Abstract

The invention belongs to the field of chemical coatings and particularly relates to water-soluble silk-screen printing ink and a preparation method thereof. The water-soluble silk-screen printing ink is mainly prepared from waterborne polyurethane resin, waterborne acrylic resin, white paste, a crosslinking agent, a leveling agent, tripropylene glycol ether and a thickener, wherein the white paste is mainly prepared from titanium dioxide, a dispersant, a wetting agent, an antifoaming agent and deionized water, and the particle size of the white paste is 3-4 mu m. A formula of the water-soluble silk-screen printing ink is reasonably and scientifically matched, all components cooperate to enhance adhesion, coloring rate, flexibility, sweat resistance and corrosion resistance of a water-soluble silk-screen printing ink coating, a printed product painted with the coating has the effects that the printed product has transparent and bright surface, is glossy and do not fade or peel off after long-term usage, and the water-soluble silk-screen printing ink has low content of VOCs (volatile organic compounds) and heavy metals, is healthy and environment-friendly and meets the requirements of modern people.

Description

technical field [0001] The invention belongs to the field of chemical coatings, and in particular relates to a water-soluble screen printing ink and a preparation method thereof. Background technique [0002] Printing ink is a fine chemical product that transmits information and decorates the cultural world. Screen printing ink refers to all inks that use screen printing. With the prosperity of the country's economy, the development of culture, education and printing industry, the ink industry and printing industry have also achieved rapid development. In recent years, in order to protect the environment, many countries have increased many hygiene and environmental protection requirements and constraints in packaging and printing, especially for food packaging and printing. Since solvent-based inks contain a large amount of volatile toxic solvents, water-based inks have gradually replaced their use in the packaging industry. [0003] The binder is the key component of wate...
