[0029] 2. Add 26.7g of dehydrated hydroxypropyl acrylate, 14.8g of acrylic acid, and 18.0g of methyl methacrylate into a four-necked flask. The temperature is raised to 62℃, and 4.9g of azobisisobutyronitrile (AIBN After the dripping is completed, the reaction is continued for 2.5 hours, and 8.7g of dimethylolpropionic acid (DMPA) after dehydration and 102.5g of polyester diol (molecular weight 500) are added and reacted for 1.5 hours;

[0030] 3. The temperature is raised to 85°C, nitrogen is introduced, and 37.8 g of tetramethyl dimethyl diisocyanate (TMXDI) mixed with two drops of dibutyl tin dilaurate (DBT) (TMXDI) are added dropwise. After the addition is complete, continue the reaction For 2.5 hours, add a small amount of acetone to adjust the system viscosity, and measure the -NCO group every 30 minutes. When the -NCO group does...

Embodiment 2

Abstract

The invention provides alcohol aqueous gravure plastic composite printing ink. The alcohol aqueous gravure plastic composite printing ink comprises the following components in parts by mass: 35 to 48parts of polyurethane modified acrylic acid emulsion, 0.5 to 2 parts of a macromolecular type dispersing agent, 0.2 to 1 part of water-based polyethylene wax, 0.5 to 1 part of fumed silica, 10 to 38 parts of pigment powder, 0.5 to 2 parts of triethanolamine, 12 to 29 parts of ethanol and 4.9 to 20 parts of deionized water. End sealing is conducted by utilizing organic amine with a low boiling point, the organic amine with the low boiling point is introduced, the amine with the low boiling point is volatized slowly at normal temperature, a large amount of hydrophilic groups still exist in resin, and high dissolubility is achieved in an alcohol water system; when the resin is prepared into the printing ink and passes through a drying oven, escape of the amine with low boiling point on the resin is accelerated, so that the resin hydrophilic groups are greatly reduced, volatilization of water is accelerated, the printing ink is water-resistant after being dried, the printing ink on a printing plate is still at normal temperature, a large amount of hydrophilic groups still exist, high re-dissolubility is still achieved within a period of time and the printing use requirement is met.

Description

Technical field [0001] The invention relates to a resin of an alcohol-water gravure plastic composite ink and a method for preparing the ink, belonging to the technical field of inks. Background technique [0002] With the improvement of human living standards, people’s needs for packaging are becoming more and more diversified, refined, quality and environmentally friendly. Accompanying it is that people have higher requirements for inks that give packaging fresh vitality— -"Green Ink". [0003] From October 1, 2015, the "Volatile Organic Compounds Pollutant Discharge Pilot Measures" was officially implemented, and the packaging and printing industry was among them; from January 1, 2016, the "People's Republic of China Air Pollution Prevention and Control Law" (revised edition) was officially implemented , Volatile organic compounds (VOCs) emissions and governance are included in the supervision. As of the end of last year, Beijing, Shanghai, Jiangsu, Anhui, Hunan, Sichuan, Tian...
