Description

Enameled wire lubricating oil and preparation method thereof
Technical field
The invention belongs to technical field of lubricating oil, more particularly to a kind of enameled wire lubricating oil for enameled wire machining and Its preparation method.
Background technology
Enameled wire is one of most basic electrical material as winding wire, as the product supporting with electronics, electrical apparatus industry With the very big market space.Enameled wire is a principal item of winding wire, is made of conductor and insulating layer two, bare wire warp After annealing softening, then repeatedly japanning, baking form process.Enameled wire and mechanical equipment (guide wheel, mould, coiling during due to coiling Machine part etc.) between there is friction, thus enameled wire will not only have enough mechanical strengths in itself, and smooth enough is also wanted on its surface, Enameled wire so could be turned to successfully to close, applicable coil.
Therefore it is both needed in enamelled wire paint, baking, winding process in one layer of lubricating oil of its outer application, to ensure enamel-cover A less friction coefficient is kept between line and mechanical equipment.Current existing enameled wire lubricating oil is due to component and a group / proportioning it is unreasonable, when causing to use existing enameled wire oil lubrication enameled wire, enameled wire and mechanical equipment Between friction coefficient it is larger, it is impossible to meet the lubrication needs of thinner enameled wire, often result in thinner enameled wire in japanning, dry Roasting, coiling drawing process in, due to larger with the direct frictional force of mechanical equipment, there is situation about breaking, influence to be produced Enameled wire quality and production efficiency.
The content of the invention
It is an object of the invention to overcome existing for existing enameled wire lubricating oil due to lubricating oil component and group distribution It is more excessive than unreasonable caused friction coefficient, the problem of enameled wire lubricated easily breaks, and a kind of recipe ingredient and group are provided Distribution ratio is reasonable, and preparation method is simple and practicable, and friction coefficient is small, is especially suitable for the enameled wire profit of smaller line footpath enameled wire Lubricating oil and preparation method thereof.
