Anti-rat and anti-bird pecking optical cable

Abstract

The invention discloses a ratproof and bird-damage-prevention optical cable. An inner sheath is made of a material prepared from the following ingredients of 60 to 70 parts of nitrile rubber buna, 50to 60 parts of epoxy resin, 20 to 30 parts of modified fluorinated polyurethane, 5 to 10 parts of auxiliary agents, 2 to 5 parts of antioxidants and 1 to 2 parts of nanometer titania-based antibacterial agents; an outer sheath is made of a material prepared from the following ingredients of 50 to 70 parts of crosslinked polyethylene, 10 to 20 parts of ethylene propylene rubber, 5 to 15 parts of glass fiber, 5 to 10 parts of polyether sulfone, 15 to 25 parts of modified nanometer aluminum hydroxide composite flame retardants, 2 to 5 parts of antioxidants, 2 to 5 parts of anti-ultraviolet agentsand 5 to 10 parts of auxiliary agents. The ratproof and bird-damage-prevention optical cable has the advantages that the inner sheath structure is used; good waterproof, dampproof and mildewproof characteristics are realized; the service life of the optical fiber is prolonged.

Description

technical field

[0001] The invention relates to the communication field, in particular to a rodent-proof and bird-pecking-proof optical cable. Background technique

[0002] There are two types of optical cable designs for traditional rodent and bird protection: chemical methods and physical methods. The chemical method is generally to add repellants such as capsicum to the outer sheath material, so that rodents and birds do not like to damage the outer sheath of the optical cable, thereby protecting the optical cable from damage; or the outer sheath Designed with colors that birds do not like, etc., but these methods have limited effects, and are likely to cause pollution to the production and use environment, and the taste of capsicum will weaken or even disappear over time, and the warning color will age and fade, making the protective effect more effective. It's getting worse. The physical method is generally to add a metal protective layer such as round steel wire spir...
