Problems solved by technology

③ Unlike halogen flame retardants, phosphorus nitrogen flame retardants and other flame retardants that have a clear flame retardant mechanism, there is no systematic explanation for the mechanism of nano flame retardant at this stage
Therefore, the elaboration of the flame retardant mechanism of nanoparticles in the polymer combustion process will be the direction of future research. At the same time, due to the lack of polar functional groups on the surface of carbon nanotubes, the compatibility with the polymer matrix is ​​poor; the high aspect ratio The structure will lead to entanglemen

Abstract

The invention discloses a light flame-retardant optical cable material, which is composed of the following raw materials in parts by weight: 1 to 2 parts of polyvinylpyrrolidone, 3 to 5 parts of triethyl citrate, 0.1 to 0.2 part of N,N-diethyl aniline, 6 to 7 parts of guanidine sulfamate, 20 to 23 parts of carbon nanotube, 0.3 to 0.4 part of N,N'-dicyclohexyl carbimide, 4 to 5 parts of phosphonitrilic chloride trimer, 0.2 to 0.4 part of sodium hydroxide, 1 to 2 parts of thiourea, 17 to 20 parts of nylon, 120 to 130 parts of polyvinyl chloride, 1 to 2 parts of disodium hydrogen phosphate, 2 to 3 parts of glycerol triacetate, 3 to 4 parts of rosin alcohol, 4 to 5 parts of light calcium carbonate, 0.8 to 1 part of beta-hydroxyalkyl amide, and 0.7 to 1 part of polyvinyl butyral. The provided optical cable material is light and thus is convenient for installation and transportation.

Description

technical field [0001] The invention relates to the technical field of optical cable materials, in particular to a light-weight flame-retardant optical cable material and a preparation method thereof. Background technique [0002] Nanotechnology emerged in the 1980s and has been widely used in many fields. The study found that adding nanoparticles to polymers can greatly improve the performance of the material. For example, when a small amount of nanoparticles such as graphite calcium, carbon nanotubes, and molybdenum disulfide are added to the polymer, the mechanical strength of the material will significantly increase the IWI. The study found that adding only a very small amount of nanomaterials can greatly reduce the heat release rate of material combustion, and at the same time increase the mechanical strength of the composite material. At present, there are mainly several kinds of nano-flame retardant systems that have been studied more: (1) inorganic nanoparticles, s...
