Embodiment 1

[0029] A water-based diphenylethylene paper cup flexographic ink; including 30% styrene-acrylic acid copolymerized film-forming semi-self-crosslinking emulsion, 10% styrene acrylic resin alkali-soluble resin, 5% non-film-forming Rigid styrene-acrylic copolymer emulsion, 0.3% silicone dispersant, 0.2% silane defoamer, 0.2% silicone oil, 0.2% MEA, 1% propylene glycol, 0.1% aqueous chloromethyl / methylisothiazolinone (CMI / MI) mixture preservative, 2% polytetrafluoroethylene wax, 0.3% fluorocarbon silicone leveling agent, 15% organic pigment, 15% water.

[0030] Preparation method: first mix the above-mentioned amount of styrene acrylic resin alkali-soluble resin, water, organic pigment, silane defoamer, water-based chloromethyl / methylisothiazolinone (CMI / MI) mixture preservative, silicone Mix the dispersant to obtain mixture A; then use a sand mill to grind mixture A to a mixture powder B with a fineness of 10 μm, and then add styrene-acrylic acid copolymerized film-forming semi-...

Embodiment 2

[0032] A water-based diphenylethylene paper cup flexographic ink; including 35% styrene-acrylic acid copolymerized film-forming semi-self-crosslinking emulsion, 15% styrene acrylic resin alkali-soluble resin, 10% non-film-forming Rigid styrene-acrylic copolymer emulsion, 0.4% silicone dispersant polyoxyethylene ether, 0.3% silane defoamer emulsified silicone oil, 0.3% silicone oil, 0.3% MEA, 1% propylene glycol, 0.2% aqueous chloromethyl / methyl Isothiazolinone (CMI / MI) mixture preservative, 3% polytetrafluoroethylene wax, 0.5% fluorocarbon silicone leveling agent, 20% organic pigment, 17% water.

[0033] The preparation method is the same as in Example 1, the difference is that the fineness of the mixture powder B is 6 μm, the water resistance is slightly improved, a little decolorization after washing, the adhesion reaches level 4, the slipperiness is slightly improved, and the slip angle reaches 20 degrees. Abrasion resistance is slightly improved, can wear 2lb, 100 times. ...

Embodiment 3

[0035] A water-based diphenylethylene paper cup flexographic ink; including 40% styrene-acrylic acid copolymerized film-forming semi-self-crosslinking emulsion, 15% styrene acrylic resin alkali-soluble resin, 8% non-film-forming Rigid styrene-acrylic copolymer emulsion, 0.6% silicone dispersant polyoxyethylene ether, 0.5% silane defoamer emulsified silicone oil, 0.5% silicone oil, 0.5% MEA, 3% propylene glycol, 0.3% aqueous chloromethyl / methyl Isothiazolinone (CMI / MI) mixture preservative, 4% polytetrafluoroethylene wax, 0.8% fluorocarbon silicone leveling agent, 25% organic pigment, 20% water.

[0036] The preparation method is the same as in Example 1, the difference is that the fineness of the mixture powder B reaches 5 μm, the best water resistance, no decolorization after washing, excellent adhesion can reach level 5, full color, strong transferability, smoothness Improvement, the slip angle reaches 15 degrees, and the abrasion resistance is improved, which can wear 2lb, ...

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. A type of p...
