Description

Technical Field

[0001] This utility model relates to the field of fishing net line technology, and in particular to a fishing net line with anti-aging function. Background Technology

[0002] Due to the limited conditions of use, fishing net lines are frequently in contact with water in various environments, requiring high corrosion resistance. Furthermore, fishing nets need to be dried, necessitating high aging resistance of the fishing net lines under sunlight.

[0003] In existing technologies, polytetrafluoroethylene (PTFE) can be coated onto fishing net lines to improve their aging resistance. The PTFE coating has good weather resistance, which helps extend the overall aging resistance and service life. For example, utility model patent application number 2022226323358 discloses a highly weather-resistant fishing net line with aging resistance, which improves weather resistance through a PTFE coating. However, fishing net lines are frequently bent and rubbed, and the poor abrasion resistance of the PTFE coating easily leads to wear and loss of protection for the core line, requiring improvement. Utility Model Content

[0004] The purpose of this invention is to provide a fishing net line with anti-aging properties, which improves weather resistance and wear protection, and extends service life.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A fishing net line with aging resistance includes: a core wire bundle, an isolation layer, an armor layer, and a sheath layer. The isolation layer is sleeved on the outer side of the core wire bundle. The sheath layer is concentrically disposed on the outer side of the isolation layer. The armor layer is disposed on the outer side of the isolation layer and located in the inner wall of the sheath layer. The wall thickness of the armor layer is less than the wall thickness of the sheath layer.

[0007] The core wire harness includes multiple polyester filaments.

[0008] Multiple polyester filaments are twisted together to form a core bundle.

[0009] The isolation layer is made of heat shrink tubing.

[0010] The sheath layer is made of asphalt.

[0011] The outer side of the sheath layer is provided with a waterproof membrane layer.

[0012] The outer wall of the waterproof membrane layer is provided with a reflective layer.

[0013] The reflective layer is a reflective coating or an aluminum plating layer.

[0014] The armor layer is made of polytetrafluoroethylene fiber.

[0015] The beneficial effects of this utility model are as follows: A fishing net line with anti-aging function has an armor layer impregnated in a sheath layer. The sheath layer protects the armor layer and the isolation layer, preventing the armor layer from participating in external friction, thus improving durability. The armor layer and the sheath layer have good weather resistance. Even if the sheath layer is partially worn, the exposed part of the armor layer can still protect the core wire bundle and the isolation layer, extending the service life and improving anti-aging performance. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model;

[0017] Figure 2 This is a schematic diagram of another embodiment of the present invention. Detailed Implementation

[0018] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0019] like Figure 1 The fishing net line shown has aging resistance and includes: core wire bundle 1, isolation layer 2, armor layer 3 and sheath layer 4. The core wire bundle 1 includes multiple polyester filaments 11, which are twisted together to form the core wire bundle 1, and has good tensile strength.

[0020] The insulating layer 2 is fitted onto the outer surface of the core wire harness 1. In this embodiment, the insulating layer 2 is made of heat-shrink tubing. The heat-shrink tubing is heated and tightened to cover the outer surface of the core wire harness 1, improving the compactness of the core wire harness 1 and preventing loosening after twisting. In addition, the surface of the insulating layer 2 is relatively regular, which is beneficial for the construction of the armor layer 3.

[0021] The sheath layer 4 is concentrically disposed on the outside of the isolation layer 2. In this embodiment, the sheath layer 4 is made of asphalt and formed using rubber asphalt. Rubber asphalt has high high-temperature stability, good low-temperature flexibility, is environmentally friendly, and has good anti-aging properties.

[0022] like Figure 1 As shown, the armor layer 3 is disposed on the outer side of the isolation layer 2 and located in the inner wall of the sheath layer 4. In this embodiment, the wall thickness of the armor layer 3 is less than the wall thickness of the sheath layer 4. The sheath layer 4 protects the armor layer 3 and prevents wear of the armor layer 3.

[0023] In this embodiment, the armor layer 3 is made of polytetrafluoroethylene fiber. Polytetrafluoroethylene fiber has good weather resistance. Even if the sheath layer 4 is partially worn, the exposed part of the armor layer can still protect the core wire harness 1 and the isolation layer 2, thus extending the service life.

[0024] like Figure 2 As shown, in this embodiment, a waterproof membrane layer 5 is provided on the outside of the sheath layer 4. The waterproof membrane layer 5 reduces water resistance and friction, further strengthens the protection of the sheath layer 4, and extends the service life of the sheath layer 4.

[0025] A reflective layer 6 is provided on the outer wall of the waterproof membrane layer 5. In this embodiment, the reflective layer 6 is a reflective coating or an aluminum-plated layer, which can reflect sunlight, reduce the adverse effects of ultraviolet rays on the waterproof membrane layer 5 and the sheath layer 4, and further improve the aging resistance.

[0026] Furthermore, the sheath layer 4 can only be exposed after the reflective layer 6 and the waterproof membrane layer 5 are partially worn, and the armor layer 3 can only be exposed after the sheath layer 4 is partially worn. This achieves multi-layer protection for the core wire harness 1, which helps to extend the overall service life.

[0027] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
