Cable insulation shell

[0018] Take 65kg PVC, 10kg barium zinc stabilizer, 10kg chlorinated paraffin, 5kg triethanolamine borate, 10kg calcium carbonate

[0019] In the high-speed mixer, heat and mix in the high-speed mixer for 20 minutes, the heating temperature is 80°C, and cool to 50°C; add 0.5kg polycarbazolyl (meth)acrylate, keep stirring at 50°C for 2 hours, in the open Plasticize on a double-roller plasticizing machine, the temperature of the double-rollers is 170°C, and the material is discharged after 10 minutes; then molded on a flat vulcanizer at 5MPa and 170°C for 5 minutes, the pressure is raised to 10MPa, and the pressure is kept constant, and hot-pressed for 5 minutes, that is Get the cable insulation jacket.

[0021] Take 60kg PVC, 8kg barium zinc stabilizer, 8kg chlorinated paraffin, 7kg triethanolamine borate, and 10kg calcium carbonate

[0022] In the high-speed mixer, heat and mix in the high-speed mixer for 25 minutes, the heating temperature is 80°C, and cool to 50°C; add 1kg of polycarbazolyl (meth)acrylate, keep stirring at 50°C for 1.5 hours, in the open double Plasticize on the roller plasticizing machine, the temperature of the twin rollers is 170°C, and the material is discharged after 10 minutes; then molded on the flat vulcanizer at 5MPa and 170°C for 5 minutes, the pressure is raised to 10MPa, keep the pressure constant, and hot press for 5 minutes to obtain Cable insulation jacket.

[0023] The cable insulation jackets obtained in Examples 1 and 2 all meet the standard requirements of GB / T5013-2008 after testing. In addition, the insulation jackets can continuously emit fluorescence visible to the naked eye when the illumination is 0.1 lx.
