Problems solved by technology

The coating-free double PE water-based flexographic ink disclosed in this document has the characteristics of high gloss, waterproof, abrasion resistance, and freezing resistance. However, this ink is only suitable for double PE cup printing, and the drying speed is slow when printing Tyvek. Poor resolvability and easy paste problem
Chinese patent, application number: 200610062147.9 invention patent document, discloses a water-based flexographic printing ink and its preparation method, which includes film-forming resin emulsion 8.7-47.2%, water-based acrylic color paste 40-50%, defoaming 0.1-0.3% of solvent, 0.2-2.0% of water-based wax slurry, 2-8% of isopropanol, 10-30% of ethylene glycol, 0.5-1% of ethanolamine, and the balance is water; the water-based flexographic printing ink disclosed in this document It has the advantages of clear imprint and low production cost; this ink has good adaptability to coated paper printing, but it has poor adhesion and easy decolorization when it is used on materials with low surface tension and low penetration like Tyvek
[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention is suitable for the technical field of printing material preparation, and provides a Tyvek water-based flexographic printing material. The Tyvek water-based flexographic printing material comprises the following raw material components in percentage by weight of 55-65% of a diluent which comprises the following raw material components in percentage by weight of 60-80% of polyurethane resin, 0-35% of acrylic resin, 1-5% of an adhesion promoter, 1-4% of a wear-resistant agent, 0-1% of a wetting agent, 0-8% of a stabilizing agent, 0.1-0.5% of a defoaming agent, 30-40% of deionized water, and 35-45% of water-based color paste. Therefore, when a flexographic printing machine is used for printing a Tyvek material, the printing material has the characteristics of clear printed patterns, good adhesive force, high drying speed, low odor and capability of meeting the latest environmental protection requirement, and can completely replace the existing high-VOC solvent type printing ink.

Description

technical field [0001] The invention relates to the technical field of printing material preparation, in particular to a Tyvek water-based flexographic printing material and a preparation method thereof. Background technique [0002] Tyvek is a unique non-woven product introduced in recent years. It is a spun-bonded olefin made of countless fine polyethylene fibers. This unique spray-spinning technology can produce light-weight, reflective High rate yet very tough material. This material has the characteristics of not easily deformed, soft and smooth, light and tough, excellent opacity, moisture resistance, and water stain resistance, and is widely used in the medical packaging and food packaging industries. However, because it is made of polyethylene material, there is a problem that the surface of the material is inert and it is not suitable for easy printing. At present, the printing industry mostly uses high-VOC solvent-based ink printing to solve the problem of easy de...
