Abstract

The invention discloses a UV adhesive for sealing a quantum dot material. The UV adhesive is prepared through mixing, by weight, 20-70 parts of organosilicon chain segment polyurethane acrylate, 5-40 parts of organosilicon modified epoxy resin, 10-40 parts of an active diluent, 0.3-5 parts of a photoinitiator and 1-5 parts of an assistant, wherein the organosilicon chain segment polyurethane acrylate is modified polyurethane resin adopting a polysiloxane chain segment as a main chain and a methacrylate double bond function group as an end group; and the organosilicon modified epoxy resin is modified organosilicon resin adopting a polysiloxane chain segment as a main chain and an epoxy function group as an end group. Main resin is based on organosilicon, and the structure and the molecular weight of the resin are controlled, so the UV adhesive has excellent water and oxygen barrier performances, and the problem of poor water and oxygen barrier performances of traditional sealing materials is solved.

Description

technical field [0001] The invention relates to the field of sealants, in particular to a UV glue used for sealing quantum dot materials and a preparation method for the UV glue. Background technique [0002] Combining quantum dot display materials with LED backlight modules can improve the color gamut of the display and obtain better display effects. This new technology has already begun to be used in products such as LCD TVs, tablet computers and mobile phones. The key to the technology is to add a layer of quantum dot film between the LCD and the backlight module, and convert a part of the blue light of the blue LED backlight into red light and green light through the light conversion performance of the quantum dot material. Compared with the white light emitted by traditional LEDs, more pure red light and green light can be obtained, so the display is brighter and the colors are richer, and the color gamut of the display can be increased from 70% NTSC to 110% NTSC.
