Abstract

The invention discloses an insulating sheath material for a silicone rubber cable. The insulating sheath material for the silicone rubber cable comprises the following raw materials in percentages byweight: 0.3 to 0.5% of a vulcanizing agent, 0.1 to 0.3% of a crosslinking agent, 0.1 to 0.15% of a scorch retarder; 0.15 to 0.18% of an accelerator, 0.12 to 0.15% of an antioxidant, 0.12 to 0.15% of an anti-aging agent, 0.15 to 0.20% of a plasticizer, 0.10 to 0.15% of a stabilizer, 0.12 to 0.15% of a UV absorber and 0.15 to 0.20% of a lubricant, with the balance being methyl vinyl silicone rubber.The insulating sheath material for the silicone rubber cable provided by the invention is used as an insulating and sheathing material of a cable, is extruded to be coated outside a conductive wire core and a cable core, can enable the cable to meet the use need of a working temperature of about 250 DEG C, and has high popularization value.

Description

technical field [0001] The invention relates to the technical field of silicone rubber cables, in particular to an insulating sheath material for silicone rubber cables. Background technique [0002] At present, the maximum operating temperature of 1.8 / 3KV silicone rubber power cables with cross-linked polyethylene (or polyvinyl chloride) insulated sheath is only 90°C; while the actual working temperature of general 1.8 / 3KV silicone rubber power cables is 180°C ℃; and in some specific use occasions, the working temperature of the silicone rubber power cable is required to reach about 250 ℃. Obviously, the insulating sheath of the existing silicone rubber power cable cannot meet the requirements for use. Therefore, the present invention provides an insulating sheath material for silicone rubber cables, which can be used at a working temperature of 250°C. Contents of the invention [0003] The object of the present invention is to provide an insulating sheath material for ...
