Abstract

The invention discloses peelable blue gel which is prepared from the following ingredients in parts by weight: 50-80 parts of UV curable resin A, 50-80 parts of UV curable resin B, 50 to 80 parts of UV curable resin C, 0.05-0.1 part of a flatting agent, 1-10 parts of a wetting agent, 0.2-1 part of a defoamer, 1-10 parts of a color paste, 3-5 parts of a photoinitiator A and 3-5 parts of a photoinitiator B. The invention further provides a preparation method of the peelable blue gel. The preparation method comprises the following steps: adding the wetting agent, the flatting agent, the defoamer and the color paste into a high-speed dispersion machine; after dispersing, adding the UV curable resin A, the UV curable resin B, the UV curable resin C, the photoinitiator A and the photoinitiator B, and further dispersing; and mixing uniformly, thereby obtaining the peelable blue gel. After being coated and irradiated by a 395nm UV LED lamp, the peelable blue gel has rapid curing capability, good binding force, no peeling and falling, and easiness for peeling.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a peelable 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 in the printe...
