Abstract

An insulating heat-resistant enameled wire coating, the enameled wire coating comprises an inner coating coated on the surface of the enameled wire, an intermediate coating located on the inner coating and an outer coating coated on the intermediate coating . By coating the inner coating, intermediate coating and outer coating on the outer surface of the enameled wire, the enameled wire has better insulation and heat resistance performance, and the coating will not be aged or damaged due to heat during use, and short circuit can be avoided. Accident; the enameled wire coated with this coating is especially suitable for high-speed rotating motors, and can keep the rotor running stably for a long time; at the same time, the raw material cost of the coating is low, and it is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of enameled wires, in particular to an insulating heat-resistant enameled wire coating. 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. However, 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. Therefore, the quality characteristics of various enameled wires are different, and their mechanical properties , chemical properties, electrical properties, and thermal properties need to be further improved. Contents of the invention [0003] In order to solve the above problems, the present invention provides an enameled wire coating with good mechanical properties, stable chemical p...
