Embodiment 1

[0046] like figure 1 , 2 Shown: a deep-diving pressure-resistant and waterproof cable, including a flexible cable core 1, an insulated wire core 2, an inner sheath layer 3, a braided reinforcement layer 4 and an outer sheath layer 5. No less than four insulated wire cores 2 are evenly distributed around the flexible cable core 1, twisted into a strand to surround the flexible cable core 1; the inner sheath layer 3 is filled and adhered to the outside of the insulated wire core 2; braided reinforcement layer 4 gaps are wrapped around the outside of the inner sheath layer 3 , and the outer sheath layer 5 is overlapped and wrapped around the outside of the braided reinforcement layer 4 .

[0047] The flexible cable core 1 is composed of an aramid rope 11 and a flexible adhesive layer 12 extruded outside the aramid rope 11 . The flexible adhesive layer 72 is made of silicone rubber.

[0048] The insulated core 2 is composed of a conductor 21 , an inner insulating layer 22 wrap...

Embodiment 2

[0052] Compared with Example 1, this embodiment differs in that the material formulation of the inner sheath layer 3 and the outer sheath layer 5 is as follows: 100 parts of chlorinated polyethylene rubber, 15 parts of ethylene-butylene copolymer, ethylene-vinyl acetate 3 parts of grease rubber EVA, 10 parts of magnesium oxide, 3 parts of calcium zinc stabilizer, 2 parts of antiaging agent, 0.8 part of stearic acid, 9 parts of antimony trioxide, 2.5 parts of semi-refined paraffin, 22 parts of pigment carbon black, precipitation white 27 parts of carbon black, 50 parts of activated nano kaolin, 18 parts of flame retardant, 19 parts of talcum powder, 18 parts of dioctyl sebacate DOS, 6 parts of co-crosslinking agent, 5 parts of peroxide crosslinking agent.

[0053] The antiaging agent includes 1.0 parts of antiaging agent RD and 1.0 part of antiaging agent MB.

[0054] The beneficial effects brought by this formula are as follows: During the refining process, add chlorinated pol...

Abstract

The invention provides a deep submersion pressure-resistant waterproof cable comprising a flexible cable core, insulting wire cores, an internal sheath layer, a braided reinforcing layer and an external sheath layer. There are at least four insulating wire cores which are evenly distributed around the flexible cable core so as to form a strand through twisting to enclose the flexible cable core. The internal sheath layer fills and adheres the external part of the insulating wire cores. The braided reinforcing layer open wraps the external part of the internal sheath layer. The external sheath layer wraps the external part of the braided reinforcing layer. The advantages of the deep submersion pressure-resistant waterproof cable are that the cable is compact in integral structure and stable in performance. The integral structure of the cable is formed, and force can be evenly dispersed when the cable bears deep seawater pressure, pull force of the cable and external pull force so that damage to the external sheath layer caused by force bearing can be effectively reduced, and the phenomenon of "snakeskin" of the sheath layer can be effectively prevented.

Description

technical field [0001] The invention relates to a cable and a preparation method thereof, in particular to a deep submersible pressure-resistant waterproof cable and a preparation method thereof. Background technique [0002] The deep submersible waterproof cable used for moving the offshore working platform is placed in the deep sea, and it has to bear great water pressure, and there is still a certain range of swings in its working state. Therefore, it is resistant to water pressure, corrosion resistance, tensile resistance, bending resistance and Higher requirements for anti-fatigue performance. [0003] At present, the water pressure resistance, corrosion resistance, tensile resistance, bending resistance and fatigue resistance of existing waterproof cables are not ideal when used in deep sea. When swaying, it is prone to rupture due to excessive deep water pressure and rupture due to seawater corrosion of the sheath layer. At the same time, there is a phenomenon of cor...
