Problems solved by technology

[0002] At present, there are two kinds of gravure printing inks that are most used in food packaging: one is flexible packaging ink with polyamide (PA) resin as the binder, and this ink uses benzene as the main solvent; the other is based on polyurethane Composite ink with resin as binder, such as two-component polyurethane composite ink that is widely used at present, component A of main agent is polyurethane ink containing hydroxyl group, curing agent B is polyurethane oligomer containing isocyanate group, because group A Part needs to react with component B through the hydroxyl group of its polyurethane molecular chain, so if the system contains sol

Abstract

The invention provides a high-temperature resistant ester-soluble printing ink, belonging to the field of ink printing. The ink comprises the following components in percentage by weight: 5-20% of ester-soluble acrylic resin, 5-15% of nitrocotton, 5-35% of organic or inorganic pigment, 2.2-11% of assistant and 35-80% of mixed solvent. The ink is mainly used for gravure food paper packages and has the following advantages of high gloss, good levelling and good printing color development performance; due to low viscosity, the ink hardly causes falling of paper fibers or stains paper when used for printing; due to high drying speed, no solvents such as benzene, ketone or the like and little solvent residue, the ink meets the requirements of human safety and environmental protection and suitable for food package printing; and due to the high-temperature resistance, the ink can resist 180 DEG C high temperature at most and is capable of sealing heat without losing color.

Description

technical field [0001] The invention relates to the field of ink printing in the chemical industry, in particular to a high-temperature-resistant ester-soluble printing ink, which can be printed on food packaging substrates by means of gravure printing. Background technique [0002] At present, there are two kinds of gravure printing inks that are most used in food packaging: one is flexible packaging ink with polyamide (PA) resin as the binder, and this ink uses benzene as the main solvent; the other is based on polyurethane Composite ink with resin as binder, such as two-component polyurethane composite ink that is widely used at present, component A of main agent is polyurethane ink containing hydroxyl group, curing agent B is polyurethane oligomer containing isocyanate group, because group A Part needs to react with component B through the hydroxyl group of its polyurethane molecular chain, so if the system contains solvents (alcohols or water) with hydroxyl groups, it w...
