Abstract

An environment-friendly cable with high strength and high flame retardancy sequentially comprises a cable core, an insulating layer, an inner protecting layer and a sheath tube from inside to outside, wherein raw materials of the sheath tube comprise polyacrylonitrile / ethylene / styrene copolymers, chromium-containing sludge for tanning, bentonite, methyl triethoxysilane, stearic acid, zinc oxide, sodium alginate, bisphenol fluorine and hexaphenoxy cyclotriphosphazene. The prepared cable has high flame retardancy and strength and has the effect of low smoke release.

Description

technical field [0001] The invention relates to a high-strength cable, in particular to an environment-friendly high-strength and high flame-retardant cable. technical background [0002] With the gradual acceleration of the urbanization process, urban planning is becoming more and more modern. In the process of urban construction, cable entry into the ground has become the minimum construction requirement. At the same time, in the process of urban transformation, it is also necessary to put various cables erected in the air into the ground. At present, the construction of cables into the ground often adopts non-excavation technology. This construction method has the advantages of no impact on traffic, little damage to the stratum structure, and short cycle. , has the performance: the cable needs to have high strength, good rigidity and toughness, etc. In addition, due to the characteristics of the cable itself, it also needs to have the characteristics of high flame retar...
