Description

Technical Field

[0001] The utility model relates to the technical field of fiber cables, in particular to an anti-water absorption fiber rope. Background Art

[0002] With the development and promotion of chemical fibers, fiber cables have been widely used in various fields. At present, fiber cables are already a very common auxiliary tool in mooring, industrial lifting, rock climbing, logging, aerospace and other fields.

[0003] Chemical fiber cables are made of several fibers through twisting, stranding and braiding. There will be certain gaps in the cable itself. When it is soaked in water, its weight will increase, and it can even increase by about 50%, which is not conducive to operation and use. At the same time, water absorption will change the original structure of the cable and affect the mechanical properties of the cable itself. Even if non-absorbent fibers are used, this phenomenon will still exist, and the weight of the cable will increase by 20-30%. A solution to the above problems is proposed below. Utility Model Content

[0004] The utility model aims to provide a water-proof fiber rope, which solves the problem that the existing chemical fiber ropes proposed in the above background technology lack waterproof performance, so that the weight of the fibers will increase when soaked in water, which is not conducive to operation.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A water-resistant fiber rope comprises a rope core, wherein the rope core comprises a plurality of rope strands, the rope core is woven by the plurality of rope strands, the rope strands can be made of any one of HMPE fiber, polyamide fiber, polyarylate fiber or polyester fiber, the outside of the rope core is provided with a water-repellent coating, and the outside of the rope core is wrapped with a braided sheath.

[0007] Preferably, the braided sheath comprises a plurality of rope strands 2 and a water-repellent coating 2, wherein the water-repellent coating 2 is coated on the outside of each rope strand 2, each rope strand 2 is braided on the outside of the rope core, and the material of the rope strand 2 is any one of HMPE fiber, polyamide fiber, polyarylate fiber or polyester fiber.

[0008] Preferably, the water-repellent coating accounts for 3%-5% of the mass of the rope core.

[0009] Preferably, the first water-repellent coating and the second water-repellent coating are any one of polyacrylate or water-based modified aliphatic polyurethane methyl ester.

[0010] Preferably, the mass ratio of the coating material of the water-repellent coating 1 to water is 1:2.5 to 1:5.

[0011] Preferably, the second water-repellent coating accounts for 5%-10% of the mass of the braided sheath.

[0012] Preferably, the mass ratio of the coating material of the second water-repellent coating to water is 1:1.5 to 1:3.

[0013] Preferably, the braided sheath structure is 3×24 strands or 4×24 strands, and the braiding pitch of the braided sheath is 4-5 times the diameter of the fiber rope.

[0014] Beneficial effects: By providing a water-repellent coating 1 on the outside of the rope core and applying a water-repellent coating 2 on the outside of the braided sheath, the waterproof performance of the rope is significantly improved, which helps prevent the rope from increasing in weight when immersed in water, thereby maintaining its convenience in operation and use; by reducing the water absorption of the rope in water, the weight increase during operation is reduced, making the rope easier to operate and use, and improving work efficiency.

[0018] See Figures 1 to 2 As shown, an anti-water absorption fiber rope includes a rope core 1, the rope core 1 includes a plurality of rope strands 2, the rope core 1 is woven by the plurality of rope strands 2, the rope strands 2 can be made of any one of HMPE fiber, polyamide fiber, polyarylate fiber or polyester fiber. In actual use, HMPE fiber can be selected. While ensuring the strength of the rope, materials with poor water absorption are selected to improve the waterproof performance of the rope.

[0019] The outside of the rope core 1 is provided with a water-repellent coating 3, which accounts for 3%-5% of the mass of the rope core 1. The material of the water-repellent coating 3 can be any one of polyacrylate or water-based modified aliphatic polyurethane methyl ester. The mass ratio of the coating of the water-repellent coating 3 to water is 1:2.5-1:5. By coating the water-repellent coating 3 on the outside of the rope core 1, the water-repellent coating 3 can be used to improve the waterproof performance of the rope, which helps to reduce the weight increase of the rope when it is immersed in water.

[0020] The outside of the rope core 1 is wrapped with a braided sheath 4. By weaving the braided sheath 4 on the outside of the rope core 1, the strength of the rope core 1 can be improved. The braided sheath 4 includes a plurality of rope strands 5 and a water-repellent coating 6. The water-repellent coating 6 is coated on the outside of each rope strand 5. Each rope strand 5 is braided on the outside of the rope core 1. The material of the rope strand 5 is any one of HMPE fiber, polyamide fiber, polyarylate fiber or polyester fiber. The structure of the braided sheath 4 is 3×24 strands or 4×24 strands, and the braiding pitch of the braided sheath 4 is 4-5 times the diameter of the fiber rope.

[0021] The water-repellent coating 26 can be made of any one of polyacrylate or water-based modified aliphatic polyurethane methyl ester. The water-repellent coating 26 accounts for 5%-10% of the mass of the braided sheath 4. The mass ratio of the coating of the water-repellent coating 26 to water is 1:1.5~1:3. The waterproof performance of the rope can be further improved by coating the braided sheath 4 with the water-repellent coating 26. The water-repellent coating 26 is coated on the outside of each rope strand 25, so that each rope strand 25 has good waterproof performance. When the braided sheath 4 fails due to wear and tear after long-term use, the waterproof performance of the entire braided sheath will not fail. The rope strands 25 where the water-repellent coating 26 has not failed can also play a waterproof effect, which improves the water repellency of the braided sheath 4. The water-repellent coating 26 plays the role of the first layer of protection. When the water-repellent coating 26 fails after long-term use, it can be further waterproofed through the internal water-repellent coating 3.

[0022] Through the layered design of the rope core 1, the water-repellent coating 1 3, the braided sheath 4 and the water-repellent coating 2 6, the lack of waterproofness of the existing cable is compensated, the water absorption of the rope in water is reduced, the weight increase during operation is reduced, the rope is easier to operate and use, and the work efficiency is improved.

[0023] In order to test the waterproofness of the ropes coated with water-repellent coating 1 and water-repellent coating 2, the performance of the ropes was tested (Material of rope strand 1: HMPE fiber Material of rope strand 2: HMPE fiber Specification: φ12mm)

[0024] Testing the waterproof performance of ropes

[0025]

[0026] Conclusion: Under the same conditions, the water repellency of ropes coated with water-repellent coating 1 and water-repellent coating 2 is greatly improved compared with uncoated ropes. This can effectively solve the problem of weight gain of chemical fiber cables due to their own structural gaps or fiber water absorption, ensure that the mechanical properties of the cables are not affected, and facilitate operation.
