Description
Technical field
The present invention relates to a kind of water-based ink and preparation method thereof, belong to ink area.
Background technology
Its composition of water-based ink particularly printed form ink mainly includes：Binder (polymerizing prepolymer), pigment, water and
Other auxiliary agents.Its feature is to employ water-base resin as link stuff, is broadly divided into two types：Water dilution type and moisture dissipate
Type.The resinous type that the former can use has a many kinds, for example, malein acid ester resin, lac, maleic acid resin Modified Shell-lac for Cuprous Surface Anticorrosion,
Urethane, water soluble acrylic resin and water-compatible amino resin etc..The link stuff of water-dispersion type is in water by the list of emulsification
Body polymerization gained, it is two-phase system, and wherein oil phase is disperseed with graininess in water phase, though it can not be dissolved in water, can
It is diluted with water, so it is also assumed that being oil-in-water emulsion type.
Last century Mo, Japanese, South Korea and Southeast Asia etc. have just eliminated countries and regions toluene class printing ink.The U.S.
Off-set oil inkization is just advocated in the eighties in last century, and forbids using solvent-based ink printing plastics in its country.
Printed using water-based ink, it need not use solvent first, only use clear water.Have it is a kind of wrong think,
Addition solvent is The more the better in ink, and such cost is lower.Actually this is not so, the solvent added, was printed entirely
Added in journey.This is because the volatilization of solvent causes ink viscosity to change and add.Print speed printing speed is faster, required allotment it is dilute
The volatility for releasing agent will be faster, and the number for adding solvent is more.This is equal to be constantly increasing printing cost.With ink row
From the point of view of the standard of industry, the colour saturation of ink is high, and viscosity is low to be only ink.Diluent is added in ink, is only used as reducing ink
Viscosity.It is set suitably to print, such as excessive addition, the colour saturation of ink can reduce.The component of binder reduces at the same time, so
Change can not print good product.So water-based ink only adds pure water, and it is disposably to add (before print).In printing process, it
The change of color will not be caused because of the change of viscosity, more will not be as ink, when needing to add diluent in way because printing
Caused waste product, thus substantially increases the qualification rate of printing.The cost of solvent is saved, reduces the appearance of waste product.
This is one of aqueous ink used for plastic cost advantage.
The preparation process of ink generally includes：Packed after dispensing, pre-dispersed, grinding, auxiliary agent adjustment, high speed dispersion, filtering
These links.After rudimentary ink can also disperse only by high-speed stirred or by ball mill, still, generally
Advanced ink such as intaglio plate, flexographic ink generally require by sand mill be ground it is pre-dispersed after carry out high-speed stirred again, this
Ink prepared by sample can be adapted to the requirement of printing equipment.The preparation of water-based ink is also required to carry out the pre-dispersed of sand mill,
In dispensing before pre-dispersed, generally require to add a certain amount of resin, be so conducive to the scattered of mill base, however, carrying out multistage
Easily there is the phenomenon being demulsified in resin after grinding, causes last molding ink the phenomenon being layered easily occur, seriously affects oil
The quality of ink.Someone is also contemplated for being added without resin in the grinding stage, and the ink mill base being prepared disperses inequality, causes printing
Quality decline.
Traditional ink prepares and often uses single resin, is all used in grinding pre-dispersed stage and high speed emulsifying stage
Same resin, such ink can only often embody advantage in a certain respect, and still, single resin ink is often difficult to meet more
The demand of kind technique and function.
The content of the invention
