Abstract

The said holographic duplication techn is that by means of ultraviolet solidifying process, relief-type hologram is duplicated on the surface of glass, plastics, leather fabric and other base material. Being simple and low-costed, the said process is suitable for industrialized production.

Description

Ultraviolet-solidified hologram duplicating technology

The invention relates to a kind of hologram duplicating technology, particularly a kind of ultraviolet-solidified hologram duplicating technology, specifically, the present invention be adopt the ultraviolet light polymerization method with the relief type hologram replication at substrate surfaces such as glass, plastics, leather, fabrics, make these substrates have splendid color or space pattern.

In the prior art, hologram duplicating technology has many, mainly contains following several:

1. secondary writing-method: as thing, on new recording materials, use the laser copying hologram with the reproduction picture of main hologram.

2. copy method: utilize vacuum absorption device, the emulsion layer of hologram and holofilm is fitted tightly, duplicate with the incoherent light exposure.

3. CGH duplicates: the hologram that utilizes computing machine to produce, duplicate on the photograph final reaction system.

Above-mentioned three kinds of methods mainly are used in valuable ornament (as the laser jewel) or have on the holographic copy of article (as anti-false trademark) etc. of specific (special) requirements, and its cost is very high, complex process, and usable range is restricted, and is unsuitable for industrial-scale production especially.

4. mechanography (being called hot moulding holographic copy art again): at first on the holographic light-sensitive recording materials, make a width of cloth embossing hologram (being called master), then the hologram transfer replication on the master is become celature hologram (calling grandmother's version) by electrotyping forming, become some pieces of celature holograms (being called mother's version) by grandmother's version through the electrotyping forming transfer replication again, then mother's version is placed on the special hot press or injection machine, so just can be to thermoplastic resin films such as PVC or PET with the hologram image transfer replication.

Mechanography only is applicable to thermoplastic resin films such as PVC or PET, and needs this resin molding is heated to its softening point, thereby equipment complexity, the technology of duplicating are loaded down with trivial details, replicative cycle is long (about 24 hours); According to the needs of duplication process, the material of described mother's version must be hard sheet metal (as the Ni plate), so the cost of reproduction technology is higher.

The invention provides a kind of applied widely and simple ultraviolet-solidified hologram duplicating technology of technology.

Above-mentioned reproduction technology is implemented as follows:

1. raw material, equipment are prepared: be ready to substrate, UV-cured resin glue, mother matrix, glue spreader, laminating machine, ultraviolet light baking oven etc.;

2. utilize glue spreader that substrate surface is coated with last layer UV-cured resin glue;

3. on the UV-cured resin glue-line of substrate, cover mother matrix by laminating machine;

4. be coated with the substrate of UV-cured resin glue and band mother matrix by the baking of ultraviolet light baking oven, this resin glue is solidified;

5. throw off mother matrix, on the surface of UV-cured resin glue-line, plate Al film or alloy film.

Described substrate can comprise glass, plastics, leather or fabric; UV-cured resin glue is commercially available single component or bi-component resin glue; Mother matrix is metal mother or molded thermoplastics's resin molding, and the space of a whole page or face have concavo-convex embossment; Glue spreader comprises that hopper, the transmission of being with scraper are rolled, travelling belt; Laminating machine comprise transmit roll, nip drum, tightly roll, mother matrix rolls; The ultraviolet light baking oven comprises ultraviolet source, transmits and roll.

The present invention can obtain more detailed description by following embodiment.

Description of drawings: Fig. 1 is the coating technique synoptic diagram; Fig. 2 is the coating technique synoptic diagram; Fig. 3 is the ultraviolet light polymerization process schematic representation.

With reference to described accompanying drawing, choosing glass sheet is substrate, and UV-cured resin glue 16 is placed the hopper 12 of band scraper, by the transmission on the glue spreader 11 roll 13 and travelling belt 14 glass sheet 15 surfaces are coated with the last layer resin glue.Choosing molded thermoplastics's resin molding is mother matrix, and this mother matrix surface has concavo-convex embossment, this film is entangled in mother matrix rolls on 22, the mother matrix film by the nip drum on the laminating machine 21 23, tightly roll 24, transmit and roll 25 and be coated over and scribble the on glass of resin glue.The glass sheet that will be coated with resin glue and band mother matrix film then places the transmission of ultraviolet light baking oven 31 to roll on 32, and selecting low pressure mercury lamp 33 is ultraviolet source, and this moment, resin glue solidified, and it is 10～300mJ/cm that this resin glue solidifies required sensitization energy ²Throw off the mother matrix film at last, plate the Al film on the resin glue-line, the glass that obtains thus is cladding glass, and this cladding glass has laser effect, so be referred to as " radium-shine cladding glass ".

Compared with prior art, ultraviolet-solidified hologram duplicating technology of the present invention need not firing equipment, does not need very big pressure during overlay film, and can adopt mantle is mother matrix, thereby work simplification, production cost reduce, and is specially adapted to suitability for industrialized production.
