Abstract

The invention discloses fluorine-silicon-epoxy-modified aqueous acrylate emulsion ink special for a PVC film and a preparation method of the ink. The ink consists of the following raw materials in parts by weight: 1-5% of a film forming additive, 0.5-3% of a surfactant, 0.5-3% of a drier, 0.5-3% of a leveling agent, 1-5% of a crosslinking agent, 15-20% of aqueous color paste, 50-60% of a fluorine-silicon-epoxy-modified aqueous acrylate emulsion and 20-30% of water. The fluorine-silicon-epoxy-modified aqueous acrylate emulsion ink takes the water as a solvent, so that the ink has no volatile odor; when the ink is applied to the PVC film, the wettability is good; an ink coating film with the thickness of 50 um can reach a surface drying state within 6 seconds at 50 DEG C, and the adhesion fastness reaches 99%; the ink can be scrubbed by 70% of an ethanol aqueous solution more than 100 times after curing completely, and the adhesion resistance reaches 95%; and the preparation process is simple, the production cost is low, and the ink is favorable for universal popularization and application.

Description

Technical field [0001] The invention relates to a printing ink, in particular to a fluorine-silicon-epoxy modified waterborne acrylic emulsion ink for PVC film and a preparation method thereof. Background technique [0002] One of the development directions of printing inks in the 21st century is environmentally friendly inks, that is, low-pollution or non-pollution inks: including high-solid and solvent-free inks, water-based inks, powder inks and radiation (such as UV, EB) inks four types. In recent years, as environmental pollution has intensified and people’s awareness of environmental protection has increased, solvent-based inks are facing severe challenges. At the same time, newly established laws and regulations have higher and higher requirements for solvent-based inks. Under this opportunity, water-based inks Obtained huge room for development. [0003] Due to its relatively low cost, high mechanical strength, high and low temperature resistance, aging resistance and corr...
