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
The present invention relates to technical field of ink, particularly relate to a kind of high temperature foil environment-friendly black ink and preparation method thereof.
Background technology
Along with the progress of China's expanding economy and living standards of the people, the health perception of people and environmental consciousness have reached the stricter quality standard for pharmaceutical products and its packaging update.Therefore, State Food and Drug Administration has promulgated " national drug packaging vessel (material) standard ", with this standard specifications drug packaging city field sequential.
This standard specifies: solvent residual amount must not more than 10.0mg/m
2, wherein benzene solvent residual quantity must not more than 3.0mg/m
2, metal must not more than 1,000,000/; Readily oxidizable substance Sulfothiorine 0.0lmol/L, when being titrated to terminal, adds starch indicating liquid 0.25ml, continues to be titrated to colourless, and another water intaking vacancy liquid is handled with method, and the two consumes titrating solution must not more than 1.5ml.
At present, for the aluminum foil ink of pharmaceuticals packaging, ubiquity overrun metal content, benzophenone content overproof, produces the defects such as the temperature height of sticking power, wherein, when current ink is used for aluminium foil printing, generally need to reach 170 ~ 210 DEG C, its sticking power just can reach more than 85%, consumes energy excessive during printing.
