Abstract

The invention provides an optically transparent glue composition with organic silicone liquid.The optically transparent glue composition mainly comprises acrylate-terminated vinyl silicone oil, vinyl MQ silicone resin, vinyl MDT silicone oil, tackifiers, hydrogen-containing silicone oil, photoinitiators, catalysts, inhibitors and the like.The invention further provides a method for preparing the optically transparent glue composition.The method includes proportionally preparing materials; blending the materials to obtain mixtures; purifying the mixtures; defoaming the mixtures at high speeds and packaging the mixtures at high speeds.The optically transparent glue composition and the method have the advantages that glue with the organic silicone liquid can be simultaneously subjected to ultraviolet curing and heat curing, accordingly, the problem of incapability of completing curing on the peripheral edges of screens at one step can be solved, production processes and the manufacturing time can be greatly shortened, the reject ratio of finished products can be reduced, and effects of saving energy and time, reducing the production cost and improving the productivity can be realized; the glue is excellent in impact resistance, bending resistance, high-temperature and high-humidity resistance and yellowing resistance and low in dimensional contraction rate after being cured; bubble and impurities in the optically transparent glue with the organic silicone liquid can be prevented by the aid of the method.

Description

technical field [0001] The invention relates to an optical adhesive and a preparation method thereof, in particular to a liquid optical adhesive and a preparation method thereof. Background technique [0002] The iPad Air 29.7 product launched by Apple in 2014 adopts full lamination technology, and the application scope of this technology has gradually spread from smartphones to medium and large-sized products such as tablets and notebook computers. Full lamination means that the panel and the touch screen are seamlessly pasted together with liquid glue or optical tape. Compared with frame paste, liquid glue or optical tape is used to fill the air layer between the touch screen and the display panel. On the one hand, it can Reduce glare and reduce the loss of light emitted by the LCD; increase the contrast (especially under strong light); improve the visibility and display performance indoors and outdoors, and the display effect is better. On the other hand, it is also help...
