CN104177911A - Pliable easily-attached printing ink containing alcohol-soluble protein - Google Patents

Abstract

The invention relates to the field of printing ink and particularly relates to pliable easily-attached printing ink containing an alcohol-soluble protein. The printing ink is prepared from the following raw materials in parts by weight: 2-4 parts of zinc stearate, 4-5 parts of tetraethylene glycol, 0.1-0.2 part of lavandin oil, 1-3 parts of anhydrous magnesium sulfate, 2-4 parts of alcohol-soluble protein, 30-32 parts of rosin-modified alkyd resin, 8-12 parts of organic pigment, 30-45 parts of propylene glycol methyl ether acetate, 10-12 parts of isopropanol and 2-4 parts of auxiliaries. The printing ink disclosed by the invention is low in toxicity and environment-friendly, fewer in toxic volatile components of organic matters and small in harm on environment and human body, and takes the rosin-modified alkyd resin as a connecting material; the added alcohol-soluble protein can be used for improving the toughness and viscidity of the pigment, so that the rheological property of the printing ink is finally improved; the raw materials such as zinc stearate and lavandin oil are combined, so that the printing ink prepared in the invention has good flexibility, and can be attached with a basal body very well during printing to avoid uneven coloring; and moreover, with the unique lavender fragrance, the printed products are elegant and graceful, and strong in market competitiveness.

Description

A kind of pliable and tough printing-ink that easily adheres to containing prolamine

Technical field

The present invention relates to printing-ink field, be specifically related to a kind of pliable and tough printing-ink that easily adheres to containing prolamine.

Background technology

Printing-ink is a kind of common printed matter coloured material, mainly formed by compositions such as pigment, low-melting ink vehicle, stopping composition, and be the pulpous state adherent that a class is coloured, have certain degree of mobilization.Want to obtain gratifying printing effect, color to ink in actual use procedure, printing adaptability, rate of drying has certain requirement, also to possess according to environment for use water-fast simultaneously, fast light, acid and alkali-resistance, the features such as low toxic and environment-friendly, following printing-ink developing direction must be towards low toxicity, quick-drying, the future development of the naturally various and multifunction of color, but the inadequate environmental protection of existing ink ubiquity, viscosity control inequality, the not good and good ink of the partial properties shortcoming such as hold at high price with base material sticking power, therefore, the composition and engineering of necessary improvement printing-ink, the transition of quickening industry, to reach the production model of high-efficiency environment friendly.

Summary of the invention

The object of the invention is to, a kind of pliable and tough printing-ink that easily adheres to containing prolamine is provided, the use properties of improving ink with it, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of pliable and tough printing-ink that easily adheres to containing prolamine, it is characterized in that, this ink is made up of the raw material of following weight part: Zinic stearas 2-4, tetraethylene-glycol 4-5, lavandin oil 0.1-0.2, anhydrous magnesium sulfate 1-3, prolamine 2-4, rosin modified alkyd resin 30-32, pigment dyestuff 8-12,1-Methoxy-2-propyl acetate 30-45, Virahol 10-12, auxiliary agent 2-4;

In described auxiliary agent, comprise the raw material of following weight part: emulsifier op-10 2-4,2-pyridine carboxylic acid 0.1-0.2, naphthenic acid rare earth 1-2, dehydrated alcohol 10-15, graphene oxide 5-8, preparation method is: first 2-pyridine carboxylic acid, naphthenic acid rare earth are added in dehydrated alcohol, after dispersed with stirring 20-30min, add again graphene oxide, mixture ball milling 1-2h after stirring, add subsequently other remaining component, continue to stir 20-30min, to obtain final product.

Described a kind of pliable and tough printing-ink that easily adheres to containing prolamine, its preparation method is as follows:

(1) first prolamine is dissolved in Virahol, and Zinic stearas, pigment dyestuff are dropped in solution, mix rear mixture ball milling 1-2h, gained material is for subsequent use;

(2) step (1) gained material is mixed with other remaining component, drop in homogenizer, after the rotating speed dispersed with stirring 60-80min of 1200-1500 rev/min, again compound is dropped into ball-milling processing in ball mill, the particle diameter that makes gained slurry is 5-25 μ m, and adjusting viscosity as required, to obtain final product.

Ink advantage prepared by the present invention is: the principle of first having followed low toxic and environment-friendly in the preparation of raw material, toxic organic compound volatile component is wherein few, harm to environment and human body is little, using rosin modified alkyd resin as low-melting ink vehicle, there is good use properties, prolamine in raw material can improve toughness and the viscosity of pigment dyestuff simultaneously, finally improve the rheological of ink, again in conjunction with Zinic stearas, the raw materials such as lavandin oil, make ink prepared by the present invention there is good snappiness, when printing can with matrix good fit, avoid painted inequality, and there is unique lavandula angustifolia fragrance, printed matter is elegant and graceful, the market competitiveness is strong.
