A method used for preparing the environment-friendly composition comprises the steps: (1) 10-30 parts of the food grade antioxidant and 70-90 parts of the vegetable oil are weighed; the butylhydroxyanisol and the 2, 6-ditert-butyl paracresol or the 2, 6-ditert-butyl paracresol are adopted as the antioxidant; and the coconut oil, the flax seed oil, the soybean oil, the colza oil or the peanut oil can be selected as the vegetable oil; (2) the vegetable oil is added into a reaction kettle according to the mixture ratio, and then heated up and stirred; when the temperature raises above 60 DEG C, the antioxidant is added into the reaction kettle according to the mixture ratio to be stirred and heated up to 90-110 DEG C; the temperature is preserved for 30-40min, and the test viscosity is 5-50 mpas/25 DEG C. The invention has simple technique and remarkable effect.
Description
Technical field
The present invention relates to a kind of composition and method of making the same that prevents printing ink oxidization, particularly a kind of environment-friendly composition that prevents printing ink oxidization and preparation method thereof.
Background technology
Flexographic ink can be divided into offset printing sheet-fed printing ink and offset rotary ink, and these printing ink all need the printing ink slow curing when depositing and printing with machine in packing box, is printed on that the back is fast on the paper does.This just need add the antioxygen auxiliary agent and delay the printing ink conjunctiva in printing ink.At present, the auxiliary agent that ink product on the market adopts is generally mineral oil solvent and aromatic amine antioxidant, and application method is directly to transfer in printing ink or make sprays to be sprayed on above the printing ink in printing press ink fountain, the print cartridge.Because the solvent and the mineral oil that adopt mostly are toxic substance or aromatic hydrocarbon substance, such antioxygen auxiliary agent not only can printing product and air cause certain pollution, more can directly endanger the healthy of operator.
Therefore, providing a kind of environment-friendly composition that prevents printing ink oxidization and preparation method thereof, is one of the current urgency of this field scientific research personnel difficult problem to be solved.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, a kind of effective raising ink quality is provided, technology is simple, and obvious results prevents environment-friendly composition of printing ink oxidization and preparation method thereof.
Implementation step of the present invention for achieving the above object is as follows:
A kind of environment-friendly composition that prevents printing ink oxidization is characterized in that being prepared from by the composition of following portions by weight proportioning is mixing: 10～30 parts of food grade antioxidants, 70～90 parts of vegetables oil.
Described food grade antioxidants adopts butyl hydroxy anisol and 2,6-ditertbutylparacresol, or select 2 for use, the 6-ditertbutylparacresol.
Described vegetables oil is selected Oleum Cocois, oleum lini, soybean oil, rapeseed oil or peanut oil for use.
A kind of preparation method who prevents the environment-friendly composition of printing ink oxidization is characterized in that implementation step is as follows:
(1) takes by weighing 10～30 parts of food grade antioxidants, 70～90 parts of vegetables oil; Described antioxidant adopts butyl hydroxy anisol and 2,6-ditertbutylparacresol, or select 2 for use, the 6-ditertbutylparacresol; Described vegetables oil is selected Oleum Cocois, oleum lini, soybean oil, rapeseed oil or peanut oil for use; It can be through the industrial treatment product that the vegetables oil that adopts is made solvent; Float isolating protein as essence.
(2) vegetables oil is added in the reactor by proportioning, heat up and stir, when temperature rises to more than 60 ℃, add antioxidant by proportioning, stir and be warming up to 90～110 ℃, be incubated 30～40 minutes, 5～50mpas/25 ℃ of check viscosity is up to the standards at last routinely, filters, packs.
The invention has the beneficial effects as follows: therefore the present invention has not only eliminated the organic compound of volatile, and has made its contactless property toxicity owing to do not adopt organic solvent and the mineral oil and the aromatic amine antioxidant that contain aromatic hydrocarbons.This product has fine anti-oxidant, the special efficacy that suppresses the printing ink conjunctiva, so add-on can significantly reduce in printing ink.This product uses crude vegetal and food grade antioxidants, eliminated the toxicity of volatile organic compound, reduced pollution greatly, effectively ensured operator's health printing product and air, this auxiliary agent does not have any injury to human body, is superior safety and environmental protection product.The scope of application is very extensive, said composition can directly add in the flexographic ink (single-sheet offset printing ink, news glue rotary printing, thermosetting offset rotary ink) can effectively prevent printing ink in packing with printing press on conjunctiva.This auxiliary agent can also be made into sprays, is sprayed at ink pellet surface, makes it delay the conjunctiva time.Said composition has and suppresses conjunctiva effect, safety and environmental protection efficiently; Its technology is simple, and effect is remarkable, can effectively improve the quality of ink product.
