Novel environment-protection, rat-proof and ant-proof optical cable and processing technology thereof

Abstract

An environment-protection, rat-proof and ant-proof optical cable comprises a cable core and a sheath layer of a three-layer structure, wherein a steel strip or steel wire layer (3), a regeneration polyethylene material protection layer (2) and a nylon protection layer (1) are sequentially arranged from inside to outside, and the regeneration polyethylene material protection layer (2) is tightly attached to the nylon protection layer (1). The invention further relates to the technology for producing the environment-protection, rat-proof and ant-proof optical cable. Nylon adopted in one of the heath layer so that the environment-protection, rat-proof and ant-proof optical cable is good in rigidity and toughness. In addition, the corresponding processing technology is provided, compensation is carried out aiming at self defects of nylon, and the produced optical cable can prevent rats and ants efficiently. Simultaneously, the optical cable is low in cost, and the technical problem existing in the prior art is solved.

Description

technical field [0001] The invention relates to an optical cable, in particular to an environment-friendly, rodent-proof and ant-proof optical cable and its processing technology. [0002] Background technique [0003] Anti-rodent and ant-proof optical cable, as the name suggests, is to prevent the optical cable from being attacked by rodents such as mice and termites. At present, some special occasions of directly buried optical cables and duct optical cables are often bitten by rodents, which brings great troubles to the design and maintenance of optical cables. [0004] As a kind of rodent with strong reproduction and vitality, mice live widely in various regions of the world. Because their incisors are well developed and will continue to grow, mice have the habit of biting objects to keep their teeth sharp. The unique smell of plastic Make it a frequent gnawing target for rodents. Optical cable manufacturers have changed the design of anti-rodent optical cable from th...

The method of adding spicy agent to prevent rodents, that is to say, in the production process of optical cable material kneading and granulation, adding spicy agent, this method of rodent prevention, it will produce a pungent smell when the extrusion sheath is produced, to a certain extent It affects the health of production personnel in the workshop. During the construction process, it is necessary to wear protective gloves to prevent the hands from directly touching the optical cable and causing a burning sensation. This is contrary to the people-oriented and healthy production in today's society; Migrate and volatilize in the sheathing material, so it is difficult to guarantee the rodent-proof effect and effective time of the optical cable sheathing material containing spicy agent

Using multi-layer armor, after the mouse bites off the outer sheath, the steel strip and steel wire will rust away in a few years, and finally it will not be able to prevent rats and termites; at the same time, due to the armored steel wire of the optical cable, it cannot effectively prevent Electrical damage, large outer diameter, heavy weight, not soft, difficult to manufacture, and inconvenient for engineering construction
