Abstract

The invention relates to the field of sealants, and discloses a radiation-curable quantum dot material sealant composition, comprising: 25-50 parts of organosilicon-modified hyperbranched acrylate, 10-parts of organosilicon-modified polyurethane acrylate 30 parts, 15-60 parts of reactive diluent, 0.1-4 parts of photoinitiator, 0.5-5 parts of auxiliary agent. The present invention adopts organosilicon-modified hyperbranched acrylate as the main resin of the sealant, which effectively reduces the water-oxygen transmission rate, has higher bonding strength, has good compatibility with quantum dot materials, and has an impact on the luminous efficiency of quantum dots. It is small, has excellent weather resistance, excellent water and oxygen barrier performance, and can play a very effective protective function on quantum dot materials.

Description

technical field [0001] The invention relates to the field of sealants, in particular to a radiation-curable quantum dot material sealant composition. Background technique [0002] Liquid crystal technology will usher in the "ultimate evolution" of the backlight system - quantum dot technology. Quantum dot display can be divided into photoluminescence and electroluminescence according to the different luminescence principles, which are respectively called quantum dot backlight technology (QD -LCD) and Quantum Dot Light Emitting Diode display technology (AMQLED). [0003] AMQLED is a self-luminous technology that does not require an additional light source, and its luminous principle and structure are similar to OLED technology. AMQLED has not yet been commercialized. The main reason is that the quantum dots of AMQLED are easily affected by heat and moisture. The industry believes that it will take at least 10 years before the commercialization of the real version of AMQLED. ...
