Abstract

The invention discloses a halogen-free flame-retardant wire cable material which comprises the following components in parts by weight: 100 parts of polyphenylether resin, 5-15 parts of EVA (ethylene-vinyl acetate), 10-30 parts of PPO (polypropylene oxide), 20-40 parts of phosphorus-containing flame retardant, 5-15 parts of anti-aging agent and 60-80 parts of crosslinking agent. Certain amounts of three of the base materials are blended under the synergistic actions to obtain the halogen-free flame-retardant wire cable material with excellent mechanical property, excellent electric properties, favorable softness and outstanding flame retardancy.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant wire and cable material. Background technique [0002] In order to suppress or reduce fire accidents caused by the burning of wires and cables, halogen-containing flame retardants are usually used to improve the flame retardancy level of wires and cables. However, halogen-containing flame retardants will release a large amount of toxic, harmful and corrosive gases during the combustion process, which will have a serious impact on the environment and also cause harm to the health of firefighters. In view of this, most of the flame-retardant wire and cable materials in the prior art use polyolefin materials, and polyolefin materials need to add a large amount of flame retardants such as aluminum hydroxide and / or magnesium hydroxide to achieve the purpose of flame retardancy , Since materials such as aluminum hydroxide and / or magnesium hydroxide are inorganic mineral materials, the binding force bet...
