Problems solved by technology
[0002] At present, in the cable material industry, PVC and ordinary low-smoke and halogen-free use occupy a large proportion. However, since cables and cables are usually laid in closed spaces such as tunnels and walls, once a fire occurs, PVC will release a lot of smoke and toxic gases. , is the greatest threat to human life in a fire
The development of ordinary low-smoke and halogen-free has been greatly improved to a certain extent, but the mechanical and physical properties are unbalanced, and there are great limitations in use
In the actual production and daily use of the wire and cable materials, there are certain technical problems such as potential safety hazards.

The invention relates to a material for an electric wire and a cable, belonging to the technical field of electric wires and cables. The material for the electric wire and cable is characterized by comprising the following materials in parts by weight: 100-120 parts of EVA (ethylene-vinyl acetate), 18-24 parts of PE (poly Ethylene), 10-15 parts of ethylene propylene diene monomer rubber, 52-58 parts of POE (polyolefin elastomer), 7-10 parts of PPO (Polyphenylene Oxide), 0.6-0.9 part of silicone, 3-4 parts of TAIC (triallyl isocyanurate), 200-250 parts of magnesium hydrate, 8-12 parts of zinc borate and 28-32 parts of PE-g-MAH (polyethylene-grafted maleic anhydride). The material for the electric wire and the cable, disclosed by the invention, has the advantages of greenness and environmental friendliness, no dipping situation during combustion, small damage of toxic gas and smoke in fire, high flame retardance, excellent chemical corrosion resistance and electric performance, high mechanical physical property, good resistances to aging, oil and the like, good machining index and the like.
Description
technical field [0001] The invention belongs to the technical field of wires and cables, in particular to a material for wires and cables. Background technique [0002] At present, in the cable material industry, PVC and ordinary low-smoke and halogen-free use occupy a large proportion. However, since cables and cables are usually laid in closed spaces such as tunnels and walls, once a fire occurs, PVC will release a lot of smoke and toxic gases. , is the greatest threat to human life in fires. The development of ordinary low-smoke and halogen-free products has been greatly improved to a certain extent, but the imbalance of mechanical and physical properties has great limitations in use. When the wire and cable materials are used in actual production and daily life, there are certain technical problems such as potential safety hazards. Contents of the invention [0003] The invention provides a wire and cable material to solve the technical problems in the known technolo...
