Abstract

The invention belongs to the field of protection ink, and particularly relates to frosted metal protection ink. The frosted metal protection ink is prepared from, by weight, 15-25 parts of polyacrylate esterified by acrylic acid, 10-20 parts of thermoplastic phenolic resin, 5-10 parts of UV monomer, 5-15 parts of solvent and 35-55 parts of auxiliaries. The acid value of polyacrylate esterified by acrylic acid is 50-150 mgKOH / g. The polymerization degree of thermoplastic phenolic resin ranges from 2 to 20. By optimizing the formula of the protection ink and adding low-acid-value polyacrylate esterified by acrylic acid and thermoplastic phenolic resin with polymerization degree of 2 to 20 to the protection ink, the adhesive force of the protection ink to the surface of a metal plate is improved, and the ink removal time of the protection ink in the alkaline washing process is shortened.

Description

technical field [0001] The invention belongs to the field of protective inks, in particular to a protective ink for metal frosting. Background technique [0002] The frosting process of the metal plate usually includes the following steps: cleaning the metal plate, screen printing to protect the ink, ink drying, frosting, alkali washing to remove the ink, water cleaning the plate, drying treatment, varnish, drying and packaging. Protective ink is the key raw material for metal plate frosting process. The earliest protective ink used is solvent-based ink. This ink has the disadvantages of strong odor, slow ink drying, long ink baking line, high energy consumption and low production efficiency. question. Therefore, in order to reduce energy consumption and improve production efficiency, alkali-soluble UV-curable inks have been used in the field of protective inks in recent years. [0003] The Chinese patent with the application number 201410010072.4 discloses a UV curable al...
