Description

Technical Field

[0001] The present application relates to the field of cables, and more specifically, to a method for preparing anti-fouling wire materials. Background Art

[0002] Wire material is a general term, usually referring to long strip materials used for various knitting, manufacturing or construction purposes. These materials can be metals, plastics, fibers or other synthetic materials. Wire materials have a wide range of applications in multiple fields and industries, and their functions are also different. When wire materials are applied in the field of electronic products, the wire materials can be data cables, ropes, etc.

[0003] As an important electronic connection device, a data cable is widely used for data transmission and charging between various electronic products such as mobile phones, tablets, cameras, hard drives, etc. With the progress of technology and the diversification of consumer demands, a data cable not only needs to have efficient data transmission capabilities and good electrical performance, but also needs to have a long service life and be easy to maintain. And a braided rope is usually used to produce decorative accessories in electronic products, such as mobile phone lanyards, etc.

[0004] However, existing data cables and lanyards often face pollution problems during actual use. Especially in a dusty, humid or greasy environment, various pollutants are likely to accumulate on the surfaces of data cables and lanyards, resulting in difficulty in cleaning and affecting the user experience.

[0005] To address this challenge, the industry generally adopts a variety of measures to improve the anti-fouling performance of wire materials such as data cables and lanyards. Common methods include coating a protective coating on the surface of the wire material, such as silicone oil, fluorocarbon coatings, etc. These coatings can reduce the attachment of pollutants to a certain extent; to a certain extent, the anti-fouling performance of the wire material is improved, but over time, these coatings will gradually wear or fail and lose their original anti-fouling effect. Therefore, how to develop an economical and efficient method for preparing anti-fouling wire materials has become a key technical problem to be solved urgently. Summary of the Invention

[0006] In order to obtain better anti-fouling property and anti-fouling persistence, the present application provides a method for preparing an anti-fouling wire material, which is obtained by the following method: 1) Extrude the core insulating rubber compound, wrap the core, and cure and shape it to form a core insulating layer on the surface of the core; 2) Extrude the outer insulating rubber compound to wrap the core insulating layer, cure and shape it to form an outer insulating layer on the core insulating layer, an insulated wire; 3) Weave a braided rope on the surface of the insulated wire to form a braided layer on the surface of the outer insulating layer to obtain a braided wire; 4) Coat an anti-fouling agent on the surface of the sheathed wire, make the anti-fouling agent fully contact with the braided layer, dry it, and form an anti-fouling layer on the surface of the braided layer to obtain an anti-fouling wire; The anti-fouling agent is an acrylate dispersion containing anti-fouling particles, and the anti-fouling particles are one or more of palm wax powder, silicone microspheres, and silicone powder.

[0007] By adopting the above technical solution, a wire with a multi-layer structure is formed, ensuring the anti-fouling performance of the wire. First, the core insulation layer and the outer insulation layer are formed on the surface of the core by extrusion, ensuring the electrical safety and mechanical strength of the internal conductive wire. Then, the addition of the braided rope further enhances the physical strength and wear resistance of the wire. Finally, coating the acrylate dispersion containing anti-fouling particles and curing on the surface of the braided layer to form an anti-fouling layer not only improves the smoothness and hydrophobicity of the wire surface, reduces the adhesion of stains, but also prevents pollutants from penetrating into the interior of the braided layer, extending the service life of the wire. The use of anti-fouling particles such as palm wax powder, silicone microspheres, and silicone powder makes the anti-fouling layer have higher anti-fouling and self-cleaning capabilities. At the same time, the acrylate dispersion used can promote the adhesion stability of the anti-fouling particles, avoid their shedding and abrasion, and at the same time, palm wax powder, silicone microspheres, and silicone powder all have wear resistance, reducing the gradual wear or failure of the anti-fouling layer over time and improving the anti-fouling durability of the anti-fouling layer.

[0008] In summary, through the production process of this application, the core insulation layer, the outer insulation layer, the braided layer, and the anti-fouling layer are formed in sequence and are stably connected, making the structure of the anti-fouling wire stable. And through the use of anti-fouling particles such as palm wax powder, silicone microspheres, and silicone powder, and with the cooperation of the acrylate dispersion, the formed anti-fouling layer has both good anti-fouling and wear resistance, reducing the possibility of pollution of the wire after long-term use.

[0009] Preferably, the acrylate dispersion containing anti-fouling particles is composed of the following weight percentage components: Hydroxy acrylate 10 - 20% Acetyl acrylate 5 - 8% Vinyl caprolactam 3 - 8% EVA emulsion 10 - 20% Emulsifying dispersant 2 - 5% Initiator 1 - 3% Anti-fouling particles 1 - 10% The balance is solvent.

[0010] By adopting the above technical scheme, during the preparation process of the acrylic ester dispersion containing anti-fouling particles, hydroxy acrylate, acetyl acrylate, and vinyl caprolactam are copolymerized to form a copolymer with better adhesion, which can stably adhere to the surface of the braided layer. At the same time, the copolymer contains acetyl and amide groups, which have anti-fouling properties and a certain hydrophobicity after curing, which helps to reduce the contact area between the stain molecules and the surface of the material, and further reduce the adhesion ability of the stains. In addition, EVA emulsion has good adhesion and film-forming stability. The dispersion formed after blending with other ingredients can not only form a coating with stable adhesion, but also the anti-fouling layer after complete curing has better anti-fouling effect and flexibility, and has a strong isolation effect on pollutants. After the wire has been used for a long time, the anti-fouling layer is not prone to wear and fall off, reducing the possibility of stains.

[0011] In summary, the compounding of hydroxy acrylate, acetyl acrylate, vinyl caprolactam and EVA emulsion can achieve a synergistic effect, enhance adhesion stability, film-forming properties and weather resistance, and cooperate with the emulsifying and dispersing effect of the emulsifier dispersant, so that the anti-fouling particles can be evenly dispersed in the original system, and the anti-fouling particles in the formed anti-fouling layer are evenly dispersed and stably dispersed, thereby reducing the gradual wear or failure of the anti-fouling layer of the wire over time and improving the anti-fouling durability of the anti-fouling layer.

[0012] Preferably, the antifouling particles are composed of palm wax powder, silicone microspheres and silicone powder in a weight ratio of 1:(0.1-1):(0.5-1.2).

[0013] By adopting the above technical solution, the anti-fouling particles are compounded by palm wax powder, silicone microspheres, and silicone powder in a specific weight ratio to form a synergistic effect. In the acrylic ester dispersion containing anti-fouling particles, these ingredients jointly improve the stability and uniformity of the dispersion, reduce the aggregation and deposition of particles, and construct a polymer network structure with anti-fouling properties. In addition, palm wax powder, silicone microspheres, and silicone powder can form a smooth film on the surface of the anti-fouling layer. This film has good hydrophobicity and can effectively resist the adhesion of stains, further improving the anti-fouling property of the anti-fouling layer, while preventing pollutants from penetrating into the woven layer, reducing the possibility of contamination of the woven layer, and preventing the anti-fouling layer from gradually wearing out or failing, thereby improving the anti-fouling durability of the anti-fouling layer.

[0014] Preferably, the hydroxyacrylate is polyethylene glycol monomethacrylate and / or hydroxypropyl acrylate.

[0015] By adopting the above technical solution, polyethylene glycol monomethacrylate and / or hydroxypropyl acrylate as the hydroxyacrylate component improve the stability and uniformity of the anti-fouling agent, reduce the aggregation and deposition of particles, and enhance the anti-fouling performance of the anti-fouling layer. These compounds can also copolymerize with other acrylate monomers to form polymer materials with more complex structures and properties, further improving the anti-fouling effect and surface finish. By cooperating with other raw materials, they play a role in anti-wear and anti-abrasion, further enhancing the anti-fouling effect and anti-fouling persistence of the anti-fouling layer.

[0016] Preferably, the acetyl acrylate is one or more of ethyl acetoacetoxy acrylate, propyl acetoacetoxy acrylate, and butyl acetoacetoxy acrylate.

[0017] By adopting the above technical solution, the acetyl acrylate being one or more of ethyl acetoacetoxy acrylate, propyl acetoacetoxy acrylate, and butyl acetoacetoxy acrylate can improve the stability and uniformity of the dispersion liquid, reduce the aggregation and deposition of particles, thereby enhancing the anti-fouling performance of the anti-fouling layer. At the same time, these compounds form copolymers with better adhesion during the curing process, further enhancing the stability and persistence of the anti-fouling layer, ensuring that the surface of the wire is not easily stained, that is, enhancing the anti-wear and anti-abrasion effects, and further enhancing the anti-fouling effect and anti-fouling persistence of the anti-fouling layer.

[0018] Preferably, the emulsifying dispersant is composed of the following raw materials by weight percentage: Methacryloylethyl sulfobetaine 38 - 55% Epoxy acetyl linoleic acid methyl ester 20 - 50% Titanium acetylacetonate 12 - 25%.

[0019] By adopting the above technical solution, methacryloylethyl sulfobetaine and epoxy acetyl linoleic acid methyl ester in the emulsifying dispersant can act synergistically to make the surface of the object smoother and more delicate. The smooth surface helps to reduce the attachment points of stains and improve the anti-fouling effect. Titanium acetylacetonate has dispersibility, permeability, and adhesion stability.

[0020] When titanium acetylacetonate is compounded with methacryloylethyl sulfobetaine and epoxy acetyl linoleic acid methyl ester, it can further enhance the dispersibility of the anti-fouling particles, making them evenly dispersed in the raw material system, and also enhancing the permeability and adhesion of the acrylate dispersion liquid containing anti-fouling particles, making the acrylate dispersion liquid containing anti-fouling particles easily penetrate into the braided layer. After curing, it forms an anti-fouling layer with stable adhesion and good anti-fouling properties, reducing the gradual wear, shedding, or failure of the anti-fouling layer over time, and improving the anti-fouling persistence of the anti-fouling layer.

[0021] Preferably, both the core insulation layer and the outer insulation layer are made of silicone rubber material.

[0022] By adopting the above technical solution, using silicone rubber material for the core insulation layer and the outer insulation layer has the following effects: excellent temperature resistance: Silicone rubber can maintain good physical and mechanical properties within a wide temperature range, ensuring that the wire can still work properly in high or low temperature environments.

[0023] Excellent electrical insulation performance: Silicone rubber has a high electrical insulation strength, which can effectively prevent current leakage and ensure the security of data transmission.

[0024] Strong weather resistance and aging resistance: Silicone rubber has strong resistance to external environmental factors such as ultraviolet rays and ozone, extending the service life of the wire.

[0025] Good flexibility and elasticity: The silicone rubber material is soft and elastic, making the wire more flexible, easy to bend without breaking, and improving the user experience.

[0026] Preferably, the curing and shaping conditions in the steps 1)-2) are: temperature 150 - 180 °C, time 5 - 10 minutes.

[0027] By adopting the above technical solution, setting the curing and shaping conditions to a temperature of 150 - 180 °C and a time of 5 - 10 minutes can ensure that the rubber materials of the core insulation layer and the outer insulation layer are completely cured, forming a stable structure. Under this condition, the silicone rubber material can fully exert its temperature resistance, electrical insulation, weather resistance and aging resistance, ensuring the reliability and long service life of the wire in various environments.

[0028] Preferably, the drying temperature in step 4 is 80 - 98 °C, and the drying time is 30 - 120 minutes.

[0029] By adopting the above technical solution, the anti-fouling agent can be completely cured to form an anti-fouling layer with stable adhesion, thereby avoiding phenomena such as cracking of the anti-fouling layer after long-term use of the wire and improving the durability of its anti-fouling performance.

[0030] Preferably, the braided rope is one of nylon, polyester, and acrylic.

[0031] By adopting the above technical solution, nylon, polyester, and acrylic as the braided ropes of the braided layer jointly play the advantages of enhancing durability, improving tensile strength, enhancing aesthetics, enhancing insulation, improving flexibility and corrosion resistance in the wire. The selection of these braided ropes can ensure that the braided layer maintains good physical and chemical properties during long-term use, thereby extending the service life of the wire.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the production process of this application, the core insulation layer, insulation outer layer, braided layer, and anti-fouling layer are formed in sequence with stable connections, making the structure of the anti-fouling wire stable. By using anti-fouling particles such as palm wax powder, silicone microspheres, and silicone powder, and with the cooperation of acrylate dispersion liquid, the formed anti-fouling layer has both good anti-fouling property and wear resistance, reducing the possibility of pollution occurring after long-term use of the wire; 2. By compounding hydroxyacrylate, acetyl acrylate, vinyl caprolactam, and EVA emulsion, a synergistic effect is achieved, enhancing adhesion stability, film-forming property, and weather resistance. Then, with the emulsification and dispersion of the emulsifying dispersant, the anti-fouling particles can be evenly dispersed in the original system, making the anti-fouling particles in the formed anti-fouling layer evenly dispersed and stable, reducing the gradual wear or failure of the anti-fouling layer of the wire over time, and improving the anti-fouling persistence of the anti-fouling layer; 3. Anti-fouling particles such as palm wax powder, silicone microspheres, and silicone powder are evenly distributed in the anti-fouling agent, forming a smooth protective film, which not only enhances the anti-fouling performance but also improves the surface hydrophobicity and wear resistance, further enhancing the anti-fouling effect and service life of the wire; 4. The compounding of titanium acetylacetonate with methacryloylethyl sulfobetaine and epoxy acetyl linolenate methyl ester can further enhance the dispersibility of the anti-fouling particles, making them evenly dispersed in the raw material system, and also enhancing the permeability and adhesion of the acrylate dispersion liquid containing anti-fouling particles. It makes the acrylate dispersion liquid containing anti-fouling particles easily penetrate into the braided layer, and after curing, forms an anti-fouling layer with stable adhesion and good anti-fouling property, reducing the gradual wear, shedding, or failure of the anti-fouling layer over time, and improving the anti-fouling persistence of the anti-fouling layer.
