Based on percentage by weight, the preparation method comprises the following steps: A, adding 30-35% of rosin resin into a reaction kettle; heating to 130-140 DEG C so as to melt the rosin resin; stirring, adding 6-10% of maleic anhydride and heating to 180 DEG C; insulating for 1-1.5 hours; then, adding 0.02-0.04% of zinc oxide and 1-5% of pentaerythritol; insulating for 0.5-1 hour and adding 6-10% of tung oil; insulating for 0.5-1 hour; B, cooling to 140 DEG C, adding 3% of xylene based on the total weight to reflux, heating to 180 DEG C, insulating for 0.5-1 hour, quickly heating to 270-275 DEG C, and insulating for 0.5-1 hour; C, cooling to 160 DEG C, and dropwise adding 1-5% of cholamine and 1-5% of butyl acetate; during dropwise adding, cooling from 160 DEG C to 120 DEG C, controlling the dropwise adding time within 1-1.5 hours; then, cooling to 80 DEG C and adding 8-12% of mixed alcohol; then, cooling to 60 DEG C and adding 10-15% of amine stabilizing liquid; insulating for 0.5-1 hour; finally, adding 15-25% of acetic ether, cooling to 40 DEG C and discharging.

Description

technical field [0001] The invention relates to the technical field of paint inks, in particular to a water-based ink resin and a preparation method. Background technique [0002] Existing printing inks mainly use water-soluble rosin resin as a color carrier, and are used to enhance the adhesion of ink to paper. Water-soluble rosin resin is made of refined rosin as the basic raw material through hydrogenation, esterification, stabilization and other processes. Good aging resistance and good compatibility with polymer materials. [0003] Water-soluble rosin resin has a large number of carboxyl groups or acid anhydride groups in its structure, and its pH value is low, which can easily cause the ink to coalesce and become moldy during storage and transportation, and change the viscosity of the ink, so it is necessary to add a pH value regulator during the preparation process Adjust pH. At present, additives such as ammonia water or ethanolamine are generally used as pH regul...
