Abstract

The invention discloses an intumescent flame-retardant cable material taking plant-based active carbon as a synergist and a preparation method thereof, and belongs to the technical field of flame-retardant high molecular materials. The cable material mainly comprises an EVM (Ethylene Vinyl Monomer), flame retardants, a flame-retardant synergist and a vulcanizing agent, and is prepared by adding the EVM into a mixing mill, plastifying, adding an aid, uniformly milling the mixture, blanking the milled mixture and vulcanizing the blanked mixture. In the halogen-free flame-retardant cable material, EVM rubber is taken as a substrate, so that the cable material has superior weather aging resistance, ozone resistance and heat resistance; meanwhile, ammonium polyphosphate and dipentaerythritol are taken as the flame retardants, and the plant-based active carbon is taken as the flame-retardant synergist, so that the material has the characteristics of superior flame resistance, low smoke, low toxicity, high charring property, environmental friendliness and the like, and the problem of high material density due to adding of a large quantity of inorganic flame retardants is solved; and the preparation method is simple, and is easy and convenient to operate.

Description

technical field [0001] The invention relates to an intumescent flame-retardant cable material with plant-based activated carbon as a synergist and a preparation method thereof, in particular to an intumescent flame-retardant cable with ethylene-vinyl acetate rubber as a matrix and plant-based activated carbon as a synergist A material and a preparation method belong to the technical field of flame-retardant polymer materials. Background technique [0002] With the progress of the world economy and the development of science and technology, all walks of life have higher requirements for cables and cable materials, and flame-retardant cable materials are one of the important development directions. Excellent flame-retardant cable materials can ensure the normal use of cables in the event of a fire, reduce fire hazards, and reduce economic and personnel losses. However, the existing materials for making cables are generally polyolefin polymer materials, which are flammable mat...
