Description

Technical Field

[0001] This utility model relates to the field of marine cable technology, and in particular to a high-performance flame-retardant and heat-insulating fire-resistant marine cable. Background Technology

[0002] In offshore operations, cables serve as crucial connection and traction tools, and their performance plays a key role in the safety and stability of the operation. However, the marine environment is complex and changeable, and cables may face dangers such as fires.

[0003] Existing marine cables are inadequate in terms of flame retardancy, heat insulation, and fire resistance. In the event of a fire, the cables are easily ignited, and the heat is transferred rapidly, causing the cable strength to decrease. This can not only damage equipment but also threaten the lives of offshore workers. In addition, the internal structure of ordinary cables is damaged in high-temperature environments, affecting their service life and performance. At the same time, offshore operations also face problems such as static electricity accumulation, marine organism attachment, and seawater corrosion, which further reduce the reliability and service life of the cables. Therefore, we propose a high-performance flame-retardant and heat-insulating fire-resistant marine cable to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-performance flame-retardant and heat-insulating fire-resistant marine cable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-performance flame-retardant and heat-insulating fire-resistant marine cable includes a core assembly, a flame-retardant and heat-insulating assembly, a protective assembly, and an abrasion-resistant outer layer. The flame-retardant and heat-insulating assembly is disposed outside the core assembly, the protective assembly is disposed outside the flame-retardant and heat-insulating assembly, and the abrasion-resistant outer layer is disposed outside the protective assembly. The core assembly includes a reinforcing core and multiple strands of cable core, with the multiple strands wound around the reinforcing core. The flame-retardant and heat-insulating assembly includes a heat-insulating layer and a flame-retardant layer. The heat-insulating layer is sleeved on the outside of the core assembly, and the flame-retardant layer is disposed outside the heat-insulating layer. The protective assembly includes a protective buffer layer, an antistatic layer, and an anti-biofouling layer. The protective buffer layer is sleeved on the outside of the flame-retardant layer, the antistatic layer is disposed outside the protective buffer layer, and the anti-biofouling layer is disposed outside the antistatic layer.

[0006] Preferably, the cable core is made of multiple strands of high-strength fiber filaments twisted together, and the high-strength fiber filaments are aramid fibers, with each high-strength fiber filament having a diameter of 0.1-0.3 mm.

[0007] Preferably, the heat insulation layer is made of ceramic fiber felt and aerogel composite, and the thickness of the heat insulation layer is 1-3mm.

[0008] Preferably, the flame retardant layer is coated with an intumescent flame retardant coating, and the coating thickness of the flame retardant layer is 0.5-1.5 mm.

[0009] Preferably, the protective buffer layer is made of polyurethane elastomer material, and the antistatic layer is woven from a mixture of conductive fibers and polymer materials.

[0010] Preferably, the anti-biofouling layer is made of an organosilicon coating material containing an antifouling agent.

[0011] Preferably, it also includes a moisture-proof layer, which is made of polyester film and has a thickness of 0.4-0.6 mm.

[0012] Preferably, the wear-resistant outer layer is woven from ultra-high molecular weight polyethylene.

[0013] The beneficial effects of this utility model are: 1. By setting up a multi-layer structure, the cable has high-performance flame retardant, heat insulation and fire resistance properties. In the event of a fire, the flame retardant layer can effectively prevent the spread of flames, the heat insulation layer can prevent heat from being transferred to the cable core, and the protective buffer layer can protect the internal structure from external impacts, ensuring that the cable can still maintain a certain strength and performance in fire and complex external force environments, which greatly improves the safety of offshore operations. 2. The cable core is made of aramid fiber and a reinforcing core, giving the cable high strength and high modulus, meeting the tensile strength requirements of offshore operations. The wear-resistant outer layer uses ultra-high molecular weight polyethylene, which enhances the cable's wear resistance and corrosion resistance. The antistatic layer solves the problem of static electricity accumulation, and the anti-biofouling layer inhibits the attachment of marine organisms. These designs enable the cable to better adapt to the complex and harsh marine environment, significantly extending the cable's service life and reducing operating costs. Attached Figure Description

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses a high-performance flame-retardant and heat-insulating fire-resistant marine cable.

[0018] Reference Figure 1-4 A high-performance flame-retardant and heat-insulating fire-resistant marine cable includes a core assembly 1, a flame-retardant and heat-insulating assembly 2, a protective assembly 3, and an abrasion-resistant outer layer 4. The flame-retardant and heat-insulating assembly 2 is disposed on the outside of the core assembly 1, the protective assembly 3 is disposed on the outside of the flame-retardant and heat-insulating assembly 2, and the abrasion-resistant outer layer 4 is disposed on the outside of the protective assembly 3. The core assembly 1 includes a reinforcing core 101 and multiple strands of core 102, with the multiple strands of core 102 wound around the reinforcing core 101. The flame-retardant and heat-insulating assembly 2 includes a heat-insulating layer 201 and a flame-retardant layer 202. The heat-insulating layer 201 is sleeved on the outside of the core assembly 1, and the flame-retardant layer 202 is disposed on the outside of the heat-insulating layer 201. The protective assembly 3 includes a protective buffer layer 301, an antistatic layer 302, and an anti-biofouling layer 303. The protective buffer layer 301 is sleeved on the outside of the flame-retardant layer 202, the antistatic layer 302 is disposed on the outside of the protective buffer layer 301, and the anti-biofouling layer 303 is disposed on the outside of the antistatic layer 302.

[0019] In this embodiment, the cable core 102 is made of multiple strands of high-strength fiber filaments twisted together, and the high-strength fiber filaments are set as aramid fibers 103. The diameter of each high-strength fiber filament is 0.1-0.3mm. Aramid fibers 103 have the characteristics of high strength and high modulus, which can provide strong tensile strength for the cable and ensure that the cable is not easily broken during the traction and connection process in marine operations. The multiple strands of high-strength fiber filaments are twisted together with a specific twist, the twist range is 10-20 twists / 10cm, which makes the cable core 102 structure compact and further improves the overall strength of the cable.

[0020] In this embodiment, the heat insulation layer 201 is made of ceramic fiber felt and aerogel composite. The thickness of the heat insulation layer 201 is 1-3mm. The ceramic fiber felt has good high temperature resistance and flame retardant properties, and the aerogel has an extremely low thermal conductivity, which can effectively prevent heat transfer.

[0021] In this embodiment, the flame retardant layer 202 is coated with an intumescent flame retardant coating. The coating thickness of the flame retardant layer 202 is 0.5-1.5mm. When exposed to high temperature, the intumescent flame retardant coating will expand rapidly to form a dense carbonized foam layer. This foam layer can isolate oxygen and heat, prevent the spread of flame, and play a good flame retardant role.

[0022] In this embodiment, the protective buffer layer 301 is made of polyurethane elastomer material. Polyurethane elastomer has good elasticity and buffering performance. When the cable is impacted by external force, the protective buffer layer 301 can effectively absorb the impact force and reduce damage to the internal structure. At the same time, it can also prevent sharp objects from piercing the flame retardant layer 202 and the heat insulation layer 201, further protecting the cable core 102. The antistatic layer 302 is woven from a mixture of conductive fibers and polymer materials. The conductive fibers can conduct away the static electricity generated by the cable during use in a timely manner, avoiding safety hazards caused by static electricity accumulation, such as fire caused by static sparks.

[0023] In this embodiment, the antifouling layer 303 is coated with an organosilicon coating material containing an antifouling agent. The antifouling agent can effectively inhibit the attachment and growth of marine organisms on the surface of the cable, reduce cable corrosion and performance degradation caused by biofouling, and extend the service life of the cable.

[0024] In this embodiment, the moisture-proof layer 104 is made of polyester film, and the thickness of the moisture-proof layer 104 is set to 0.4-0.6mm, which can prevent seawater and moisture from entering the cable core 102 and ensure the stability of the cable performance.

[0025] In this embodiment, the wear-resistant outer layer 4 is woven from ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene has excellent wear resistance and corrosion resistance, which can resist the wear and corrosion of the cable in the complex marine environment and extend the service life of the cable.

[0026] In this invention, by setting up a multi-layer structure, the cable possesses high-performance flame-retardant, heat-insulating, and fire-resistant properties. In the event of a fire, the flame-retardant layer 202 can effectively prevent the spread of flames, the heat-insulating layer 201 can prevent heat transfer to the cable core 102, and the protective buffer layer 301 can protect the internal structure from external impacts, ensuring that the cable can maintain a certain strength and performance under fire and complex external force environments, greatly improving the safety of offshore operations. The cable core 102 uses aramid fiber 103 and a reinforcing core 101, giving the cable high strength and high modulus characteristics, meeting the tensile strength requirements of offshore operations. The wear-resistant outer layer 4 uses ultra-high molecular weight polyethylene, enhancing the cable's wear resistance and corrosion resistance. The antistatic layer 302 solves the problem of static electricity accumulation, and the anti-biofouling layer 303 inhibits the attachment of marine organisms. These designs enable the cable to better adapt to the complex and harsh marine environment, significantly extending the cable's service life and reducing operating costs.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
