Low-smoke halogen-free flame-retardant cable material

Abstract

The invention relates to a low-smoke halogen-free flame-retardant cable material. The low-smoke halogen-free flame-retardant cable material is characterized by comprising the following components in parts by weight: 100 parts of rubber-ethylene-acrylic rubber, 3-3.3 parts of peroxide arox, 0.8-1.0 part of co-vulcanization agents, 50-60 parts of calcined pottery clay+LEE white slippery powder, 12-14 parts of processing agents, 1.2-1.4 parts of zinc stearate and 43-47 parts of magnesium hydroxide, wherein the calcined pottery clay+LEE white slippery powder is processed through the zinc stearate. The low-smoke halogen-free flame-retardant cable material disclosed by the invention has the advantages of low toxicity, no halogen or harmful substances, namely sulfur, antimony, and the like, less environment pollution, and the like.

Description

technical field [0001] The invention relates to a cable material with improved flame retardancy, in particular to a low-smoke, halogen-free flame-retardant cable material Background technique [0002] With the rapid development of the national economy, wires and cables have become an indispensable material in various industries of the national economy, and are also the source of fire. In order to avoid the frequent occurrence of fires caused by cables, countries all over the world are competing to develop flame-retardant wire and cable products. For this reason, people have developed halogen-type flame retardants. The occurrence of fires has made wires and cables based on PVC and other materials popular among users. However, with the enhancement of people's awareness of environmental protection, it has been found that halogen-containing systems will produce a large amount of black smoke and acid mist during combustion, causing secondary pollution. Secondary pollution, the s...

In order to avoid the frequent occurrence of fires caused by cables, countries all over the world are competing to develop flame-retardant wire and cable products. For this reason, people have developed halogen-type flame retardants. The occurrence of fires has made wires and cables based on PVC and other materials popular among users. However, with the enhancement of people's awareness of environmental protection, it has been found that halogen-containing systems will produce a large amount of black smoke and acid mist during combustion, causing secondary pollution. Secondary pollution, the smoke is enough to suffocate people to death, so how to design halogen-free flame-retardant wire and cable products that meet low smoke, low toxicity, and low corrosion has become a top priority for the whole society
