Abstract

The invention discloses a preparation method of a thickening-resin-added ink, which comprises the following steps: adding 20% of water, 25% of vegetable oil, 15% of ethanolamine, 0.5% of organosilicon defoaming agent and 1% of soybean lecithin wetting agent into a dispersion cylinder, uniformly dispersing at the speed of 500-600 r/min for 1-2 hours, and filtering the liquid; and collecting the filtered emulsion, pouring into the dispersion cylinder, sequentially adding 25% of water-soluble acrylic resin, 3% of maleic rosin resin and 10% of water-based acrylic color paste, uniformly dispersing at the speed of 600-800 r/min for 2-4 hours, finally adding 0.5% of organosilicon defoaming agent, and filtering to obtain the product. Certain acids of the common rosin resin contain the conjugated double bond, and thus, the rosin resin added into the ink can lower the stability of the ink. The maleic rosin resin added in the invention enhances the bonding strength of the ink, and has favorable stability.

Description

A kind of compound method of adding the ink of resin of thickening

Technical field

The present invention relates to a kind of novel ink, particularly a kind of environment-friendlyink ink and preparation method thereof, belong to ink chemical field.

Summary of the invention

Along with the development of press, ink application is also increasingly extensive, output constantly increases, China's ink industry in 2010 is produced and is reached all-time high, " Chinese ink industry production and marketing demand and investment forecasting analysis report are looked forward to the prospect " adds up, whole nation ink gross annual output amount amounts to 58.99 ten thousand tons, accounts for 14% of the whole world, exceedes Germany first, Japan occupies the second in the world.

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.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.Along with the attention degree of environmental protection is increasing, the reinforcement of Green Packaging concept, 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.

Solvent is made with vegetables oil, not only environmental protection but also the resource of available regenerative replaced non-renewable petroleum solvent to the ink of preparation, and when reclaiming, than traditional ink, deinking is easier to useless printed matter process, little to the damage of paper, but vegetable oil solvent adhesive power is not strong, preparing in ink process by adding Gum Rosin, the viscosity of ink can be increased, improve the bonding strength of ink.Some acid in rosin is containing conjugated double bond, therefore reactivity is higher, unstable, oxidizable.Maleated rosin, also known as toxilic acid with addition of compound, be that toxilic acid joins with rosin take benzene as solvent, carries out the addition product reacted under strong acid exists.Add maleated rosin resin preparing in ink process, as tackifying resin, ink adhesion intensity can be improved, and stability is good, there is good application prospect.

Summary of the invention

The invention provides a kind of compound method of adding the ink of resin of thickening, the method is carried out as follows:

With one dispersion cylinder load 20% water, 25% vegetables oil, the thanomin of 15%, the silicone antifoam agent of 0.5% and 1% soybean lecithin wetting agent;

(2) press the rotating speed of 500-600 r/min, dispersed 1-2 hour;

(3) after dispersion, by liquid filtering;

(4) collect the emulsion of filtration, then pour in dispersion cylinder, add the water soluble acrylic resin of 25%, the maleated rosin resin of 3%, the water soluble acrylic acid mill base of 10% successively, by the rotating speed of 600-800r/min, dispersed 2-4 hour;

(5) filter after finally adding the silicone antifoam agent of 0.5%, a kind of interpolation maleated rosin resin ink.

The present invention has following advantages and characteristic:

(1) this ink adhesion intensity is good;

(2) the Gum Rosin good stability added;

(3) raw material sources are extensive, with low cost.
