Background
The cable has the purpose of transmitting and distributing electric energy, and is commonly used for urban underground power grids, power station leading-out lines, power supply inside industrial and mining enterprises and transmission lines under river-crossing seawater. In the power line, the specific gravity of the cable is gradually increasing. The operating environment of cable conductor is more complicated various, and some cable conductors need to bury in soil, and some erect in the air. Insulation and corrosion prevention measures are usually required for the cables to avoid potential safety hazards caused by electric leakage and corrosion. The insulation layer of the cable line is usually made of an insulation material, such as: polyvinyl chloride (PVC) insulated cables, rubber cables. For cables used in outdoor severe environments, particularly in humid or strongly acidic and basic environments, the insulating layer of the cable is prone to aging, corrosion and damage, so that power transmission line faults are prone to be caused, and electric shock risks also exist.
At present, there is a need for coating the outer surface of an electric cable with an insulating anticorrosive coating, thereby improving the insulating and corrosion-resistant properties of the electric cable. The existing cable coating is mainly used for insulation, corrosion resistance and fire prevention of cables, and in severe environments, the cables are exposed to long-time sun and rain and are rubbed outside, so that the coating is easy to damage and loses the effects of insulation and corrosion resistance. In addition, the cable with the paint and the cable without the paint are not different in appearance, and the cable is often not clear in distinguishing during the use process, so that the cable without the paint is used in some environments needing to enhance the insulation and corrosion resistance; or in the carrying process, the coating of the cable is scraped off and cannot be found, so that the local insulation and corrosion resistance is reduced, a barrel effect is formed, and the whole section of the cable has weak points. Therefore, an insulating anticorrosive paint for the cable is developed, has stronger wear resistance, can also be convenient for whether the coating is complete or not, and prevents the cable coating from generating leaks, thereby prolonging the service life of the cable.
