Abstract

The invention relates to the field of display technology, in particular to UV glue for package and a preparation method thereof. The UV glue for package is prepared from an acrylic ester prepolymer, modified bisphenol-A epoxy resin, a reactive diluent, a photoinitiator, an addition agent, and inorganic porous particulate matter.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a UV glue for encapsulation and a preparation method thereof. Background technique [0002] With the rapid development of the information age, liquid crystal displays (LCDs) are used more and more widely, and are gradually becoming mainstream displays, widely used in electronic devices. As an important material for LCD production, UV glue plays a key role in the LCD industry. However, UV glue is an organic material, and after curing, the molecular gap is relatively large, and water vapor and oxygen can easily penetrate the medium to reach the internal sealing area. Since OLED devices are very sensitive to water vapor and oxygen, they are packaged with UV glue. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a UV glue for encapsulation and a preparation method thereof. [0004] According to one aspect of the present inve...
