Abstract

The invention discloses a washable paper product environment-friendly printing ink and a preparation method thereof. The printing ink comprises the following components (by weight percentage): 10-25 of modified rosin, 4-7 of a preservative, 30-45 of water, 1-1.5 of an anti-hard water agent, 1.5-1.8 of a diluent, 1-1.5% of an anti-sticking agent, 5-15% of ethanol, 25-35% of a pigment, and 0.5-1.5% of a defoaming agent. The preparation method includes: according to the formula amount, firstly putting the modified rosin into a reaction kettle, starting a blender, adding water, the preservative and the anti-hard water agent in order, raising the temperature of the reaction kettle to 70DEG C-80DEG C, performing stirring for 2h and controlling the heating temperature at 80DEG C+ / -2DEG C, at the end of stirring, conducting cooling to room temperature, adding the diluent, the anti-sticking agent and ethanol in proportion, further conducting stirring for 15min, depositing the mixture into a packaging barrel for standby use, adding the pigment into the base material according to the formula ratio, and conducting stirring for 30min, then adding the defoaming agent, and mixing the mixture evenly, thus obtaining the printing ink. The printing ink provided by the invention can realize double-component (color paste and base material) storage, can realize color matching when the ink is used, waste is avoided, the printed patterns have good water resistance and do not fade, and the price is very low.

Description

technical field [0001] The invention relates to the field of printing ink preparation, in particular to an environmentally friendly printing ink for water-resistant paper products and a production method thereof. Background technique [0002] At present, there are two main types of paper printing inks used in the market: Toppan water-based inks and Toppan alcohol-soluble inks. Toppan water-based ink uses ammonia as the resin modifier and water as the main solvent. Its main disadvantage is that the printed pattern is not washable and easy to decolorize. Toppan alcohol-soluble ink uses amine as the resin modifier and alcohol solvent as the main solvent, so it is expensive and toxic. The factory implements production. [0003] In the Chinese patent with the application number "201410093337.1", an invention patent named "a printing ink" is disclosed, and its technical scheme is as follows: including pigment 10-30%; active monomer 25-30%; %; photoinitiator 0.5%; curin...
