Abstract
The invention relates to an environment-friendly anti-dryer and a preparation method thereof. The environment-friendly anti-dryer is prepared by raw materials of, by mass, 15%-20% of antioxidant 2246, 10%-15% of food grade phenol antioxidants, 40%-50% of dioctyl phthalate and 20%-30% of high boiling point solvent oil, and the preparation method includes heating the dioctyl phthalate to 35 DEG C to 60 DEG C, slowly adding tertiary butyl hydroquinone in a thermal insulation state for a fully stirring until a mixture is completely dissolved, adding dioctyl adipate, slowly adding an antioxidant 2246 for the fully stirring until a mixture is completely dissolved at the temperature between 80 DEG C and 90 DEG C, and continuously stirring for 40-60 minutes in the thermal insulation state so as to guarantee that the antioxidant is uniformly distributed in a solvent to obtain a finished product. According to the environment-friendly anti-dryer and the preparation method thereof, the problems that the yellow ink turns green and blue ink is rusted and the like are effectively solved, the anti-dryer is almost insoluble in water, thereby the anti-dryer has no negative effect on water-ink balance and is safe and environment-friendly, the smell is small, the intermiscibility of the anti-dryer and ink is good, the antioxidant efficiency is high, and ink can opening time and retention time of the ink on a printer can be effectively prolonged.
Description
Technical field
The invention belongs to printing ink and paint field, relate to anti-siccative, anti-siccative of especially a kind of environment-friendly type and preparation method thereof.
Background technology
At present, the surface crusting phenomenon in use, easily occurs in printing ink and coating.In order to address this problem, usually will add anti-siccative, but the anti-oxidant efficiency of existing anti-siccative is lower, its proterties is lotion or solid mostly, poor with the intermiscibility of printing ink; Simultaneously, some iron ions are always arranged in printing ink, oxidation inhibitor is color reaction when running into iron ion, and colour-change is very dark.Especially existing phenols antiskinning agent, larger on the impact of the dryness of coating, will make after the coating brushing in several days not conjunctiva as consumption is slightly improper, easily yellowing in addition, and react and be brown with iron ion, there are in addition some pungent tastes.
The oxidation inhibitor solvability is divided into fully dissolves, is partly dissolved, does not dissolve fully.The good antioxidant effect that generalized case and printing ink dissolve is good; Another kind of phenomenon is exactly compatibility, two kinds or above material mixing, and the general antioxidant effect that compatibility is good is good.The height of antioxygen efficiency is to have the chemical structure of oxidation inhibitor to determine, but the efficiency difference that same oxidation inhibitor reacts in different printing ink, so to find out the oxidation inhibitor relatively matched through overtesting, in order to reach best effect.
Flexographic ink is in press wished slow curing on machine, to quick-drying on paper.Wish three kinds of modes and offset the effect of oxidation inhibitor: in printing process, oxidation inhibitor has volatilization phenomenon, printing ink to print to that oxidation inhibitor on paper has the phenomenon that is penetrated into below paper, oxidation inhibitor is met water in printing process failure phenomenon, and existing anti-siccative all can't address the above problem at present.
By retrieval, find following three pieces of patent documents:
1, the special-purpose antiskinning agent (CN1702122) of offset press ink fountain and ink spreader, on ink fountain that can be in water offset press or dry offset press and the ink roller of ink spreader, apply, this antiskinning agent is containing polyfunctional solvent ethanol 66-68%, TX-10 tensio-active agent 1.2-1.4%, Resorcinol 1.8-2.0%, methyl carbitol 21-23%, 210 Dormant oils 8-10%.
2, antiskinning agent (CN1961036), component (a) is the oxygen scavenqer of organic or inorganic, component (b) is alkylamine and/or alkyl alkanolamine, also relate to the composition containing this combination, especially the paint of oxidation drying or coating composition, and be coated with the paint of this oxidation drying or the goods of coating composition.
3, a kind of production method of anti-skinning agent MEKO (CN101759595A), at first take SiO2, TiO2, TPAoHIPA, H2O has synthesized the catalysts titanium-silicon molecular sieve TS-1 as raw material adopts hydrothermal method, then catalysts titanium-silicon molecular sieve TS-1 powder and solvent are added in three mouthfuls of jacketed glass reactor with the condensing reflux pipe, the water bath with thermostatic control heating, magnetic agitation, add methylethylketone when being warming up to preset temperature, drip continuously ammoniacal liquor and H2O2 solution, add rear continuation reaction 1h, obtain the finished product methyl ethyl ketoxime.
Through technical comparison, above-mentioned patent document has the different of essence from present patent application.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, anti-siccative of a kind of environment-friendly type and preparation method thereof is provided, prepared anti-siccative safety and environmental protection, anti-oxidant efficiency is high, good with the printing ink intermiscibility.
For solving the problems of the technologies described above, the present invention adopts following technical proposal:
The anti-siccative of a kind of environment-friendly type, its raw material forms and the mass percent scope is respectively:
Antioxidant 2246: 15-20%
Food grade phenolic antioxidant: 10-15%
Dioctyl phthalate (DOP): 40-50%
High boiling point solvent oil: 20-30%.
And described food grade phenolic antioxidant comprises tertiarybutylhydroquinone.
And described high boiling point solvent oil comprises Octyl adipate.
The preparation method of the anti-siccative of a kind of environment-friendly type: dioctyl phthalate (DOP) is heated to 35-60 ℃, at keeping warm mode, slowly add tertiarybutylhydroquinone fully to stir until dissolve fully, add again Octyl adipate, when the temperature to 80 ℃-90 ℃, slowly add antioxidant 2246, fully stir until dissolving fully continues to stir 40-60 minute to guarantee that oxidation inhibitor is uniformly distributed in solvent, gets product under keeping warm mode.
Advantage of the present invention and positively effect are:
1, safety and environmental protection of the present invention, smell is low, good with the printing ink intermiscibility.
2, the anti-oxidant efficiency of the present invention is high, can effectively extend the printing ink can opening time and the residence time on printing press.
3, the present invention is liquid antioxidant, and its effective constituent is uniformly dispersed, and add-on is accurate.
4, the present invention can effectively stop yellow China ink to turn the problems such as green and blue black color change rust, water-soluble hardly, therefore ink-water balance is not had to negative impact.
5, the present invention by printing process with the speed that has improved conjunctival xerosis after water contacts, i.e. quick-drying on slow curing, paper on machine.
