Problems solved by technology

[0002] Samsung Electronics officially launched its first folding screen mobile phone, the Galaxy Fold, in August 2019. At that time, the foldable glass cover had not yet been mass-produced, so a transparent polyimide film (CPI) was used as the protective cover, but CPI’s scratch-resistant Scratch, anti-crease, poor impact resistance, insufficient protection for flexible OLED panels, leading to various accidents of Samsung Electronics Galaxy Fold
[0003] However, the thickness of the existing UTG for Samsung mobile phones is very thin (about 30um), and the production yield is very low.

Abstract

The invention discloses a foldable ultra-thin glass (UTG) explosion-proof membrane ink, a preparation method and a use method thereof. The explosion-proof membrane ink comprises the following components by weight: 20-65 parts of epoxy resin, 30-75 parts of a solvent, 0.1-2 parts of an antifoaming agent, 0.5-2 parts of a leveling agent and 1-5 parts of a glass adhesion promoter. The explosion-proofmembrane ink is mixed with a flexible curing agent to act on foldable ultrathin glass, and has the advantages of no cracking, no separation, yellowing resistance, no foaming, good leveling effect, enhancement of UTG toughness and the like, and can effectively adapt to an intaglio pad printing process and a silk-screen printing process.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof film ink, and in particular relates to a foldable ultra-thin glass explosion-proof film ink, a preparation method and a use method thereof. Background technique [0002] Samsung Electronics officially launched its first folding screen mobile phone, the Galaxy Fold, in August 2019. At that time, the foldable glass cover had not yet been mass-produced, so a transparent polyimide film (CPI) was used as the protective cover, but CPI’s scratch-resistant Scratch, anti-crease, poor impact resistance, insufficient protection for flexible OLED panels, leading to various accidents of Samsung Electronics Galaxy Fold. Samsung Electronics then launched a foldable smartphone, the Galaxy Z Flip, in early 2020 using foldable ultra-thin protective glass (UTG) as a protective cover, solving the problem of CPI as a protective cover. The industry predicts that by 2021, foldable mobile phones will form a mark...
