Description

A kind of pearly-lustre holographic false proof paper and its preparation technology
Technical field
The invention belongs to pack and decoration material field, it is related to a kind of pearly-lustre holographic false proof paper and its preparation technology.
Background technology
The packaging material of pearl effect plays an important role always in packaging field, in recent years radium-shine colorful bag Package material also increasingly receives an acclaim, and laser effect is in addition to itself can bring visual effect to consumer, moreover it is possible to enhancing production The anti-counterfeiting performance of product.With the improvement of living standards, requirement of the consumer to packaging material also more and more higher, simple iridescent paper Or laser paper can not meet the esthetic requirement of consumer as wrapping paper.There is the paper of pearly-lustre and laser effect simultaneously The attractive in appearance and class of wrapping paper can be lifted, meets the aesthetic requirement of present people.In the market temporarily also without a kind of product To integrate radium-shine with pearl effect, i.e. existing radium-shine distinctive diffracting effect on a sheet of paper, while there is pearlescent pigment again Distinctive change spar effect.
Patent is had at present discloses obtained pearly-lustre laser paper, patent of invention(CN 105525536 A )Radium-shine pearly-lustre paperboard and its Preparation method, the preparation method of the invention is that pearl essence and glue are proportionally mixed to get into compo, and compound is applied Cloth is then combined with laser film, peeled off on paper.The patent is not aluminized or medium, is aluminized on laser film if do not increased Or plating medium effect, if being directly combined after molding with glue, that laser effect will disappear.Patent of invention(CN 104960353 A )A kind of pearly-lustre laser paper and its preparation technology, preparation technology is:In the Bopp basement membranes with radium-shine layer Upper coating pearlescent pigment layer, medium is plated after carrying out surface tension reinforcement processing to pearly-lustre transfer layer in the above again, is being situated between afterwards One layer of transfer adhesive water layer is coated with matter layer;Former recto is combined with transfer adhesive water layer after the back of the body is applied again, and Bopp basement membranes are peeled off After obtain the invention product.The technique has plated one layer of medium on pearl layer, and pearl layer is protected using the transparency of medium. But, the invention is directly coated with pearl layer on laser information layer, does not have dielectric layer between radium-shine layer and pearl layer.Utility model Patent(CN 205188713 U)A kind of colorful pearly-lustre laser packing paper, is also that pearl layer is directly coated with laser information layer, There is no dielectric layer between radium-shine layer and pearl layer.The purpose of plating medium is pearly-lustre laser effect is kept transparent performance, can be obtained To more preferable pearly-lustre laser effect, while making the adhesion property of pearly-lustre transfer layer more preferable.
The content of the invention
Present invention mainly solves deficiency present in existing product, there is provided a kind of pearl effect is good, laser pattern is clear, peace The paper that loopful is protected, while providing a kind of preparation technology of pearly-lustre holographic false proof paper.
The present invention technical solution be:A kind of pearly-lustre holographic false proof paper, includes radium-shine layer, transparent successively from top to bottom Dielectric layer, pearl layer, glue layer, body paper.
The transparent dielectric layer is zinc sulphide transparent dielectric layer.
The pearl layer is not limited to full version, special edition or patterned pearl layer.
The radium-shine layer is not limited to the radium-shine layer of hollow out or the radium-shine layer of full version.
The preparation technology of above-mentioned pearly-lustre holographic false proof paper, including following process:
1】Transferable coating and heating, drying are coated with transfer basement membrane, moldable coating is obtained:, will be transferable on coating machine Coating is uniformly applied on PET basement membranes by anilox roll, and heating, drying obtains moldable coating;The cable roll can be The steel of 200~300 lines or ceramic cable roll;Coating speed is 100-150m/min speeds, and hot drying temperature is 80-150 DEG C; The PET film is reusable;Its thickness is 12 μm~18 μm;
2】Molding laser information, obtains laser information layer on moldable coating:The laser information layer is by vertical with three-dimensional The holographic Ni plate mould pressure of body pattern is formed, and moulding press molding speed is 40-60m/min, and molding temperature is 130-180 DEG C, molding Radium-shine thickness degree be 1.0 μm -1.5 μm;
3】The spraying plating zinc sulphide on laser information layer, obtains dielectric layer:By molybdenum boat by the zinc sulphide of high-purity on aluminum-spraying machine Spraying plating obtains dielectric layer on laser information layer;The % of the zinc sulphide purity >=99.0, the thickness of dielectric layers of spraying plating is in 0.15 μ M-0.25 μm, the vacuum of aluminum-spraying machine is 2 × 10-2 - 7×10 -2Pa;
4】Pearly coating is coated with dielectric layer by cable roll, pearl layer is obtained:The pearl essence of certain mass number is weighed, It is distributed under room temperature condition with mixer in aqueous polyurethane coating, stirring to pearl essence is completely dispersed uniformly.The pearl essence Particle diameter be 10 μm -80 μm, pearl essence weight/mass percentage composition is 10%-30%, preferably 15%-25%, and the pearl essence can be with It is white, gold, black, blueness etc.;
5】On compounding machine, the pearl layer and body paper on transfer basement membrane are combined with each other with glue, it is then solid through oven for drying Change;The glue requires it is transparent after drying, and obvious cover is not produced on the color on paper surface influences;It can use Commercially available specific complex glue;Paper can be 50~300g/m2Paper, paper be combined face color can be white, also can be in paper Open surface and be pre-coated with dyed layer, color can be the progressive coloured of various forms that are monochromatic or being produced by monochrome;
6】Transfer basement membrane is peeled off.
It is an advantage of the invention that:(1)The present invention paper good visual effect, it appear that be not merely radium-shine color Make oneself too remarkable, nor be only the gentle soft of pearly-lustre color and luster, but the combination of both visual effects.This combination is not only Conflict or contrast will not be constituted, a kind of deep graceful sense is given people on the contrary.Paper of the present invention has radium-shine and pearly-lustre antifalsification concurrently, Its antifalse effect is stronger, can be widely used in a variety of expensive goods packagings such as cosmetics, tobacco and wine, medicine, clothes.
(2)Due to aperture is distributed with radium-shine layer, laser effect is produced using the diffraction or reflection of light, pearlescent pigment contains There is particle, if being directly coated with pearl layer on radium-shine layer, pearlescent pigment can block aperture, weaken laser effect, therefore, this Shen Please transparent medium is placed between pearl layer and radium-shine layer, laser information can be protected not disturbed by pearl layer well, made Laser information is clearly presented;The presence of transparent dielectric layer also serves protective effect to pearl layer, moreover it is possible to make the pearly-lustre of pearl layer More preferably, pearl layer will not weaken, absorb or change incident ray to effect because of the covering of radium-shine diffracting layer, so that the color of pearly-lustre Pool can show that anti-counterfeiting performance is stronger completely.Pearl layer forms the background color of a floor height brightness below radium-shine layer, seemingly, to be upper The radium-shine color in face adds saturation degree, enriches visual experience.Product laser information complete display, the level finally obtained is rich Rich, pearl effect is preferable.Glue layer does not interfere with the pearl effect of pearl layer below pearl layer, yet.
(3)Present invention process is simple, and the PET film after stripping can be reused several times, cost-effective, is improving production efficiency While, also act the effect of energy-conserving and environment-protective;Aqueous polyurethane coating environmental pollution is small.
