Problems solved by technology
It is hoped that there are three ways to counteract the effect of antioxidants: during the printing process, the antioxidants will volatilize, when the ink is printed on the paper, the antioxidants will penetrate under the paper, and when the printing process encounters water, the antioxidants will fail phenomenon, the existing anti-drying agent can not solve the above problems

preparation example Construction
[0032] A preparation method of an environment-friendly anti-drying agent, the steps are (taking 100 kg of finished product as an example):
[0033] Heat 46 kg of dioctyl phthalate to 45 ° C, slowly add 12 kg of tert-butyl hydroquinone in the heat preservation state, and stir fully until it is completely dissolved, then add 24 kg of dioctyl adipate, wait until the temperature To 85°C, slowly add 224618 kg of antioxidant, stir until it is completely dissolved, and continue stirring for 50 minutes under heat preservation to ensure that the antioxidant is evenly distributed in the solvent, and 100 kg of finished anti-drying agent is obtained.
[0034] During the above stirring process, the speed should not be too fast, so as not to infiltrate too much air and generate air bubbles.
Embodiment 2
[0036] An environment-friendly anti-desiccant, its raw material composition and mass percentage are respectively:
[0037] Antioxidant 2246: 20%
[0038] tert-butylhydroquinone: 14%
[0039] Dioctyl phthalate: 42%
[0040] Dioctyl adipate (DOA): 24%.
[0041] A preparation method of an environment-friendly anti-drying agent, the steps are (taking 100 kg of finished product as an example):
[0042] Heat 42 kg of dioctyl phthalate to 35-60 ° C, slowly add 14 kg of tert-butyl hydroquinone in the heat preservation state and stir until it is completely dissolved, then add 24 kg of dioctyl adipate, wait until the temperature To 80°C, slowly add 224,620 kg of antioxidant, fully stir until completely dissolved, and continue stirring for 60 minutes in the heat preservation state to ensure that the antioxidant is evenly distributed in the solvent, and 100 kg of finished anti-drying agent is obtained.

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 [0001] The invention belongs to the field of ink and paint, and relates to an anti-drying agent, in particular to an environment-friendly anti-drying agent and a preparation method thereof. Background technique [0002] At present, inks and coatings are prone to curing and skinning during use. In order to solve this problem, an anti-drying agent is usually added, but the anti-oxidation efficiency of the existing anti-drying agent is low, and its properties are mostly paste or solid, and the compatibility with the ink is poor; at the same time, there is always some iron in the ink Ions, antioxidants develop a color reaction when encountering iron ions, and the color changes deeply. Especially the existing phenolic anti-skinning agents have a great influence on the dryness of the paint. If the amount is not suitable, the paint will not have conjunctiva within a few days after brushing, and it is easy to turn yellow and react with iron ions. Brown, and also ha...
