Self-crosslinked polyacrylate latex and preparation method thereof, and water-based paper ink

Abstract

The invention discloses self-crosslinked polyacrylate latex and a preparation method thereof, and water-based paper ink. The preparation method for the self-crosslinked polyacrylate latex comprises the following steps of: mixing acrylate monomers, hydrophilic monomers and alcohol dehydrogenase (ADH) in a head tank A; mixing water, an emulsifier, acrylate monomers and diacetone acrylamide (DAAM) in a head tank B; adding water, an emulsifier and polymerization self-emulsification functional monomers into a normal-pressure reaction tank, stirring, heating to 75DEG C, dripping a mixture in the head tank A and an initiator, and preparing protective colloid; dripping a mixture in the head tank B and an initiator at 85DEG C; and reacting at constant temperature. The water-based paper ink is prepared by the following steps of: stirring and dissolving styrene-acrylate copolymer, a pH regulator and water at 60DEG C; adding pigments and necessary aids, and mixing to obtain color paste; and uniformly mixing the color paste, the self-crosslinked polyacrylate latex, a surface tension regulator and water. The water-based paper ink can be diluted by one of water and ethanol or a mixture of water and ethanol, and has high drying speed and good printing adaptability.

Description

technical field

[0001] The invention relates to a method for making water-based paper printing ink, in particular to a method for making self-crosslinking water-based paper printing ink that can be diluted with one or two mixtures of water and ethanol. Background technique

[0002] Gravure printing (referred to as gravure printing) is one of the main printing methods for high-grade paper (such as cigarette packs). With the improvement of printing substrates, equipment and processes, paper gravure printing inks are also constantly improving. Toluene solvents were used in the early 1990s, ester solvents were used in the late period, and alcohol ester solvent inks were used in this century. At present, high-end paper gravure printing inks such as cigarette labels, wine labels, and pictorials used in the market are based on alcohol ester solvents.

[0003] The biggest feature of water-based inks that use water as the main solvent is that the main solvent that volatilizes when t...
