Diluent added by scene is possible to just use unboiled water, and the microorganism in unboiled water is a lot.Levelling agent is used to improve ink be printed onto and holds
Play moistening base material when on print thing, improve ink and iridescence occurs, the even phenomenon showing money or valuables one carries unintentionally of irregular colour occurs.The acting on of diluent
Improve print speed printing speed, drying property, the stability of color in printing, viscosity controls.
3rd, the resistance to water of plastics aquosity intaglio printing ink of the present invention, resistance to acids and bases, solvent resistance, rub resistance is more similar than other
Ink improves significantly, and can apply to high-quality printing.Plastics aquosity intaglio printing ink of the present invention can be applied to multiple products
Above, above the product of such as PE, PET, POPP and PVC.
4th, traditional aquosity intaglio printing ink great majority be pH value below 8.0, and think that pH value is less than 8.0 and is conducive to improving
Print speed printing speed, but the problem of blocking printed panel often occurs in actual intaglio process.Iff by water above market
Property gravure ink pH value be adjusted to more than 8.0 and occur that stability is poor, the problem of gravure effect difference.For solving this problem, I
By improving to binder, using amino resins and water-based aliphaic polyurethane resin as raw material, by dispersant
8.5-9.5 is adjusted to its pH value, it has surprisingly been found that not only the problem blocking printed panel in this aquosity intaglio printing ink,
And there is good stability, i.e. the big feature of the three of the transitivity of ink, wettability and solubility.In actual printing process
In, the features such as production efficiency is high, bright-colored and Well-recovered.
