Ink

Abstract

The invention discloses an ink, which comprises the following components by weight: 35-45 parts of alcohol-soluble polyurethane resin, 45-50 parts of water-based polyurethane, 10-15 parts of butyl acetate, and 10-12 parts of propyl acetate , 5-15 parts of ethanol, 0.3-0.6 parts of defoamer, 2-3 parts of anti-settling agent, 1-2 parts of dispersant, 0.2-0.9 part of leveling agent, 0.3-0.8 part of antioxidant, 0.5-0.5 part of antistatic agent 1.2 parts, 20-35 parts of water, 15-25 parts of pigment, 15-25 parts of glycerin, 0.2-0.6 parts of matte powder, 1-5 parts of waterproofing agent and 0.3-0.5 parts of pine red plum essential oil; so the present invention is optimized Each component and dosage in the formula, the obtained printing ink is environmentally friendly, has strong coloring power, is not easy to fade, has high wear resistance, long service life, and the surface quality of the printed product is good.

Description

technical field [0001] The invention belongs to the technical field of inks, in particular to an ink with good water resistance. Background technique [0002] In recent years, with the development of printing technology, new types of printing ink technology have been continuously developed and applied. With the rise of the high-speed packaging industry, new challenges have been put forward for printing inks. Due to the high-speed packaging machinery running at high speed, it will generate frictional force on the printed matter, which will cause the printed matter to fade and decolorize. [0003] Traditional composite inks have relied on benzene-soluble chlorinated polypropylene resins for a long time, and benzene and ketones must be used as solvents. Due to the large amount of benzene and ketones used as solvents, food and medical plastic composite packaging in the flexible packaging industry printed with this ink The ink solvent residues contained in the ink exist for a l...

Problems solved by technology

[0003] Traditional composite inks have relied on benzene-soluble chlorinated polypropylene resins for a long time, and benzene and ketones must be used as solvents. Due to the large amount of benzene and ketones used as solvents, food and medical plastic composite packaging in the flexible packaging industry printed with this ink The ink solvent residues contained in the ink exist for a long time. According to the release rate and release characteristics (VOC) standard test results of pollutants, benzene and ketones exceed the standard, and benzene, ketones, xylene and other residues are very harmful to the human body, so food, There are long-term security risks in the pharmaceutical industry
