Description

Technical Field

[0001] This invention relates to the field of optical cable manufacturing technology, specifically to a new type of precise, efficient, and durable power optical cable for 5G / B5G infrastructure and its manufacturing process. Background Technology

[0002] Power optical cables include all-dielectric self-supporting optical cables (ADSS optical cables) and optical fiber composite overhead ground wire optical cables (OPGW optical cables), etc. They have optical performance, mechanical performance and environmental adaptability, and provide data transmission for power communication networks. The optical cable is composed of a cable core and an outer layer material. The cable core is optical fiber (such as glass fiber), and the outer layer material includes a plastic protective sheath, a waterproof layer, a buffer layer, and insulated metal conductors.

[0003] By coating the outer layer of the cable core with polyurethane foam and then compounding it with materials such as ethylene glycol, silicon powder, and whisker silicon, the resulting optical cable has high toughness, cold resistance, and mechanical strength. However, the polyurethane foam coating has poor aging resistance and is prone to yellowing and embrittlement when exposed to ultraviolet light for a long time. In addition, the optical fiber cable core contains a large number of residual hydroxide ions that interfere with light energy and cause Rayleigh scattering, which affects the transmission performance of the power optical cable. Furthermore, the power optical cable also has poor low-temperature cycling stability, and the fiber attenuation will increase significantly, affecting the signal transmission quality and distance. Summary of the Invention

[0004] This invention provides a novel, precise, efficient, and durable power optical cable for 5G / B5G infrastructure and its manufacturing process, which solves the problems of poor low-temperature cycling stability, mechanical properties, and aging resistance of power optical cables, thus affecting their transmission performance.

[0005] The technical solution of the present invention:

[0006] A manufacturing process for a novel, precise, efficient, and durable power optical cable for 5G / B5G infrastructure includes the following steps:

[0007] S1. Silicon chloride, germanium, and boron are introduced into a quartz glass tube, followed by oxygen and helium. After high-temperature sintering, an optical fiber preform is obtained. The optical fiber preform is drawn into a wire to obtain a cable core.

[0008] S2. Apply the inner layer composite material to the surface of the cable core, cure it at 80-90℃ for 1-2 hours, remove it, and cool it to room temperature to obtain a cable core covered with a protective inner layer.

[0009] S3. Place the cable core covered with the protective inner layer in the outer foamed composite material, foam and cure at 70-80℃ for 1-2 hours, take it out, dry it, and you will get the cable core covered with the protective outer layer, i.e., the durable power optical cable.

[0010] The inner layer composite material is obtained by reacting porous carbon, tetraethyl orthosilicate and germanium chloride together, and then reacting them with methyltrimethoxysilane.

[0011] The outer foamed composite material comprises the following raw materials in parts by weight: 50-60 parts of waterborne polyurethane, 30-40 parts of ethylene glycol, 4-5 parts of composite silicon powder, 5-6 parts of whisker silicon, 1-3 parts of crosslinking agent, 2-4 parts of foaming agent, 3-5 parts of light stabilizer, 1-2 parts of UV absorber, 0.5-1 part of antioxidant, and 80-100 parts of deionized water;

[0012] The composite silicon powder is obtained by reacting shellac-coated silicon powder with melamine and formaldehyde, and then coating it with a pretreated sheet material.

[0013] Furthermore, in step S1, the high-temperature sintering temperature is 1200-1300℃, the high-temperature sintering time is 2-6h; the wire drawing temperature is 1900-2100℃; and the cable core diameter is 20-50um.

[0014] Furthermore, in step S2, the thickness of the protective inner layer is 0.3-0.5 mm.

[0015] Furthermore, in step S3, the thickness of the protective outer layer is 0.1-0.2 mm.

[0016] Furthermore, the inner composite material is prepared by the following steps:

[0017] A1. Tetraethyl orthosilicate was added to deionized water and ethanol, stirred evenly, hydrochloric acid was added to adjust the pH to 1-2, germanium chloride and porous carbon were added, and stirred at 300-400 r / min for 1-2 h. After standing and aging, the mixture was dried and heat-treated at 900-1200℃ for 4-5 h. After cooling to room temperature, porous carbon loaded with nanomaterials was obtained.

[0018] A2. Add methyltrimethoxysilane to deionized water and ethanol, stir until homogeneous, add hydrochloric acid to adjust the pH to 2-3, add porous carbon loaded with nanomaterials, and stir at 400-500 r / min for 30-40 min to obtain the inner layer composite material.

[0019] Furthermore, during the A1 reaction described above, the hydrolysis products of tetraethyl orthosilicate and germanium chloride can be bonded together through silicon-oxygen-germanium bonds to form a sol structure. Porous carbon has excellent adsorption properties, which allows the sol to penetrate into the pores of the porous carbon. After heat treatment, a network structure of germanium dioxide-silica nanomaterials can be formed in the porous carbon, thus obtaining porous carbon loaded with nanomaterials.

[0020] Furthermore, during the A2 reaction described above, methyltrimethoxysilane undergoes hydrolysis and condensation to form an organic-inorganic hybrid network. The silanol groups generated by hydrolysis can chemically bond with the hydroxyl groups on the porous carbon surface of the supported nanomaterials, thereby uniformly dispersing the porous carbon of the supported nanomaterials in the organic-inorganic hybrid network as an inner composite material.

[0021] Further, in step A1, the ratio of tetraethyl orthosilicate, deionized water, ethanol, germanium chloride and porous carbon is (5.1-5.5)g:(35-45)mL:(90-110)mL:(2.5-2.9)g:(12-15)g.

[0022] Further, in step A2, the ratio of the amount of methyltrimethoxysilane, deionized water, ethanol and porous carbon supporting nanomaterials is (18-22)g:(35-45)mL:(75-85)mL:(10-11)g.

[0023] Furthermore, the composite silicon powder is specifically prepared by the following steps:

[0024] B1. Add shellac to ethanol and stir well. Add silica powder and stir at 400-500 r / min for 5-10 min. Heat to 65-75℃ and continue stirring for 30-40 min. Filter to collect the solid. Wash the solid and dry it to obtain shellac-coated silica powder.

[0025] B2. Mix melamine, formaldehyde and deionized water, stir at 100-200 r / min for 13-15 min, add triethanolamine to adjust the pH to 8-10, add shellac-coated silica powder, stir and react at 65-75℃ for 25-35 min, filter, wash and dry to obtain modified silica powder.

[0026] B3. Add the pretreated sheet material and modified silicon powder to ethanol, stir evenly, let stand, filter, wash and dry to obtain composite silicon powder.

[0027] Furthermore, in the above B1 reaction process, shellac dissolves in the organic solvent ethanol, exhibiting excellent film-forming properties. Moreover, the oxygen-containing functional groups of shellac are chemically bonded to silicon powder, allowing shellac to be grafted onto the surface of silicon powder, resulting in shellac-coated silicon powder.

[0028] Furthermore, during the B2 reaction process described above, triethanolamine provides an alkaline environment, which allows the amine groups of melamine to undergo a condensation reaction with formaldehyde to form a melamine-formaldehyde prepolymer. The oxygen-containing functional groups in the shellac-coated silica powder can undergo a cross-linking reaction with the hydroxymethyl groups in the melamine-formaldehyde prepolymer, thereby forming a cross-linked polymer on the surface of the silica powder to obtain modified silica powder.

[0029] Furthermore, during the B3 reaction process described above, the surface of the pretreated sheet material contains a large number of phenolic hydroxyl groups and has excellent adhesion, enabling it to adhere to the surface of the modified silicon powder to obtain composite silicon powder.

[0030] Further, in step B1, the ratio of shellac, ethanol and silica powder is (2-3)g:(20-30)mL:(5.6-6)g.

[0031] Further, in step B2, the ratio of melamine, formaldehyde, deionized water and shellac-coated silica powder is (4-6)g:(8-12)mL:(18-22)mL:(6.1-6.5)g.

[0032] Further, in step B3, the ratio of the pretreated sheet material, modified silicon powder, and ethanol is (1.5-1.7)g:(5.7-5.9)g:(80-100)mL.

[0033] Furthermore, the silicon powder particle size is 4-5 μm.

[0034] Furthermore, the outer foamed composite material is prepared by the following steps:

[0035] Waterborne polyurethane, ethylene glycol, composite silicon powder, whisker silicon, crosslinking agent, foaming agent, light stabilizer, UV absorber, antioxidant and deionized water are mixed and stirred at 300-500 r / min for 40-50 min to obtain the outer foamed composite material.

[0036] Furthermore, the crosslinking agent is selected from any one of methyltriketoxime silane, methyltriacetoxy silane, or vinyltributylone oxime silane.

[0037] Furthermore, the light stabilizer is selected from light stabilizer 770 or light stabilizer LQ-622.

[0038] Furthermore, the UV absorber is selected from any one of UV-1, UV-196, and UV-NP3.

[0039] Furthermore, the antioxidant is selected from any one of antioxidant 1010, antioxidant 245, antioxidant 30N, sodium thiosulfate, and triphenyl phosphite.

[0040] The present invention has the following beneficial effects:

[0041] (1) In the technical solution of the present invention, a germanium dioxide-silica nanomaterial with a network structure is formed in porous carbon. On the one hand, the formed germanium dioxide-silica nanomaterial is used as a hydrogen absorption material to absorb hydrogen elements generated inside the optical fiber core, thereby avoiding interference of light energy by residual hydroxide ions inside the optical fiber core, Rayleigh scattering, and affecting the transmission performance of the power optical cable. On the other hand, porous carbon has excellent adsorption performance and can also adsorb hydrogen elements generated inside the optical fiber core. As a carrier of germanium dioxide-silica nanomaterial, it adsorbs and fixes the nanomaterial, avoiding the migration and precipitation of small-sized nanomaterials on the surface of the core.

[0042] (2) In the technical solution of the present invention, the porous carbon loaded with nanomaterials is uniformly dispersed in an organic-inorganic hybrid network as an inner composite material; methyltrimethoxysilane is hydrolyzed and polycondensed to form an organic-inorganic hybrid network, which can be uniformly coated on the surface of the cable core to form a protective inner layer with high water resistance, blocking environmental moisture and reducing the penetration of hydrogen impurity water molecules. Moreover, the porous carbon loaded with nanomaterials is uniformly dispersed in an organic-inorganic hybrid network, increasing the crosslinking density and enhancing mechanical strength.

[0043] (3) In the technical solution of the present invention, shellac is grafted onto the surface of silica powder, thereby forming a silica powder coating on the surface of the pretreated cable core. This can reduce the freezing point of the power optical cable, so that the power optical cable will not easily freeze in a low temperature and humid environment, and has excellent antifreeze performance. Moreover, the fatty acid structure contained in shellac can improve the waterproof and moisture-proof performance of silica powder, and prevent silica powder from easily absorbing water and clumping, which affects the antifreeze performance. A cross-linked polymer is formed on the surface of silica powder, which has good toughness and impermeability, further reducing the permeability of water molecules. The cross-linked polymer has high toughness, which enhances the mechanical strength of the power optical cable. A sheet material is deposited on the surface of modified silica powder. On the one hand, the sheet material is deposited on the surface of modified silica powder, which increases the surface roughness of silica powder and increases the contact area between silica powder and polyurethane and ethylene glycol, which is conducive to forming a stable wrapping layer on the surface of the cable core. On the other hand, the sheet material can block the penetration of oxygen and water molecules and inhibit the expansion of cracks, thereby improving the aging resistance and mechanical strength of the power optical cable.

[0044] (4) In the technical solution of the present invention, by doping germanium and boron rare earth elements into the optical fiber cable core, the interference of residual hydroxide ions with light energy can be reduced, Rayleigh scattering occurs, and the transmission performance of the power optical cable is affected; the outer foamed composite material is wrapped on the surface of the cable core as a protective outer layer, containing polyurethane, ethylene glycol, silicon powder and other components. The coating formed by polyurethane has high density and good heat preservation effect, ethylene glycol has long-lasting antifreeze properties, and silicon powder can reduce the freezing point of the power optical cable and is not easy to freeze in low temperature and humid environment. The combination of the three effectively enhances the antifreeze, weather resistance and mechanical strength of the outer shell, ensuring that the optical fiber has high transmission performance at -70℃.

[0200] The test results are shown in Table 1 below.

[0201] Table 1 Performance testing of durable power optical cables prepared in Examples 1-3 and Comparative Examples 1-5

[0202]

[0203]

[0204] As can be seen from the data in Table 1, the durable power optical cables prepared in Examples 1-3 have high mechanical properties, transmission performance, and low-temperature resistance.

[0205] In Comparative Example 1, the durable power optical cable obtained by replacing the porous carbon loaded with nanomaterials with an inner composite material prepared from nanomaterials and coating it on the cable core exhibited decreased mechanical and transmission performance. This demonstrates that germanium dioxide-silicon dioxide nanomaterials, when coated as hydrogen-absorbing materials, can absorb hydrogen elements generated inside the optical fiber cable core, preventing residual hydroxide ions inside the optical fiber cable core from interfering with light energy, causing Rayleigh scattering, and affecting the transmission performance of the power optical cable.

[0206] The durable power optical cable obtained by coating the cable core with the inner layer composite material prepared without the addition of methyltrimethoxysilane in Comparative Example 2 showed a decrease in performance, which proved that the porous carbon loaded with nanomaterials was uniformly dispersed in the organic-inorganic hybrid network. As the inner layer composite material, it formed an organic-inorganic hybrid network on the surface of the cable core, which has high water resistance, blocks environmental moisture, reduces the penetration of hydrogen-containing impurity water molecules, and enhances mechanical strength.

[0207] Comparative Example 3 showed that replacing the shellac-coated silica powder with a composite silica powder coating on the cable core resulted in a durable power optical cable with decreased mechanical and transmission performance. This demonstrates that grafting shellac onto the silica powder surface can lower the freezing point of the power optical cable, preventing it from easily freezing in low-temperature and humid environments and exhibiting excellent antifreeze properties. Furthermore, the fatty acid structure contained in shellac can improve the waterproof and moisture-proof properties of the silica powder, preventing it from easily absorbing water, becoming damp, and clumping, thus affecting its antifreeze performance.

[0208] Comparative Example 4 shows that a durable power optical cable was obtained by replacing the modified silica powder with shellac-coated silica powder and coating the cable core with composite silica powder. The decrease in silica powder content demonstrates that the formation of cross-linked polymers on the silica powder surface has good toughness and impermeability, further reducing the permeability of water molecules. Moreover, the cross-linked polymers have high toughness, which enhances the mechanical strength of the power optical cable.

[0209] Comparative Example 5 shows that replacing composite silicon powder with modified silicon powder coated on the cable core resulted in a durable power optical cable with a decrease in performance. This demonstrates that depositing sheet materials on the surface of modified silicon powder increases the surface roughness of the silicon powder and the contact area between the silicon powder and polyurethane and ethylene glycol, which is beneficial for forming a stable coating layer on the surface of the cable core. On the other hand, the sheet materials can block the penetration of oxygen and water molecules and inhibit the propagation of cracks, thereby improving the aging resistance and mechanical strength of the power optical cable.
