Description
Technical field
The present invention relates to a kind of bloom pearly-lustre laser papers and preparation method thereof, belong to speciality paper technical field.
Background technique
The continuous rapid advances of human civilization use environmental resource with exhausting, and cause the change of environment, destroy.The mankind make
Plain paper, to set material as raw material, if being not seeking to replace natural paper, trees can be fewer and fewer, and environment also can be into one
Step is destroyed.And the composition of iridescent paper is identical with common white board, i.e., is made of bottom fiber, filler and surface covering three parts,
Common white board can be replaced to use.And there are also the particles for forming pearl effect in iridescent paper surface covering, than common blank
Paper it is more beautiful with it is high-grade.
Currently, radium-shine paper jam has become the first choice of medium and high classes packaging, it is according to anti-fake requirement, by special type plate-making, meter
The one of the multinomial new and high technology combination such as the photoetching of calculation machine, precise electrotyping, laser holographic molding, fine chemistry industry and high-precision removing
Kind antifalse, environment-friendly package material.
Laser paper is a kind of the information such as holographic grating pattern or text to be loaded into paper or film by way of molding
On, and pass through a kind of special paper of metal or medium to show grating information.It is radium-shine under natural light or light-illuminating
Paper forms the laser effect as seven glory of rainbow by the reflection of different angle, Different Rule to light.
With the improvement of living standards, people increasingly pursue beautiful and stylish and individual character, simple pearly-lustre paper jam or radium
Penetrate the esthetic requirement that paper jam is no longer satisfied people as wrapping paper.Simultaneously there is the paper of pearly-lustre and laser effect can be promoted
The appearance of wrapping paper is beautified and class, meets the aesthetic requirement of present people.But at present radium-shine paper jam produced in industry,
The paper of pearly-lustre paper jam type is that a point shape produces, independent simple, only individual radium-shine type or the direct coating class of pearlescent pigment
The product of two kinds of type independent effects.Temporarily a kind of product is to integrate radium-shine and pearl effect not yet, i.e., on a sheet of paper
Existing radium-shine distinctive diffracting effect, while having the distinctive change spar effect of pearlescent pigment again.
Summary of the invention
The technical problems to be solved by the invention: for radium-shine paper jam produced in current industry, pearly-lustre paper jam type
Paper be that a point shape produces, independent simple, the only individual independent effect of two kinds of radium-shine type or the direct painting type of pearlescent pigment
The problem of product of fruit, provides a kind of bloom pearly-lustre laser paper and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of bloom pearly-lustre laser paper successively includes surface layer, radium-shine layer, dielectric layer, bloom pearl layer, body paper from top to bottom.
A kind of preparation method of bloom pearly-lustre laser paper, specific steps are as follows:
(1) BOPET film is placed on coating machine and is coated with transfer glue, obtain radium-shine basement membrane；
(2) radium-shine basement membrane is molded and is printed, form the radium-shine coated film for having information；
(3) it is surface-treated in radium-shine coated film, and medium is deposited, obtain laser film；
(4) bloom pearly coating is prepared；
(5) pearly coating is coated on body paper surface, obtains bloom iridescent paper；
(6) laser film is bonded with bloom iridescent paper upper surface, BOPET film is removed after dry solidification, and the table after removing
Face carries out face and applies to form surface layer, dry bloom pearly-lustre laser paper.
For step (1) BOPET film with a thickness of 15~24 μm, the transfer glue is UV gloss oil, coating weight is 2.0~
3.5g/m2。
Step (2) the molding printing process is 120~135 DEG C, winding tension are 4~6kg, machine speed is 30~40m/
Min, molding pressure are 0.3~0.5MPa lower die coining brush.
Step (3) surface treatment is 12~15A of electric current, machine 30~40m/min of speed, the electricity of 4~6kg of retractable volume tension
Dizzy processing.
Step (3) the vapor deposition medium be it is vacuum aluminum-coated, coating film thickness be 1~10 μm.
Weight of material part is 30~40 parts of sheet micas in step (4) the bloom pearly coating, and 2~3 parts silane coupled
Agent, 1~2 part of rare-earth coupling agent, 200~300 parts of dehydrated alcohols, 500~600 parts of acrylic emulsions, 0.2~0.3 part of defoaming agent,
0.2~0.3 part of levelling agent, 5~6 parts of paraffin, 150~180 parts of deionized waters.
Step (5) the pearly coating coating weight is 8~10g/m2。
120~150 DEG C of step (6) dry solidification, the investment precoat be acrylic resin, coating weight be 2.0~
3.5g/m2, drying temperature is 100~120 DEG C.
The present invention is compared with other methods, and advantageous effects are:
(1) present invention utilizes UV gloss oil before the drying, has extremely strong plasticity, and in UV gloss oil rapid draing, again
Thoroughly the essential information on laser film can be lived by dry solidification, using the concave-convex graph text information on laser film as most basic mould
Tool, is applied on BOPET film surface by UV gloss oil, and after carrying out die casting, BOPET film graph text information just will shape
At will shape after then only needing to wait UV gloss oil dry solidification with bumps laser graphic information consistent on laser film
At laser graphic, and realize certain bloom laser effect；
(2) present invention has abundant by the pearly coating of preparation bloom using the special 4f electron structure of rare earth element
Visible region spectral line is coated on sheet mica surface as chromophoric group, and rare earth element enters sheet mica as dopant
Crystal phase structure or lattice parameter can be changed in lattice surface and sheet mica is made to generate special colour, rare earth ion polarizability is high,
The refractive index that crystal can be improved into sheet mica crystal enhances the reflecting effect of light, while the high photosphere on its surface and steaming
After plating medium-tight fitting, rare earth element can also enhance the bloom effect of coating medium, be made while having pearly-lustre and radium-shine effect
The paper of fruit promotes appearance beautification and the class of wrapping paper, meets the aesthetic requirement of people.
