Low-smoke halogen-free cable material

Abstract

The invention provides a low-smoke halogen-free cable material, and relates to the technical field of cables. The low-smoke halogen-free cable material is prepared from the following raw materials: 100 parts of polyethylene, 5 parts of silicon carbide, 10 to 20 parts of aluminum hydroxide, 5 to 20 parts of magnesium hydroxide and 2 to 4 parts of an anti-aging agent. The cable material provided by the invention has the following advantages: difficult combustion and resistance to combustion are achieved; the flame retardant rating of V-0 can be reached; and when in combustion, the cable material is not liable to generate halogen-containing toxic substances and smoke dust, and is suitable for being applied in high-low pressure power cables.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a low-smoke and halogen-free 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 invention is to provide a low-smoke, halogen-free cable material. [0004] In order to solve the existing problems in the background technology, the present invention a...
