Abstract

The invention belongs to the technical field of lubricating oil and in particular relates to lubricating oil for an enamel wire, v ngtfused for processing the enamel wire and a preparation method of the lubricating oil. The lubricating oil is prepared from the following raw materials in parts by weight: 80-100 parts of D40 solvent oil, 0.5-1.5 parts of paraffin, 0.4-0.6 part of synthetic wax, 0.4-0.6 part of beeswax, 1-3 parts of cyclohexane and 0.1-0.2 part of stearic acid. According to the lubricating oil disclosed by the invention, the components are reasonable in proportion, the preparation method is simple and feasible, and the prepared lubricating oil is small in friction coefficient, so that the processed enamel wire is low in breakage rate. The lubricating oil is particularly suitable for the enamel wires with small wire diameters, can adopt high wire winding speed in the production process and is capable of greatly improving the production efficiency and lowering the production cost.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a lubricating oil for enameled wire used for enameled wire processing and a preparation method thereof. Background technique [0002] As a winding wire, enameled wire is one of the most basic electrical materials, and has a large market space as a supporting product for the electronics and electrical industries. Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. The bare wire is annealed and softened, and then painted and baked many times. Due to the friction between the enameled wire and mechanical equipment (guide wheel, mold, winding machine parts, etc.) into a tight, applicable coil. [0003] Therefore, it is necessary to coat a layer of lubricating oil on the outside of the enameled wire during the process of painting, baking, and winding to ensure a small friction coefficient between the enameled wire ...
