Problems solved by technology

[0003] At present, many enameled wires used in motors and electrical appliances usually need to use solvents in the preparation process, and the harmful substances in the solvents will cause certain pollution to the environment.
In addition, due to the ordinary performance of the coated insulating material and the unreasonable preparation process, the heat resistance of many enameled wires is not good enough. The insulation thickness is thick and the surface is rough, which not only cannot meet the toughness requirements of the winding, but also cannot Improve the technical and economic indicators of motors and electrical appliances

Abstract

The invention discloses a novel inorganic insulation enameled wire. The novel inorganic insulation enameled wire comprises a nickel plating copper wire and a glass thin film which covers the nickel plating copper wire. The novel inorganic insulation enameled wire is manufactured through a film drawing method, the diameter of the nickel plating copper wire is 2mm, and the thickness of the glass thin film ranges from 50 micrometers to 100 micrometers. The surface of the enameled wire is compact and smooth, the novel inorganic insulation enameled wire has the small insulation thickness and good electrical insulation performance and heat resistance, and a manufacturing method of the novel inorganic insulation enameled wire is simple, low carbon and environmentally friendly, and can completely meet the flexible requirement for winding.

Description

technical field [0001] The invention belongs to an insulating enameled wire, in particular to a novel inorganic insulating enameled wire, and belongs to the technical field of insulating materials. Background technique [0002] Enameled wire is an indispensable key supporting raw material for motors, electrical appliances and other products. It is generally obtained by repeatedly coating insulating varnish on round or special-shaped metal wires. Therefore, the performance of insulating materials directly affects the application of enameled wire. value. In recent years, with the continuous improvement of the level of science and technology, on the one hand, it is required to modify the existing motors and electrical appliances to reduce the size and weight, and improve the technical and economic indicators; on the other hand, it is required to develop large-capacity motors and electrical appliances. All require high-performance high-temperature-resistant insulated enameled w...
