Abstract

The invention relates to the field of printing, and concretely relates to a water-based ink suitable for PVC film printing, and a preparation method thereof. The water-based ink comprises, by mass, 50-55 parts of a water-based acrylic resin emulsion, 28-33 parts of deionized water, 1-2 parts of a defoaming agent, 10-13 parts of a pigment, 1-3 parts of a film-forming agent, 1-2 parts of a surfactant, 1-10 parts of an adhesion promoter, and 1-3 parts of modified montmorillonite. The ink is excellent in adhesive force and high in surface drying speed, and meets the requirements of the printing PVC industry for low-temperature quick drying, adhesive force and alcohol resistance of a printing PVC printing ink coating.

Description

technical field [0001] The invention relates to the field of printing, in particular to a water-based ink suitable for PVC film printing and a preparation method thereof. Background technique [0002] At present, lithographic printing is one of the main printing methods in my country. The printing inks used are mainly solvent-based inks. Toxic and harmful solvents must be used in the production of such inks, resulting in direct emissions of hundreds of thousands of VOC (volatile organic compounds) every year. tons, causing serious environmental pollution. One of the development directions of printing inks in the 21st century is environmentally friendly inks, that is, low-pollution or non-polluting inks: including four types of high-solid and solvent-free inks, water-based inks, powder inks and radiation (such as UV, EB) inks. In recent years, with the intensification of environmental pollution and the enhancement of people's awareness of environmental protection, solvent-bas...
