Embodiment 1

[0056] Such as Figure 1 to Figure 3 Shown is a first embodiment of the anti-fouling and anti-adhesion high-strength polyester cable used in the deep sea of ​​the present invention. Such as figure 1 As shown, it includes a polyester rope body 1 and terminal eye rings 2 located at both ends of the polyester rope body 1. The terminal eye rings 2 are connected to both ends of the polyester rope body 1 by plug-in technology, which is convenient for connection when the cable is used. Such as figure 2 and image 3 As shown, the polyester rope body 1 includes an inner core 11, an anti-sand belt 12 and a braided overcoat 13. The inner core 11 is formed by arranging a plurality of 12-strand ropes in sequence. As an example, it can also be composed of more 12-strand sub-ropes, or more than 12 sub-ropes; the more the number of sub-ropes, the stronger the number of strands; the braided coat 13 is composed of many multi-strand strands Weaving, here weaving 48 4-strand strands with bra...

Embodiment 2

[0059] The present invention is a second embodiment of an anti-fouling and anti-adhesion high-strength polyester cable used in deep sea. Become, braided jacket 13 is woven by 60 8 strands strands.

no. 1 example

[0061] Such as Figure 4 Shown is a first embodiment of the preparation method of a polyester cable used in the deep sea according to the present invention, which specifically includes the following steps:

[0062] S1, making the inner core 11;

[0063] S11. Raw material wire drawing: Stir the raw material evenly and heat it to 250°C to melt it, and then extrude it from the spinneret to form a monofilament. Dry at 70°C and wind up for later use.

[0064] S12. Splicing to make single yarn; the single yarns are bundled into strips and hung on the grid, then pulled to the splicing machine, and the single yarn is twisted clockwise or counterclockwise by the splicing machine to form a single yarn. The single yarn is seawater-grade polyester yarn, and the performance of the single yarn is tested. Among them, during the splicing process, the tension meter on the splicing machine performs tension control to ensure that the minimum breaking load of the cable is 21437KN. In addition...

Abstract

The invention provides an anti-fouling and anti-adhesion high-strength polyester cable for deep and far seas and a preparation method thereof, and relates to the technical field of ship ocean engineering. The polyester cable comprises a polyester rope body and terminal eye rings, wherein the polyester rope body comprises an inner core, a sand-proof belt and a woven outer sleeve; the inner core is formed by sequentially arranging multiple 12-strand sub-ropes; the sand-proof belt is wound outside the inner core and located between the inner core and the woven outer sleeve; the woven outer sleeve is formed by weaving multiple multi-strand strands; and the woven outer sleeve is coated with an anti-fouling and anti-adhesion coating prepared by mixing a carbon nano tube and a chlorinated polyether resin anti-fouling agent. According to the anti-fouling and anti-adhesion high-strength polyester cable for deep and far seas and the preparation method thereof provided by the invention, the inner core is formed by sequentially arranging the multiple 12-strand sub-ropes, and the woven outer sleeve is formed by weaving the multiple multi-strand strands, so that the cable has very good chemical corrosion resistance and wear resistance. The sand-proof belt is wound outside the inner core, so that soil particles exceeding 5 microns can be effectively blocked. Through the anti-fouling and anti-adhesion coating, the combination degree of the coating and fibers can be improved, the flexibility of the cable is improved, and the anti-fouling performance of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of ship marine engineering, in particular to an anti-fouling and anti-adhesion high-strength polyester cable for deep seas and a preparation method thereof. Background technique [0002] With the advancement of science and technology, the focus of offshore oil and gas development is gradually shifting to sea areas with harsher natural environments such as deep water and polar regions. As one of the core technologies and equipment for the development and utilization of oil and gas resources, synthetic fiber cables that are lightweight, high-strength, easy to operate, and economical are essential mooring tools for deep-sea floating platforms and other marine engineering equipment. Pull, impact resistance, wear resistance, corrosion resistance, good flexibility and so on. However, due to the lack of super-long and super-strong mooring cables suitable for deep-water environments, as well as related large-scale ...
