Abstract

The invention provides a method for preparing rosin glycerol modified polyurethane resin for ink. The method comprises the following steps: adding 100 parts by weight of poly(1,4-butylene adipate), 15-25 parts by weight of isophorone diisocyanate and 1-3 parts by weight of dibutyltin dilaurate into a reactor, and carrying a reaction at 80-90 DEG C for 1-2 h; and adding 10-20 parts of rosin glycerol ester polyol, carrying out a reaction at 70-90 DEG C for 1-2 h, cooling the obtained reaction product to 30-40 DEG C, adding 0.2-1.2 parts of tetraethyl-D-glucono-1,6-lactone and 0.1-1 part of (E)-1-Heptene-1,2-diboronic acid bis(pinacol) ester, and carrying out a reaction for 4-6 h to obtain the rosin glycerol modified polyurethane resin.

Description

technical field [0001] The invention relates to a preparation method of ink additives, in particular to a preparation method of rosin glycerin-modified polyurethane resin for ink. Background technique [0002] With the development of China's economy and cultural undertakings, the printing, publishing and packaging industries are developing rapidly. The domestic demand for ink has increased dramatically. Due to the enhancement of people's awareness of environmental protection and the improvement of people's safety requirements for food packaging and printing, it is required to reduce the proportion of toxic and volatile organic components of aromatic hydrocarbons in the ink composition. Environmentally friendly inks have gradually experienced benzene-free inks, alcohol-soluble inks and water-based inks, and Gradually replace traditional volatile organic solvent-based inks. Polyurethane ink has gradually developed rapidly due to its unique performance advantages. It has the ...
