Abstract

The invention discloses a high-temperature aluminum foil environment-friendly black ink and a preparation method thereof, and belongs to the technical field of ink. The high-temperature aluminum foil environment-friendly black ink is composed of the following components by the mass percentage: 35%-40% of composite resin, 30%-40% of a composite solvent, 15%-25% of a pigment, and 3%-5% of an auxiliary agent. The composite resin can significantly improve the thermal viscosity and resolubility of the aluminum foil ink, has excellent adhesive force on a metal surface, has good film-forming performance, has certain thermal endurance, and can improve flexibility, impact resistance and heat sealing property. The ink prepared by the composite resin enables the adhesive force to reach more than or equal to 98% at the temperature of 80-100 DEG C on an aluminum foil; the composite resin has good compatibility with resin and has good solvent release property, and the problem of solvent residues is greatly solved; non-benzene raw materials are adopted, so that the benzene residues are eliminated completely, and the ink is green and environmentally friendly; and at the same time, the preparation method is sample and feasible, low in preparation cost and easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a high-temperature aluminum foil environment-friendly black ink and a preparation method thereof. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, people's awareness of health and environmental protection has reached more stringent quality standards for pharmaceutical products and their packaging replacement. Therefore, the State Food and Drug Administration promulgated the "National Drug Packaging Container (Material) Standard" to standardize the order of the drug packaging market. [0003] The standard stipulates that the residual amount of solvent shall not exceed 10.0mg / m 2 , the residual amount of benzene solvent shall not exceed 3.0mg / m 2 1. The metal shall not exceed one part per million; for easy oxidation, use sodium thiosulfate 0.01mol / L, when the titration reaches the end point, add 0.25ml of st...
