Abstract

The invention relates to the technical field of chemical manufacturing, in particular to a rodent-proof indoor optical fiber outer sheath material and a preparation method thereof, the raw materials of which include the following components: polybutylene terephthalate, phenyl salicylate, alginic acid Sodium, polyethylene, magnesium hydroxide, calcium stearate, antioxidant, chlorinated paraffin, polyether modified silicone oil and rodent repellant; first, add chlorinated paraffin and polyether modified silicone oil to cooperate with each other in the raw material of the present invention It can reduce the surface tension of the outer sheath material of the optical fiber in the rodent-proof room, improve the waterproof and impervious ability, and also improve its flame retardancy and insulation; secondly, the rodent-proof agent is added in the raw materials of the present invention, which is composed of inverted pot powder and Linglong grass Composed of limestone powder and limestone powder, it has a special smell and can repel rats and other harmful animals from destroying the outer sheath material of the rodent-proof indoor optical fiber; at the same time, the rodent-proof powder of Linglong grass can also poison rats and other harmful animals to death.

Description

technical field [0001] The invention relates to the technical field of chemical manufacturing, in particular to a rodent-proof indoor optical fiber outer sheath material and a preparation method thereof. Background technique [0002] Optical fiber is a light transmission tool that utilizes the principle of total reflection of light in fibers made of glass or plastic. The tiny fiber is encapsulated in a plastic sheath that allows it to be bent without breaking. Typically, a transmitter at one end of the fiber uses a light-emitting diode or a laser to send pulses of light into the fiber, and a receiver at the other end of the fiber uses a photosensitive element to detect the pulses. In daily life, optical fibers are used for long-distance information transmission because the loss of light in optical fibers is much lower than that of electricity in wires. However, there are still many problems in the use of optical fibers: first, the existing optical fiber outer sheath materi...
