Abstract
The invention provides a wear-resistant offset printing ink prepared from the following raw materials in parts by weight: 6-8 parts of propylene glycol methyl ether acetate, 2-2.5 parts of nano zinc oxide, 2-3 parts of polytetrafluoroethylene micropowder, 30-35 parts of rosin modified phenol-formaldehyde resin, 0.1-0.2 part of oxo-2-ethylhexanoato-o aluminum homopolymer, an appropriate amount of mineral oil, 50-55 parts of soybean oil, 0.1-0.2 part of tert-butyl hydrogen peroxide, 20-30 parts of a colorant, 1-2 parts of lanthanum ethylhexanoate, 1-1.5 parts of pentaerythritol ester, 1.3-1.6 parts of methyl methacrylate, 2-3 parts of acrylic acid, 1-2 parts of lac and 1-2 parts of polymeric castor oil. According to the offset printing ink provided by the invention, the soybean oil is used for replacing most of petroleum solvents in the traditional ink to ensure that the VOC (volatile organic compound) is reduced to be less than 15%, and nano zinc oxide is added to catalyze oxidation reaction and promote drying, so that the glossiness and toughness of the ink are improved. The ink is quick to oxidize and dry and cannot cause 'skin formation' in an ink fountain of an offset printing machine, and a film is quick to form.
Description
Technical field
The present invention relates to flexographic ink field, particularly relate to a kind of wear-resisting flexographic ink and preparation method thereof.
Background technology
Flexographic ink is mainly by the coloured material of the flow-like of pigment, auxiliary agent, high molecular polymer and solvent composition, and wherein, the primary solvent of flexographic ink is mineral oil and vegetables oil.The flexographic ink drying process be printed onto on paper is very complicated, and we can be understood as ink is undertaken dry by the oxidation filming of mineral oil infiltration and vegetables oil.
Since having flexographic ink, in flexographic ink, lack the existence that can't do without mineral oil all the time.Usually, be 25%-45% at the content of common flexographic ink mineral oil in fluid.Mineral oil is the Nonrenewable resources extract from oil, wherein containing harmful arene material.
Now, some ink enterprises successfully develop Soybean Oil Ink, make VOC (organic volatile) content be reduced to less than 15% from 30%-60%, greatly reduce the pollution of environment and be beneficial to health of human body, there is good theoretical significance and using value.But because soybean oil belongs to semi-drying oil, there is the problems such as ink dryness is poor, ink-water balance difficult control when substituting the petroleum solvent in traditional ink by soybean oil, the low inferior problem of production efficiency, therefore need to improve.
Also there are some rheological problems in current soybean oil offset ink, as thixotropy, tackyness, yield value, also has the performance needs such as rub resistance, splitting resistance, germ resistance, persistence to improve.
Summary of the invention
The object of the present invention is to provide a kind of wear-resisting flexographic ink, this flexographic ink makes VOC be reduced to less than 15%, glossiness high, good toughness, thixotropy is good, and wear resistance is good, water-tolerant, and air drying is fast, in offset press ink fountain not " skinning ".
Technical scheme of the present invention is as follows:
A kind of wear-resisting flexographic ink, is characterized in that being made up of the raw material of following weight part: propylene glycol methyl ether acetate 6-8, nano zine oxide 2-2.5, ptfe micropowder 2-3, rosin modified phenolic resin 30-35, oxo-2 ethyl hexanoic acid root closes that the homopolymer 0.1-0.2 of aluminium, Dormant oils are appropriate, soybean oil 50-55, tertbutyl peroxide 0.1-0.2, tinting material 20-30, isocaprylic acid lanthanum 1-2, pentaerythritol ester 1-1.5, methyl methacrylate 1.3-1.6, vinylformic acid 2-3, shellac 1-2, polymerized castor oil 1-2.
The production method of described wear-resisting flexographic ink, is characterized in that:
(1) by soybean oil, polymerized castor oil, pentaerythritol ester, methyl methacrylate, vinylformic acid, nano zine oxide mixing and stirring, be warming up to 60-70 DEG C, add tertbutyl peroxide, stir 20-30 minute, obtain soybean oil solvent;
(2) send in reactor by rosin modified phenolic resin, propylene glycol methyl ether acetate, shellac, soybean oil solvent, stir and be warming up to 170-180 DEG C, do not stop to stir insulation 2-2.5 hour, naturally cooling, obtains sylvic oil;
(3) homopolymer oxo-2 ethyl hexanoic acid root being closed aluminium adds appropriate mineral oil, is mixed with the aluminium oil that aluminium content is 3%;
(4) sylvic oil is heated to 75-80 DEG C, drip aluminium oil, dropping limit, limit is stirred, and adds aluminium oil before 90 DEG C, continues warming while stirring to 175-180 DEG C, and insulation 40-50 minute, naturally cools to room temperature, obtain binder;
(5) binder is mixed with other remaining components, feeding three-roller is ground to the fineness that ink specifies, obtains final product.
Beneficial effect of the present invention
Flexographic ink of the present invention instead of the most of petroleum solvent in traditional ink by use soybean oil, make VOC be reduced to less than 15%, by adding nano zine oxide, catalytic oxidation, promoting dry, improve glossiness and the toughness of ink; By adding the material such as tertbutyl peroxide, vinylformic acid in soybean oil, through polymeric modification, improve the thixotropy of ink, yield value and drying property.By adding ptfe micropowder, improve the wear resistance of ink, water tolerance.This printing ink oxidization conjunctival xerosis is fast, in offset press ink fountain not " skinning ".
