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 raw materials in parts by weight: 80 parts of polyethylene, 5 parts of aluminum oxide, 20-35 parts of magnesium hydroxide and 1-5 parts of an anti-aging agent. According to the invention, the flame-retardant polyethylene insulated cable material is unlikely to combust and can prevent combustion, has a flame retardant rating of V-0, is not liable to produce halogen-containing toxic substances or smoke dust when the cable material is combusted, and is applicable to high and low voltage power cables.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular 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, and the main cause of death in fires is not the direct combustion of the flame, but the smoke generated when the material is burned. These smoke 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 they are 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. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a flame retardant polyethylene insulating cable material. [0004] In order to solve the problems existing in the background...
