Embodiment 1
[0040] refer to figure 1 As shown, this embodiment discloses a rodent-proof, monkey-proof and lightning-proof radio frequency remote optical cable for a base station, which includes: an optical fiber 1, a PBT tight sleeve material 2 sleeved outside the optical fiber 1, Aramid fiber reinforcement 3, central sub-cable sheath layer 4, water blocking tape 5, steel tape armor layer 6, outer sheath layer 7.
[0041] In this embodiment, PBT is used as the tight sleeve layer for the optical fiber protective layer. PBT is polybutylene terephthalate. This material has strong tensile strength, bending strength, and impact strength, and is less affected by environmental changes. And other characteristics, compared with nylon material, the process performance is stronger, the processing temperature is wider, and the cost is lower.
[0042] The steel strip pattern longitudinal armoring enhances the tensile strength, compressive strength and anti-corrosion ability of the optical cable. When...
Embodiment 2
[0052] The structure of the optical cable in Example 2 is the same as that in Example 1, except that the PBT material includes: 80 parts of PBT, 20 parts of glass fiber, 6 parts of synergistic flame retardant system, and 10 parts of flame retardant and toughening system. parts, 1.5 parts of lubricants, 1.5 parts of dispersants, 0.8 parts of antioxidants, and 0.5 parts of antibacterial agents.
[0053] The synergistic flame retardant system includes polyphenylene sulfide and aluminum diethylphosphinate, and the mass fraction ratio of the polyphenylene sulfide and aluminum diethylphosphinate is 1.5:1.
[0054] The flame retardant and toughening system includes: 1 part of antimony trioxide, 0.2 part of sodium silicate, 2.5-4 parts of sodium bicarbonate, 0.8 part of POE, 0.1 part of calcium dodecylbenzenesulfonate, ethylene-acrylic acid methyl 1 part of ester-glycidyl methacrylate terpolymer.
Embodiment 3
[0056] The PBT tight sleeve material in this embodiment includes: 90 parts of PBT, 25 parts of glass fiber, 12 parts of synergistic flame retardant system, 15 parts of flame retardant and toughening system, 2 parts of lubricant, 2 parts of dispersant, 1 part of antioxidant part, 0.8 part of antibacterial agent.
[0057] The synergistic flame retardant system includes polyphenylene sulfide and aluminum diethylphosphinate, and the mass fraction ratio of the polyphenylene sulfide and aluminum diethylphosphinate is 1.5:1.
[0058] Specifically, in parts by weight, the flame retardant and toughening system includes: 1.5 parts of antimony trioxide, 0.4 parts of sodium silicate, 4 parts of sodium bicarbonate, 1.3 parts of POE, calcium dodecylbenzenesulfonate 0.8 parts, 3 parts of ethylene-methyl acrylate-glycidyl methacrylate terpolymer.
