Problems solved by technology

[0004] Microbial corrosion is a kind of electrochemical corrosion, the difference is that the medium is changed due to the reproduction and metabolism of corrosion microorganisms and some physical and chemical properties of the interface in contact with it, the secretion of intermediate products and / or final products of microbial cell metabolism Both substances and external enzymes can cause the failure of the communication tube material and cannot protect the cable. Therefore, it is necessary to develop a communication tube with antibacterial and anti-corrosion functions.

Abstract

The invention relates to the technical field of communication tubes, especially to an antibacterial anti-corrosion communication tube and a preparation method thereof. The antibacterial anti-corrosioncommunication tube in the invention comprises a communication tube body, wherein an antibacterial layer is arranged on the outer surface of the communication tube body; the antibacterial layer contains antibacterial particles; and the antibacterial particles are prepared by taking iron-doped zinc oxide as a carrier, loading copper nanoparticles on the carrier and then loading silver / carbon nanodot composite particles, the iron-doped zinc oxide is of a porous structure, and a molar ratio of silver to copper in the antibacterial particles is 0.05-0.08. According to the antibacterial anti-corrosion communication tube, the antibacterial layer is arranged on the outer surface of the communication tube, so microorganisms on the surface of the communication tube can be inhibited and even killed,and thus, the internal communication tube body is protected, and the probability of microbial corrosion of the communication tube is reduced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of communication tubes, in particular to an antibacterial and anti-corrosion communication tube and a preparation method thereof. Background technique [0002] With the development of social economy, the communication industry is developing faster and faster, which makes the development of the supporting communication tubes faster and faster. At present, most of the communication pipes on the market are plastic pipes made of polymer materials, because polymer materials have light weight, non-flammability, high chemical resistance, good electrical insulation performance, stable physical and chemical properties, and low price It has a very important position in industrial production and is widely used in industries, agriculture, transportation, construction, electronic communications, household appliances, furniture, packaging, and medical and health fields. [0003] However, since the polymer material itself...
