A kind of PP glue for local aluminum plating process heat transfer film
Technical field
The invention belongs to thermal transfer field, especially relate to a kind of PP for local aluminum plating process heat transfer film
Glue.
Background technology
Thermal transfer is a newer typography, and it is by printing carrier (usually PET biaxial stretching polyester
Thin film), release layer, ink layer, gum layer composition, then will be from through certain temperature, pressure by thermoprinting machine
Type layer, ink layer strip down from printing carrier, are securely attached to by ink by the bonding effect of PUR
It is transferred on base material.This technology is widely used in the row such as article of everyday use, cosmetics, engine oil drum, building dalle
Industry.
Local aluminum plating process heat transfer film is that the method using vacuum evaporation obtains metal effect on the surface of transfer film,
Then by washing step, unwanted aluminium lamination is washed, obtain the heat transfer film of a kind of localized metallic, such as local
Minute surface gold effect, specular local surface silver-like effect.This heat transfer film through thermoprinting machine at certain temperature and pressure
Lower metal effect is transferred to printed substrate surface, make printed substrate have metal effect true to nature and texture, permissible
It is greatly improved the decoration functions of transfer product, improves the class of product.
Local aluminizing heat transfer film consisting of, first coating function layer (i.e. release layer) on printing carrier, then
Printed patterns Information Level (i.e. ink layer), (the i.e. thermosetting of ink protective layer, generally bi-component of ink colorant layer
Type resin bed), clean ink layer (during washing, the position that need not aluminium lamination being washed off), be then passed through aluminizing, washing,
The hot melt glue that finally coating and transfer substrate match forms.
Local aluminum plating process heat transfer film produces at stationery such as Neutral ball-point for ball-point pen, penholder, marking pen, white board marker, lead boxes
It is widely used on product.And Neutral ball-point for ball-point pen, marking pen, white board marker are typically all PP material, existing for PP
The gum of the aluminum plating process heat transfer film of material, will be made up of twice glue, and first pass to be coated with together aluminum and ink
The combinative protective layer of dyed layer, then repastes one PP glue so that it is be combined with PP base material, technics comparing
Trouble, and owing to protective layer and PP glue are due to its resin compatible sex chromosome mosaicism, there is the pen after heat transfer film and transfer
Bar can lose the problem of adhesive force after placing a period of time, causes product failure.

Compared with prior art, the invention have the advantages that
1) PP material i.e. polypropylene, is a kind of thermoplastic resin being polymerized by propylene monomer, due to PP material
Expecting that its surface crystallization is high, polarity is low and surface can be low, it is more difficult to bonding, attachment.The maleic acid that this patent selects changes
Property chloridized polyolefin or acrylic acid modified chlorinated polyolefin resin, make it not only to PP by the polarity improving resin
Material has fabulous cementability, and adds EVA resin, itself and modified chlorinated polyolefin resin in the present invention
Produce cooperative effect so that it is ink colorant layer, i.e. bi-component protective layer are also had stronger adhesive force.And this
The epoxy modified acrylic resin of bright selection be a class to metal, especially aluminium is had good bonding force.
PP base material is not only had by the glue that therefore present invention is prepared by selecting three or more functional resin
Well adhesive force, and aluminium lamination and ink colorant layer are had the strongest adhesion, can be used for aluminum plating process thermal transfer
The gum of film, replaces PP material aluminum plating process heat transfer film need to first be coated with a protective layer and repastes glue layer (please from instead
Answer mechanism to set out, in conjunction with the raw material used, be described further), simplify technique, cost-effective;
2) the glue that prepared by the present invention select toluene, methyl ethyl ketone, ethyl acetate mixed solvent as solvent,
The boiling point of its solvent is different with rate of volatilization, is beneficial to solvent volatilization during coating, makes glue dries good, levelability
Good (ibid, being further explained explanation);
3) the glue adhesive force that prepared by the present invention is excellent, owing between the resin that the present invention selects, the compatibility is good, and system
Standby glue good stability, the heat transfer film stable performance after gluing, long shelf-life, make the heat transfer film shelf-life surpass
Spend 1 year;And conventional silver lustre process heat transfer film glue two-layer the to be coated with diverse glue of character, exist
Workpiece after the problem of interlayer result, heat transfer film or transfer lost efficacy through there will be adhesive force after a period of time
Problem (ibid, being further explained explanation);
4) present invention prepares simply, operates safety, only needs simple container, it is not necessary to heating, through mechanical agitation
?.
