Problems solved by technology

[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 and caused more damage

Abstract

The invention discloses a halogen-free, low-smoke and flame-retardant cable material. The cable material is prepared from the following raw materials in parts by weight: 40-60 parts of high-density polyethylene, 30-50 parts of low-density polyethylene, 20-30 parts of butadiene rubber particles, sufficient hydrogen peroxide, 1-2 parts of a flame retardant and 2-4 parts of a reinforcing agent. The invention further discloses a processing technology of the halogen-free, low-smoke and flame-retardant cable material. Due to adoption of the technical scheme, the cable material has the following beneficial effects: the cable material is difficult to burn and can prevent burning, halogen-containing toxic substances and smoke cannot be produced easily during burning, and the cable material can alsobe applied to high and low voltage power cables.

Description

technical field [0001] The invention relates to the field of power cable production, in particular to a halogen-free low-smoke flame-retardant cable material and its processing technology. 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 technical problem to be solved by the present invention is to provide a halogen-free low-smoke flame-retardant cable material and its processing te...
