Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 A special polyurethane self-adhesive twin-core wire is shown, which includes two parallel conductors 1, an insulating layer is provided on the outside of the conductors, and a polyurethane insulating layer 2 and a polyamide self-adhesive layer are sequentially provided on the insulating layer from the inside to the outside. Layer 3. A lubricating oil layer is arranged outside the polyamide self-adhesive layer.

[0026] A process for making a special polyurethane self-adhesive twin-core wire is characterized in that it comprises the following steps:

[0027] (1) Select two plates of 0.100mm copper billet, after being released by an independent pay-off system, annealing is carried out in an annealing furnace at about 500 degrees to remove the stress on the surface of the copper conductor, soften the copper conductor, and make it have a...

Abstract

The invention relates to a special polyurethane self-adhesive double-core wire and a manufacturing process thereof. At present, instruments and transmission wires for detection are affected by severemarine environment, and a corrosion phenomenon often occurs in a short time. And the development of the deep sea detection technology in China is hindered to a certain extent. The self-adhesive double-core wire comprises two parallel conductors, an insulating layer is arranged outside each conductor, and each insulating layer is sequentially provided with a polyurethane insulating layer and a polyamide self-adhesive layer from inside to outside. And a lubricating oil layer is arranged outside the polyamide self-adhesive layer. The wire has good salt resistance, and electrical performance reduction caused by seawater corrosion is prevented.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to a special polyurethane self-adhesive double-core wire and a manufacturing process thereof. Background technique [0002] The vast ocean, especially the deep sea, is getting more and more attention from our country's marine science and technology personnel. The main goal is to focus on seeking strategic resources, vigorously develop deep-sea technology, continue to carry out deep-sea exploration, establish deep-sea industries in a timely manner, and enhance my country's international competitiveness in discovering, delineating and developing deep-sea resources. However, detection instruments and transmission wires are affected by the harsh environment of the ocean, and corrosion often occurs in a relatively short period of time. To a certain extent, it hinders the development of my country's deep-sea exploration technology. Contents of the invention [0003] Aiming at the shortc...
