Problems solved by technology
The surface of TPE foam sheathed cable is rough, the mechanical properties of the sheath are poor, and the running resistance in water is relatively large; the cable with TPE foam sheath and TPU solid sheath, although the mechanical strength of the sheath is improved, the running resistance in water is reduced, but due to The TPE foam layer and the TPU layer of the solid sheath are two materials with a large difference in polarity. The two layers are layered, and the two layers of the sheath are easy to slip relative to each other, and it is easy to form air pockets when bending.
There is currently no foamable polyurethane on the market that satisfies a stable foundation

Embodiment Construction
[0028] The present invention is described further below:
[0029] The first aspect of this part introduces specific solutions:
[0030] floating cables, including
[0031] Inner cable 10, including wrapping in turn from inside to outside
[0032] core cable,
[0033] Tensile fiber layer 100; and
[0034] The sheath 20 is wrapped around the inner cable 10, including the sheaths that are wrapped sequentially from the inside to the outside.
[0035] TPU inner sheath layer 200,
[0036] TPU outer sheath layer 300;
[0037] Wherein, the TPU inner sheath layer 200 is foamed polyurethane, and the TPU outer sheath layer 300 is solid polyurethane. The polyurethane foam layer (TPU inner sheath layer 200 ) and the solid polyurethane reinforcement layer (TPU outer sheath layer 300 ) form an inseparable whole through molecular bonds.
[0038] The following are options in some examples,
[0039] The foamed polyurethane is composed of 62%-80% of TPU particles, 18%-30% of ethylene a...

Abstract
The invention relates to a floating cable which comprises an inner cable and a sheath, wherein the inner cable comprises an inner core cable and a tensile fiber layer which are sequentially lapped from inside to outside; the sheath is wrapped outside the inner cable and comprises a TPU inner sheath layer and a TPU outer sheath layer which are sequentially wrapped from inside to outside; and the TPU inner sheath layer is made of foaming polyurethane, and the TPU outer sheath layer is made of solid polyurethane. According to the TPU foaming layer and the solid TPU layer, the overall density of the cable is reduced, meanwhile, the overall mechanical strength, flatness and smoothness of the cable sheath are guaranteed, the running resistance when underwater equipment is dragged is effectively reduced, and firmness and safety of connection between the underwater equipment and a parent body are guaranteed.
Description
technical field [0001] The invention belongs to the technical field of cables, in particular to floating cables. Background technique [0002] At present, the types of floating cables include TPE foam sheath cables, TPE foam plus TPU solid sheath cables, and the structure of this cable is TPU foam plus TPU solid sheath. The surface of TPE foam sheathed cable is rough, the mechanical properties of the sheath are poor, and the running resistance in water is relatively large; the cable with TPE foam sheath and TPU solid sheath, although the mechanical strength of the sheath is improved, the running resistance in water is reduced, but due to The TPE foam layer and the TPU layer of the solid sheath are two materials with a large difference in polarity. The two layers are layered, and the two layers of sheath are easy to slip relative to each other, and it is easy to form air pockets when bent. There is currently no foamable polyurethane on the market that satisfies a stable base...
