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% of amine-modified polyether acrylate prepolymer, 5-10% of thermoplastic acrylic resin, 10-15% of 1,6-hexanediol diacrylate, 2-4% of photosensitizer, 1-2% of nano aluminum oxide dispersion and 15-20% of filler. The UV photocuring ink is used for temporary protection in the glass surface working process; and after the UV photocuring ink is subjected to UV photocuring, a tough ink layer can be formed on the glass surface, thereby effectively ensuring the glass not to be scratched in the surface working process. After finishing the glass working, the glass can be soaked in 5% sulfuric acid solution, which is heated to 50 DEG C, to remove the UV curing ink on the glass surface without influencing the glass.

Description

technical field [0001] The invention relates to the field of inks, in particular to a UV curable ink and its application. 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 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, coarse 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 prior art needs to be perfected and developed. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, ...
