Abstract

The invention discloses plastic plate molding equipment. The equipment comprises a first plastic extruding machine, a second plastic extruding machine, a third plastic extruding machine, first guide rollers, an upper-layer nonwoven fabric layer unwinding equipment first unwinding device, a lower-layer nonwoven fabric layer unwinding equipment second unwinding device, second guide rollers and traction devices which are arranged sequentially, wherein the first plastic extruding machine is used for extruding a middle-layer heat-insulation plate; the second plastic extruding machine is used for extruding an upper plastic sheet layer; the third plastic extruding machine is used for extruding a lower plastic sheet layer; a setting mold is fixedly connected onto a first setting device; a heat-insulation plate machine head is mounted on the first plastic extruding machine, an extruded heat-insulation plate blank is cooled and set by the setting mold of the first setting device, and a continuous heat-insulation plate is formed; the middle-layer heat-insulation plate, the modified plastic sheet layer on the upper side, the modified plastic sheet layer on the lower side and grid fabric or nonwoven fabric are bonded together in a hot-melt manner respectively; the heat-insulation plate is made of polystyrene (PS), polyvinyl chloride (PVC), polyurethane (PU), polypropylene (PP), polyethylene (PE) and ethylene-vinyl acetate (EVA); and the plastic sheet layers are made of PVC, PP, PE and PU. The grid fabric or the nonwoven fabric or a polymer adhesive layer has the good bonding property to a wall and does not fall off easily, and the service life is long.

Description

Technical field [0001] The invention relates to a plastic plate and molding equipment, belonging to the field of plastic molding processing, and is mainly used for building partitions, wall insulation, interior wall decoration, ceilings and the like. Background technique [0002] The main materials for building partitions, wall insulation, interior wall decoration, and ceilings are extruded polystyrene board (XPS) insulation board, molded polystyrene insulation board (EPS) or polyurethane insulation board (PU), etc., usually The above materials are made into foamed foam boards. During construction, glue or cement paste is used to paste on the wall. The bonding strength between the insulation board and the wall material is not high, and it is unavoidable to shrink and deform under the influence of ambient temperature, which is easy to repair The wall separates and falls off; in addition, the technical level of the construction personnel is relatively high, and the quality is not e...
