Abstract

The invention provides an efficient insulated cable material and a preparation method thereof, and relates to the technical field of cable production. The cable material is prepared from the raw materials in parts by weight: 45-55 parts of ethylene propylene diene monomer rubber, 15-20 parts of silicone rubber, 10-15 parts of polyurethane rubber, 4-6 parts of phenolic resin, 0.8-1.2 parts of polyvinyl chloride, 0.5-0.8 part of a modifier, 5-7 parts of polyalkylene glycol, 2-4 parts of polydiphenyl ether, 4-6 parts of m-xylylenediamine, 3-5 parts of shell-lac, 6-8 parts of sulfur hexafluoride,3-5 parts of ammonium phosphate, 5-7 parts of sulphur, 2-4 parts of boron nitride, 2-4 parts of a curing agent and 2-4 parts of a vulcanizing agent. According to the efficient insulated cable material, the shortcomings in the prior art are overcome, the insulation performance of the cable material can be effectively improved, the electricity is prevented from being transmitted to the outside to cause the risk of electric shock to a user when the cable is electrified, the insulation performance of the cable material is good, the flame resistance of the cable material can further be improved, the overall performance of the cable material is excellent, the safety is high, and the efficient insulated cable material is suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a high-efficiency insulating cable 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. As a supporting industry of the power industry, one of the pillar industries of the national economy, the wire and cable industry plays an extremely important role and position in the national economy. [0003] Since cables are mainly used for power transmission, the performance of the cables is extremely important. At present, the insulation performance of cable materials is poor. When the cable is energized, it is very easy to transmit electricity to the outside world, and the user is pr...
