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 takes place in printing ink and coating easily.In order to address this problem, will add anti-siccative usually, but the anti-oxidant efficient of existing anti-siccative is lower, its proterties is lotion or solid mostly, and is relatively poor with the intermiscibility of printing ink; Simultaneously, some iron ions are always arranged in the printing ink, oxidation inhibitor is coupling reaction when running into iron ion, and colour-change is very dark.Especially existing phenols anti, bigger to the influence of the dryness of coating, like the improper slightly not conjunctiva that will make after the coating brushing in several days of consumption, be prone to yellowing in addition, and be brown with the iron ion reaction, have some pungent tastes in addition.
The oxidation inhibitor solvability is divided into fully dissolves, is partly dissolved, does not dissolve fully.The good antioxidant effect of generalized case and printing ink dissolved is good; Another kind of phenomenon is exactly a compatibility, two kinds or above material mixing, and the general antioxidant effect that compatibility is good is good.The height of antioxygen efficient is to have the chemical structure of oxidation inhibitor to determine, but the efficient of in different printing ink, reacting with a kind of oxidation inhibitor is different, thus to find out the oxidation inhibitor that matches relatively through overtesting, so that reach best effect.
Flexographic ink is in press hoped slow curing on machine, to paper, does soon.Hoping has three kinds of modes to offset the effect of oxidation inhibitor: oxidation inhibitor has volatilization phenomenon, printing ink to print to that oxidation inhibitor on the paper has the phenomenon that is penetrated into below the paper, oxidation inhibitor is met water in printing process has failure phenomenon in printing process, and existing anti-siccative all can't address the above problem at present.
Through retrieval, find following three pieces of publication documents:
1, the special-purpose anti (CN1702122) of offset press ink fountain and ink spreader; Can on the ink roller of ink fountain in water offset press or the dry offset press and ink spreader, use; This anti contains 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, anti (CN1961036); Component (a) is the oxygen scavenqer of organic or inorganic; Component (b) is alkylamine and/or alkyl alkanolamine; Also relate to the compsn that contains this combination, the especially lacquer of oxidation drying or coating composition, and be coated with the lacquer of this oxidation drying or the goods of coating composition.
3, a kind of working method of anti methyl ethyl ketoxime (CN101759595A); Be that raw material adopts hydrothermal method to synthesize the catalysts titanium-silicon molecular sieve TS-1 at first with SiO2, TiO2, TPAoHIPA, H2O; Then catalysts titanium-silicon molecular sieve TS-1 powder and solvent adding are had in three mouthfuls of jacketed glass reactor of condensing reflux pipe water bath with thermostatic control heating, magnetic agitation; Add methylethylketone when waiting to be warming up to preset temperature; Dropping ammonia and H2O2 solution add continued reaction 1h continuously, promptly obtain the finished product methyl ethyl ketoxime.
Through the technology contrast, above-mentioned publication document has the different of essence with present patent application.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, anti-siccative of a kind of environment-friendly type and preparation method thereof is provided, prepared anti-siccative safety and environmental protection, anti-oxidant efficient is high, and is 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 constitutes and the mass percent scope is respectively:
Antioxidant 2246: 15-20%
Food grade phenolic antioxidant: 10-15%
DOP: 40-50%
High boiling point solvent oil: 20-30%.
And said food grade phenolic antioxidant comprises tertiarybutylhydroquinone.
And said high boiling point solvent oil comprises Octyl adipate.
The preparation method of the anti-siccative of a kind of environment-friendly type: DOP is heated to 35-60 ℃; Slowly add tertiarybutylhydroquinone at keeping warm mode and fully stir, add Octyl adipate again, treat temperature to 80 ℃-90 ℃ until dissolving fully; Slowly add antioxidant 2246; Fully stir until dissolving fully, under keeping warm mode, continue to stir 40-60 minute, get product to guarantee oxidation inhibitor uniform distribution in solvent.
Advantage of the present invention and positively effect are:
1, safety and environmental protection of the present invention, smell is low, and is good with the printing ink intermiscibility.
2, the anti-oxidant efficient of the present invention is high, can prolong effectively that printing ink is opened jar time and the residence time on printing press.
3, the present invention is a 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 problems such as green and blue black color change rust, and is water-soluble hardly, therefore ink-water balance do not had negative impact.
5, the present invention promptly does on slow curing, the paper on the machine through having improved conjunctiva exsiccant speed in the printing process with after water contacts soon.
Embodiment
Below in conjunction with embodiment, the present invention is further specified, following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
