Problems solved by technology

[0005] Another method is to solve the problem by increasing the extrusion thickness of the luminous layer, but limited by the production cost or design size requirements, the luminous layer cannot be too thick, resulting in insufficient luminous intensity and short luminous duration, which cannot meet the requirements of darkness. Requirements for at least 12 hours of glow time in

Embodiment 1

[0017] (1) Wire drawing and annealing the round metal wires to be twisted separately to make conductors, coat the conductors with an insulating layer, and extrude a water-blocking tape outside the insulating layer to form an insulated wire core, and multiple insulated wire cores are twisted with each other to form an insulated wire The core group: wrapping the tape on the outer periphery of the insulated wire core group and filling the gaps between the insulated wire cores.

[0018] (2) Prepare a flame-retardant layer, heat the flame-retardant material to melt, and then cool to obtain a flame-retardant layer, and wrap the prepared flame-retardant layer on the outer periphery of the tape.

[0019] (3) Prepare the shielding layer: equip the shielding layer material, and wrap the shielding layer material on the outside of the flame retardant layer by extrusion molding.

[0020] (4) Prepare the inner liner, and wrap the inner liner around the outer periphery of the shielding layer...

Abstract

The invention discloses a production method of a light-emitting cable, which comprises a step of extruding a light-emitting layer and a step of cooling the light-emitting layer. An atomization coolingstep is carried out between the step of extruding the light-emitting layer and the step of cooling the light-emitting layer. The cable with the extruded light-emitting layer passes through an atomization environment, and the diameter of atomization particles in the atomization environment is 0.25-0.5mum. According to the invention, the thickness of the light-emitting layer does not need to be increased, and the design size requirement of the cable can be guaranteed. The production cost of the cable can be reduced, and the surface of the light-emitting layer is roughened uniformly and finely after roughening treatment. The uniformity of the thickness of the light-emitting layer is guaranteed, and the light receiving capacity of the light-emitting layer is enhanced. The light-emitting intensity and the light-emitting time of the light-emitting layer are improved.

Description

technical field [0001] The invention relates to a production method of a cable, in particular to a production method of a luminous cable, and belongs to the technical field of cable production. The cables of the present invention include electric wires and cables, and are also applicable to optical cables. Background technique [0002] Luminescent cables are often used in places with narrow spaces, insufficient light, and harsh environments, such as mines, tunnels, bridges, and inside equipment. The use of luminous cables in these environments can be easily identified no matter in day or night, which greatly facilitates the inspection, construction, maintenance and repair of cables. [0003] At present, the commonly used light-emitting cables on the market mainly use a layer of light-emitting layer with light-emitting function on the outside of the cable or a layer of light-emitting material outside the cable, and then a layer of transparent material on the surface of the l...
