Anti-freezing wear-resistant enameled wire and production process thereof

Abstract

The invention discloses an anti-freezing wear-resistant enameled wire and a production process thereof, which belong to the technical field of enameled wires. The anti-freezing wear-resistant enameled wire comprises a metal conductor and insulating paint coating the surface of the metal conductor, and the insulating paint comprises the following components: a paint base material, a filler, polyanionic cellulose and ethyl p-dimethylaminobenzoate; the insulating paint comprises an inert protective layer, an insulating layer, a wear-resistant insulating layer and a lubricating layer which are coated from inside to outside; the preparation method comprises the following steps of respectively putting corresponding components into different reaction kettles, and stirring while heating until the components are uniformly mixed for later use, preparing a metal conductor, coating preparation, and coating insulating paint: enabling the metal conductor to sequentially pass through different paint grooves to be coated with different paint layers, then carrying out baking, curing and semi-cooling, and finally, carrying out rolling, shaping and complete cooling to obtain the anti-freezing wear-resistant enameled wire. The anti-freezing effect of the enameled wire can be effectively improved, the enameled wire is prevented from being easily cracked at low temperature, and the wear resistance can be improved.

Description

technical field [0001] The invention relates to the technical field of enameled wires, in particular to a frost-resistant and wear-resistant enameled wire and a production process thereof. Background technique [0002] Enameled wire refers to a metal wire that uses insulating varnish as an insulating coating to wind an electromagnetic coil, also known as an electromagnetic wire. It is mainly composed of a conductor and an insulating layer. It has been widely used in industrial appliances, household appliances, telecommunications, In the field of electronic products and other fields, our country has become the world's enameled wire manufacturing center and processing base. It is the world's largest enameled wire production and sales country. The output accounts for about 30% of the global total output, and the annual rate exceeds 10%. In the gradual increase, the market potential is huge. [0003] However, with the development of the times, the quality requirements for ename...

AI Technical Summary

Problems solved by technology

However, there is a lack of corresponding research and corresponding enameled wire products at present.

[0004] Wear resistance is also very important. With daily use, friction or collision, the insulating paint on the surface of the metal conductor will wear and become thinner, and it is also prone to problems such as damage and leakage. It is also related to the tensile strength of the enameled wire. improve

[0005] In addition, in order to meet the smooth performance of the surface of the enameled wire, a lubricating layer is also applied on the surface of the enameled wire. However, the current lubricating layer blindly pursues the lubricating effect, but ignores the scratch resistance and wear resistance. Or it is hung up or damaged when scratched, which is also a headache for the manufacturer.
