Corrosion-resistant photo-curing ink and preparation process thereof

Abstract

The invention discloses corrosion-resistant light-cured ink and a preparation process thereof. The corrosion-resistant light-cured ink comprises the following raw materials in parts by weight: 40-60 parts of modified phenolic epoxy resin, 80-100 parts of bisphenol A epoxy acrylate, 5-6 parts of a reactive diluent, 5-7 parts of a photoinitiator, 4-6 parts of a modified defoamer, 4-6 parts of nano zinc powder, 15-30 parts of a coloring pigment, 1-2 parts of a BYK333 leveling agent and 1-3 parts of an AKN-2280 dispersing agent. The preparation method comprises the following steps of: S1, preparing mixed light-cured resin; S2, adding nano zinc powder and a coloring pigment, performing stirring and dispersing to obtain a corrosion-resistant light-cured ink primary material; and S3, performing grinding and filtering to obtain the corrosion-resistant light-cured ink. The light-cured ink prepared by the invention has good corrosion resistance and curing performance, and can effectively protect the appearance of a metal product after being applied onto the surface of the metal product and cured.

Description

technical field [0001] The invention belongs to the technical field of photocurable inks, and in particular relates to a corrosion-resistant photocurable ink and a preparation process thereof. Background technique [0002] Photocurable ink refers to the ink that can form a film and dry under the irradiation of ultraviolet light. The ink has good mechanical and chemical properties after film formation. It is widely used in industries such as metal mobile phone shells, digital cameras, MP4, notebook shells, etc. At present, UV ink has become a relatively mature ink technology, and its pollutant discharge is almost zero. In addition to not containing solvents, UV inks also have the advantages of not easy to smear, clear dots, bright and bright ink colors, excellent chemical resistance, and saving usage. They have a wide range of applications. [0003] UV ink has the characteristic of selectively absorbing UV light. Drying is affected by the total energy of the radiated light...

AI Technical Summary

Problems solved by technology

[0004] In the process of transportation and packaging of stainless steel craft products, problems such as bumps, scratches, and deformation often occur, and stainless steel will be corroded and denatured when placed and displayed for a long time, which will lead to corrosion resistance on the surface of stainless steel craft products. Corroded spots will affect the appearance of stainless steel handicrafts. Therefore, the metal surface is usually coated with an anti-oxidation and anti-corrosion protective layer to maintain the appearance and performance of stainless steel handicrafts as much as possible.
