Description
Technical field
The present invention relates to plastic printing field more particularly to a kind of water-based plastic inner printing ink and water-based plastic table stamp-pad ink
Ink.
Background technique
Plastic printing includes Biao Yin and inner print, and wherein table print, which is strained the meaning of the word, refers to for ink being printed on film surface, inner
It prints and refers to printing ink on thin film, then the coating adhesive in the film layer that the film and ink are formed, later
Another layer film is fitted in described adhesive again, so that ink film layer clamping is between double-layer films.
Existing water-based plastic table printing ink is usually aqueous acrylamide acid system, although the water-based plastic table printing ink is available
Printed in Plastic film surface, but the film type that can be printed is single, for example, the water-based plastic table printing ink be printed in it is highly dense
Degree, on low-density polyethylene film when adhesive force it is preferable, but adhesive force is poor when being printed on polypropylene film, in other words,
Existing water-based plastic table printing ink can not be general on the films such as polyethylene, polypropylene, PET, PVC, aluminium foil.Select solubility
Poor aqueous acrylic emulsion is come when preparing water-based plastic table printing ink, and water resistance is preferably after film forming but to will appear stifled version existing
As increasing the workload of worker, and product printing effect difference causes product unqualified.Select the preferable aqueous acrylamide of solubility
Will appear when preparing water-based plastic table printing ink after film forming, the finished product printed is not resistant to water, meets water rubbing to fade yogurt liquid
The problem of.When the selection preferable acrylic emulsion of solubility prepares water-based plastic table stamp-pad ink with the poor lotion interworking of solubility
Mo Shi, product is not resistant to water after still will appear printing film forming, slightly rubs the problem of fading after meeting water.
Existing water-based plastic inner printing ink is usually aqueous polyurethane system, this water-based plastic inner printing ink to PET,
The adhesive force of nylon film is good, relatively poor to the adhesive force of polypropylene printing film, and poor water resistance.When water resistance is too poor
It will appear when printing and sting color phenomenon (ink that the ink printed below when polychrome printing prints front dissolves, and occurs stinging color existing

The water of middle use is deionized water.
Generally speaking, water-based plastic inner printing ink of the invention use and be printed in directly as inner-printing ink polypropylene,
When on the films such as PET, for existing water-based plastic inner printing ink, ink the low problem of film surface adhesive force with
And sting color problem and significantly improve, it is also had no obvious dissolution now in dry-lamination process using aqueous compound adhesive compound tense
As being not in white point.
Water-based plastic inner printing ink provided by the invention is used as table printing ink in use, by it after mixing with aqueous varnish
It is the adhesive force that shows, glossiness, rub resistance, wear-resisting resistance to when being printed on the films such as polyethylene, polypropylene, PET, PVC
The table printing ink of scraping property, water resistance and printing adaptability all than single acrylic emulsion system is more excellent.
Specifically, water-based plastic inner printing ink of the invention and water-based plastic table printing ink use deionized water when in use
Adjusting printing viscosity can use on the machine.
Those skilled in the art understand that most of plastic printing ink of existing commercial type contains 5%
Above ethyl alcohol, this printing ink easily detonation, degree of danger is very high, and water-based plastic inner printing ink of the invention with it is aqueous
Plastic table printing ink is entirely free of alcohols material, not only environmentally friendly, but also is not easy detonation, and degree of danger substantially reduces.
Since moistening flatting agent, defoaming agent, fungusproof anti-corrosion agent and pH adjusting agent that the present invention uses are plastics print
