CN105062207A - Printing ink added with rosin resin and preparation method for printing ink - Google Patents

Abstract

The invention discloses printing ink added with rosin resin and a preparation method for printing ink. In a preparation process of plant oil type solvent printing ink, rosin resin is added to overcome the defect that the plant oil type solvent printing ink is not strong in adhesive force, so that the bonding strength of the printing ink is improved and the printing ink has a relatively good application prospect.

Description

A kind of ink adding Gum Rosin and preparation method thereof

Technical field

The present invention relates to a kind of 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, in order to overcome this shortcoming, this the present invention adds Gum Rosin preparing in ink process, increase viscosity, improve the bonding strength of ink, promote ink over-all properties.

Summary of the invention

The present invention carries a kind of ink adding Gum Rosin and preparation method thereof, and the preparation method of this ink carries 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 500-600r/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 Gum Rosin 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 Gum Rosin.

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 ink adhesion intensity is good;

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

Embodiment
