Abstract

The invention provides soy ink and a method for preparing the same. The ink comprises the following components according to weight percentage: 20 to 40% of industrial soy oil, 10 to 20% of ethanolamine, 20 to 30% of water soluble acrylic resin, 10 to 20% of water-based acrylic color paste, 1 to 2% of a soybean lecithin wetting agent, 1 to 2% of an organic silicon defoamer, and the balance of water. The prepared oil is excellent in environmental performance, and pure and saturated in color.

Description

A kind of soya-bean ink and preparation method thereof

Technical field

The present invention relates to a kind of ink, particularly a kind of vegetables oil that utilizes is as the environment-friendly ink of solvent, belongs to ink manufacture field.

Summary of the invention

Ink is a kind of to be mixed equably by pigment, low-melting ink vehicle and auxiliary agent etc. and through the gluey fluid of a kind of viscosity of repeat-rolling.It is the important materials for wrapping material printing, such as, for fields such as books and periodicals, packing and decorating, building decorations by printing by pattern, literal table now on the substrate.The U.S. is maximum ink producing country and country of consumption in the world, and Japan takes second place, and Germany the 3rd, China occupies the 4th.Along with the develop rapidly of Chinese national economy, the fast development of China's nearly ten years packaging industries, make the ink industry of China have also been obtained larger expansion, emerge rapidly and become one of ink manufacture big country of the world, current domestic ink industry size just maintains sustained and rapid growth with the speed of more than 10%.

Develop the ink kind of various performance in recent years, along with the attention degree of environmental protection is increasing, have the regulation limitations such as heavy metal content, packing material solvent residues amount and other VOC limit standard in other related fields such as food product pack especially, exploitation non-toxic ink is the study hotspot of current ink.

In China, what ink production was produced substantially is traditional synthetic resins ink, containing the high point petroleum solvent of 35% ~ 40% in this kind of ink, thus containing more multiring aromatic hydrocarbon substance, and 3,4-benzo pyrroles, 3-nitro benzo ketone etc. are wherein also containing carcinogenic components, on printed matter, residual quantity is large, the survival time is long, can endanger user's health, is also the important source of pollution in Printing ink producing process simultaneously.In today that environmental pollution attracts people's attention day by day, non-toxic ink replaces traditional ink will be inexorable trend.Soya-bean ink is owing to adopting the soy resins of natural environmental-protective as matrix resin, and VOC content is low, and having the various features such as the upper machine stability of biological degradation and excellence and good post-press finishing, is the leading role of following environment-friendly ink.

Non-renewable petroleum solvent is replaced with this not only environmental protection of soybean oil but also the resource of available regenerative; and when reclaiming, than traditional ink, deinking is easier to useless printed matter process; little to the damage of paper, the waste residue after deinking is also better degraded, and is a measure being of value to protection of the environment.The invention provides a kind of Soybean Oil Ink and preparation method thereof, this ink can be widely used in packing and decorating printing, to beautifying printed matter, improving added value of product, having immeasurable effect.

Summary of the invention

The invention provides a kind of soya-bean ink and preparation method thereof, for realizing this purpose, this ink comprises the material of following weight percent:

Industry soybean plants oil 20-40%

Thanomin 10-20%

Water soluble acrylic resin 20-30%

Water soluble acrylic acid mill base 10-20%

Soybean lecithin wetting agent 1-2%

Silicone antifoam agent 1-2%

Water surplus.

The preparation method of this ink carries out as follows:

(1) load a certain proportion of water, industrial soybean plants oil, thanomin and silicone antifoam agent by a dispersion cylinder, by the rotating speed of 500-600 r/min, dispersed 1-2 hour;

(2) after dispersion, then add appropriate silicone antifoam agent, filter;

(3) the emulsion of filtration is put in dispersion cylinder more again;

(4) add water soluble acrylic resin, water soluble acrylic acid mill base, soybean lecithin wetting agent and silicone antifoam agent more successively, by the rotating speed of 600-8000r/min, dispersed 2-4 hour;

(5) filter after finally adding appropriate silicone antifoam agent, a kind of soya-bean ink.

Step (4) in, in described water soluble acrylic acid mill base, the color of pigment powder is one or more in red, yellow, blue, black.

The present invention has following advantages and characteristic:

(1) this water-based soya-bean ink has excellent double exposure;

(2) color is pure, look full;

(3) good environmental protection;

(4) raw material sources are extensive and renewable, reduce the dependence to Nonrenewable resources.
