Example Embodiment

[0022] Example 1

[0023] An ink for food packaging materials, in terms of weight fraction, including 20 parts of water-based acrylic resin, 20 parts of polyurethane emulsion, 10 parts of calcium carbonate, 5 parts of edible ethanol, 2 parts of defoamer, 30 parts of deionized water, and 5 parts of food coloring Copies.

[0024] The production method includes the following steps:

[0025] Weigh 20 parts of acrylic resin, 20 parts of polyurethane emulsion, 5 parts of edible ethanol, 10 parts of calcium carbonate, 2 parts of defoaming agent, 5 parts of food coloring and 30 parts of deionized water according to the ratio, and use a magnetic stirrer or electric stirrer to high speed Stir for 15 minutes to obtain pre-dispersion;

[0026] Pour the pre-dispersed liquid into a fast sand mill, add medium-sized zirconium beads, and sand at a rotation speed of 2000 r / min, during which the particle size is tested until the particle size distribution is stable, and a sample is obtained.

Abstract

The invention provides ink for food packaging materials and a preparation method and application of the ink. The ink is prepared from, in parts by weight, 20-30 parts of water-based acrylic resin, 20-30 parts of polyurethane emulsion, 10-15 parts of calcium carbonate, 5-10 parts of edible alcohol, 1-5 parts of defoamer, 30-40 parts of deionized water and 2-8 parts of food colorant. The water-basedacrylic resin is adopted as a connecting material, and due to low solid content in the ink, the ink has good dispersibility for the food colorant and good coloring polarity on OPP polypropylene plastic film, so that an ink layer has good printing adhesion, and printing is clear, does not fall off easily, and is resistant to hot water of 80 DEG C; in addition, environmental protection of the ink is achieved by adopting the deionized water; bubbles generated by grinding and stirring during preparation of pigment can be eliminated through the defoamer, so that even film of the ink is uniformly formed on packages, and the appearance of the formed film is good.

Description

technical field [0001] The application relates to the technical field of food packaging, and relates to an ink for food packaging materials and a preparation method and application thereof. Background technique [0002] Modern people are faced with greater work pressure and a fast pace of life. Convenience food has become a food that has to be chosen in life. For example, instant noodles, biscuits, etc., most of the food packaging is plastic film. It is necessary to print the product name, trademark brand, product source, composition, shelf life and other words and patterns on these plastic packages, and the colors are bright, especially the golden pattern. In addition to copper or zinc accounting for 60-80% in traditional inks, it also contains other Heavy metals seriously pollute the environment. [0003] The plastic film mainly includes an outer layer, an ink layer, an adhesive layer and an inner layer. The outer layer is a layer of OPP polypropylene (Orientpolypropyle...
