Abstract

The invention discloses a peelable blue plastic and a preparation method thereof. The peelable blue plastic comprises the following components in parts by weight: 60-150 parts of UV curing resin A, 60-150 parts of UV curing resin B, 0.05-0.1 part of a leveling agent, 1-10 parts of a wetting agent, 0.2-1 part of a defoamer, 1-10 parts of UV color paste, 3-5 parts of a photoinitiator A and 3-5 parts of a photoinitiator B. After coating, through irradiation of a 365 nm UV LED lamp, the peelable blue plastic coating is high in curing ability, good in binding force, easy to peel, complete in peeling, and free of residue; the peelable blue plastic can be applied to insulation protection, moisture and pollution prevention and anti-scratch protection of materials of PET, ITO conductive films, ITO glass, mobile glass, tempered glass windows and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a strippable blue glue and a preparation method thereof. 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 inks with anti-corrosion functions or "peelable blue glue" and "surface protection glue" for metal surface processing protection. When manufacturing printed boards, some parts of the board are often covered with peelable glue to avoid being splashed by tin when soldering, such as gold fingers, interface cards, carbon conductive keys and large-area boards, all of which require Selective soldering and multiple continuous soldering, such as SMD mixed assembly, reflow soldering manual and automatic and other soldering processes, etc. Drawing on the protection method of the peelable blue glue i...
