Description
Technical field
The utility model relates to the high imitative metal wire-drawing VCM film of a kind of BOPET.
Background technology
Non-ferrous metal, nonmetal plate and non-ferrous metal and composite non-metal sheet material, owing to economizing on resources, being easy to processing, with low cost, the application in industry and life is more and more general.Particularly the application of thin plate is more extensive, and the furniture of automobile, refrigerator, washing machine, elevator wallboard and top grade and room division board etc. all will use.Be all print again after the shape that sheet material is processed into requirement or spray to obtain appearance attractive in appearance the earliest, but the appearance that this nonplanar printing and spray process obtain is limited, technology is complicated and not environmental protection of technical process.In recent years in the household electrical appliance industry, rise gradually at the surface of steel plate composite plastic film and substitute the sheet metal with special decoration appearance characteristics, can not only play protective action, also has decoration function, has good appearance, regrettably plastic foil when producing multicolour and pattern, has also hidden the gloss of metal, has lost the peculiar texture of metal material.
At present, be used for the stainless steel wire drawing plate, fine aluminium bushing, titanizing wire drawing steel plate of family expenses panel etc., its material price is higher, has therefore restricted it and has applied.
Patent 201110365769.X discloses a kind of imitative aluminium wiredrawing composition membrane, comprises PET rete, adhesive phase, PVC rete and wire drawing aluminium foil layer.Another kind of technical scheme replaces the PVC rete with the PET rete.This imitative aluminium wiredrawing composition membrane has metallic luster and the wire drawing texture of wire drawing aluminum, simultaneously due to wire drawing paper tinsel layer between PET rete and PVC rete, therefore, can starvation, anti-oxidation, realize permanent keep the wire drawing aluminium foil metallic luster and wire-drawing effect; Should can further be compound in flat cold-rolled sheet, aluminium sheet, galvanized sheet, building material surface by imitative aluminium wiredrawing composition membrane, and play a part to decorate protection and attractive in appearance, technique is simple, easy and simple to handle, cost is low.
Patent 201110357527.6 discloses a kind of artificial stainless steel composite membrane with wire-drawing effect, comprises metal aluminum foil layer, PET rete, PVC rete, printing color layer and the protective layer that process through wire drawing on the surface.This artificial stainless steel composite membrane has very strong stainless steel wire drawing gloss, and the artificial stainless steel degree is high, and metallic luster is lasting, is applied on household electrical appliances, cooking apparatus to make it more attractive in appearance, improves product specification.
But above-mentioned two patents all adopt the trilaminate material complex technique, and technology is complicated, and is still very large to the energy and raw-material consumption demand, and are limited in the progress of the aspect such as energy-conservation, as to economize on resources; And owing to having used aluminium foil, because aluminium foil belongs to non-feature of environmental protection composite, so product does not possess environment-friendly function.
Number of patent application 201020640194.9 discloses a kind of stainless steel wire drawing plate.This is a kind of PCM precoating plate, and base material adopts corrosion resistant plate, carries out wire drawing with wire-drawing equipment, the surface roller coating finishing oil.Pencil hardness is greater than HB, and the cupping performance can be rushed dark 8mm, and combination property reaches conventional precoating product requirement comprehensively.But; this patent is large to corrosion resistant plate consumption demand; not only cost of material is high; compare simultaneously and carry out the wire drawing processing on plastic sheeting; carry out on corrosion resistant plate the wire drawing intractability larger, protect more difficult realization; therefore cost is very high, its production technology neither energy-conservation, economize on resources, also not environmental protection.
The utility model content
Technical problem to be solved in the utility model be to have overcome existing imitative metal wire-drawing composite film material consumption large, not energy-conservation, economize on resources, the also defective such as not environmental protection and production cost height provides the high imitative metal wire-drawing VCM film of a kind of BOPET.
The utility model is to solve above-mentioned technical problem by following technical proposals: the high imitative metal wire-drawing VCM film of a kind of BOPET, it comprises a hard surface coating successively, one single face carried out the transparent BOPET film that surperficial wire drawing is processed, and one strengthens fastness coating, a vacuum aluminium coated layer and an anti-oxidation protection coating; The one side of wherein processing through surperficial wire drawing in this BOPET film is connected with this enhancing fastness coating, and the one side of not processing through surperficial wire drawing is connected with this hard surface coating; This hard surface coating is the polyurethane ultraviolet curing dope layer; This enhancing fastness coating is the polyurethane coating layer, and this anti-oxidation protection coating is the polyurethane coating layer.
