Problems solved by technology

The reason is that domestic water-based resins cannot be diluted with ethanol, and the price of inks prepared from imported resins is about 30% to 50% higher than that of solvent-based inks. The price difference varies with different colors.

Abstract

The invention discloses self-crosslinking polyacrylate rubber latex, a preparation method thereof and water-based paper printing ink. The self-crosslinking polyacrylate rubber latex is prepared by the following steps: mixing an acrylic ester monomer, a hydrophilic monomer and ADH in a head tank A; mixing water, an emulsifier, the acrylic ester monomer and DAAM in a head tank B; adding water, the emulsifier and polymerizable self-emulsifying functional monomer, stirring the mixture, heating the mixture to 75 DEG C, and dripping a mixture in the head tank A and an initiator to prepare a protective colloid first; dripping the mixture in the head tank B and the initiator at 85 DEG C; and performing a constant-temperature reaction. The water-based paper printing ink is prepared by the following steps: dissolving a phenylethylene-acrylic acid polymer and a pH value regulator in water at 60 DEG C with stirring; adding a pigment and necessary assistant and mixing the mixture to prepare color paste; and uniformly mixing the color paste with the self-crosslinking polyacrylate rubber latex, a surface tension regulator and water. The water-based paper printing ink can be diluted by one or a mixture of two of water and ethanol, can be dried quickly and has high 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...
