Environment-friendly printing ink with high adhesive force

Abstract

The invention discloses an environment-friendly printing ink with high adhesive force. The environment-friendly printing ink is prepared from the following constituents in parts by weight: 10-13 parts of an alcohol-dissolving polyurethane solution, 15-18 parts of ternary hydroxyl-modified vinyl resin copolymer, 35-38 parts of a pigment, 25-29 parts of acetic acid, 18-20 parts of ethanol, 18-20 parts of rosin pentaerythrityl ester, 5-8 parts of microcrystalline wax, and 5-6 parts of acrylonitrile butadiene rubber, wherein the mass concentration of the alcohol-dissolving polyurethane solution is 36-38%. The environment-friendly printing ink with the high adhesive force disclosed by the invention is high in adhesive force, and suitable for printing various materials; the pigment is durable and free of falling off; the printing ink is quick in drying, bright in color, and free of toxic substances in the constituents; the solvent on the printed material after printing is low in residual quantity, so as to guarantee physical and psychological health for printing ink makers, pressmen and printed material users; the printing ink is good in adaptability, can be used for different seasons to obtain identical printed products, and is good in printing effect.

Description

technical field [0001] The invention relates to a high-adhesion environment-friendly ink. Background technique [0002] In the prior art, inks use organic solvents as solvents, causing great environmental pollution. In the flexible packaging industry, since solvent-based inks are mainly volatile and dry, the lower the boiling point of the solvent, the easier it is to volatilize and release toxic gases to pollute the environment. After printing, there are residual toxic substances on the surface. The ink used for printing has weak adhesion, the pigment is easy to fall off, and the applicable materials are limited; a large amount of toxic solvents such as benzenes and ketones are used in its preparation. When the solvent is not handled properly during the ink production process, It is easy to cause harm to the body of production workers. When the ink is used for printing, the volatilization of toxic solvents in the ink will also cause certain harm to the body of the printing ...

Problems solved by technology

The ink used for printing has weak adhesion, the pigment is easy to fall off, and the applicable materials are limited; a large amount of toxic solvents such as benzenes and ketones are used in its preparation. When the solvent is not handled properly during the ink production process, It is easy to cause harm to the body of production workers. When the ink is used for printing, the volatilization of toxic solvents in the ink will also cause certain harm to the body of the printing workers. A certain amount of solvent will also remain on the printed matter, which will inevitably affect the printed matter. User's health
