Abstract

The invention relates to printing ink composition with addition of cobalt iso-octoate and a preparation method of the printing ink composition. The printing ink comprises components as follows: 20%-40% of vegetable fat, 10%-20% of ethanol amine, 10%-15% of fumaric acid modified rosin polycondensate, 10%-15% of waterborne acrylic resin, 10%-20% of waterborne acrylic color paste, 1%-2% of a soybean lecithin wetting agent, 1%-2% of an organic silicon defoamer, 1%-2% of cobalt iso-octoate and the balance of water. The cobalt iso-octoate drying aid is added in a preparation process of the printing ink, so that a better drying assistant effect can be realized, and the modified printing ink is obtained.

Description

It is a kind of to add the modified ink composite of cobalt iso-octoate

Technical field

The present invention relates to a kind of ink, more particularly to a kind of ink composite of addition cobalt iso-octoate and preparation method thereof, Belong to ink manufacture field.

Background technology

Ink is that one kind is equably mixed by pigment, link stuff and auxiliary agent etc. and Jing repeat-rollings form a kind of viscosity glue Fluid.It by printing pattern, word are shown on stock, be the important materials for packages printing.In China, ink Industry size is just maintained sustained and rapid growth with more than 10% speed, and having emerged rapidly becomes one of ink manufacture big country of the world.

Conventionally manufactured ink is the raw material using industrial Petropols as ink, will be contained mostly organic in this kind of ink (or inorganic) solvent, thus containing more multiring aromatic hydrocarbon substance, and therein 3,4- benzo pyrrole, 3- nitro benzo ketone etc. are also Containing carcinogenic components, on leaflet, residual quantity is big, and the survival time is long, can endanger user health.

As the security requirement that the environmental consciousness of people strengthens and people are printed to packaging for foodstuff is improved, ink industry is Jing is occurred in that from traditional solvent-borne ink to such as water-based flexographic ink, Soybean Oil Ink, environment-friendly ink as UV ink turn The trend of shifting.The exploitation of environment-friendly ink and production capacity have become one of following key factor won victory of ink manufacturers. Make solvent with vegetable oil, not only resource that is environmentally friendly but also can use regeneration replaces non-renewable petroleum solvent to the ink of preparation, and reclaims When useless leaflet processed be easier to deinking than traditional ink, but plant oil base contains a large amount of unsaturated fatty acids, is dried speed Degree is slow.

In order to overcome the dry slow-footed shortcoming of vegetable oil backbone, the present invention is by, in ink-making process, adding different pungent Sour cobalt drying aids, cobalt iso-octoate are used in ink, can preferably be urged dry effect, the promotion that isooctyl acid is estimated under normal circumstances Effect is better than cobalt naphthenate, is added in ink, can promote the consaturated oil generation oxidation in vegetable oil solvent, from liquid Become solid-state, macromole is become by small molecule, so as to accelerate oils and fatss conjunctival xerosiss, ink is overcome in the shortcoming of slow drying speed.

The content of the invention

The present invention provides a kind of ink prepared using addition cobalt iso-octoate drier, and the ink includes following components：

Vegetable oil lipoprotein 20-40%

Ethanolamine 10-20%

Fumaric acid modified rosin polycondensate 10-15%

Water soluble acrylic resin 10-15%

Water soluble acrylic acid mill base 10-20%

Soybean lecithin wetting agent 1-2%

Organic silicon defoamer 1-2%

Cobalt iso-octoate 1-2%

Water surplus.

The preparation method of the ink of said components content comprises the steps：

(1) take a container, put into a certain proportion of Vegetable oil lipoprotein, ethanolamine, organic silicon defoamer and soybean lecithin wetting agent and Suitable quantity of water mixes, and is heated to uniform temperature；

(2) keep under steady temperature, mixed solution is mixed with agitator, is uniformly dispersed；

(3), after disperseing, a certain amount of water soluble acrylic resin, fumaric acid modified rosin polycondensate and aqueous acrylamide are sequentially added Acid color slurry；

(4) mixed solution system is mixed under certain rotating speed, be uniformly dispersed；

(5) a certain amount of cobalt iso-octoate and organic silicon defoamer are subsequently adding；

(6) finally filtered with filter, collect filtrate, you can obtain a kind of quick-drying ink.

Preferentially, step (1) in, Vegetable oil lipoprotein is soybean oil.

Preferentially, step (2) in, heating-up temperature be 40-50 DEG C.

Preferentially, step (2) in, agitator presses the rotating speed of 500-600 r/min, dispersed 2-3 hours.

Preferentially, step (4) in, agitator presses the rotating speed of 600-800r/min, dispersed 3-5 hours.

The present invention has following advantages and characteristic：

(1) rate of drying is fast；

(2) flow process is simple, easy to operate, easy to use；

(3) drying aids usage amount is few, low cost.
