Problems solved by technology

[0003] There are many classifications of enameled wires. According to the different materials of their conductors, they can be divided into copper wires, aluminum wires, copper-clad aluminum wires, etc.; according to different uses, they can be divided into oily enameled wires, polyester enameled wires, and modified polyester enameled wires. , polyurethane enameled wire, etc., the processing technology is simple, but there are many processes, and improper control of each link will cause poor adhesion of the surface paint, unstable coating, or even peeling off, which will affect the production quality and quality of the enameled wire. service life

Abstract

The invention belongs to the technical field of enameled wire production technologies, and particularly relates to a processing technology of a copper enameled wire with high painting fastness. The processing technology specifically comprises the steps of wire drawing, paying off, annealing, cleaning, painting, baking and curing, and taking up. Wire drawing and paying off are carried out for many times to obtain a copper wire, then the cooper is annealed, and the annealed copper ispolished and cleaned to remove surface burrs of the copper wire and increase the surface roughness, so paint adhesion is facilitated; and the paint and the surface of the copper wire are tightly and uniformly bonded through multiple times of painting and two times of pressurization, meanwhile, drying of the surface of the paint is accelerated by increasing the temperature in a pressurization machine, and finally the paint is more stable through baking and curing, so the prepared enameled copper wire is uniform and stable in paint layer, high in fastness, not easy to fall off and high in breakdown strength.

Description

technical field [0001] The invention belongs to the technical field of enameled wire production technology, and in particular relates to a copper enameled wire processing technology with high paint fastness. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, thermal properties four major properties. Enameled wire is a kind of electromagnetic wire, which is widely used in windings and components of electrical products such as moto...
