Printing ink with high heat resistance

Abstract

The invention discloses a printing ink with high heat resistance. The printing ink is prepared from the following constituents in parts by weight: 5-10 parts of 1053 organic silicon resin, 2-4 parts of 9801 organic silicon resin, 1-2 parts of 804 organic silicon resin, 4-6 parts of thermoplastic acrylic resin, 10-15 parts of an alcohol-dissolving polyurethane solution, 9-10 parts of ternary hydroxyl-modified vinyl resin copolymer, 20-25 parts of a pigment, 20-25 parts of acetic acid, 22-25 parts of ethanol, 1-2 parts of ethyl acetate, 3-4 parts of acrylonitrile butadiene rubber, and 4-5 parts of acetone, wherein the mass concentration of the alcohol-dissolving polyurethane solution is 20-25%. The printing ink disclosed by the invention is high in heat resistance, is free of any change in color, any deformation and glue phenomenon when the temperature is larger than 100 DEG C, and is suitable for printing various materials; furthermore, the adhesive force is high, so that the pigment is durable and free of falling off; the printing ink is quick in drying, and the solvent on the printed material after printing is low in residual quantity, so that physical and psychological health for printing ink makers, pressmen and printed material users is guaranteed.

Description

technical field [0001] The present invention relates to a high heat resistance ink. Background technique [0002] In the prior art, the ink used for printing has poor heat resistance, and is easy to fade or become sticky and deformed at high temperature, and the applicable materials are limited; and a large amount of toxic solvents such as benzenes and ketones are used in the preparation. In the production process, when the solvent is not handled properly, it is easy to cause harm to the body of the production workers. When the ink is used for printing, the volatilization of the toxic solvent in the ink will also cause certain harm to the body of the printing worker, and a certain amount of residue will remain on the printed matter. Solvents are bound to affect the health of users of printed materials. Contents of the invention [0003] The purpose of the present invention is to provide a high heat-resistant ink, which has strong heat resistance and is suitable for printi...
