Problems solved by technology

[0003] Although the aluminum alloy cable has good thermal conductivity and cutting performance, which makes up for the deficiency of the copper cable and reduces the weight of the cable, the aluminum alloy material is relatively active, and the oxide film naturally formed on the surface is thinner in the ordinary atmospheric environment. , generally only 0.01-0.1μm, resulting in poor corrosion resistance and short service life of aluminum alloy cables in environments with severe pollution, high humidity, and coastal areas

preparation example 1

[0037] A modified asbestos fiber, which is prepared by the following method:

[0038]According to the dosage in Table 1, mix asbestos fiber, polytetrafluoroethylene dispersion and sodium dibutylnaphthalene sulfonate, heat to molten state, stir for 10-15min, cool to 23±2°C to obtain modified asbestos fiber.

preparation example 2-3

[0040] The preparation method and raw material types of the modified asbestos fiber of Preparation Example 2-3 are exactly the same as those of Preparation Example 1, the difference is that the dosage of each raw material is different, as shown in Table 1 for details.

[0041] Each raw material dosage (unit: kg) of the modified asbestos fiber of table 1 preparation example 1-3

[0042] raw material Preparation Example 1 Preparation example 2 Preparation example 3 asbestos fibers 10 15 20 PTFE dispersion 8 8 8 Sodium Dibutyl Naphthalene Sulfonate 5 5 5

Embodiment 1

[0044] The aluminum alloy cable of Example 1 is obtained through the following steps:

[0045] According to the dosage in Table 2 and Table 3, the preparation of the cable core: melting iron, copper, magnesium and aluminum at 1450 ° C, degassing, cooling to 23 ° C, casting into the shape of aluminum strips, rolling, drawing Aluminum alloy monofilament, twisted, annealed at 300°C for 6 hours, cooled to 23°C to obtain a cable core;

[0046] Melt fluororubber particles at 230°C, then add nano-tin dioxide, nano-zinc oxide, graphene microflakes, mica powder, stearic acid, vulcanizing agent and antioxidant, and knead at 45°C for 15 minutes. vulcanization to obtain the sheath blend material, extrude the sheath blend material and wrap it on the outside of the cable core to obtain an aluminum alloy cable.

Abstract

The invention relates to the field of aluminum alloy cables, and particularly discloses a corrosion-resistant aluminum alloy cable and a preparation method thereof.The corrosion-resistant aluminum alloy cable is composed of a cable core and a sheath arranged outside the cable core in a sleeving mode; the sheath is prepared from the following raw materials in parts by weight: fluororubber particles, nano tin dioxide, nano zinc oxide, graphene nanoplatelets, mica powder, stearic acid, a vulcanizing agent and an antioxidant. The optimal tensile strength and the optimal elongation at break of the aluminum alloy cable treated by the oxalic acid solution are-4.2% and 13.0% respectively, the optimal tensile strength and the optimal elongation at break of the aluminum alloy cable treated by the sodium hydroxide solution are-3.4% and 12.5% respectively, and the corrosion resistance of the aluminum alloy cable is improved.

Description

technical field [0001] The present application relates to the field of aluminum alloy cables, more specifically, it relates to a corrosion-resistant aluminum alloy cable and a preparation method thereof. Background technique [0002] Aluminum alloy cable is a new type of material cable obtained by using AA8030 series aluminum alloy as the conductor and adopting advanced technologies such as special roll forming and stranding production process and annealing treatment. It is mainly used for transmission and distribution of electric energy, and is widely used in Urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. [0003] Although the aluminum alloy cable has good thermal conductivity and cutting performance, which makes up for the deficiency of the copper cable and reduces the weight of the cable, the aluminum alloy material is relatively active, ...
