Problems solved by technology

[0003] In conventional production, enameled wires are produced in ordinary factories, and the requirements for the environment are not so strict, and they are easily polluted by organic silicon in the environment.
And in the process of wire drawing enamelling, the variety or specification production is often switched, which makes the process extremely easy to cause cross-contamination, and the content of silicone cannot be effectively controlled

Embodiment Construction

[0024] In order to better understand the purpose, structure and function of the present invention, a method for manufacturing a low-organosilicon enameled wire of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, the low-organosilicon enameled wire manufacturing method of the present invention includes two steps of wire drawing and enamelling.

[0026] S1, the wire drawing step, the copper billet is drawn with the wire drawing machine and the wire drawing liquid, and the hard bare copper wire of the required specification is obtained. Specifically, a low-oxygen copper billet with a diameter of 8.0mm is used to obtain a hard bare copper wire with a diameter of 0.060-0.100mm through the processes of large drawing, medium drawing, small drawing, fine drawing, and micro drawing.

[0027] S2, a step of wrapping varnish, wrapping the insulating layer on the bare wire.

Abstract

The invention discloses a manufacturing method of a low-organosilicone enameled wire, which comprises the following steps of: enameling: wrapping an insulating layer on a bare wire, wherein the enameling step comprises the following steps: a painting process: coating insulating paint on the bare wire; and a baking process: evaporating the solvent through baking, and curing the paint base into a film to form an insulating layer; meanwhile, heating and cracking organic silicon, and discharging the organic silicon in a gas form. Compared with a conventional production mode, the manufacturing method of the low-organosilicone enameled wire can effectively control organic silicon from being mixed into the enameled wire from the environment, the process is optimized and controlled, and the influence of external organic silicon on production is effectively avoided.

Description

technical field [0001] The invention belongs to the field of enameled wire manufacturing technology, and in particular relates to a method for manufacturing low-organosilicon enameled wire. Background technique [0002] For example, if there are silicon-based substances (such as silicone rubber, silicone oil, silicon-based coating agents, silicon fillers, etc.) in sealed electrical appliances such as relays, they will produce volatile gases containing silicon, which may cause silicon to adhere to the contacts and cause poor contact. Relays cause failure or shortened life. Therefore, the requirements for organic silicon in airtight relays are very strict, and the technical requirements of 0.5ppm must be met. [0003] In conventional production, enameled wires are produced in ordinary factories, and the requirements for the environment are not so strict, and they are easily polluted by organic silicon in the environment. And in the process of wire drawing enamelling, the var...
