Abstract

The invention discloses an environment-friendly power cable insulating material. The environment-friendly power cable insulating material is mainly prepared from, by weight, 15-20 parts of nano silicon dioxide, 15-25 parts of polyolefin, 10-15 parts of an organic silicon crosslinking agent, 10-15 parts of flame-retardant oil, 2-8 parts of a plasticizer, 25-35 parts of phenolic resin, 20-25 parts of polypropylene reinforced fibers, 15-25 parts of paraffin hydrocarbon oil, 2-8 parts of chitosan, 5-10 parts of polyolefin acid salt, 10-20 parts of a flexibilizer, 5-10 parts of silica powder, 20-30 parts of nano zinc oxide and 15-25 parts of polybutylene terephthalate. The environment-friendly power cable insulating material has advantages that the technical simplicity in preparation is realized, the preparation process is environment friendly and free of pollution, the prepared material guarantees efficacies of oxidation resistance, corrosion resistance, humidity resistance and flame retardation of power cables and improves elasticity and toughness of the power cables, and accordingly service lives of the power cables can be prolonged.

Description

technical field [0001] The invention relates to the field of insulating materials, in particular to an environment-friendly insulating material for power cables. Background technique [0002] Power cables are generally laid below the surface. Compared with overhead lines, because they are laid below the surface, they are less affected by the climate, safe, reliable, concealed and durable, but the cost of materials, laying costs, and maintenance costs are relatively high, and maintenance and Troubleshooting is also more difficult. Low-voltage distribution networks and electrical equipment wires and cables often use plastic sheathed wires with PVC sheaths as power transmission lines. These wires are generally buried in walls or under the ground through pipes. Sparks generated by poor insulation of wires often easily cause fires in factories, residences, public places, etc., causing casualties and property losses. Contents of the invention [0003] The purpose of the presen...
