Aqueous diphenyl-ethylene paper cup flexographic printing ink and preparation method thereof

Abstract

The invention discloses an aqueous diphenylethylene paper cup flexographic printing ink. The components and the preparation method include that firstly, 30-40 percent of styrene and acrylic resin alkali-soluble resin, 15-20 percent of water, 10-25 percent of organic pigment,0.2-0.5 percent of silane defoamer, 0.1-0.3 percent of aqueous chloride / methylisothiazolinone mixture preservative, and 0.3-0.6 percent of silicone dispersant are mixed together; then, the mixture A is ground to a mixture with 5-10mum of fineness by a sand grinding machine; then, 30-40 percent of styrene-acrylic acid copolymer film-forming semi-self-crosslinking emulsion,5-10 percent of non film-forming rigid styrene-acrylic acid copolymer emulsion, 2-4 percent polytetrafluoro ethylene (PTFE) wax, 0.3-0.8 percent of fluorocarbon organic silicone leveling agent, 0.2-0.5 percent of silicone oil, 0.2-0.5 percent of ethanolamine, 1-3 percent of propylene glycol are added into the mixture and fully and evenly stirred; finally, the product is prepared. The product has good adhesion, abrasion resistance and frost resistance, has acid-proof, alkali-proof, water-proof, temperature-proof and light-proof characteristics, and also has no toxicity, so the product has a very broad application prospect.

Description

technical field

[0001] The invention relates to the field of printing inks, in particular to a water-based diphenylethylene (DPE) paper cup flexographic ink and a preparation method thereof. Background technique

[0002] With the improvement of people's living standards, higher requirements have been put forward for food packaging, and ink has attracted special attention in packaging. As a printing material, ink should meet various functional requirements, such as non-toxic, heat-resistant, cold-resistant, solvent-resistant, oil-resistant, friction-resistant, etc. It is internationally recognized that inks used in food printing must comply with the principle of no transfer; conventional inks are not allowed to be used for printing on the inner surface of food packaging; printing manufacturers must ensure that all solvents in the ink evaporate after printing and meet the corresponding standards of the application industry, and paper cups belong to food packaging.
