Abstract

The invention discloses an insulating material for a cable joint and a preparation method thereof. The insulating material is prepared from the following raw materials in parts by weight: 60-80 partsof epoxy resin, 25-35 parts of polyvinyl chloride, 15-25 parts of a curing agent, 15-20 parts of zeolite powder, 10-15 parts of silicone resin, 10-15 parts of a plasticizer, 8-14 parts of phenolic resin, 6-12 parts of asbestos powder, 6-12 parts of a preservative, 5-10 parts of cellulose, 4-9 parts of silicon carbide, 3-7 parts of a stabilizer, 2-5 parts of an additive and 1-3 parts of an antioxidant. The insulating material prepared by the method has good corrosion resistance, high-temperature resistance, good adhesive property and insulating property, good strength and toughness and low-temperature cold resistance, and the flame retardant property of the insulating material reaches V0 grade. The insulating material is quite low in manufacturing cost, and can meet the insulating demand onan existing cable joint.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to an insulating material used for cable joints and a preparation method thereof. Background technique [0002] Wires and cables are important materials for electric power and telecommunications. Cable fireproof coatings are suitable for flame retardant treatment of wires and cables in power plants, industrial and mining, telecommunications and civil buildings, and can also be used for combustible substrates in wood structures, metal structures and underground projects. Fire protection of other objects. The cable joint is connected in the middle or terminal of the cable, and connects the segmented cables into a whole connection device, which is used to lock and fix the incoming and outgoing lines, so as to keep the cable sealed and the line smooth, so as to ensure the normal operation of the cable. [0003] At present, the existing insulating materials used for cable jo...
