Problems solved by technology

[0002] Cables installed outdoors are prone to UV aging degradation due to prolonged exposure to sunlight, resulting in cracks on the surface of the cable sheath. Cracking of the cable sheath will cause water vapor and foreign matter, etc. Intrusion into the interior of the cable, thereby affecting the normal operation of the cable; in addition, the heat brought by a large amount of infrared rays contained in sunlight will also increase the surface temperature of the cable, further aggravating the aging degree of the cable itself, and finally reducing the cable cable life

Abstract

An anti-aging cable is provided, a surface of a cable sheath is coated with an abrasion-resistant heat-reflective coating, the wear-resistant heat-reflective coating adopts a fluorocarbon emulsion asa base material, the coating itself has excellent water resistance, weathering resistance and contamination resistance. In addition, nano-zinc oxide doped with aluminum, nano-alumina and nano-silica composite powder are used as functional additives, so that the surface layer of the cable has good weathering resistance, wear resistance, ultraviolet shielding and infrared reflection properties, andthe service life of the cable is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aging-resistant cable. Background technique [0002] Cables installed outdoors are prone to UV aging degradation due to prolonged exposure to sunlight, resulting in cracks on the surface of the cable sheath. Cracking of the cable sheath will cause water vapor and foreign matter, etc. Intrusion into the interior of the cable, thereby affecting the normal operation of the cable; in addition, the heat brought by a large amount of infrared rays contained in sunlight will also increase the surface temperature of the cable, further aggravating the aging degree of the cable itself, and finally reducing the cable cable life. Contents of the invention [0003] In view of the above existing technical problems, the object of the present invention is to provide an aging-resistant cable with a certain ultraviolet and infrared blocking effect, so as to achieve the purpose of prolonging th...
