Abstract
The invention relates to a formula of lithographic offset printing ink. The formula comprises the following components in percentage by mass: 30-50% of pigment, 10-30% of binder, 10-40% of filler and 5-20% of additional material, wherein the pigment is an organic pigment, the binder is prepared by dissolving natural resin, synthetic resin, cellulose and rubber derivatives in drying oil or a solvent, the filler is one or more selected from calcium carbonate, magnesium carbonate, barium sulfate, aluminum hydroxide, aluminum silicate and lithopone and the additional material comprises a desiccant, a diluent, a withdraw adhesive and a plasticizer. The formula of the ink is stable and reliable, and has the characteristics of good smoothness and bright color; during use, the color can be maintained in longer time, ingredients used are nontoxic and harmless and have an environment-friendly effect, and the used materials are convenient in sampling and suitable for printing.
Description
Technical field
The present invention relates to a kind of offset lithographic ink formulations, belong to printing technology.
Background technology
The manufacture of ink is a complicated chemical engineering, and its material has related to organic polymer and synthesized and redox, diazotization, replacement(metathesis)reaction, the chemical transformation such as complex reaction.Meanwhile, relate to mechanics, optics, chromatism, surface chemistry etc. and learn material.The firstth, the manufacture of various pigment and the manufacture of stopping composition.The secondth, the manufacture of various synthetic resins and the production of various types of low-melting ink vehicles, be dissolved in solid resin in vegetables oil, Dormant oils, solvent medium.The 3rd is the manufacture of ink.These three processes are to be mutually related, interactive, indispensable.In offset printing process, also higher to the specification of quality of ink, not only require to meet certain viscosity, also will have certain work-ing life and hue preserving, therefore, ink formulations often relates to plurality of raw materials composition, composition used not necessarily, also causes ink quality otherness obvious.
Summary of the invention
The object of the present invention is to provide a kind of offset lithographic ink formulations, to can prepare steady quality, flexographic ink formula easy to use, improves the effect of offset lithographic with this, extends ink functional quality and stability.
To achieve these goals, technical scheme of the present invention is as follows.
An offset lithographic ink formulations, is comprised of pigment, binder, filler, additional material, and it is that pigment accounts for 30～50% according to mass percent that above-mentioned each component forms, and binder accounts for 10～30%, filler accounts for 10～40%, additional material accounts for 5～20%.
Further, described pigment is pigment dyestuff, and this pigment dyestuff comprises one or several in sylvic oil, gummy oil or refining long oil alkyd.Wherein, resin oil viscosity is 33000-43000mPas at 25 ℃, and colloid oil viscosity is 100000-200000mPas at 25 ℃.
Further, described binder is that natural resin, synthetic resins, Mierocrystalline cellulose, rubber derivative are dissolved in siccative oil or solvent and make.
Further, described filler be in calcium carbonate, magnesiumcarbonate, barium sulfate, aluminium hydroxide, gloss white or pure aluminium silicate one or several.
Further, described additional material comprises siccative, thinner, removes stick, softening agent, described siccative is the organic or inorganic compound containing cobalt, manganese, lead, zinc, iron, calcium, vanadium, zirconium metallic element, and described thinner is one or several in aluminium hydroxide, barium sulfate or titanium dioxide; Described remove stick be in aluminum stearate, eight aluminium carbonates, oleum lini, low-viscosity Synolac or paraffin oil one or several; Described softening agent is polyvinyl chloride or phthalic ester.
In this invention formula, each several part effect is as follows:
(1) pigment: pigment plays coloration in ink, it has the direct powder that affects the high degree of dispersion of colour, black or white that pigment is water insoluble and organic solvent to some characteristics of ink again.Of the present invention is pigment dyestuff, and wide in variety, color is more complete, and performance is better than mineral dye.Dyestuff is organic compound, and its water soluble is also dissolved in organic solvent sometimes.The pigment using in printing-ink is required quite high, particularly color, dispersity, photostabilization, transparency etc., require the tone of coloured pigment to approach spectral color, saturation ratio should be large as far as possible, three-colour printing ink magenta used, green grass or young crops, yellow ultramarine transparency must be high, and all pigment is not only wanted water tolerance, and will be quickly and evenly and binder combination, the oil absorption of pigment should be too not large, and pigment preferably has the performances such as alkaline-resisting, acidproof, resistance to alcohol and resistance to gesture.
(2) binder: binder is the chief component composition of ink, plays dispersed color, give ink suitable clinging, mobility and transfer printing performance, and by film forming, make pigment be bonded to the effect of printed matter surface after printing.The rheological of ink, viscosity, neutrality, acid number, color and luster, water resisting property and printing performance etc. depend primarily on binder, and same pigment, is used different binders, can be made into dissimilar ink; And same binder is used different pigment.Made is still the ink of same type, because it can not change the basic performance of ink, so the quality of ink, except outside the Pass having with pigment, depends primarily on binder.
(3) filler: filler is white, transparent, translucent or uncomfortable bright flour.The main packing action that rises, filling pigment part, suitably adopts a little fillers, both can reduce amount of pigment, reduce costs, the character of adjustable ink again, as rare thick, mobility etc., the handiness that also improves formulating of recipe.
(4) additional material: additional material is in ink manufacture, and in printing is used, for improving some additional materials of performance of ink itself.Ink by essentially consist preparation, still can not meet the demands aspect some characteristic, or due to the variation of condition, and the printing that can not meet is used while requiring, and must add a small amount of subsidiary material to solve.Additional material has many, as: siccative, thinner, remove stick, softening agent etc.
This beneficial effect of the invention is: above-mentioned ink formulations, and reliable and stable, fluency is good, bright-colored, in use procedure, can stand the maintenance color of longer time, and composition used is nontoxic, there is environmental-protection function, and material used sampling is convenient, is applicable to printing and uses.
