A kind of high flame retardant enameled wire lubricating oil and preparation method thereof

Abstract

The invention relates to a high flame-retardant enameled wire lubricating oil, which comprises the following raw material components by weight percentage: 93.5-97.5% of flame-retardant base oil, 0.5-2.0% of high-grade fatty acid ester, 1.5-3.0% of isoparaffin, Siloxane 0.5‑1.5%. The present invention also provides a preparation method of highly flame-retardant enameled wire lubricating oil, comprising the following steps: mixing flame-retardant base oil, higher fatty acid ester, isoparaffin, and siloxane to obtain a mixture; heating the obtained mixture, Stir to obtain high flame retardant enameled wire lubricating oil. The lubricating oil of the present invention is applied to lubricating oil coating on the surface of enameled wires, has the advantages of good lubricating effect and low static friction coefficient, and is suitable for the production of high-speed automatic inductance winding machines; it will not easily burn when encountering electronic sparks or open flames, and has good thermal oxidation resistance , high safety; the surface of the enameled wire is smoother, and the insulation performance of the enameled wire is better guaranteed; the raw materials of each component are commercially available, and the preparation method is simple and the cost is low.

Description

Technical field [0001] The present invention relates to an enameled wire lubricating oil and a preparation method thereof, specifically to a high flame retardant enameled wire lubricating oil and a preparation method thereof. Background [0002] In the enameled wire manufacturing process, after the copper wire is coated with insulation paint and cured, it is also necessary to coat a layer of lubricating oil on the surface to facilitate the protection of the insulating paint film from damage and not easy to break the wire when the coil is wrapped around the production industry through components such as winding machine guide wheels. The traditional enameled wire surface lubricating oil is coated with 120# rubber solvent as a diluent (mass ratio of 95%-99%), dissolved paraffin wax, mineral oil (mass ratio of 1%-5%) coated on the surface of enameled wire, 120# rubber solvent volatilization, paraffin wax and mineral oil attached to the surface of the wire to play a lubricating role. ...

AI Technical Summary

Problems solved by technology

The 120# rubber solvents used in traditional lubricating oils are all light and volatile petroleum solvents. These solvents will all volatilize into the air, affecting environmental protection, and human inhalation will affect health. In addition, these light petroleum solvents have a low flash point and are volatile Inflammable and explosive items, there are certain risks in the process of storage and use; and the solubility of paraffin is not good, and it is easy to precipitate. Such enameled wires are prone to wax accumulation when winding coils, so they are easy to break
