Abstract

The invention provides water-based inner printing ink coated with PE and PP and a preparation method thereof. The water-based inner printing ink coated with the PE and the PP contains, by weight, 25-30 parts of varnish, 65-75 parts of water-based color paste and 0.1-0.3 part of defoaming agent, wherein the varnish contains, by weight, 50-70 parts of styrene-acrylate non-film-forming emulsion, 20-35 parts of acrylic resin solution or styrene-maleic anhydride resin solution, 1-3 parts of wax emulsion, 3-8 parts of coalescing agent, 0.1-0.5 part of organic amine, 0.5-1 part of wetting agent, 0.1-0.3 part of defoaming agent and 0.05-0.15 part of preservative, and the Tg value of the styrene-acrylate non-film-forming emulsion is greater than or equal to 85 DEG C. The water-based color paste contains, by weight, 20-25 parts of acrylic resin solution, 1-2 parts of wetting dispersant agent, 25-35 parts of deionized water, 40-45 parts of pigment, 0.1-0.3 part of defoaming agent and 0.05-0.15 part of preservative. The water-based inner printing ink is resistant to high temperature and abrasion, is small in chromatic aberration after being coated with PE and PP films, is high in peel strength on a basic material and can well meet the requirement of a spraying process.

Description

Technical field [0001] The invention relates to a water-based ink, in particular to a water-based PE and PP water-based lining ink for curtain coating and a preparation method thereof. Background technique [0002] Ink is an essential material for decoration and packaging of printed goods. In recent years, with the rapid development of the printing industry, packaging and printing of various plastics and paper industries have continued to improve. The composite flexible package is composed of two or more composite films. The outer layer is usually a decorative layer with patterns printed inside, and the inner layer can be a gas barrier layer, a light-shielding layer, a heat-sealing layer, etc. Due to its unique characteristics, composite flexible packaging has been widely used in the packaging of various commodities such as food, medicine, tea, beverages, alcohol, dairy products, aquatic products, and military products. [0003] Laminating is to coat a layer of polyethylene (PE) ...
