Abstract
The invention relates to a preparation method of a seamless holographic film. The preparation process comprises the following steps: applying a transfer coating on a PET film; drying the film with the transfer coating; treating the film with a No.1 group of die pressing rollers, and transferring the holographic patterns of the No.1 group of rollers to the film; then continuously treating with a No.2 group of die pressing rollers, and transferring the holographic patterns of the No.2 group of rollers to the film, wherein the holographic patterns of the No.2 group of rollers just cover the cold oil area of the No.1 group of rollers, and the cold oil area of the No.2 group of rollers shows the holographic patterns of the No.1 group of rollers; and then, treating the film with a group of ironing rollers to obtain a seamless holographic film. According to the preparation method, the seams of the holographic patterns are eliminated, the continuity of the holographic patterns of the PET film is realized, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of preparation method of holographic film, especially one kind are capable of continuous seamless and turn hologram pattern
PET film production method.
Background technology
, in late nineteen eighties the early 1990s incoming China, age nineteen ninety is in all parts of the country for laser embossed holography anti-counterfeiting technology
Up to a hundred of introduction of production line.At the initial stage of introduction, this anti-counterfeiting technology serves certain anti-fake effect really, but complete with laser
The rapid diffusion of breath image making technology, is broken through by fake producer, antiforge laser holographic labeling is almost complete soon in all its bearings
Entirely lose anti-counterfeit capability, and the product that no-plate seam holographic pattern product is molded out than single plate has significantly on antifalse effect
Lifting.Continue through a roller and No. two rollers by scribbling transfer coated PET film, under High Temperature High Pressure effect, will
On radium-shine roller mother matrix, concavo-convex embossment copies in PET film, the two alternate with each other thus assuming one kind continuously holographic radium
Penetrate effect.
Content of the invention
Present invention aim to solving above not enough and providing and a kind of adopt two groups of moulded board rods to eliminate the complete of versions seam
Breath method for manufacturing thin film.
In order to achieve the above object, a kind of preparation method of no-plate seam holographic thin film, it is as follows that its preparation process includes operation：
1）Transfer coatings are coated in PET film, dry rolling；
2）By the rolling thin film of this coating through forging printing plate roller is organized through No. one with certain speed, No. one under a certain pressure
Group forging printing plate roller deep fat area pattern is transferred on thin film, and cold oil region no transfers pattern and assumes version seam；
3）This thin film rotates after certain distance with moulding press, organizes mold pressing roll, No. two group mold pressing roll cold oil regions and through No. two
Number group mold pressing roll cold oil region just replace, under a certain pressure No. two group hologram patterns be transferred on this thin film, by thin film
Hologram pattern is completely covered at gap, and two groups of roller cold oil areas assume the hologram image of one group of roller；
4）This thin film is rotated further by an ironing roller, and hereafter cooled winding is thus obtain seamless holographic film.
Wherein, described transfer coatings are laser-type transfer coatings, and a described group forging printing plate roller exists for diameter
The solid metal roller of 550mm-610mm, cold oil sector width 1-6mm, No. two described group mold pressing roll are diameter 560mm-610mm's
Solid metal roller, than a big 1-4mmmm of group, cold oil sector width is 1-4mm to diameter.
Specific embodiment
Embodiment 1
1）The laser transfer coatings tieing up triumphant chemical industry BH-1001B are coated on Ningbo Shun of 18 μ mould in PET film, 100 DEG C-
Rolling is dried under 130 DEG C -140 DEG C -90 DEG C of thermograde；
2）By rolling thin film through with the speed of 40m/min, through a forging printing plate roller organizing 580mm diameter, deep fat area temperature is
150 DEG C, pressure is 20kg, and a group forging printing plate roller deep fat area pattern is transferred on thin film；
3）This thin film rotates after 60cm with moulding press, through No. two group mold pressing roll of 585mm diameter, No. two group mold pressing roll deep fat areas
Temperature is 155 DEG C, and pressure is 22kg, and No. two group hologram patterns are transferred on this thin film, because of No. two group rollers and a group version
The cold oil region of roller intersects just, thus thin film is covered at the gap of cold oil area no hologram pattern after a roller completely
Lid, two groups of roller cold oil areas assume the hologram image of one group of roller；
4）This thin film is rotated further by an ironing roller, and hereafter cooled winding is thus obtain seamless holographic film.
It is pointed out that an above case for this invention, any company or individual can be carried out based on this
Adjustment, all within the protection domain of this patent of invention.
