Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel composite wires, in particular to a stainless steel composite wire. Background Art

[0002] Stainless steel composite wires are mostly made of ordinary low-carbon steel wires, which are formed by cutting, bending, weaving, and welding, and then assembled into products through processes such as pickling, nickel or chromium electroplating, and polishing, so that they have a bright, beautiful appearance and corrosion resistance. Such products are widely used in people's daily lives and have a wide range of uses.

[0003] The pickling, electroplating and other processes in the production process of conventional stainless steel composite wires not only increase the production cost, but also make the stainless steel wires themselves susceptible to structural damage to the surface coating due to external forces in the external environment to a certain extent, thereby losing their original protective effect and reducing the service life of the wires.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a stainless steel composite wire is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a stainless steel composite wire to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a stainless steel composite wire, comprising a stainless steel inner core and a first memory protective layer, the outer surface annular array of the stainless steel inner core has the first memory protective layer, and the outside of the first memory protective layer is coated with a compressive protective layer, and the outer annular array of the compressive protective layer has a second memory protective layer, and the outside of the second memory protective layer is provided with an outer protective layer.

[0007] Furthermore, a first anti-rust layer is filled between the stainless steel inner core and the pressure-resistant protective layer, and the first memory protective layer is located inside the first anti-rust layer and is completely covered by the first anti-rust layer.

[0008] Furthermore, a second anti-rust layer is filled between the compression protection layer and the outer protection layer, and the second memory protection layer is located inside the second anti-rust layer and is completely covered by the second anti-rust layer.

[0009] Furthermore, the surfaces of the stainless steel inner core and the pressure-resistant protective layer are sprayed with a polytetrafluoroethylene protective layer, and the surface of the outer protective layer is sprayed with a polyurethane coating.

[0010] Furthermore, the outer protective layer and the second memory protective layer are connected by an embedded structure, and the cross-section of the first memory protective layer is a circular structure.

[0011] Furthermore, the first anti-rust layer is fully filled between the stainless steel inner core and the pressure-resistant protective layer, and the second anti-rust layer is fully filled between the pressure-resistant protective layer and the outer protective layer.

[0012] Furthermore, the first anti-rust layer and the second anti-rust layer are made of the same material, and the first anti-rust layer and the second anti-rust layer provide anti-rust protection for the surfaces of the stainless steel inner core and the pressure-resistant protective layer respectively.

[0013] Furthermore, the stainless steel inner core and the pressure-resistant protective layer are made of the same material, and the first memory protective layer is tightly fitted between the stainless steel inner core and the pressure-resistant protective layer.

[0014] The utility model provides a stainless steel composite wire material, which has the following beneficial effects:

[0015] 1. The utility model provides a first memory protective layer and a second memory protective layer on the outside of the stainless steel inner core, wherein the first memory protective layer and the second memory protective layer are both made of high-density memory rubber material. The rubber with memory function is a new type of polymer elastic material, which can be repeatedly bent and deformed during use, but its shape can still be restored to its initial state, and has good repair ability, and has high toughness and elasticity. During use, the durability of the article itself can be effectively enhanced and the service life can be extended. In addition, it has good anti-slip and shock-proof functions. Therefore, it can not affect the bending of the stainless steel inner core itself to the greatest extent, but can also help it reduce a certain degree of damage, and at the same time reduce the friction damage caused by external forces, thereby ensuring the service life.

[0016] 2. The utility model sprays a polytetrafluoroethylene protective layer and a polyurethane coating on the surface of the stainless steel inner core and the surface of the outer protective layer respectively. Due to the material characteristics of the polytetrafluoroethylene protective layer itself, its air-impermeability and water-impermeability isolate the stainless steel inner core from contact with oxygen and water, forming a good anti-rust effect, so that even if the external protective structures are structurally damaged and the entire stainless steel inner core is exposed to the external environment, it can still have good structural self-protection to a certain extent to ensure safety of use, and the main component of the polyurethane coating is polyurethane resin. Since the polyurethane coating has the characteristics of wear resistance, corrosion resistance, and UV resistance, it can effectively protect the outer protective layer from the influence of the external environment. In addition, the polyurethane coating also has excellent adhesion, which can enhance the hardness and durability of the outer protective layer, so that the whole has good stability even if it is exposed to the external environment for a long time.

[0017] 3. In the utility model, since the anti-compression protective layer is made of the same material as the stainless steel inner core, a polytetrafluoroethylene protective layer is also sprayed on its surface to ensure the safety of the structure, and by utilizing its super corrosion resistance, it is almost not corroded by any chemical reagents, including strong acids and alkalis, so that even if the outer protective layer and the second memory protective layer have a certain degree of structural damage, the anti-compression protective layer is exposed to the external environment and can still maintain a certain structural stability and strength. In addition, by utilizing the minimum surface tension characteristic of the polytetrafluoroethylene protective layer in the solid material, the anti-compression protective layer can not adhere to any stains even if the surface is sprayed with the polytetrafluoroethylene protective layer, thereby avoiding erosion damage. In addition, the use of the first anti-rust layer and the second anti-rust layer can help to double isolate the stainless steel inner core and the anti-compression protective layer, as well as the anti-compression protective layer and the outer protective layer from external water and air erosion, thereby avoiding damage to the stainless steel inner core and the outer protective layer, which leads to structural damage.

[0025] like Figures 1 to 4 As shown, the second antirust layer 7 is filled between the pressure-resistant protective layer 3 and the outer protective layer 5, and the second memory protective layer 4 is inside the second antirust layer 7 and is completely covered by the second antirust layer 7, the first antirust layer 6 is fully filled between the stainless steel inner core 1 and the pressure-resistant protective layer 3, and the second antirust layer 7 is fully filled between the pressure-resistant protective layer 3 and the outer protective layer 5, the first antirust layer 6 and the second antirust layer 7 are made of the same material, and the first antirust layer 6 and the second antirust layer 7 provide antirust protection for the surfaces of the stainless steel inner core 1 and the pressure-resistant protective layer 3 respectively. Layer 3 is made of the same material as the stainless steel core 1. To ensure the safety of the structure, a polytetrafluoroethylene protective layer 8 is also sprayed on its surface. Even if the outer protective layer 5 and the second memory protective layer 4 are structurally damaged to a certain extent, so that the pressure-resistant protective layer 3 is exposed to the external environment, a certain structural stability and strength can still be maintained. In addition, the use of the first anti-rust layer 6 and the second anti-rust layer 7 can help to double isolate the stainless steel core 1 and the pressure-resistant protective layer 3, as well as the pressure-resistant protective layer 3 and the outer protective layer 5 from external water and air erosion.

[0026] like Figures 1 to 4As shown, the surfaces of the stainless steel inner core 1 and the pressure-resistant protective layer 3 are sprayed with a polytetrafluoroethylene protective layer 8, the surface of the outer protective layer 5 is sprayed with a polyurethane coating 9, the outer protective layer 5 is connected to the second memory protective layer 4 with an embedded structure, and the cross-section of the first memory protective layer 2 is a circular structure, the stainless steel inner core 1 and the pressure-resistant protective layer 3 are made of the same material, and the first memory protective layer 2 is tightly fitted between the stainless steel inner core 1 and the pressure-resistant protective layer 3, and the polytetrafluoroethylene protective layer 8 and the polyurethane coating 9 are sprayed on the surface of the stainless steel inner core 1 and the surface of the outer protective layer 5 respectively, so that even if the external protective structures are structurally damaged so that the entire stainless steel inner core 1 is exposed to the external environment, it can still have good structural self-protection to a certain extent, and at the same time can effectively protect the outer protective layer 5 from the influence of the external environment, and enhance the hardness and durability of the outer protective layer 5.

[0027] In summary, if Figures 1 to 4 As shown, when the stainless steel composite wire is used, firstly, during the use of the entire wire, under the action of the outer protective layer 5, the polyurethane coating 9 sprayed on the surface can provide a certain degree of structural protection from the outermost part of the overall structure, thereby minimizing the exposure of the internal structure caused by external friction;

[0028] The first memory protection layer 2 and the second memory protection layer 4 made of memory rubber material can provide a certain degree of anti-cutting protection for the innermost stainless steel core 1 by utilizing the characteristics of its structure. At the same time, it can also flexibly deform the structure in accordance with the bending of the stainless steel core 1 to avoid affecting the adjustability of the overall structure of the wire.

[0029] During the entire process of using the wire, the use of the first anti-rust layer 6 and the second anti-rust layer 7 can help to double isolate the stainless steel inner core 1 and the pressure-resistant protective layer 3, and between the pressure-resistant protective layer 3 and the outer protective layer 5 from external water and air erosion, and can also help protect the contact surfaces between the structural layers, thereby improving the strength and flexibility of the entire wire. The polytetrafluoroethylene protective layer 8 on the surface of the stainless steel inner core 1 ensures that even if the external protective structures are structurally damaged and the entire stainless steel inner core 1 is exposed to the external environment, it can still have good structural self-protection to a certain extent.
