Lubricating oil for varnished wires and application thereof

Abstract

The invention discloses lubricating oil for varnished wires and an application thereof. The lubricating oil for the varnished wires comprises the following components: 1-3% of methyl silicone oil, 2-5% of 848 lubricating oil, and the balance being 3GS machine oil, wherein the percentage is the mass percentage. The obtained lubricating oil for the varnished wires is not easy to burn while meeting electronic sparks or open fire, and has quite high safety; the obtained lubricating oil has low coefficient of friction, thereby allowing the wire breaking rate to be low, quickening the pay-off speed during production, and allowing the yield to be greatly improved; the obtained varnished wires have more smooth and more bright surfaces, and the insulation performance of the varnished wires can be also better ensured; and the cost is low.

Description

technical field [0001] The invention relates to an enameled wire lubricating oil and its application. 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. Since there is friction between the enameled wire and mechanical equipment during winding, the enameled wire itself not only needs to have sufficient mechanical strength, but also its surface should be smooth enough, so that the enameled wire can be smoothly wound into a tight and suitable coil. [0003] Lubricants are used in the production of enameled wires to make the wires neat and tight. At present, in the production of enameled wires in my country, kerosene and transformer oil are mostly used as lubricants on the surface of the insulating layer. With the continuous improvement of the winding machine, its winding speed has been continuously increased, from t...

AI Technical Summary

Problems solved by technology

With the continuous improvement of the winding machine, its winding speed has been continuously increased, from the original 4000 rpm to 12000-15000 rpm, and there are higher requirements for the wear resistance of the enameled wire. The original lubricating oil is gradually unable to meet the requirements.

It is also useful to dissolve paraffin in gasoline as the lubricating oil on the surface of enameled wire. Although the lubricity of enameled wire has been greatly improved, the solubility of paraffin is not good, and precipitation is prone to precipitation. Such enameled wire dissolves in the coil when it is wound Wax accumulation, resulting in disconnection
