Abstract

The invention relates to an environment-friendly high intensity high flame resistance cable prepared by utilizing tannery chromium-containing sludge. The cable sequentially comprises a core, an insulation layer, an internal protection layer and a sheath tube from inside to outside, wherein raw materials of the sheath tube comprise polyacrylonitrile / ethane / styrol copolymer, the tannery chromium-containing sludge, bentonite, methyl triethoxysilane, zinc oxide, sodium alginate, bisphenol fluorenes and hexaphenoxy cyclotriphosphazene. The cable has advantages of high flame resistance and high intensity and further has the low smog release effect.

Description

technical field [0001] The invention relates to a high-strength cable, in particular to an environment-friendly high-strength and high-flame-resistance cable prepared by utilizing chrome-containing sludge from tanning. 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, ...
