preparation example Construction

[0042] see figure 1 , the present invention also provides the preparation method of above-mentioned printing ink, the preparation method of described food, pharmaceutical packaging water-based aluminum foil printing ink comprises the following steps:

[0043] Step A: material preparation and weighing;

[0044] The specific operation is: synthesizing or purchasing various raw materials specified above, and weighing them one by one according to the specified weight parts for future use.

[0045] Step B: Grinding to prepare color paste: Stir the water-based polyacrylic resin liquid, colorant, and dispersant in the container according to the formula amount, and then put it into an iron can for grinding, seal the iron can, put the iron can into a swing disperser or Disperse on a sand mill to prepare a spare color paste.

[0046] In the present invention, a certain amount of glass beads are added into the iron tank for ball milling or sand milling; the time for dispersing on a swi...

Embodiment 1

[0055]Weigh 15 parts of water-based acrylic resin solution with a solid content of 20% to 50%, 10 parts of white pigment, and 1 part of dispersant, add them to the container in turn and stir evenly, and then transfer to the iron for ball milling (or sand milling) treatment. Put a certain amount of glass beads (or steel balls) into the tank, seal the iron tank, put the iron tank into a swing disperser (or sand mill) and disperse for 2 to 3 hours, and wait until the fineness reaches below 15 μm, the standby color can be prepared. pulp.

[0056] Then add 42 parts of 25% to 60% propylbenzene emulsion, 15 parts of 30% to 58% water-based polyurethane-acrylate composite emulsion, 3 parts of water-based wax paste, 0.5 parts of leveling agent, 0.8 parts of slip agent, 5 parts of Add butyl ether, 2 parts of isopropanol and 2 parts of deionized water to the above-mentioned spare color paste, seal the tin can again, place it in a swing disperser (or sand mill) and continue to disperse for...

Embodiment 2

[0058] Weigh 30 parts of water-based acrylic resin solution with a solid content of 20% to 50%, 8 parts of black pigment, and 1.2 parts of dispersant, add them to the container in turn and stir evenly, and then transfer to the iron for ball milling (or sand milling) treatment. Put a certain amount of glass beads (or steel balls) into the tank, seal the iron tank, put the iron tank into a swing disperser (or sand mill) and disperse for 2 to 3 hours, and wait until the fineness reaches below 15 μm, the standby color can be prepared. pulp.

[0059] Then add 45 parts of 25% to 60% propylbenzene emulsion, 10 parts of 30% to 58% water-based polyurethane-acrylate composite emulsion, 2 parts of water-based wax slurry, 1 part of leveling agent, 0.5 part of slip agent, 2 parts of Add butyl ether, 4 parts of isopropanol and 3 parts of deionized water to the above-mentioned spare color paste, seal the tin can again, place it in a swing disperser (or sand mill) and continue to disperse for...

Abstract

The invention discloses hydrophilic ink for intaglio printing on surfaces of aluminum foils and a preparation method thereof. The hydrophilic ink for intaglio printing on the surfaces of the aluminum foils comprises the following raw materials: by weight, 15 to 30 parts of hydrophilic polyacrylic resin liquid containing 20% to 50% solid materials (solid content for short), 40 to 50 parts of propyl benzene emulsion with solid content 25% to 60%, 10 to 15 parts of hydrophilic polyurethane and acrylate ester composited emulsion with solid content 30% to 58%, 8 to 12 parts of colorant, 1 to 2 parts of dispersant, 0.5 to 1 part of slip agent, 0.5 to 1 part of flatting agent, 1 to 5 parts of hydrophilic wax syrup, 1 to 5 parts of butyl ether, 1 to 5 parts of isopropanol and 1 to 5 parts of deionized water. The hydrophilic ink is faster in drying speed, fine in adhesion, better in water resistance, moisture resistance and friction resistance, and better in after-tack property. Besides, the hydrophilic ink has fine film formation and color retention and better color development for pigments and also has high glossiness.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to a water-based ink used for gravure printing on the surface of aluminum foil and a preparation method thereof, in particular to an aluminum foil used for food and medicine packaging. technical background [0002] In recent years, aluminum foil has been widely used in food, medicine, aerospace and other fields due to its light weight, good airtightness, good wrapping property, and environmental protection. Since 2006, China's aluminum foil production capacity and output have continued to rank first in the world. The demand for aluminum foil market is growing rapidly. In 2008, China's aluminum foil output was 1.57 million tons, accounting for 44% of the world's total. At present, China's annual consumption of aluminum foil has become the world's second largest aluminum foil consumer after the United States. [0003] The food industry and the pharmaceutical industry are impor...
