 The present invention will be further described below.
 PVC black masterbatch of the present invention is used for PVC cable material, and its composition by mass parts is:
 The plasticizer is a mixture of pentaerythritol esters and trioctyl trimellitate;
 Described stabilizer is zinc stearate;
 Dispersant A is white oil;
 Dispersant B is a mixture of polyethylene wax homopolymer and ethylene-vinyl acetate copolymer wax.
 The process flow is as follows: Dispersant A, pigment black, carbon black, and plasticizer are first ground; then mixed with stabilizer, dispersant B, carrier polyvinyl chloride and other additives, and stirred in a high-speed kneader; finally Extruder granulation.
 The addition amount of the masterbatch in PVC resin is 3-5 parts.
