Abstract

The invention relates to an environment-friendly high-strength and high flame-retardant cable sheath tube prepared from tanning chromium-containing sludge. The sheath tube is prepared from the following raw materials of polyacrylonitrile / ethylene / styrene copolymer, the tanning chromium-containing sludge, bentonite, methyl triethoxysilane, zinc oxide, sodium alginate, fluorene-9-bisphenol, and hexaphenoxy cyclotriphosphazene. The prepared cable has the advantages that the flame-retardant property and the strength are high, and the effect of low smoke release is realized.

Description

[0001] This application is a divisional application of the Chinese invention patent application filed on April 6, 2016 with the application number 201610209039.3 and the title of the invention is the use of tannery chromium-containing sludge to prepare environmentally friendly high-strength and high flame-retardant cables. technical field [0002] The invention relates to a high-strength cable, in particular to a sheath tube of an environment-friendly high-strength and high-flame-resistance cable prepared by utilizing chrome-containing sludge from leather making. [0003] technical background [0004] 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 cons...
