Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rope cable, concretely relates to a marine rope cable of biological adhesion prevention and antibiosis. BACKGROUND

[0002] Technora is a hybrid aromatic polyamide synthesized from terephthaloyl chloride and 3,4'-diaminodiphenyl ether (or similar structure), containing a combination of para and meta positions in its structure. Technora rope cable has been widely used in many harsh application environments due to its high strength, fatigue resistance, chemical corrosion resistance and high temperature resistance, such as marine cables, rescue ropes, sling cables, etc. However, with the passage of time, especially in marine environments or other high humidity environments, the surface of the rope cable is prone to microbial attack, such as the attachment and growth of bacteria and algae. This not only leads to a decrease in the antifouling performance of the rope cable, but also accelerates its aging and reduces its mechanical properties, thereby affecting the service life and safety of the rope cable. Therefore, how to enhance the antibacterial and antifouling performance of Technora rope cable and prolong its service life is an important problem in the current technical field. SUMMARY

[0003] To solve the above problems, the utility model aims at providing a marine rope cable of biological adhesion prevention and antibiosis, which can improve the antibacterial and antifouling performance of Technora rope cable and reduce the formation of biological adhesion and biological fouling.

[0004] The utility model realizes the following technical scheme:

[0005] A marine rope cable of biological adhesion prevention and antibiosis, comprising a core layer and a surface layer, the core layer is provided with a plurality of strands of aramid fiber and a plurality of strands of antibacterial polyvinyl chloride fiber, the plurality of strands of aramid fiber and the plurality of strands of antibacterial polyvinyl chloride fiber are twisted into a rope core, the surface layer is a corrosion-resistant layer, and the surface layer is coated with nano zinc oxide particles and / or cellulose nanocrystal particles.

[0006] The corrosion-resistant layer is a polyvinyl chloride layer or a polyethylene layer.

[0007] The utility model sets the surface layer as a polyvinyl chloride layer coated with nano zinc oxide particles and / or cellulose nanocrystal particles, the nano zinc oxide particles have antibacterial properties, and the addition of cellulose nanocrystals can appropriately increase the surface roughness and reduce the water contact angle, thereby preventing biological adhesion and the formation of biological fouling. Polyvinyl chloride or polyethylene has excellent corrosion resistance and chemical resistance, making it very suitable for marine environments.

[0008] A copper wire is further arranged at the center of the core layer, and the plurality of strands of aramid fiber and the plurality of strands of antibacterial polyvinyl chloride fiber wrap the copper wire and are twisted into a rope core. The copper wire and the antibacterial polyvinyl chloride fiber can synergistically prevent bacteria from growing in the core layer, thereby preventing the core layer fibers from being damaged by bacteria.

[0009] A rubber layer is also arranged between the core layer and the surface layer. The rubber layer is arranged to prevent seawater from wetting the core layer.

[0010] An ultraviolet protection layer is also arranged outside the surface layer. Although aramid 3 has excellent mechanical properties, its ultraviolet resistance is relatively weak. Long-term exposure to strong ultraviolet radiation can cause material aging and performance degradation. Therefore, an additional ultraviolet protection layer is arranged outside the surface layer. In implementation, a method of coating the surface layer with nano titanium dioxide particles can be used.

[0011] In implementation, the number of aramid fiber strands can be 3, and the number of antibacterial polyvinyl chloride fiber strands can be 3.

[0012] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0013] The utility model has excellent corrosion resistance and chemical resistance, can improve the antibacterial and antifouling performance of aramid rope cable, reduce the formation of biological adhesion and biological fouling, is very suitable for marine environment, and service life is prolonged.
