Abstract

The invention discloses a flame retardant polyethylene insulated cable material and relates to the technical field of cables. The flame retardant polyethylene insulated cable material is prepared from the following materials in parts by weight: 80 parts of polyethylene, 5 parts of aluminium oxide, 20-35 parts of magnesium hydroxide, and 1-5 parts of antiaging agent. According to the invention, the cable material has the performances of being hard to combust and being capable of preventing combustion, can reach the flame retardant level of V-0 level, cannot easily produce halogen-containing toxic substances in combustion, cannot easily produce smoke, and is applicable to high and low voltage power cables.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a flame-retardant polyethylene insulating cable material. Background technique [0002] In the long-term operation of power cables, it is easy to accumulate heat and cause fires. The main factor causing death in fires is not the direct combustion of flames, but the smoke generated when materials are burned. These smokes not only produce a large amount of toxic substances, but also can This is the main cause of death due to fire, and most of the existing power cable materials will produce a lot of smoke and toxic substances when burned, and these are mostly organic polymers, which are easy to burn, so in the event of a fire Fueled the fire, causing more damage. Contents of the invention [0003] The object of the present invention is to provide a low-smoke, halogen-free flame-retardant polyolefin cable material. [0004] In order to solve the existing problems in th...
