The following technical means are adopted: the non-benzene imaging layer for the laser hot stamping foil comprises toner and is characterized by comprising the following components in part by weight: 1 to 3 parts of ethylene glycol, 15 to 30 parts of butanone, 15 to 30 parts of butyl ester, 1 to 5 parts of nitrocotton, 40 to 60 parts of acrylic resin, 0.1 to 0.4 parts of leveling agent and 0.01 to 0.05 parts of antifoaming agent.

Description

No benzene imaging layer and preparation method that a kind of laser electrochemical aluminum is used

Technical field

The present invention relates to dyestuff, coating and tamanori field, be specifically related to a kind of laser electrochemical aluminum.

Background technology

The laser electrochemical aluminum stamping systems is to form some tiny indentures through mold pressing; Through refraction, the diffraction of indenture to light; Produce seven color effects, and it is transferred to surfaces such as enamelled paper, yew paper, printing ink paper, timber, leather, silk, form novel packing thermoprint base material; Than general electrochemical aluminium stronger anti-counterfeiting performance is arranged, have the stronger stereoscopic sensation and the sense of reality.

The coating of imaging layer is the key that mold pressing obtains exquisite laser effect; At present, even still there is problem of solvent residue in the figure layer that contains toluene at last through bake drying; Can make printing supplementary material organic volatile content overproof, and use toluene also can cause certain harm environment.

But use a large amount of toluene as solvent again in the imaging layer coating of prior art; Guarantee imaging dissolving resin property and stability in the coating, if general imaging layer resin does not use toluene, coating quality is very unstable; There are problems such as white point, irregular colour be even to exist easily; In the operation mold pressing of back, sticking version and trachoma problem can appear frequently particularly, and can't stably manufactured.

Simultaneously, original imaging layer coating need be coated with the requirement that could satisfy color through repeatedly repeating when the dark electrochemical aluminium of preparation, reduced production efficiency, increases production cost.

So the laser electrochemical aluminum imaging layer should be avoided adding toluene and make solvent, can guarantee imaging dissolving resin property and stability in the coating simultaneously again.

Summary of the invention

For solve electrochemical aluminium imaging layer that prior art exists use toluene do the solvent organic substance residues more, do not use toluene exist again can't stably manufactured problem; The present invention aims to provide a kind of toluene that do not add as solvent, and do not exist coating quality unstable, have that white point, irregular colour are even, occur problem such as sticking version in the operation mold pressing of back.

For achieving the above object, the present invention adopts following technique means: the no benzene imaging layer that this laser electrochemical aluminum is used is characterized in that; Concrete prescription is counted by weight: ethylene glycol ethyl ether 1-3 part, butanone 15-30 part, butyl ester 15-30 part; Nitro-cotton 1-5 part; Vinyl resin 40-60 part, flow agent 0.1-0.4 part, skimmer 0.01-0.05 part and toner.

The no benzene imaging layer that described a kind of laser electrochemical aluminum is used is characterized in that, concrete prescription is counted by weight: ethylene glycol ethyl ether 2-3 part; Butanone 20-25 part; Butyl ester 20-25 part, nitro-cotton 2-4 part, vinyl resin 50-55 part; Flow agent 0.2-0.3 part, skimmer 0.02-0.04 part and toner.

The preparation method of the no benzene imaging layer that this laser electrochemical aluminum is used is characterized in that, may further comprise the steps:

A, stir adding in the container by the load weighted butanone of formula rate, butyl ester, ethylene glycol ethyl ether, stirring velocity is 300-450r/min;

1/8 nitrocellulose solution, the vinyl resin of c, adding 30% in the mixed solution that step b obtains stirred 10-30 minute together, and stirring velocity is 300-450r/min;

D, in the mixed solution that steps d obtains, add flow agent, skimmer respectively and stirred 5-20 minute, stirring velocity is 300-450r/min, gets final product after the filtration.

Said flow agent is ROHM, Uvex, YSR 3286, a kind of in the PSI.

Said skimmer is fluorine-containing modified organic silicon, a kind of in tributyl phosphate, n-Octanol, alcohol, the liquor.

With the no benzene imaging layer coating for preparing at ambient moisture below 80%, through anilox roll with 5-6g/m 2Glue spread be coated on the release layer, through behind other preparation technologies, have a laser electrochemical aluminum that does not contain toluene of different colours.

The invention has the beneficial effects as follows:

A, the invention provides a kind of toluene that do not add as solvent, and do not exist coating quality unstable, have that white point, irregular colour are even, occur the laser electrochemical aluminum imaging layer material of problems such as sticking version in the operation mold pressing of back.

B, the present invention solve the electrochemical aluminium imaging layer that has had technological existence now use toluene do the solvent organic substance residues more, do not use toluene exist again can't stably manufactured problem.

The no toluene imaging layer material of C, the present invention's preparation has characteristics such as rate of drying is fast, good film-forming property, good leveling property, can be fit to make versicolor electrochemical aluminum simultaneously.

D, the laser electrochemical aluminum product mold pressing brightness of using the present invention to produce be high, be difficult for fading, cutting property is good, and it is wide to fit the scope of scalding.

The imaging layer material of E, the present invention's preparation is prone to store, and can under 0-35 ℃ environment, store more than one month.
