NOVELTY - The preparation method of environmentally-friendly high-strength high flame retardant acrylonitrile-ethylene-styrene cable involves using 70-80 pts. wt. acrylonitrile/ethylene/styrene copolymer, 5-10 pts. wt. tannery sludge, 1-3 pts. wt. bentonite, 0.2-0.6 pt. wt. graphene, 0.8-1.2 pts. wt. octyl triethoxysilane, 2 pts. wt. stearic acid, 1-2 pts. wt. zinc oxide, 0.2-0.7 pt. wt. sodium alginate, 1-2.2 pts. wt. bisphenol fluorene, and 1.2-3.6 pts. wt. hexaphenoxy cyclotriphosphazene. USE - Preparation of environmentally-friendly high-strength high flame retardant acrylonitrile-ethylene-styrene cable (claimed). ADVANTAGE - The method enables the preparation of environmentally-friendly high-strength high flame retardant acrylonitrile-ethylene-styrene cable with high flame retardance and strength. DETAILED DESCRIPTION - The preparation method of environmentally-friendly high-strength high flame retardant acrylonitrile-ethylene-styrene cable involves (i) weighing 70-80 pts. wt. acrylonitrile/ethylene/styrene copolymer, 5-10 pts. wt. tannery sludge, 1-3 pts. wt. bentonite, 0.2-0.6 pt. wt. graphene, 0.8-1.2 pts. wt. octyl triethoxysilane, 2 pts. wt. stearic acid, 1-2 pts. wt. zinc oxide, 0.2-0.7 pt. wt. sodium alginate, 1-2.2 pts. wt. bisphenol fluorene, and 1.2-3.6 pts. wt. hexaphenoxy cyclotriphosphazene, mixing polyacrylonitrile/ethylene/styrene copolymer, tannery sludge, bentonite, graphene, octyl triethoxysilane, stearic acid, zinc oxide, sodium alginate, bisphenol fluorene, and hexaphenoxy cyclotriphosphazene in certain ratio, stirring at 600 rpm for 10 minutes, melt blending at 190 degrees C for 10 minutes to obtain plastic material, (ii) crosslinking the plastic material at 200 degrees C for 30 minutes, adding 3-5 pts. wt. gum arabic, and 0.8 pt. wt. white carbon black, reacting for 10 minutes to obtain mixture, (iii) adding mixture into a twin-screw extruder, extruding, and granulating to obtain pellet, (iv) adding pellet into an extrusion molding machine, molding, sizing, tractioning, and cutting to obtain sheath tube, (v) using sheath tube as an outermost layer of the cable. The cable comprises a core which is formed with a heat preservation layer, an inner sheath layer, and a sheath tube from inside to outside portions.
