Abstract

The invention provides a high-efficiency insulating polyvinyl chloride cable sheath material and a preparation method thereof, and relates to the technical field of cable sheath production. The cable sheath material is prepared from the following raw materials in parts by weight: 40-50 parts of polyvinyl chloride, 15-20 parts of fluorinated ethylene propylene, 10-15 parts of silicon rubber, 8-12 parts of polyamide-imide resin, 1-2 parts of nano talcum powder, 0.6-1.0 part of a coupling agent, 3-5 parts of E-type epoxy resin, 6-8 parts of cyclohexane diglycidyl dicarboxylate, 4-6 parts of dioctyl sodium sulfosuccinate, 2-3 parts of powder mica, 4-5 parts of aluminum nitride, 2.5-3.0 parts of barium sulfate, 1-2 parts of zeolite powder, 2-4 parts of a curing agent and 2-4 parts of a vulcanizing agent. The invention overcomes the defects in the prior art, so that insulation performance of the cable sheath material can be effectively improved, the risk of electric shock of users is prevented, and then safety is high; and moreover, flame retardancy of the cable sheath material can be effectively improved. The cable sheath material is excellent in overall performance and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of cable sheath production, in particular to a highly insulated polyvinyl chloride cable sheath material and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. An insulating covering used to connect electrical circuits, appliances, etc. The cable has the characteristics of internal electrification and external insulation. The outer covering of the cable conductor is the cable sheath, which is used to protect the inner conductor and prevent the user from getting an electric shock. [0003] At present, the insulation performance of the cable sheath material is poor, so when the wire in the cable is energized, it is very easy to transmit the electricity to the outside through the conductive cable sheat...
