LCD sealing glue obtained by nanometer heat-resistant modification ODF technology and preparation method thereof

The invention relates to LCD sealing glue obtained by a nanometer heat-resistant modification ODF technology. The LCD sealing glue comprises a single component and is suitable for ODF construction. The component comprises cycloaliphatic epoxide resin, a curing agent, acrylic resin, aliphatic acrylate, an epoxy active diluent, a free radical photoinitiator, a nanometer inorganic filling material, an antifoaming agent and a coupling agent. The LCD sealing glue has the characteristics that 1, the LCD sealing glue is not influenced by sizes and types of panels and is suitable for large-scale screen printing sizing production, 2, excellent high and low temperature change-resistant performances are obtained, 3, alicyclic epoxy resin and aliphatic acrylate are combined, light-curing and heat-curing processes are adopted, curing time is shortened and sealing glue pollution on liquid crystal is reduced, and 4, the LCD sealing glue has low hygroscopicity and excellent electrical insulating properties, does not pollute liquid crystal, replaces the same type of imported product and is initiative in China.
