Abstract

The invention discloses a double-layer tear-resistant and refrigerant-resistant enameled aluminum round wire, which comprises a conductor, wherein the outer side of the conductor is provided with a double-layer composite paint film layer, the double-layer composite paint film layer includes variable frequency resistant resin paint and refrigerant-resistant polyamide-imide polyester paint, the outer side of the double-layer composite paint film layer is provided with a polyester-imide paint layer, and the outer layer of the polyester-imide paint layer is provided with a fluorine-containing organic polymer toughening polyamide-imide paint layer. The double-layer tear-resistant and refrigerant-resistant enameled aluminum round wire is provided with the fluorine-containing organic polymer toughening polyamide-imide paint layer, and the added fluorine-containing organic polymer itself has certain lubricity, so that the lubrication effect is good, and the probability of tearing and paint film damage during the winding of enameled wire products is reduced. Meanwhile, the wire is provided with the double-layer composite paint film layer, the utilization of the refrigerant-resistant polyamide-imide polyester paint enables the wire to be good in freezing resistance and solvent resistance, and the wire can be applicable to motor and electrical equipment products in high-temperature, overload and other severe environments.

Description

technical field [0001] The invention belongs to the technical field of enameled wires, and in particular relates to a double-layer tear-resistant and refrigerant-resistant enamelled round aluminum wire. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. With the continuous development of the torque converter, motor, transformer, engine and other manufacturing industries, the continuous change of the application environment and the continuous advancement of science and technology, special enameled wires with high current and voltage resistance are required in more and more occasions. It is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. The quality charac...
