Manufacturing process used for expanding optical fiber composite cable

The invention discloses a manufacturing process used for expanding an optical fiber composite cable. 100 parts of ultra-high molecular weight polyethylene resin, 20 to 35 parts of low-density polyethylene resin, 10 to 15 parts of polyether type TPU, 20 to 30 parts of poly(p-benzamide), 18 to 25 parts of epoxy butyl oleate, 15 to 25 parts of stearic acid and 10 to 15 parts of barium stearate are added into a high-speed mixer. The mixture is stirred at the speed of 500 to 800 rpm at 95 to 105 DEG C for 20 to 30 minutes. 8 to 12 parts of tributyl citrate, 6 to 10 parts of diatomaceous earth and 5to 10 parts of maleic anhydride grafted PE are fed into a twin-screw extruder. EVA is added. The temperature of the melting section of the extruder is controlled at 140 to 175 DEG C. Melt blending iscarried out at the rotation speed of 400 to 600r/min for 10 to 20 minutes. Pelleting is carried out through extrusion to acquire modified EVA particles. According to the invention, the aging test temperature of the thermoplas
