Beschreibung
Zusammenfassung:	The invention discloses a polyethylene foamed master batch. The polyethylene foamed master batch comprises the following components in parts by weight: 40-60 parts of polyvinyl chloride, 20-30% of a plasticizer, 15-25 parts of a filler, 2-5 parts of a stabilizer, 0.05-1 part of an antioxidant, 0.5-1.5 parts of a lubricant and 1-2 parts of a foaming agent. A preparation method for the polyethylene foamed master batch comprises the following steps: mixing and discharging the composition through a high-speed mixer; and extruding and pelletizing in a screw extruder to obtain the polyethylene foamed master batch. The polyethylene foamed master batch disclosed by the invention and a polyvinyl chloride cable are mixed in a ratio of (1-40) to (99-60) and then extruded to prepare a cable. The material usage amount can be effectively reduced and the production cost can be reduced.
