Abstract

The invention provides a production method for cation ultraviolet light curing frame glue used for an organic electroluminescence displayer. The production method includes the following steps that 1, with chloroplatinic acid as a catalyst, hydrogen-terminated silicone oil and allyl glycidyl ether react to obtain polysiloxane modified epoxy resin; 2, gap phase SiO2 powder is added into a coupling agent diluent and evenly mixed, and the mixture is dried to obtain modified gap phase SiO2 powder; 3, a diluent, cation photoinitiator, the polysiloxane modified epoxy resin and the modified gap phase SiO2 powder are evenly mixed to obtain the cation ultraviolet light curing frame glue used for the organic electroluminescence displayer. The frame glue still has excellent flexibility without addition of any solvent or participation of any tenacity modifying agent, after the frame glue is cured through ultraviolet light, the water vapor penetration rate, the oxygen penetration rate, the bonding strength, volatile gas performance and other properties of the frame glue can meet the requirement of national standards, and the production method has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic packaging materials, and in particular relates to a production method of cationic ultraviolet light curing frame glue for organic electroluminescent displays. Background technique [0002] Organic electroluminescence display (OLED) is a key support project of my country's information industry. my country has become a major producer of flat panel displays. Light guide plates, organic light-emitting materials, and packaging materials are all controlled by foreign companies. The frame glue material of an organic electroluminescent display is one of the key factors affecting its lifespan. Its function is to block water vapor and oxygen from penetrating into the device, because the entry of a small amount of water vapor and oxygen will greatly reduce the life of the device. At the same time, it is also required that the frame glue material has excellent properties such as short curing time, low...
