Abstract

The invention provides a peelable glue coating composition and a peelable glue coating as well as a preparation method and an application of the peelable glue coating. The peelable glue coating composition comprises the following components in parts by weight: 80-120 parts of an acrylate type oligomer, 8-20 parts of a dilutive monomer, 0.1-1.5 parts of a peeling force modifying agent, 2-12 parts of a triggering agent and 30-50 parts of an organic solvent. The peelable glue coating composition is relatively high in transparency and relatively high in light transmittance and relatively low in haze after film formation. Meanwhile, a coating formed by curing the peelable glue coating composition is relatively high in high temperature resistance and relatively high in peelability. By the high temperature resistance, the coating is good in adhesion property on the surface of a functional hardened layer, and the problems of air bubbles and warping can be effectively improved. By the peelability, the problem of glue layer residues caused during peeling of the coating can be reduced.

Description

technical field [0001] The invention relates to the field of ITO-film manufacture, in particular to a peelable adhesive coating composition, a peelable adhesive coating, a preparation method and an application of the peelable adhesive coating. Background technique [0002] At present, touch screen technology has been widely used in mobile phones, notebook computers, tablet computers and other fields, among which transmissive capacitance, OGS (One Glass Solution, single-chip touch panel), in-cell, and on-cell are the current mainstream technology. With the increasing size and thinning of touch screens, the OGS technology has more compressed the market share of the transmissive capacitive technology. The most critical core technology in touch screen technology is the use of ITO-film in its entire assembly. ITO-film products are not only used on touch screens, but also widely used in other flexible display devices, such as electronic paper books, OLED, etc. On the other hand...
