorine and fluorine carbon molecule, has bigger chemical bond power and structural stability than other any polymer.This is a kind of high bright film product, and bottom is the PVF film, and is painted on the PVF film, coating adhesive on dyed layer; Printed patterns on the PET film is bonded together PVF counterdie that scribbles adhesive and the PET film that is printed on pattern then.

The utility model can also be provided with one deck delustring layer on the PET film, form a kind of matt effect, can also in adhesive, add pearl essence, and making the adhesive layer on the dyed layer is the mixed layer of adhesive and pearl essence, forms the bright film of a kind of pearly-lustre.

Also be equipped with diaphragm on the upper space of the utility model light film, guarantee that product quality is better.

In the utility model product, the PVF film can not react with the pollution factor in the atmosphere, even the very strong solvent of corrosive power can not cause damage to it yet, thereby is protected metal sheet surface to be difficult for corrosion, combination with decorative surfaces not fugitive color or embrittlement; The PVF film can not receive ultraviolet intensifying and the variation that produces institutional framework, and Exposure to Sunlight can not quickened it and " wear out "; The PVF film can be because of the variation of the formative tissue of the circulation change repeatedly structure of operating ambient temperature, and the temperature change value that working environment is allowed is 180 ℃, and (70～+ 110 ℃) almost can adapt to the outdoor environment of all regions on the earth.The PVF film has bigger toughness, and percentage elongation does not have crackle with the magnifying glass observation film surface of amplifying 43 times after can reaching 100%, 180 degree folding test; The PVF film can bear various operations such as shearing, punching press, roll extrusion, boring, ailing, edging and flanging and do not produce the be full of cracks or other possibly influence the infringement in service life.The steel plate combination with decorative surfaces that the PVF film pastes is more careful attractive in appearance; Fine and close PVF film surface is difficult for staiing, and is almost non-maintaining under the normal condition; Do not contain the environment of any support microorganism or fungus growth in the smooth thin clean PVF film, do not allow bacterial penetration fully; General water dashes and can satisfy the cleaning requirement.

This product can be laminated with at material surfaces such as flat cold-rolled sheet, aluminium sheet, galvanized sheet, aluminium plating zinc plate, decorative panel, construction materials; Technology is simple; Easy to operate, utilize close property of film to make metal and air is isolated plays complete antisepsis, this film can print various patterns and color as required; And there is multiple glossiness on the surface, shows colourful decorative effect.
