Abstract

The invention relates to a polymerized-rosin-modified-phenolic-resin-added ink and a preparation method thereof. The method comprises the following steps: sequentially mixing 25% of soybean vegetable oil, 20% of water, 15% of ethanolamine, 1% of soybean lecithin and 0.5% of organosilicon in a dispersion container, dispersing, filtering, collecting the filtered emulsion, adding 25% of water-soluble acrylic resin, 10% of water-based acrylic color paste and 3% of polymerized-rosin-modified phenolic resin, dispersing, adding an organosilicon defoaming agent, and filtering to obtain the polymerized-rosin-modified-phenolic-resin-added ink.

Description

A kind of ink and compound method thereof of adding polymerized rosin modified phenolic resins

Technical field

The present invention relates to a kind of novel ink, particularly a kind of ink and compound method thereof of adding modified rosin resin, belongs 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, adopt pure natural soybean plants oil, the ink that resin and gelifying agent are made, printing color is bright-coloured, gloss is high, by force wear-resisting, printing transitivity is better, and it is more excellent for manufacture paper product degradation property, there is better deinking, but vegetable oil solvent adhesive power is not strong, preparing in ink process by adding Gum Rosin for this reason, the bonding strength of ink can be improved, the acid number of rosin self is higher, poor heat stability, add in ink, the stability of ink can be reduced.The present invention, by adding polymerized rosin modified phenolic resins, can provide additive effect, adds polymerized rosin modified phenolic resins preparing in ink process, not only can improve ink adhesion intensity, stability is good, and the water resistance of ink also will improve, and has better application prospect.

Summary of the invention

The invention provides a kind of ink and compound method thereof of adding polymerized rosin modified phenolic resins, the method is carried out as follows:

With one dispersion cylinder load 20% water, 25% soybean plants 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 2-3 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 polymerized rosin modified phenolic resins 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 ink adding polymerized rosin modified phenolic resins.

The present invention has following advantages and characteristic:

(1) high, the good stability of this ink adhesion intensity;

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