The invention relates to an offset printing ink containing titanium dioxide nanofibers. The offset printing ink is prepared from the following raw materials in parts by weight: 1.5-2 parts of molybdenum dioxide, 2-3 parts of 4-isopropyl thioxanthone, 1-1.5 parts of ethyl 4-dimethylaminobenzoate, 0.5-0.8 part of titanium dioxide nanofibers, 0.5-0.7 part of sodium fluosilicate, 30-35 parts of rosin modified phenolic resin, 0.1-0.2 part of (2-ethylhexanoato-o)oxo-aluminum homopolymer, a right amount of mineral oil, 60-65 parts of soybean oil, 3-4 parts of linseed oil, 0.1-0.2 part of tert-butyl hydroperoxide, 20-30 parts of coloring agents, 1-2 parts of lanthanum iso-octoate, 1.3-1.6 parts of methyl methacrylate and 2-3 parts of acrylic acid. The offset printing ink disclosed by the invention can be used for enhancing the thixotropy of ink and the abrasion resistance of the ink through polymeric modification by adding materials, namely the titanium dioxide nanofibers, the acrylic acid and the like to the soybean oil as well as preventing the phenomenon of skinning of the ink and increasing the printing speed by virtue of the added molybdenum dioxide.
Description
Technical field
The present invention relates to flexographic ink field, particularly relate to a kind of flexographic ink containing titanium dioxide nanofiber 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 flexographic ink containing titanium dioxide nanofiber, this flexographic ink wear resistance is good, and fast drying, print speed is fast.
Technical scheme of the present invention is as follows:
A kind of flexographic ink containing titanium dioxide nanofiber, it is characterized in that being made up of the raw material of following weight part: molybdenum dioxide 1.5-2, 4-isopropyl thioxanthone 2-3, to dimethylaminobenzoic acid ethyl ester 1-1.5, titanium dioxide nanofiber 0.5-0.8, Sodium Silicofluoride 0.5-0.7, rosin modified phenolic resin 30-35, oxo-2 ethyl hexanoic acid root closes the homopolymer 0.1-0.2 of aluminium, Dormant oils is appropriate, soybean oil 60-65, oleum lini 3-4, tertbutyl peroxide 0.1-0.2, tinting material 20-30, isocaprylic acid lanthanum 1-2, methyl methacrylate 1.3-1.6, vinylformic acid 2-3.
The production method of the described flexographic ink containing titanium dioxide nanofiber, is characterized in that:
(1) by soybean oil, oleum lini, molybdenum dioxide, 4-isopropyl thioxanthone, to dimethylaminobenzoic acid ethyl ester, titanium dioxide nanofiber, Sodium Silicofluoride, methyl methacrylate, vinylformic acid 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, 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, VOC is made to be reduced to less than 15%, by adding the material such as titanium dioxide nanofiber, vinylformic acid in soybean oil, through polymeric modification, improve the thixotropy of ink, add the wear resistance of ink, promote ink setting; By adding molybdenum dioxide, ink skinning can be prevented, improving print speed.
