Abstract

The invention discloses an ultraviolet light-curable silicone liquid optical adhesive composition, a preparation method and an application thereof. The ultraviolet light-curable organic silicon liquid optical adhesive composition comprises the following components in parts by weight: vinyl silicone oil 30 containing terminal mercapto groups ‑80 parts; 10‑50 parts of copolymer of thioalkanol siloxane and alkyl and / or aryl siloxane; 1‑60 parts of vinyl silicone oil; 0.01‑1 part of photoinitiator; tackifier 0.01-1 part; flame retardant 0.01-0.1 part. The UV-curable organic silicon liquid optical adhesive composition provided by the present invention has the properties of self-leveling and defoaming in a liquid state, fast curing, and low volume shrinkage, and can form a good fit with glass cover plates and LCD screens, and can be used for touch screens It has the advantages of high temperature and high humidity resistance, thermal shock resistance, high bonding reliability, high yield rate, and is suitable for continuous production.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular, the invention relates to an ultraviolet light-curable silicone liquid optical adhesive composition, a preparation method and an application thereof. Background technique [0002] In order to improve the display effect of the display screen under strong light or direct sunlight, and achieve light and thin, anti-vibration, anti-slip and waterproof effects, touch screen manufacturers and processing companies have developed a full lamination process. Full lamination means that the panel and the touch screen are seamlessly pasted together with liquid optical glue or optical tape, which can reduce the reflection and refraction of light on the display screen, improve the transmittance, increase the contrast, and improve the display effect indoors and outdoors . OCA optical adhesive is used to bond the upper and lower surfaces in the form of double-sided tape, which is prone to air bubb...
