Abstract

The invention discloses a UV (ultraviolet) curing ink and application thereof. The UV curing ink comprises the following components in percentage by weight:30-40% of high-functionality polyurethane acrylate, 10-20% of dual-functionality polyurethane acrylic resin, 5-10% acidic acrylate prepolymer, 5-10% of thermoplastic acrylic resin, 10-15% of 1,6-hexanediol diacrylate and 2-4% of photosensitizer. When being printed on a glass workpiece, the UV photocuring ink is used for temporary protection in the glass surface working process. After the UV photocuring ink is subjected to UV photocuring, a tough ink layer, which has the advantages of favorable adhesion to glass, high surface hardness, favorable scratch resistance and favorable cutting fluid resistance, can be formed on the glass surface, and can effectively ensure the glass not to be scratched in the surface working process. After finishing the glass working, alkaline water can quickly remove the UV photocuring ink layer, so that the glass can not be influenced.

Description

technical field [0001] The invention relates to the field of inks, in particular to a UV-curable ink and applications thereof. Background technique [0002] At present, mobile phones are developing in the direction of smart phones, among which touch-screen mobile phones are popular, so glass is increasingly becoming a common and important material in mobile phone manufacturing. Usually mobile phone glass processing technology: glass raw material → cutting → profiling → fine carving → rough grinding → fine polishing → cleaning → strengthening → printing → packaging. Among them, rough grinding and fine polishing are mainly to solve the problem of glass being scratched in the first few processing processes, but the processing cost of these two processes is very high, and the dust has a great adverse effect on the health and safety of workers. [0003] Therefore, the existing technology needs to be improved and developed. SUMMARY OF THE INVENTION [0004] In view of the abov...
