Abstract

The invention discloses an ultraviolet-curing organosilicon liquefied optical adhesive composition, a preparation method and an application thereof. The ultraviolet-curing organosilicon liquefied optical adhesive composition comprises the following components in parts by weight: 30-80 parts of vinyl silicone oil containing end-sulfydryl group, 10-50 parts of thioalkyl and alkyl group and / or aryl siloxane copolymer, 1-60 parts of vinyl silicone oil, 0.01-1 part of photoinitiator, 0.01-1 part of viscosifier and 0.01-0.1 part of flame retardant. The ultraviolet-curing organosilicon liquefied optical adhesive composition provided by the invention has the properties of liquid-state self-leveling bubble removal, rapid curing and low volume shrinkage rate and the like, can form good attachment with a glass cover plate and an LCD (Liquid Crystal Display) screen, and can be used for whole attachment with a touch screen; the light transmittance reaches more than 99%, and simultaneously the ultraviolet-curing organosilicon liquefied optical adhesive composition has the advantages of high-temperature and high-humidity resistance and cold-heat impact resistance and the like, is high in attachment reliability and finished-product 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...
