Abstract

The invention discloses a sheathing compound for a cable. The sheathing compound is prepared from the following raw materials in parts by weight: 50 to 70 parts of natural rubber, 20 to 30 parts of butadiene rubber, 5 to 15 parts of polybutylene terephthalate, 20 to 30 parts of carbon black N774, 3 to 5 parts of aluminum stearate, 3 to 6 parts of promotor CZ, 10 to 15 parts of para-tert-butyl phenolic resin, 4 to 8 parts of microcrystalline wax, 2 to 5 parts of anti-aging agent, 2 to 5 parts of N-cyclohexylthiophthalimide, 3 to 5 parts of aromatic hydrocarbon oil, 10 to 15 parts of aluminum hydroxide, 5 to 10 parts of zinc borate, 2 to 5 parts of tripolycyanamide, 4 to 8 parts of encapsulated red phosphorous, 6 to 10 parts of barium sulfate, 6 to 10 parts of nanometer aluminum oxide and 4 to 6 parts of composite filler. The sheathing compound disclosed by the invention has the advantages of excellent properties of heat resistance, wear resistance, ageing resistance, ultraviolet ray radiation resistance, oil resistance, acid-base resistance and the like, and is durable.

Description

technical field [0001] The invention relates to the field of cable sheaths, in particular to a sheathing material for cables. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. The existing wire and cable sheath materials are mostly made of synthetic rubber. Although synthetic rubber sheaths have excellent physical and mechanical properties, oil resistance, acid and alkali resistance, oil resistance, high and low temperature resistance, etc., currently synthetic rubber The sheath of the present invention has poor bending resistance and cannot meet the increasing market demand. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sheath material for cables, which has excellent comprehensive performanc...
