Problems solved by technology

[0003] In the desert area, due to the large temperature difference between day and night, the internal optical fiber is easily deformed and bent to affect the signal transmission effect, and there are often strong winds, which easily exposes the optical cable part to direct sunlight and accelerates the aging of the optical cable surface. Therefore, the optical cable is stable for a long time in the desert area. The use of deserts is a problem that must be solved for economic development in desert areas

Abstract

The invention discloses a high-temperature-resistant optical cable and a preparation method thereof, and relates to the technical field of optical cable materials. When the high-temperature-resistant optical cable is prepared, firstly, a polyethylene sleeve optical cable is used as a core material, firstly, a polyethylene sleeve of the core material is softened, high-temperature porous silicon dioxide is embedded, and then the surface of the softened and embedded core material is coated with a modified carbon nanotube mixed solution to form a porous surface layer; and carrying out secondary softening embedding, embedding protein particles into the porous surface layer, and finally carrying out graft modification on the core material subjected to secondary softening embedding by using a fluorescent chelate prepared by reacting neodymium chloride with porphyrin, so as to prepare the high-temperature-resistant optical cable. The high-temperature-resistant optical cable prepared by the invention has good high-temperature resistance and can be stably used in a desert high-temperature environment for a long time.

Description

technical field [0001] The invention relates to the technical field of optical cable materials, in particular to a high temperature resistant optical cable and a preparation method thereof. Background technique [0002] With the development of Internet technology, how to make the transmission of signals between networks more stable and fast has always been the focus of people's attention. Optical cables have light weight, good transmission quality, anti-electromagnetic interference, rich raw material resources, low cost, and corrosion resistance. And other advantages, are widely used in various places. An optical cable is a cable formed by optical fibers through a certain process. The basic structure of an optical cable is generally composed of a cable core, a reinforcing steel wire, a filler, and a sheath. In addition, there are waterproof layers, buffer layers, and insulating metal layers as needed. components such as wires. [0003] In the desert area, due to the large ...
