Abstract

The invention discloses a high-temperature-resistant and oxidation-resistant cable insulation layer material. The high-temperature-resistant and oxidation-resistant cable insulation layer material is prepared from the following raw materials in parts by weight: 10-30 parts of PP resin, 5-15 parts of tetraphenyl ethylene, 3-13 parts of zinc oxide, 4-16 parts of lead monoxide, 6-18 parts of bakelite, 3-9 parts of pitch, 3-15 parts of sodium borate, 7-21 parts of conductive carbon black, 5-25 parts of argil, 1-9 parts of calcium carbonate, 2-14 parts of a stabilizer, 3-13 parts of an activating agent, 6-18 parts of a lubricating agent, and 2-10 parts of a coupling agent. The high-temperature-resistant and oxidation-resistant cable insulation layer material has the advantages of high temperature resistance, good oxidation resistance and long service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to a high-temperature-resistant and anti-oxidation cable insulating layer compounding. Background technique [0002] At present, the demand for cables in communication and other fields is increasing, so people's requirements for cables are getting higher and higher. People often install an insulating layer inside the cable to effectively prevent the leakage of the cable, and at the same time protect The internal structure of the cable, but the existing insulating layer has a single function due to improper selection of ingredients, and cannot withstand higher temperatures, which brings a lot of inconvenience to people's use. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a high temperature resistant and anti-oxidation cable insulation layer composition. [0004] The present invention is ...
