Abstract
A method for preparing PVC (polyvinyl chloride) aluminized film comprises the following steps: spreading a separating agent onto a carrier film, putting aluminum into an evaporating boat, unrolling, performing vacuum aluminizing on the surface of the carrier film, coating the surface of the carrier film with an adhesive, and compounding with a PVC film, drying, separating, and removing the carrier film, wherein the method is characterized in that during direct vacuum aluminization on the surface of the carrier film, the vacuum degree is (1-1.2)* 10 <-2> Pa and the temperature inside the evaporating boat is 1410-1450 DEG C. The vacuum degree, the temperature and the unrolling speed during the vacuum aluminization on the surface of the carrier film are properly selected, so that aluminum vapor after aluminum evaporation can be more uniformly adhered to the surface of a carrier, with good combination degree with the carrier, and thus when the carrier surface is removed after the carrier is compounded with the PVC film, the obtained PVC aluminized film is good in color and quality and high in adhesive force; the separating agent and the adhesive which are used in the method are relatively low in price, so that the production cost is reduced and the productivity effect is improved.
Description
Technical field
The present invention relates to a kind of manufacture method of aluminizer, particularly a kind of manufacture method of PVC aluminium coating film.
Background technology
Aluminizer is a kind of composite soft packaging material that adopts special process to form at metallic aluminium as thin as a wafer of plastic sheeting plated surface last layer, wherein the most frequently used processing method is when the vacuum aluminum-coated method of number, be exactly by high temperature, metallic aluminium to be melted to evaporation under high vacuum state, the steam precipitation of aluminium is stacked on plastic sheeting surface, thereby makes plastic sheeting surface there is metallic luster.Because it had both had the characteristic of plastic sheeting, there is again the characteristic of metal, be that a kind of cheapness is attractive in appearance, function admirable, practical packaging material.
Transfer method vacuum aluminized film is the new technology that grows up plastic sheeting is aluminized in the vacuum aluminum-coated technology of direct method and Equipment Foundations. its production process can be divided into following a few step: 1, in carrier film, step on deposited release agent; 2, directly vacuum aluminum-coated; 3, binding agent is coated in carrier film surface, then carry out compound with other base material; 4, layering is shifted.After oven dry, because the aluminium coated on carrier and Ji Shu are bonded together securely, thus again that carrier film is separated, can obtain the vacuum aluminum-coated material of transfer method.
Polyvinyl chloride (PVC) aluminizer, except having the barriers such as protection against the tide, choke and the reflection of good light and vivid metallic luster, also has fabulous kink performance, is widely used in the packings such as high-grade chocolate, candy, preserved fruit, cake.Along with the continuous rising to the aesthetic of product external packaging and quality requirement thereof, the requirement of PVC aluminium coating film layer firmness, brightness is further improved.
Current PVC aluminium coating film is that PVC film is directly carried out to AM aluminum metallization in vacuum chamber, produces PVC aluminium coating film.The structure of PVC aluminium coating film is generally that aluminium lamination is attached directly on PVC film, and the subject matter of this PVC aluminium coating film is aluminium lamination poor adhesive force, and brightness is poor, consequently when this PVC aluminium coating film being printed or twists together packing, easily dealuminzation powder, and the low in glossiness of printed patterns is not bright-coloured.
Therefore, how to produce a kind of PVC aluminium coating film, make the aluminium lamination jail that combines with base material PVC film, have and well adhere to adhesion with aluminium molecule; Meanwhile, simplification of flowsheet, reduces production costs, thereby improves productivity effect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of manufacture method of PVC aluminium coating film is provided, make the aluminium lamination of the obtained PVC aluminium coating film jail that combines with base material PVC film, have and well adhere to adhesion with aluminium molecule.
A manufacture method for PVC aluminium coating film is stepped on deposited release agent in carrier film, and aluminium is put into evaporation boat, then unreel, on carrier film surface, carry out vacuum aluminum-coatedly, then bonding agent is coated in carrier film surface, then carry out compound with PVC film, dry, separation, removes carrier film, wherein, on carrier film surface, carry out directly when vacuum aluminum-coated, vacuum is 1 * 10
-2～1.2 * 10
-2pa; In evaporation boat, temperature is 1410～1450 ℃.
Preferably, unreeling speed is 200～350m/min.
Preferably, described release agent is acrylic acid release agent.
Preferably, carrier film comprises biaxial stretching polyester film, two-wayly draws a kind of in secondary polypropylene screen.
Preferably, bonding agent is esters of acrylic acid bonding agent.
Preferably, PVC film and carrier film are carried out compound tense and must be carried out corona pre-treatment.
Compared with prior art, beneficial effect of the present invention:
Vacuum used, temperature and the speed while unreeling when carrier film surface vacuum of the present invention is aluminized, after making aluminum evaporation, aluminium steam is attached to carrier surface comparatively uniformly, good with carrier conjugation, thereby, when carrier and PVC film remove carrier side after compound, the PVC aluminium coating film color and luster of gained is good, quality is better, adhesive force good; Meanwhile, the present invention's release agent used, bonding agent price are comparatively cheap, have reduced production cost, have improved productivity effect.
The specific embodiment
Referring to the specific embodiment, further describe the present invention, to make those skilled in the art can implement according to this with reference to description word, protection domain of the present invention is not limited by embodiments of the present invention.
