CN105017853A - Processing method of ink added with dihydro rosin resin - Google Patents

Abstract

The present invention discloses a processing method of an ink added with dihydro rosin resin, during the preparation of a vegetable oil based solvent ink, by addition of the dihydro rosin resin, the shortcomings that some acids in rosin contain conjugated double bonds, is unstable, and is easy to oxidize can be overcome, and the adding effect of the rosin is improved.

Description

A kind of working method of adding dihydro Gum Rosin ink

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.For this reason, the present invention, in order to improve the additive effect of rosin, adds dihydro rosin preparing in ink process, improves the additive effect of rosin.

Summary of the invention

The present invention puies forward a kind of working method of adding dihydro Gum Rosin ink, and the working method of this ink 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 dihydro 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 interpolation dihydro Gum Rosin 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 ink adhesion intensity is good;

(2) the Gum Rosin good stability added;

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