NOVELTY - Semi-conductive shielding material comprises 100 pts. wt. ethylene butyl acrylate resin, 25-40 pts. wt. conductive carbon black, 4-8 pts. wt. functional additives, the conductive carbon black includes high oil absorption value conductive carbon black and low oil absorption value conductive carbon black, the high oil absorption value conductive carbon black has an oil absorption value of 300 ml/100g-400 ml/100 g, the low oil absorption value conductive carbon black has an oil absorption value of 120 ml/100 g-220 ml/100 g, the weight ratio of the high oil absorption value conductive carbon black and the low oil absorption value conductive carbon black is 1: (2-4). USE - The high voltage cable semi-conductive shielding material is useful for high-voltage cables. ADVANTAGE - The high voltage cable semi-conductive shielding material has good conductivity, mechanical performance and peeling adhesive property, improves the conductivity and mechanical performance caused by the graphene, overcomes the bad effect that the high voltage cable semi-conductive shielding material must be added with a large amount of carbon black to obtain the pre-determined electric conductivity and the bad influence of the molding and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high voltage cable semi-conductive shielding material comprising (1) according to the weight proportion, adding the conductive carbon black into the removing water, mixing with the functional auxiliary agent, (2) mixing the mixture obtained in the step (1) with ethylene butyl acrylate resin at 45-50 degrees C, (3) melting and extruding the mixture obtained in the step (2) in a double-screw extruder, drawing in water, cutting and drying to obtain the semi-conductive shielding material.
