Abstract
The invention discloses strippable blue gel and a preparation process thereof. The strippable blue gel is prepared from, by weight, 50-80 parts of UV-cured resin A, 50-80 parts of UV-cured resin B, 0.05-0.1 part of leveling agent, 1-10 parts of wetting agent, 0.2-1 part of defoaming agent, 1-10 parts of blue UV color paste, 3-5 parts of photoinitiator A and 3-5 parts of photoinitiator B. After being painted with film, the strippable blue gel can be quickly cured under irradiation of 365 nm UV rays, and the curing time is 1-10 s. The strippable blue gel is good in binding force, free of peeling and falling and easy to strip, stripping is complete, and no residues are left; the strippable blue gel can be applied to insulation, damp resistance, contamination resistance and scratch resistance of materials such as PET and ITO conducting film, ITO glass, mobile phone glass and tempered glass windows.
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 process thereof. The strippable blue glue is particularly suitable for curing by irradiation with a 365nm UV-LED light source. 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 ...
