Abstract

The invention relates to optical transparent adhesive and in particular relates to an organosilicon material OCA as well as a preparation method and application thereof. The organosilicon material OCA comprises the following components by mass percent: 30-70% of (methyl) acrylate terminated polysiloxane, 5-30% of MQ silicon resin, 0-30% of silane coupling agent containing methylacryloyloxypropyl, 0.5-5% of photoinitiator and 0-5% of oxygen scavenging agent. The organosilicon material OCA has the advantages of high-temperature resistance, low yellowing probability, good light transmittance (greater than 94%) and the like; meanwhile, the preparation method and application are easy and quick to operate, so that the organosilicon material OCA has a good industrial popularization prospect.

Description

technical field [0001] The invention relates to an optically transparent adhesive, in particular to an organic silicon material OCA and its preparation and application. Background technique [0002] With the advent of the smart mobile era, tablet PCs and touch-screen mobile phones have become increasingly popular. In the past, the limitation of mobile phones was the communication function. However, the performance of smart devices including smartphones and tablet PCs is close to that of notebooks. The convenience of performing and enjoying high-level business and entertainment activities all the time. For this reason, people have higher and higher requirements on the visual effect of the display panel. [0003] The trend of filling the air layer between the touch screen and the display panel (LCD, OLED) to improve visibility is in many ways a very logical development. OCA (Optically Clear Adhesive) is an optically transparent adhesive. Using OCA to fill the air layer betwe...
