Problems solved by technology

Acid, alkali and saline solutions are immersed in the cable, and the cable cannot continue to be used
Moreover, under the low temperature environment, the mechanical properties of polyethylene materials will change greatly or even freeze cracks, making it difficult to achieve the protective effect. Based on this, how to invent a cold-resistant and corrosion-resistant cable is particularly important.

Abstract

The invention discloses an aluminum alloy cable and a preparation method thereof, and relates to the technical field of cables. According to the invention, 1-(4-amino-phenyl)-propane-1, 2, 3-triol is firstly utilized to modify the wrapped polyethylene insulating layer, so that the low-temperature range of polyethylene is widened, and the cable has low-temperature resistance; then extrusion molding foaming treatment and irradiation heating treatment are carried out, a polystyrene-polypyrrole foam layer is formed on the surface of the modified insulating layer, under long-time illumination, polypyrrole absorbs light energy and converts the light energy into heat energy, the temperature of the cable rises, under continuous heat preservation of the foam layer, the cable keeps certain heat for a long time, and therefore the cold-resistant effect of the cable is improved; and then a film preparation process is carried out twice, and a compact multi-element metal protection film is formed on the surface of the insulating foam layer, so that invasion of a corrosive medium is effectively isolated, and the cable has a corrosion-resistant effect. The prepared aluminum alloy has the cold-resistant and corrosion-resistant effects.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aluminum alloy cable and a preparation method thereof. Background technique [0002] With the rapid development of economy, wires and cables are widely used in various industries and fields, especially in areas with bad climate and special environment, which have extremely high requirements for cables, radiation resistance, cold resistance, high temperature resistance, etc. are necessary. condition. [0003] At present, the existing cables are generally made of polyethylene plastics. Because the plasticizers are easily swelled and hydrolyzed under the corrosion resistance of chemicals and oils, the insulating plasticizers are finally converted into conductive plasticizers. The soft polyethylene plastic gradually loses its electrical insulation, and eventually the plastic is hard and brittle, cracked and swelled. Acid, alkali and salt solution are immersed in the cable, and th...
