Description

Semi-transparent grey plasticising ink for silk screen printing
Technical field
The invention belongs to the technical field of printing-ink, in particular, the present invention relates to semi-transparent grey plasticising ink for a kind of silk screen printing.
Background technology
Ink is the important materials for wrapping material printing, and it comprises main component and ancillary component by printing by pattern, the present stock curing ink of literal table, and they mix equably and form the gluey fluid of a kind of viscosity through repeat-rolling.Printing-ink is by dispersed pulpous state colloids mixing of material such as colorant, low-melting ink vehicle and auxiliary agent and solvents.The binder of solvent type ink consists of solid resin and a large amount of volatile organic solvent.After solid resin is dissolved in solvent, colorant is dispersed in binder, ink is printed to printed medium, the rapid volatile dry conjunctiva of solvent.
For ink, general expectation is used and can on printed medium, be produced aesthetic effect and the permanent printing characteristic keeping that simultaneously shows pleasant.The example of these printing characteristics comprises press quality, as optical density (OD), colourity etc.; And weather resistance, as water tolerance, resistance to fadedness, persistence, acidproof and alkaline-resisting etc.Plastisol ink composite is often known as plastisol ink, because the mode applying is utilized the fluid properties of plastisol before heating, by baking or thermofixation, causes the base resin in plastisol to be solidified into solid.In prior art, most plastisol is in the softening agent being dispersed in based on phthalic ester, also passes through in the composition of its polyvinyl chloride (PVC) RESINS that swelling occurs.Polyvinyl chloride (PVC) RESINS plastisol ink is widely used for silk 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 guaranteeing, under the prerequisite of ink quality, to develop performance identical with PVC plastisol, and the ink with less health and environmental risk and high tack becomes those skilled in the art's R&D direction.
Summary of the invention
In order to solve above-mentioned technical problem of the prior art, the object of the present invention is to provide semi-transparent grey plasticising ink for a kind of silk screen printing.
In order to realize foregoing invention object, the present invention has adopted following technical scheme:
