Bubble-free solvent-free composite film processing method and dehumidification equipment

The invention relates to a bubble-free solvent-free composite film processing method which comprises the following steps: dehumidifying a processing workshop through dehumidification equipment, and carrying out unwinding, gluing and compounding by a plurality of material rollers in the processing workshop to form a composite film; extruding the composite film to discharge bubbles in glue between the films; rolling and feeding into a curing warehouse; wherein bubbles in glue between the films are extruded and discharged by adopting an extrusion device for pressurizing and exhausting, and a dehumidification device is arranged in a processing workshop for performing secondary dehumidification on air in the processing workshop, so that the humidity in the processing workshop is kept in a reasonable range, a glue layer on the composite film is prevented from reacting with the air to generate bubbles, and the service life of the composite film is prolonged. The finished product rate of the composite film in the pro
