Abstract
The invention discloses twice-cured liquid optical cement, which is prepared from the following raw materials in parts by mass: 0-60 parts of liquid rubber, 20-50 parts of acrylic ester monomers, 2-10 parts of a reactive diluent, 0.5-2 parts of an antioxidant, 0.2-2 parts of a radical initiator, and 0.2-6 parts of a photoinitiator. A preparation method of the twice-cured liquid optical cement comprises the following steps of: uniformly mixing the components except for the fluid rubber, adding the fluid rubber, and mixing uniformly. The twice-cured liquid optical cement has the advantages that when a large-size touch screen is bonded by the cement, the problem that air bubbles are difficult to remove does not exist, and the phenomenon of cement overflow does not occur.
