Novel PET (polyethylene terephthalate) symbiotic material for aluminum foil compounding

Technical Field

The utility model relates to the technical field of aluminum foil composite materials, in particular to a novel PET (polyethylene terephthalate) symbiotic material for aluminum foil composite.

Background

The PET intergrowth material compounded by the aluminum foil is an aluminum foil material compounded by the PET intergrowth material, and because the aluminum has soft texture, good ductility and silvery white luster, if the rolled sheet is pasted on offset paper by using sodium silicate and other substances to prepare an aluminum foil sheet, the printing can also be carried out. However, the aluminum foil is easily oxidized, becomes dark in color, and fades when being rubbed, touched and the like, so that the aluminum foil is not suitable for hot stamping of book covers and the like which are stored for a long time, and the aluminum foil is widely used for food, beverages, cigarettes, medicines, photographic bases, household daily necessities and the like due to the excellent characteristics of the aluminum foil and is generally used as a packaging material of the aluminum foil; an electrolytic capacitor material; heat insulating materials for buildings, vehicles, ships, houses, and the like; it can also be used as decorative metallic lines, wallpaper, various stationery printed matters, and decorating trademarks of light industry products.

Although the performance of the aluminum foil composite material PET intergrowth material is gradually improved in the actual use process, problems to be solved still exist, for example, the composite aluminum foil using the PET intergrowth material is easily oxidized in the actual use process, so that the surface color of the aluminum foil is blackened, the attractiveness of the composite aluminum foil is greatly reduced, and meanwhile, the strength in the use process is lower.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems of easy oxidation and low strength of the aluminum foil composite material and achieve the purposes of good oxidation resistance and high strength, the utility model is realized by the following technical scheme: the utility model provides a novel be used for compound PET intergrowth material of aluminium foil, includes the inlayer, the surface of inlayer is provided with the enhancement layer, the outside of enhancement layer is provided with the viscose layer, the outside on viscose layer is provided with the aluminium foil layer, the outside on aluminium foil layer is provided with the inoxidizing coating.

Further, the main material of the inner layer is PET plastic.

Furthermore, the reinforcing layer is formed by weaving metal wires in a cross shape in a warp-weft crossed manner, so that the strength of the composite aluminum foil material is better.

Furthermore, the main material on viscose layer is polyvinyl chloride resin material, the viscose layer is soft glue film for the adhesive property on viscose layer is better and can not exert an influence to the pliability of compound aluminium foil.

Furthermore, the quantity of enhancement layer the viscose layer the aluminium foil layer and the inoxidizing coating is two respectively and equal symmetric distribution is at the upper and lower both ends of inlayer for composite aluminum foil material's wholeness can be better.

Furthermore, the protective layer is a Cr-N film with a CrN structure, so that the composite aluminum foil material has better oxidation resistance, and the condition that the surface color of the aluminum foil is blackened due to oxidation on the surface of the aluminum foil is avoided.

The utility model provides a novel PET intergrowth material for aluminum foil compounding. The method has the following beneficial effects:

1. according to the novel PET intergrowth material for aluminum foil compounding, the Cr-N film with a CrN structure is used as the protective layer, so that the oxidation resistance of the surface of the composite aluminum foil is greatly improved, the condition that the appearance of the composite aluminum foil is greatly reduced due to the fact that the surface of the composite aluminum foil is gradually blackened due to oxidation in the use process of the composite aluminum foil is avoided, the chemical stability of the composite aluminum foil in the actual use process is better, and the actual use requirement can be met;

2. this novel PET intergrowth material for aluminium foil complex, through the design of enhancement layer for the intensity of composite aluminium foil in the in-service use process is better, thereby composite aluminium foil's usage is more extensive, makes composite aluminium foil physical stability in the use better, simultaneously, through the design on viscose layer, makes the bonding effect between each layer of composite aluminium foil better, thereby makes composite aluminium foil be difficult for appearing the condition of layering in the in-service use.
