Problems solved by technology

This kind of luminescent cable can only play an indicator role when there is electricity. If there is no current flowing in the cable, no fluorescence will be generated; Falling off due to friction and other reasons shortens the validity period
Chinese patent application 200510038140.9 discloses a method of mixing photo-induced long-lasting luminescent materials in the rubber sheath of the cable, so that the cable can emit light in weak light, but the material used is strontium aluminate, and the amount used accounts for About 20% of the total weight, and the current price of strontium aluminate is as high as 100,000 yuan / ton, which undoubtedly greatly increases the cost of the product

Embodiment 1

[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.

Embodiment 2

[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.

Abstract

The invention provides a cable insulation shell, which can be revealed under illumination. The invention has the technical content that organic luminescent material poly-carbazolyl (methyl) acrylate is added in a common cable insulation shell.

Description

technical field [0001] The invention relates to a cable insulating sheath, in particular to a cable insulating sheath capable of being visible under specific light. Background technique [0002] In underground mines, tunnels, underwater and other dark environments, once a power outage occurs, it is difficult for maintenance personnel to determine the specific location of the cable, which brings great difficulties to the repair work. The luminescent high-voltage cable disclosed in Chinese patent 02213318.6 has an electro-excited phosphor layer attached to the surface of the insulating adhesive layer. The function is to excite the phosphor to emit light when the cable has a current passing through, and remind people of the position of the cable. This kind of luminescent cable can only play an indicator role when there is electricity. If there is no current flowing in the cable, no fluorescence will be generated; Friction and other reasons cause shedding, shortening the validi...
