The enameled wire is an important electrical insulating part, an enameled wire paint film coated on the enameled wire is used for enabling a good insulating layer to be generated between a lead wire and a lead wire in a winding so as to maintain the normal operation of the whole workpiece equipment, and the enameled wire paint is an indispensable electric insulating coating applied to the electrical equipment and is one of key raw materials for controlling the economy, the technology, the index and the operation life of the electrical equipment, so that the enameled wire paint needs to have better heat, electricity, mechanical and chemical resistance;

at present, all fine enameled wires are made of copper, the coil weight is reduced as much as possible in application scenes needing light weight, so that the product performance is improved, although copper is metal with the highest electric conductivity, the density is high, the coil weight is not light, the performance of an application product is influenced, the heat resistance of the existing fine enameled wires is poor, and the normal use of the fine enameled wires is influenced when the existing fine enameled wires are used in a high-temperature environment;

How to make a micro enameled aluminum wire?
step C1: carrying out wire drawing treatment on the aluminum wire;
step C2: annealing and cooling the drawn aluminum wire at the temperature of 400-500 ℃;
step C3: and spraying paint on the annealed aluminum wire by using micro paint, and curing a paint film to obtain the micro enameled aluminum wire.
Further, the micro paint comprises the following raw materials in parts by weight:
10-15 parts of potassium silicate, 8-10 parts of high-temperature resistant filler, 60-80 parts of deionized water, 0.001-0.003 part of melamine, 5-8 parts of glass powder, 8-10 parts of barium titanate, 8-10 parts of talcum powder, 30-40 parts of styrene-acrylic emulsion and 10-15 parts of propylene glycol butyl ether;
