▎ 摘  要

NOVELTY - Vacuum annealing furnace comprises a modified ethylene-vinyl acetate glue that includes ethylene-vinyl acetate resin, vinyl silicone resin, butadiene rubber, styrene-butadiene rubber, silica, graphene, carbon fiber, compatibilizer, antioxidant, flame retardant, polyvinyl alcohol and sodium carboxymethyl cellulose. USE - Vacuum annealing furnace for producing laminated glass. ADVANTAGE - The vacuum annealing furnace is quickly bonded, and has a broad application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing vacuum laminated glass, which involves: (A) coating one side of the vacuum glass with modified EVA glue on the outer surface of the glass, and then placing flat glass on the surface of the coated modified EVA glue; (B) placing vacuum glass on which flat glass into a double-chamber vacuum furnace, and putting it into a vacuum bag with a suction hole, and setting vacuum working room in the vacuum furnace; (C) simultaneously evacuating the vacuum working chamber and the vacuum bag for 30-60 minutes, where pressure is (0.1-1)x 10(-)3 Pascal, and raising temperature in the vacuum working chamber at 120-250 degrees C; (D) attaching modified ethylene-vinyl acetate adhesive between the flat glass and the vacuum glass in a molten state for 20-120 minutes; (E) bonding modified EVA adhesive tape firmly between the vacuum glass and the flat glass; and (F) opening the air release valve of the vacuum studio, after cooling to normal temperature, taking it out, removing the vacuum bag to get the finished laminated vacuum glass.
