Description

Mute black environmental protection plasticising ink
Technical field
The invention belongs to the technical field of printing-ink, in particular, the present invention relates to a kind of mute black environmental protection plasticising ink and preparation method thereof.
Background technology
Ink is the important materials for wrapping material printing, and pattern, the present stock curing ink of literal table are comprised main component and ancillary component by printing by it, and they mix equably and form the gluey fluid of a kind of viscosity through repeat-rolling.Printing-ink is by the pulpous state colloid of colorant, low-melting ink vehicle and the homogenize material such as auxiliary agent and solvent dispersing and mixing.The binder of solvent type ink is made up of solid resin and a large amount of volatile organic solvent.Solid resin is dissolved in after in solvent, is dispersed in by colorant in binder, and ink is printed to printed medium, the rapid volatile dry conjunctiva of solvent.
For ink, general expectation uses the aesthetic effect and the permanent printing characteristic kept that can produce on printed medium and show pleasant simultaneously.The example of these printing characteristics comprises press quality, as optical density (OD), colourity etc.; And weather resistance, as water tolerance, fade resistance, persistence, acidproof and alkaline-resisting etc.Plastisol ink composite is often referred to as plastisol ink, because the mode applied utilizes plastisol fluid properties before heating, causes the base resin in plastisol to be solidified into solid by baking or thermofixation.In prior art, most plastisol is dispersed in the softening agent based on phthalic ester and is occurred in the composition of swelling polyvinyl chloride (PVC) RESINS by it.Polyvinyl chloride (PVC) RESINS plastisol ink is widely used for screen printing operation.But due to the consideration of environment, health and safety, the use of these ink is subject to strict restriction just day by day.Therefore, under the prerequisite ensureing ink quality, develop performance identical with PVC plastisol, but the ink with less health and environmental risk becomes the R&D direction of those skilled in the art.
