Abstract
The invention discloses a cold-resistant high-flame-retardant ultraviolet-resistant PVC sheath material for a 5G photoelectric composite cable and a preparation method thereof, wherein the raw materials of the PVC sheath material for the 5G photoelectric composite cable comprise the following components in parts by weight: PVC resin, a plasticizer, an environment-friendly calcium-zinc composite heat stabilizer, an antioxidant, oxidized polyethylene wax, a lubricant, an ethylene terpolymer, chlorinated polyethylene, a self-made composite flame retardant, vinyl chloride-vinyl acetate copolymer resin and a methyl methacrylate processing aid. The PVC sheath material applicable to the 5G photoelectric composite cable not only ensures the transmission of communication signals from transmission equipment to a core network area and the transmission of power energy, but also can meet the safety requirements of a communication base station on the outdoor harsh environments such as narrow space laying, high and low temperature circulation, high humidity, strong ultraviolet rays and the like and the flame retardance of bundled cables.
Description
Technical Field
The invention relates to the technical field of high polymer materials for wires and cables, in particular to a cold-resistant high-flame-retardant ultraviolet-resistant PVC sheath material for a photoelectric composite cable suitable for a 5G communication base station and a preparation method thereof.
Background
With the rapid development of the scientific and technological society, the photoelectric composite transmission technology is more and more widely applied in real life. However, in the conventional environment, transmission means of electric energy and transmission means of communication signals are different, and when electric energy or communication signals are transmitted independently, the two types of energy do not interfere with each other. In the 5G era, the photoelectric composite cable integrates electric energy and communication signal transmission, so that the problems of electric energy requirements of 5G equipment and the like and communication signal transmission can be effectively solved, and laying space and cost can be saved, so that compared with the transmission scene of traditional electric energy and communication signals, the transmission scene of the 5G communication base station is increasingly required by the photoelectric composite cable, and meanwhile, higher safety requirements are also provided.
Due to unattended operation of the outdoor communication base station, in consideration of cost and working efficiency of base station installation, maintenance and management, the photoelectric composite cable adopts the PVC base material as a sheath material, and compared with a halogen-free low-smoke polyolefin material, the photoelectric composite cable has the advantages of flexibility, high and low temperature resistance (-40 ℃ -105 ℃), flame retardance, ultraviolet resistance, high-speed extrusion and the like, can meet the conventional requirements of cables, and can also meet the characteristics of compact structure, small space occupation, high transmission efficiency and high safety of the photoelectric composite cable of the 5G communication base station. The invention relates to a novel cold-resistant high-flame-retardant ultraviolet-resistant PVC sheath material for a 5G photoelectric composite cable and a preparation method thereof.
At present, PVC resin powder is generally adopted as a base material of the conventional PVC material, dioctyl terephthalate, dioctyl phthalate, trioctyl trimellitate, epoxy soybean oil and the like are adopted as plasticizers to improve the flexibility of the PVC material, but the application environment requirement of the 5G photoelectric composite cable on the sheath material at minus 40-105 ℃ is difficult to realize due to the contradiction of high and low temperature resistance. Meanwhile, the material cost is greatly increased by adopting the traditional materials such as nitrile rubber and the like, and the mechanical property and the temperature resistance grade of the material are not improved. In addition, the shell forming performance of the sheath material during combustion cannot be reflected by adopting conventional common flame retardants such as antimony trioxide and magnesium hydroxide, so that the flame retardant performance of the whole photoelectric composite cable fails.
