A kind of preparation method of rapid-curing cutback ink
Technical field
The present invention relates to a kind of preparation method of rapid-curing cutback ink.
Background of invention
Water color ink is with water as solvent or the ink of disperse medium, is mainly made up of binder, pigment and auxiliary agent etc..
With various paint, the development of coating, research and the application of water color ink have also obtained very big development.Although water color ink has
There is environmental protection, free from environmental pollution, the advantages of being harmful to human health, but as which is emerging ink, many performance studys are also
It is immature, many problems are remained in actual applications, so as to hinder its development to a certain extent.Due to aqueouss oil
, mainly with water as solvent, the boiling point of water is higher than the boiling point of common organic solvents for ink, thus when being dried, water color ink is dried
Time is longer than the drying time of solvent type ink.The speed of drying property directly affects the height of cost.It is dried too slowly, prolongs
The time of long production, can also increase cost.Water color ink rate of drying is excessively slow, causes print speed printing speed to reduce, extends manufacture cycle,
Cause ink when being transferred on printable fabric, ink is also dried completely, and dot gain is easily caused when of the same colour under chromatography,
Level is difficult to enrich.
The content of the invention
For solve ink the problems referred to above, the present invention employ in ink special process preparation be conducive to improve ink
The acrylic resin of dry rate, while also added ketone resin and waterborne polyurethane resin, further increases ink
Dry rate.
For achieving the above object, present invention employs following technical scheme:
A kind of preparation method of rapid-curing cutback ink, comprises the steps:
A) following component is weighed in terms of parts by weight:20 parts of ketone resins, 10 parts of waterborne polyurethane resins, 10 parts of acrylic acid
Resin, 40 parts of distilled water, 1 part of levelling agent, 1 part of defoamer, 0.5 part of antibacterial, 1.3 parts of diluent, in adding agitator, with
The speed of 350 turns/min, is sufficiently stirred for dispersion 30 minutes, treats each component mix homogeneously, and mixed liquor is obtained;
B) 50 parts of pigment are weighed in terms of parts by weight, 10 parts of silicon dioxide powders, 3 parts of mica powders, 10 parts of alumina powders are mixed
Close uniform, then feed the mixture into step 1)In obtained mixed liquor, add 3 weight portions lignin sulfonic acid, blender with
The speed of 400 turns/min is stirred 1 hour, then ground machine is fully ground, and is filtrated to get ink composite;
Described acrylic resin is adopted and is obtained with the following method:
In terms of parts by weight, 20 parts of ethanol are taken, 20 parts of propanol, 15 parts of isopropyl acetates add reactor after mix homogeneously
In, with the ramp of about 5-10 DEG C/min to 80 DEG C, 30min is incubated, 20 parts of ethyl acrylate, 10 parts of first are then sequentially added
Base acrylic acid, 15 parts of 2-(Acryloyloxy)ethanols, 2 parts of diacetone acrylamides, 1 part of azo diisopropyl imidazoline hydrochloride, stirring mixing are equal
Even, isothermal reaction 5 hours is cooled to 30 DEG C, and Deca 1.5ml strong aqua ammonia is stirred for 30min, obtains acrylic resin.
Described levelling agent is organosilicon levelling agent.
Described defoamer is BYK-016.
Beneficial effect:
1) water-dispersible acrylic's resin is contained in ink of the invention, which has good adhesive force, rate of drying
Hurry up, as one of the film-forming components of ink, the dry rate of ink film can be significantly improved.2) also make in ink of the invention
With beneficial to the ketone resin and waterborne polyurethane resin for improving dry rate, which is cooperateed with acrylic resin, is further improved
The dry rate of ink film.3)The rate of drying water color ink faster of the present invention, can significantly reduce water color ink and be dried speed
The printing quality problem that degree is brought slowly, reduces production cost, and there is actual application value pole.
Specific embodiment
The present invention will be further described with reference to embodiments, but the scope of protection of present invention is not limited to reality
Apply the scope of example expression.
Embodiment 1

Speed, tack evaluation are dried to above-mentioned each ink, it is as a result as follows:
Drying property evaluation method:Each ink is printed to place 1 hour after leaflet, covering paper tape is then sticked and is applied
Pressure, paper tape is opened, and determines the printing ink transfer amount on paper tape, evaluation is divided into 3 grades:
Well:Almost without in ink transfer to paper tape;Typically:Only locally there is a small amount of ink transfer to paper tape;
Difference:There are many places and substantial amounts of ink transfer is on paper tape.
