Problems solved by technology

In the process of lubricating oil, the lubricating oil and the surface of the paint film are physically adsorbed. Due to the weak physical adsorption, it is easy to be thrown out or remain in the coil during high-speed winding, which will cause environmental pollution on the job site and may also affect the coil. Electrical Reliability and Stability

Abstract

The invention discloses a double-coated self-lubricating polyurethane enameled wire production process. The production process comprises the following steps: (1) the wire blank is subjected to press machining to form a bare conductor core wire; (2) the bare conductor core wire is cleaned with purified water in the temperature of 60-80 DEC G, and guided into an annealing furnace with a speed of 180-360m / min for protective bright annealing; (3) the surface of the bare conductor core wire is rapidly cooled with purified water in the temperature of 60-80 DEC G, the moisture on the surface of the bare conductor core wire is then wiped off, and then the bare conductor core wire is dried through a drying baker; (4) the bare conductor core wire is guided into an oven painting region with a speed of 180-360m / min, a priming coat is coated through felt or a mould, and then a top coat is coated; wherein the priming coat adopts heat-resistant polyurethane resin, and the top coat adopts self-lubricating improved polyurethane resin; (5) and the enameled wire is cooled after being out from the oven. The production process provided in the invention has advantages of simple production process and stable product parameters, the paint film eccentricity can be reduced, and the subsequent realization of high-speed winding can be facilitated.

Description

technical field [0001] The invention relates to insulated wires and cables, in particular to a production process for double-coated self-lubricating polyurethane enameled wires. Background technique [0002] At present, the traditional enameled wire production is to apply solvent insulating varnish on the surface of the conductor using felt or mold, and then bake at high temperature in the oven to volatilize the solvent of the insulating varnish and cross-link and solidify, and then coat a thin layer of liquid or Solid lubricating oil. In the process of lubricating oil, the lubricating oil and the surface of the paint film are physically adsorbed. Due to the weak physical adsorption, it is easy to be thrown out or remain in the coil during high-speed winding, resulting in environmental pollution on the job site and may also affect the coil. Electrical reliability and stability. Contents of the invention [0003] Aiming at the current state of the art above, the technical...
