Fabrication process for enameled wire taking waterborne insulation paint as insulation layer

Abstract

The invention discloses a fabrication process for an enameled wire taking waterborne insulation paint as an insulation layer. The fabrication process comprises the following steps of A, unwinding, inwhich a wire is uniformly payed off from a wire shaft; B, cleaning, in which surface oil dirt and particles are washed; C, annealing; D, painting, evaporating, curing and cooling, in which the step ofD comprises the steps of d1, painting, in which the waterborne insulation paint is coated on a surface of the wire employing a die or felt painting mode; d2, evaporating, in which water in a paintingliquid coated on the wire in the step d1 is evaporated; d3, curing, in which a film formation substance in the insulation paint is crosslinked and cured; d4, cooling, in which the insulation paint film is cooled by a cooling fan; and d5, repeating the steps of d1, d2, d3 and d4 until the paint film is coated on the wire surface for 5-24 times; E, lubricating, in which a lubricating agent is coated on the wire surface after the step D; and F, winding, in which the wire after the step E is taken up. The fabrication method has the advantages that environment protection, energy saving and consumption reduction can be achieved, the fabrication cost of the enameled wire is reduced, and green and circular economic development is achieved.

Description

technical field [0001] The invention relates to the field of manufacturing enameled wires, in particular to a manufacturing process of enameled wires using water-based insulating varnish as an insulating layer. Background technique [0002] Environmental protection and energy saving are two important themes of today's social and economic development. my country is a big producer of enameled wires. With the rapid development of electrical industries such as motors, transformers, and electronic appliances, the demand for enameled wires is increasing day by day. From 50,000 tons in the early 1980s, it has grown to a market size of 2 million tons today. With the increasing output of enameled wire, the resulting environmental problems are becoming more and more serious. At present, the enameled wire enamel is composed of film-forming substances and organic solvents. The film-forming substances are baked and cured to form an insulating paint film. The organic solvents above are al...

Problems solved by technology

[0003] The production of enameled wire will produce organic waste gas and odor. Even if it is collected in an organized way and then burned, it still has odor. If the collection is not good and the combustion is not sufficient, it will cause great harm to the factory boundary and the surrounding environment. This will bring a lot of trouble to the production enterprises, and the price of organic solvents is at least 7,000 yuan / ton, and more than 60% of the solvent in solvent-based insulating paint will be burned by catalytic combustion after evaporation, which will cause a lot of waste

Therefore, the existing enameled wire manufacturing process has the problems of serious environmental pollution, large waste of energy consumption, and high production cost.
