ONE-TIME REACTION EXTRUSION MOLDING PRODUCTION LINE FOR ACRYLIC PLATES

WIPO Patent Application WO/2021/114955

A1

The present invention relates to a one-time reaction extrusion molding production line for acrylic plates, comprising a reaction kettle having an MMA feed pipe, an initiator adding device and a plurality of tubular reactors being connected in series to a lower part of the reaction kettle by means of a discharge valve, and then the lower part of the reaction kettle being connected to an inlet of a screw devolatilization device, an exhaust port of the screw devolatilization device being connected to an upper part of the reaction kettle by means of a condenser, an extrusion port of the screw devolatilization device being connected to a cylindrical inlet at one end of a material uniforming and feeding barrel, the middle part of the material uniforming and feeding barrel having a structure that smoothly transitions from the cylindrical inlet at one end to a horizontal rectangular elongated outlet at the other end, and the horizontal rectangular elongated outlet at the other end of the material uniforming and feeding barrel being connected to a plate-molding device. The production line can take account of both the one-time full polymerization reaction of raw materials, and the stable extrusion molding production of plates having various lengths, has no volatile gas pollution, and has good molding quality, high production efficiency and low costs.
