Embodiment 1-6

[0076] Prepare the thermosetting liquid optical adhesive composition according to the components shown in Table 1.

[0077] Based on the total mass of the thermosetting liquid optical adhesive composition as 100%, the added amount of the components is the mass percentage. Since the addition amounts of the catalyst and the inhibitor are very small, the addition amount is based on the total mass of vinyl silicone oil, hydrogen-containing silicone oil and hydrogen-containing silicone resin as 100%.

Abstract

The invention provides a thermosetting liquid optical adhesive composition and an application thereof; the thermosetting liquid optical adhesive composition is tested according to a GB / T 4509-2010 asphalt needle penetration determination method, and the needle penetration of the thermosetting liquid optical adhesive composition is 160-250 mm. The thermosetting liquid optical adhesive provided by the invention has proper needle penetration after being cured, is easy to repair, does not greatly fluctuate along with the influence of temperature, humidity, UV aging irradiation and the like, and has higher cohesion strength, better binding power and excellent binding power for a binding material of a display module.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to a thermosetting liquid optical adhesive composition and an application thereof. Background technique [0002] From the perspective of the structure of the screen, the screen can be roughly divided into three parts, from top to bottom are the protective glass, touch screen and display screen, and these three parts need to be bonded, divided into three parts according to the bonding method Full fit and frame stickers. Frame stickers are also called word-of-mouth glue bonding, that is, the four sides of the touch screen and the display screen are simply fixed with double-sided tape, and there is an air layer between the display screen and the touch screen; full bonding refers to the use of liquid optical glue to connect the display module with the The touch panel / cover is seamlessly bonded together. Compared with frame mounting, liquid glue or optical tape is used to fill the air l...
