Abstract
The invention discloses a water-based lubricant for an enameled wire and a preparation method of the lubricant. The water-based lubricant is used for external lubrication of the enameled wire. The preparation method comprises the following steps: by taking water as a solvent, adding different types of modifiers and dispersants, and dispersing a wax lubricant in an aqueous solution to obtain a homogeneous solution; The water-based lubricant comprises pure water, wax, a modifier and a dispersing aid. Based on the total weight of the water-based wax, the pure water accounts for 70.0-99.25%, the wax accounts for 0.5-30%, the modifier accounts for 0.2-20.0%, and the dispersing agent accounts for 0.05-10.0%. By using the water-based lubricant prepared by the invention, the enameled wire has an excellent static friction coefficient, and the range of the static friction coefficient is 0.03-0.06.
Description
technical field [0001] The invention relates to the technical field of lubricants, in particular to a water-based lubricant for enameled wires and a preparation method thereof. Background technique [0002] As an important electronic special material, enameled wire is widely used in many fields. The market size in 2019 has exceeded 2 million tons. In order to ensure the fast winding of enameled wires, although self-lubricating insulating materials are used, traditional organic solvent-based external lubricants are still applied. The chemical composition of the external lubricant is usually grease, paraffin, natural wax, mixed wax, synthetic wax, etc. The concentration of the prepared solution is generally only about 1%. After coating on the surface of the enameled wire, the solvent will evaporate naturally, leaving an effective lubricant. agent components. According to the calculation of 30-150mg of external lubricating wax / kg of electromagnetic wire, the amount of organi...
