Abstract

The invention discloses a low-smoke halogen-free flame-retardant cable material which is prepared from the following components in parts by weight: 100 parts of base resin, 80 parts of flame retardant, 0.2-4 parts of coupling agent, 1-4 parts of antioxidant, 5-20 parts of flame-retardant synergist, 2-10 parts of compatiblizing agent and 0.2-4 parts of lubricant. The invention also discloses a preparation method of the low-smoke halogen-free flame-retardant cable material. Due to the adoption of the technical scheme, especially the use of the flame-retardant synergist, the working properties and self-extinguishing property of the low-smoke halogen-free flame-retardant cable material are obviously enhanced. Under the action of the coupling agent and compatiblizing agent, the low-smoke halogen-free flame-retardant cable material has the advantages of favorable working properties, low smoke and favorable flame retardancy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-smoke halogen-free flame-retardant cable material and a preparation method thereof. Background technique [0002] The insulating materials and sheath materials widely used in wires and cables are mainly flammable polymer materials, which often cause combustion due to self-heating or external fires during the transmission of electric energy, posing serious safety hazards. Traditional flame-retardant cables are widely made of halogen-containing polymers and halogen-containing flame retardants (such as polybrominated diphenyl ethers, polybrominated biphenyls, etc.). Although these cables have good flame retardant properties, once a fire breaks out, the cables will produce a large amount of toxic smoke and corrosive gases after burning, hindering personal safety and delaying rescue work. [0003] Low-smoke, halogen-free flame-retardant materials do not produce harmfu...
