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

Abstract

The invention relates to high-flame-retardant enameled wire lubricating oil. The lubricating oil is prepared from, by weight, 93.5-97.5% of flame-retardant base oil, 0.5-2.0% of higher fatty acid ester, 1.5-3.0% of isoparaffin and 0.5-1.5% of siloxane. The invention also provides a preparation method of the high-flame-retardant enameled wire lubricating oil. The preparation method comprises the following steps: mixing the flame-retardant base oil, higher aliphatic ester, isoparaffin and siloxane to obtain a mixture; and heating and stirring the obtained mixture to obtain the high-flame-retardant enameled wire lubricating oil. The lubricating oil is applied to coating of the surface of an enameled wire with lubricating oil, has the advantages of good lubricating effect and low static friction coefficient, and is suitable for production of a high-speed full-automatic inductance winding machine; when encountering electronic sparks and open fire, the lubricating oil is not easy to burn, good in thermal oxidation resistance and high in safety; the lubricating oil makes the surface of the enameled wire smoother and the insulating property of the enameled wire better ensured; and all component raw materials are supplied by commercially available commodities, the preparation method is simple and convenient, and the cost is low.

Description

technical field [0001] The invention relates to an enameled wire lubricating oil and a preparation method thereof, in particular to a high flame-retardant enameled wire lubricating oil and a preparation method thereof. Background technique [0002] In the enameled wire manufacturing process, after the copper wire is coated with insulating varnish and cured, it is also necessary to coat a layer of lubricating oil on the surface to facilitate the protection of the insulating varnish film when it passes through the winding machine guide wheel and other components during the coil winding operation. Damaged and not easy to break. The traditional enameled wire surface lubricating oil uses 120# rubber solvent as a diluent (95%-99% by mass) to dissolve paraffin and mineral oil (1%-5% by mass) and coat it on the surface of the enameled wire. After the 120# rubber solvent volatilizes , Paraffin and mineral oil are attached to the surface of the wire to lubricate. The 120# rubber sol...
