Notification number is the utility model patent of CN203366804U, although it adopts the braided fabric layer that polyethylene fiber and non-woven fabric wrapping constitutes as non-metal reinforcement layer to improve load weight, it still has shortcoming, the first, the braided fabric is used as a whole The reinforcement layer is not used as an armor wire, which makes it inconvenient to use, and it is not convenient to adjust the layout of the armor layer according to the depth of the umbilical cable to achieve the required strength; second, the overall tensile strength of the reinforcement layer Strength and tensile modulus are not conducive to control; third, the adaptability to the environment such as temperature, chemical resistance, etc. is not strong; fourth, it is not convenient for production and assembly
The prior art also uses FRP and aramid fiber as the braided fabric layer, but its tensile strength and tensile modulus are relatively insufficient, and it is impossible to produce super-long armored wires, which is not conducive to use below 10,000 meters in deep sea

Embodiment 1

[0091] Raw materials used: ultra-high molecular weight polyethylene fiber is SK78 dtex1760 ASP produced by DSM in the United States, the impregnating resin is SS-25 polyurethane resin produced by Shanghai Sunshine Polymer Co., Ltd., and the coating material is nylon 6 material AKULONяF- produced by DSM X9190 PA6.

[0092] The aforementioned method is used to prepare the non-metallic armored wire, in which three stages of heating are used for heating and curing in the mold. The first stage is 80°C, the second stage is 120°C, and the third stage is 140°C. The pulling speed of the tractor It is 1m / min. The diameter of the inner core is 2.9 mm, and the ultra-high molecular weight polyethylene fiber accounts for 75% of the weight ratio of the inner core of the non-metallic armored wire. The experimental results are shown in Table 1, Table 2, Table 3, and Table 4.

Abstract

The invention relates to a non-metal armored wire. The inner core is formed by curing an ultra-high molecular weight polyethylene fiber impregnated with synthetic polyurethane resin. The outer layer is coated with a wear layer. The non-metal armored wire is suitable for being used by an umbilical cable of a full deep sea remote control submersible. The non-metal armored wire has the advantages ofhigh environmental adaptability, great tensile strength and tensile modulus performance, convenient use, high production efficiency, high cost performance and the like.

Description

technical field [0001] The invention relates to an armored wire for an umbilical cord, belonging to the technical field of composite optical cable materials. Background technique [0002] The umbilical cable is the key equipment for deep-sea energy development. It is responsible for the "signal" and "substance" communication between the underwater mining subsystem and the surface floating mother platform. It occupies a very important position in the process of underwater oil and gas development. Developed "nervous system" and "umbilical cord of life". [0003] With the continuous breakthrough of the maximum diving depth of Remotely Operated Vehicles (ROV), especially the 10,000-meter deep-sea ROV development project, the development of umbilical cables for deep-sea ROVs has become an urgent task for my country's deep-sea technology. However, the existing deep-sea ROV umbilical cables are metal-armored umbilical cables, and steel wires are used as the armoring material. Due ...
