Overprint varnish-free high wear resistance aluminum foil lined paper water-based ink and preparation method thereof

Abstract

This invention relates to the field of inks, and discloses an overprint varnish-free high wear resistance aluminum foil lined paper water-based ink. The overprint varnish-free high wear resistance aluminum foil lined paper water-based ink comprises 20-25 wt% of an aqueous acrylic film-forming emulsion or an aqueous styrene/acrylic emulsion or a polyurethane modified acrylic emulsion, 20-35 wt% ofan aqueous acrylic non-film forming emulsion, 2-25 wt% of an aqueous acrylic solution, 0.2-2 wt% of a wetting agent, 0.1-0.5 wt% of a defoamer, 0.4-0.6 wt% of a pH adjuster, 10-25 wt% of a color paste, 4-10 wt% of a wax paste, 4-10 wt% of a wear-resistant slurry, 5-15 wt% of water and 0.1-2 wt% of a film forming aid, wherein the wear-resistant slurry comprises 20-30 wt% of an aqueous acrylic solution, 20-25 wt% of water, 5-10 wt% of a water-modified modified polyethylene wax micro-powder, 1-2 wt% of an aqueous dispersion aid, 8-9 wt% of a cosolvent, 20-25 wt% of ultrafine kaolin and 10-15 wt%of ultrafine calcium carbonate. The ink has the adhesion of prime coating, also has the heatproof, waterproof, anti-slip, wear-resistant and scratch-resistant properties of a varnish, is convenient touse, and can simplify aluminum foil pre-coating, monochrome printing and three-time overprint varnish printing into one-time inking printing, so two printing processes are saved, and energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of inks, in particular to a varnish-free highly wear-resistant aluminum foil-lined paper water-based ink and a preparation method thereof. Background technique [0002] Generally, the process of printing products on aluminum foil or aluminum foil composite substrates is at least three processes, such as aluminum foil pre-coating, colored ink (ranging from 1 to 6 colors), and varnish. Pure aluminum foil for pharmaceutical packaging, my country usually uses aluminum foil special ink and varnish, and foreign countries usually use my country's pre-coated aluminum foil, and then print ordinary paper ink and varnish; food, tobacco and alcohol packaging use aluminum foil composite base Most of the composite substrates purchased by printing factories have already been primed by the substrate manufacturer, and the printing factory directly prints the pattern color and varnish. As the outermost protective layer of printed matte...

Problems solved by technology

[0003] In the application of traditional varnish, the pattern color printing process involves three steps of pre-coating, printing monochrome, and varnish. It is inconvenient to use, and the anti-skid effect is not ideal. Faults during processing
