Abstract

The invention discloses a peelable blue gel and a preparation method. The peelable blue gel comprises, by weight, 50-80 parts of UV cured resin A, 50-80 parts of UV cured resin B, 50-80 parts of UV cured resin C, 0.05-0.1 part of flatting agent, 1-10 parts of wetting agent, 0.2-1 part of defoamer, 1-10 parts of color paste special for UV nail polish, 3-5 parts of photoinitiator A and 3-5 parts of photoinitiator B. After being irradiated by a 365nm UV-LED light, the peelable blue gel can be cured rapidly, has good binding force without peeling off, is easy to peel completely without residue, and can be applied to insulation, damp proof, pollution prevention, scratch protection of materials such as PET and ITO conducting films, ITO glass, glass of cellphones and tempered glass windows.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and specifically relates to a peelable blue glue and a preparation method. The peelable blue glue is particularly suitable for 365nm UV-LED light source irradiation curing. Background technique [0002] In recent years, the rapid development of digital products has driven the rapid development of the touch screen industry. The high-performance touch screen preparation process requires ink with corrosion resistance function or "peelable blue glue" and "surface protective glue" for metal surface processing protection. In the manufacture of printed boards, some parts of the board are often covered with peelable glue to prevent the tin from being poured during soldering. For example, gold fingers, interface cards, carbon conductive buttons and large-area board surfaces are required. Selective soldering and multiple continuous soldering, such as mixed assembly of SMD, manual and automatic reflow...
