Description
Technical field
The invention belongs to water-based ink technical fields, and in particular to a kind of anti-skinning auxiliary agent and its system for water-based ink
Preparation Method and application.
Background technique
Water-based ink is the Main Trends of The Development of the following ink industry, the advantage is that the bulk solvent of water-based ink is
Water, it is few without using volatility VOC in solvent, use in production, it is non-hazardous to environment, it is a kind of environmentally protective novel printing
Material is the Main Trends of The Development of the following ink industry.
But present inventor during inventive technique scheme, has found above-mentioned skill in realizing the embodiment of the present application
Art at least has the following technical problems:
Existing water-based ink is in storage and in use, due to factors such as normal temperature oxidation, infiltration, volatilization, evaporations, aqueous oil
Ink superficial layer contacted with air, caused the polymerization of ink system so that water-based ink superficial layer formed it is solidifying
Glue — that is, the skinning for being commonly called as printing ink.
Due to being difficult to redissolve after skinning, when printing printing ink concentration increases to certain value, surface will be by one layer of molecule
It is covered, even if at this moment using the concentration for adding solvent or grease to reduce ink, on the surface of skinning (gel) also not
More molecules may be accommodated again, are thus caused the dirty version of printing plate of printing machine, are not only reduced printing efficiency, be also easy to generate
Defect ware is printed, needs to shut down cleaning.In this way, not only making troubles to print production, but also cause the very big wave of ink materials
Take.It is estimated that the waste of the ink as caused by water-based ink skinning accounts for 1 ‰~the 1% of total ink.This tangible consumption is given
Packaging and Printing Enterprises increase heavy financial burden, are unfavorable for controlling production cost.
Summary of the invention
In order to overcome the shortcomings of that in press ink is easy skinning to existing water-based ink, the embodiment of the present application provides one
Kind is used for the anti-skinning auxiliary agent of water-based ink, which can be improved the resistive connection skin ability of water-based ink, reduces aqueous
The dirty version speed of ink, and then print speed printing speed and ink utilization efficiency are improved, achieve the purpose that save the cost.
The embodiment of the present application solves technical solution used by its technical problem:
A kind of anti-skinning auxiliary agent for water-based ink, in parts by weight, including following component:
Preferably, in parts by weight, including following component:
Preferably, in parts by weight, including following component:
Wherein, the triethanolamine, glycerine, urea and polyether modified siloxane are technical grade raw material or are point
Analyse grade raw material.
The embodiment of the present application also provides a kind of preparation methods of anti-skinning auxiliary agent for water-based ink, including walk as follows
It is rapid:
Water is first added into material cylinder, adds triethanolamine, moderate-speed mixer 3~10 minutes；
Under stirring, glycerine is slowly added into material cylinder, continues moderate-speed mixer 3~10 minutes；
Under stirring, continue after being slowly added to urea into material cylinder, then moderate-speed mixer 3~10 minutes；
Polyether modified siloxane, then moderate-speed mixer 5~15 minutes are slowly added to, keeps all stock dispersions uniform, obtains
Anti- skinning auxiliary agent.
Preferably, mixing time is 5 minutes in the step of addition triethanolamine, glycerine and urea；It is described to add
In the step of entering polyether modified siloxane, mixing time is 10 minutes.
Preferably, the moderate-speed mixer is 300~500 revs/min.
Preferably, all steps of the preparation method carry out at room temperature.
The embodiment of the present application also provides the anti-skinning auxiliary agents for water-based ink described in one kind in water-based ink
Using.
Specifically, the anti-skinning auxiliary agent is added in water-based ink, and stir 3~5 minutes, makes the anti-skinning auxiliary agent
It is dispersed in water-based ink；Wherein, the additive amount of the anti-skinning auxiliary agent is the 1%~3% of water-based ink quality.
The advantages of the embodiment of the present application, is:
1, the anti-skinning auxiliary agent of the application, due to using triethanolamine, glycerine, urea and polyether modified siloxane,
So that anti-skinning auxiliary agent integrates moisture absorption, moisturizing, lubrication, and since polyether modified siloxane can reduce surface tension,
Urea can form wetting protective film in the superficial layer of ink and therefore efficiently solve existing water-based ink superficial layer skinning
The problem of, the resistive connection skin ability of water-based ink is improved, reduces the dirty version speed of water-based ink, and then improve print speed printing speed and ink
Utilization efficiency achievees the purpose that save the cost.
2, the preparation method of the anti-skinning auxiliary agent of the application is simple, only need to sequentially add raw material, at room temperature with 300~
After 500 revs/min stir, the equipment used is conventional equipment, can be carried out at room temperature, operating procedure
It is simple and easy to implement, it can satisfy demand of industrial production.
3, additive amount of the anti-skinning auxiliary agent of the application in water-based ink is few, and mass fraction is added in water-based ink and is
1%~3% anti-skinning auxiliary agent is that can obviously improve the anti-skinning of water-based ink, will shut down or reduction of speed cleans the frequency of printing plate
It is reduced to every 2.5~3.0 hour/time from 1 hour/time, improves printing efficiency；And since water-based ink skinning speed reduces,
The water-based ink being sticked on printing plate greatly reduces, and also saves ink material, reduces production cost.
Specific embodiment
The embodiment of the present application solves aqueous oil in the prior art by providing a kind of anti-skinning auxiliary agent for water-based ink
The problem of black in press ink is easy skinning, improves the resistive connection skin ability of water-based ink, reduces the dirty version of water-based ink
Speed, and then print speed printing speed and ink utilization efficiency are improved, achieve the purpose that save the cost.
Technical solution in the embodiment of the present application is to solve the problems, such as that in press ink is easy skinning to above-mentioned water-based ink,
General thought is as follows:
