Description

Technical Field

[0001] This application relates to the field of cables, and more specifically, it relates to a method for preparing a stain-resistant cable. Background Technology

[0002] Wire is a broad term, generally referring to long strips of material used for various braiding, manufacturing, or construction purposes. These materials can be metals, plastics, fibers, or other synthetic materials. Wires have a wide range of applications in many fields and industries, and their functions vary. When wires are used in the field of electronic products, they can be data cables, ropes, etc.

[0003] Data cables, as essential electronic connectivity devices, are widely used for data transfer and charging between various electronic products such as mobile phones, tablets, cameras, and hard drives. With technological advancements and diversified consumer demands, data cables not only need efficient data transfer capabilities and good electrical performance, but also require a long lifespan and ease of maintenance. Braided cords, on the other hand, are typically used to manufacture decorative accessories for electronic products, such as mobile phone lanyards.

[0004] However, existing data cables and lanyards often face contamination issues during actual use, especially in dusty, humid, or oily environments. Various contaminants easily accumulate on the surface of data cables and lanyards, making them difficult to clean and affecting the user experience.

[0005] To address this challenge, the industry has widely adopted various measures to improve the anti-fouling properties of cables such as data cables and lanyards. A common method is to coat the cable surface with a protective coating, such as silicone oil or fluorocarbon coatings. These coatings can reduce the adhesion of contaminants to some extent and improve the cable's anti-fouling properties to a certain degree. However, over time, these coatings gradually wear down or fail, losing their original anti-fouling effect. Therefore, developing an economical and efficient method for manufacturing anti-fouling cables has become a key technical problem that urgently needs to be solved. Summary of the Invention

[0006] To achieve better stain resistance and durability, this application provides a method for preparing a stain-resistant wire. The method for preparing the stain-resistant wire involves the following steps:

[0007] 1) Extrude the core insulation material and wrap it around the core, then cure and shape it to form a core insulation layer on the core surface;

[0008] 2) Extrude the outer insulating material to cover the core insulation layer, cure and shape it, forming an outer insulating layer on the core insulation layer, thus creating an insulated wire;

[0009] 3) Braid the rope onto the surface of the insulated wire to form a braided layer on the outer surface of the insulation, thus obtaining the braided wire;

[0010] 4) Apply an anti-fouling agent to the surface of the braided wire, ensuring that the anti-fouling agent is in full contact with the braided layer, and dry it to form an anti-fouling layer on the surface of the braided layer, thus obtaining an anti-fouling wire.

[0011] The antifouling agent is an acrylate dispersion containing antifouling particles, wherein the antifouling particles are one or more of palm wax powder, organosilicon microspheres, and silicone powder.

[0012] By employing the above technical solutions, a multi-layered wire structure is formed, ensuring its anti-fouling performance. First, an insulation layer and an outer insulation layer are formed on the surface of the wire core through extrusion, guaranteeing the electrical safety and mechanical strength of the internal conductive wires. Next, the addition of braided rope further enhances the physical strength and abrasion resistance of the wire. Finally, an acrylic dispersion containing anti-fouling particles is coated and cured on the surface of the braided layer to form an anti-fouling layer. This not only improves the smoothness and hydrophobicity of the wire surface, reducing stain adhesion, but also prevents contaminants from penetrating into the braided layer, extending the wire's service life. The use of anti-fouling particles such as palm wax powder, silicone microspheres, and silicone powder gives the anti-fouling layer higher anti-fouling properties and self-cleaning ability. Simultaneously, the acrylic dispersion promotes the adhesion stability of the anti-fouling particles, preventing them from detaching and wearing away. Furthermore, palm wax powder, silicone microspheres, and silicone powder all possess abrasion resistance, reducing the gradual wear or failure of the anti-fouling layer over time and improving its anti-fouling durability.

[0013] In summary, the production process of this application sequentially forms a core insulation layer, an outer insulation layer, a braided layer, and an anti-fouling layer with stable connections, resulting in a stable structure for the anti-fouling wire. Furthermore, the use of anti-fouling particles such as palm wax powder, organosilicon microspheres, and silicone powder, along with the synergistic effect of acrylate dispersion, ensures that the formed anti-fouling layer possesses both excellent anti-fouling and abrasion resistance, reducing the possibility of contamination in the wire after long-term use.

[0014] Preferably, the acrylate dispersion containing antifouling particles comprises the following parts by weight percentage:

[0015] Hydroxyacrylate 10-20%

[0016] Acetyl acrylate 5-8%

[0017] Vinylcaprolactam 3-8%

[0018] EVA emulsion 10-20%

[0019] Emulsifying dispersant 2-5%

[0020] Initiator 1-3%

[0021] Antifouling granules 1-10%

[0022] The remainder is solvent.

[0023] By employing the above technical solution, the acrylate dispersion containing anti-fouling particles, during its preparation, forms a copolymer with excellent adhesion after copolymerization of hydroxyacrylate, acetylated acrylate, and vinyl caprolactam, enabling stable adhesion to the surface of the braided layer. Simultaneously, this copolymer contains acetyl and amide groups, exhibiting anti-fouling properties and a certain degree of hydrophobicity after curing, which helps reduce the contact area between stain molecules and the material surface, further reducing stain adhesion. Furthermore, the EVA emulsion possesses good adhesion and film-forming stability; the dispersion formed after blending with other components not only forms a stable coating but also, after complete curing, exhibits excellent anti-fouling effect and flexibility, and provides strong isolation against contaminants. After long-term use, the anti-fouling layer is less prone to wear and peeling, reducing the likelihood of staining.

[0024] In summary, the compounding of hydroxy acrylate, acetylated acrylate, vinyl caprolactam, and EVA emulsion achieves a synergistic effect, enhancing adhesion stability, film-forming properties, and weather resistance. Combined with the emulsifying and dispersing effects of emulsifiers and dispersants, the antifouling particles can be evenly dispersed in the original system, resulting in uniform and stable dispersion of antifouling particles in the formed antifouling layer. This reduces the gradual wear or failure of the antifouling layer over time and improves the antifouling durability of the antifouling layer.

[0025] Preferably, the antifouling particles are composed of palm wax powder, organosilicon microspheres, and silicone powder in a weight ratio of 1:(0.1-1):(0.5-1.2).

[0026] By adopting the above technical solution, the antifouling particles are compounded from palm wax powder, organosilicon microspheres, and silicone powder in a specific weight ratio to form a synergistic effect. In the acrylate dispersion containing the antifouling particles, these components jointly improve the stability and uniformity of the dispersion, reduce particle aggregation and deposition, and construct a polymer network structure with antifouling properties. In addition, palm wax powder, organosilicon microspheres, and silicone powder can all form a smooth film on the surface of the antifouling layer. This film has good hydrophobicity, which can effectively resist the adhesion of stains, further improve the antifouling properties of the antifouling layer, and at the same time prevent pollutants from penetrating into the woven layer, reducing the possibility of contamination of the woven layer. It can also prevent the antifouling layer from gradually wearing down or failing, thus improving the antifouling durability of the antifouling layer.

[0027] Preferably, the hydroxyacrylate is polyethylene glycol monomethacrylate and / or hydroxypropyl acrylate.

[0028] By employing the above technical solution, polyethylene glycol monomethacrylate and / or hydroxypropyl acrylate, as hydroxyacrylate components, improve the stability and uniformity of the antifouling agent, reduce particle aggregation and deposition, and enhance the antifouling performance of the antifouling layer. These compounds can also be copolymerized with other acrylate monomers to form polymer materials with more complex structures and properties, further improving the antifouling effect and surface smoothness. By combining with other raw materials, they also provide anti-wear and anti-slip properties, further enhancing the antifouling effect and durability of the antifouling layer.

[0029] Preferably, the acetylacetyl acrylate is one or more of acetylacetoxyethyl acrylate, acetylacetoxypropyl acrylate, and acetylacetoxybutyl acrylate.

[0030] By adopting the above technical solution, the acetylacetic acrylate is one or more of acetylacetoxyethyl acrylate, acetylacetoxypropyl acrylate, and acetylacetoxybutyl acrylate. These specific acetylacetic acrylates can improve the stability and uniformity of the dispersion, reduce particle aggregation and deposition, thereby enhancing the anti-fouling performance of the anti-fouling layer. Simultaneously, these compounds form copolymers with better adhesion during the curing process, further enhancing the stability and durability of the anti-fouling layer, ensuring that the wire surface is not easily stained, thus enhancing wear resistance and preventing peeling, further improving the anti-fouling effect and durability of the anti-fouling layer.

[0031] Preferably, the emulsifying dispersant is composed of the following raw materials in weight percentages:

[0032] Methacrylethyl sulfonyl betaine 38-55%

[0033] Epoxyacetylated linoleic acid methyl ester 20-50%

[0034] Titanium acetylacetonate 12-25%.

[0035] By employing the above technical solution, the methacryloxyethyl sulfobetaine and methyl epoxyacetyl linoleate in the emulsifying dispersant can work synergistically to make the surface of the object smoother and more delicate. A smooth surface helps reduce the adhesion points of stains and improves the anti-fouling effect. Titanium acetylacetonate possesses dispersibility, penetrability, and adhesive stability.

[0036] The combination of titanium acetylacetonate with methacrylethyl sulfobetaine and methyl epoxyacetyl linoleate further enhances the dispersibility of antifouling particles, ensuring uniform dispersion in the raw material system. It also enhances the permeability and adhesion of the acrylate dispersion containing antifouling particles, allowing the acrylate dispersion containing antifouling particles to easily penetrate into the woven layer. After curing, it forms a stable and highly stain-resistant antifouling layer, reducing the gradual wear, peeling, or failure of the antifouling layer over time and improving the stain resistance durability of the antifouling layer.

[0037] Preferably, both the core insulation layer and the outer insulation layer are made of silicone rubber.

[0038] By adopting the above technical solution, silicone rubber material is used for the core insulation layer and the outer insulation layer, which has the following effects: excellent temperature resistance: silicone rubber can maintain good physical and mechanical properties over a wide temperature range, ensuring that the wire can still work normally in high or low temperature environments.

[0039] Excellent electrical insulation properties: Silicone rubber has high electrical insulation strength, which can effectively prevent current leakage and ensure the security of data transmission.

[0040] Strong weather resistance and aging resistance: Silicone rubber has strong resistance to external environmental factors such as ultraviolet rays and ozone, which extends the service life of the wire.

[0041] Excellent softness and elasticity: The silicone rubber material is soft and elastic, making the wire more flexible, easy to bend and not easy to break, thus improving the user experience.

[0042] Preferably, the curing and shaping conditions in steps 1)-2) are: temperature 150-180℃, time 5-10 minutes.

[0043] By adopting the above technical solution, the curing and shaping conditions are set at a temperature of 150-180℃ and a time of 5-10 minutes, ensuring that the insulation layer of the wire core and the outer insulation layer of the adhesive are completely cured, forming a stable structure. Under these conditions, the silicone rubber material can fully exert its temperature resistance, electrical insulation, weather resistance, and aging resistance properties, ensuring the reliability and long service life of the wire in various environments.

[0044] Preferably, the drying temperature in step 4 is 80-98℃ and the drying time is 30-120 minutes.

[0045] By adopting the above technical solution, the antifouling agent can be completely cured to form a stable antifouling layer, thereby preventing cracking of the antifouling layer after long-term use and improving its antifouling durability.

[0046] Preferably, the braided rope is one of nylon, polyester, or acrylic.

[0047] By adopting the above technical solutions, the braided ropes made of nylon, polyester, and acrylic fibers collectively enhance durability, tensile strength, aesthetics, insulation, flexibility, and corrosion resistance in the wire. The selection of these braided ropes ensures that the braided layer maintains good physical and chemical properties during long-term use, thereby extending the wire's lifespan.

[0048] In summary, this application includes at least one of the following beneficial technical effects:

[0049] 1. The production process of this application sequentially forms a core insulation layer, an outer insulation layer, a braided layer, and an anti-fouling layer with stable connections, resulting in a stable structure for the anti-fouling wire. Furthermore, the use of anti-fouling particles such as palm wax powder, organosilicon microspheres, and silicone powder, along with the synergistic effect of acrylate dispersion, gives the formed anti-fouling layer both excellent anti-fouling and abrasion resistance, reducing the possibility of contamination after long-term use.

[0050] 2. The compounding of hydroxy acrylate, acetylated acrylate, vinyl caprolactam and EVA emulsion achieves a synergistic effect, enhancing adhesion stability, film-forming properties and weather resistance. Combined with the emulsifying and dispersing effects of emulsifiers and dispersants, the antifouling particles can be evenly dispersed in the original system, resulting in uniform and stable dispersion of antifouling particles in the formed antifouling layer. This reduces the gradual wear or failure of the antifouling layer over time and improves the antifouling durability of the antifouling layer.

[0051] 3. Antifouling particles such as palm wax powder, organosilicon microspheres, and silicone powder are evenly distributed in the antifouling agent to form a smooth protective film, which not only enhances the antifouling performance but also improves the surface hydrophobicity and abrasion resistance, further enhancing the antifouling effect and service life of the wire.

[0052] 4. The compounding of titanium acetylacetonate with methacrylethyl sulfobetaine and methyl epoxyacetyl linoleate can further enhance the dispersibility of antifouling particles, making them uniformly dispersed in the raw material system. It also enhances the permeability and adhesion of the acrylate dispersion containing antifouling particles, making it easier for the acrylate dispersion containing antifouling particles to penetrate into the woven layer. After curing, it forms an antifouling layer with stable adhesion and good antifouling properties, reducing the gradual wear, peeling or failure of the antifouling layer over time, and improving the antifouling durability of the antifouling layer.

Moreover, after being rubbed with double 85 and silica, the anti-fouling layer is not easy to fall off, wear or fail, etc., and thus the obtained wire has durable anti-fouling properties.

[0149] Combining Examples 8 and 4 with Table 3, it can be seen that the color difference grade of sample 3 in Example 4 is higher than that in Example 8. This indicates that the use of palm wax powder, organosilicon microspheres, and silicone powder has a synergistic effect, further improving wear resistance and stain resistance. This makes the anti-fouling layer on the surface of the obtained wire less prone to contamination by pollutants. After being rubbed with double 85 and silica, the anti-fouling layer is not easy to fall off, wear, or fail, thus the obtained wire has durable anti-fouling properties.

[0150] Combining Examples 9, 11, 14-15, and Table 3, it can be seen that the color difference grades of Sample 3 in Examples 9 and 14-15 are higher than those in Example 11. This indicates that the use of methacryloyl ethyl sulfobetaine, methyl epoxyacetyl linoleate, and titanium acetylacetonate has a synergistic effect, further improving wear resistance, stain resistance, permeability, and adhesion. This makes the anti-fouling layer on the surface of the obtained wire less prone to contamination by pollutants. After being rubbed with double 85 and silica, the anti-fouling layer is not easily peeled off, worn, or failed, thus the obtained wire has durable anti-fouling properties.

[0151] Combining Examples 4 and 16-18 with Table 3, it can be seen that the color difference grades of Sample 2 and Sample 3 in Examples 16-18 are higher than those in Example 1. This indicates that the acrylate dispersion containing antifouling particles prepared using hydroxy acrylate, acetyl acrylate, vinyl caprolactam, EVA emulsion, etc., as described in this application, has water resistance, antifouling properties, and adhesion stability. The cured antifouling layer has better antifouling performance and durability.
