Co-extrusion type water-air sealing composite conductive rubber strip

The invention relates to a co-extrusion type water-air sealing composite conductive rubber strip and belongs to the technical field of composite conductive rubber strips. The co-extrusion type water-air sealing composite conductive rubber strip meets the special demand of coastal and deep-sea equipment for an electromagnetic sealing strip and comprises a conductive part and a non-conductive part, wherein the conductive part and the non-conductive part can constitute a solid composite conductive rubber strip or a hollow composite conductive rubber strip; raw materials of the conductive part and the non-conductive part are weighed according to a formula and are subjected to mixing by a rubber mixing mill, the uniformly mixed materials are fed into extruder cylinders respectively, the temperature of each cylinder is controlled in a range from 10 DEG C to 25 DEG C by the aid of cooling water, the extrusion speeds are adjusted to be lower than 50 m/h, the extrusion speeds of two extruders are matched with each oth
