Inorganic insulation electromagnetic line and fabrication method thereof

Abstract

The invention discloses an inorganic insulation electromagnetic. After an alloy copper wire is processed in a processing agent, and an insulation layer covers a surface of the alloy copper wire afteremploying a sol deposition mode. Tetraethoxysilane and zinc diricinoleate are mixed and dispersed in an alcohol aqueous solution, alloy after phosphating is added into the mixture, ammonia water is used as a hydrolysis promoter, a layer of insulation sol is formed on a surface of the alloy, and the thermal resistant stability of the sol is further improved by the zinc diricinoleate.

Description

technical field

[0001] The invention belongs to the field of electromagnetic wires, and in particular relates to an inorganic insulated electromagnetic wire and a preparation method thereof. Background technique

[0002] Magnet wire is an insulated wire used to manufacture coils or windings in electrical products. Also known as winding wire, magnet wire must meet a variety of usage and manufacturing process requirements. The former includes its shape, specifications, short-term and long-term work at high temperature, and strong vibration and high-speed centrifugal force in some occasions, corona and breakdown resistance under high voltage, and chemical resistance under special atmosphere. Corrosion, etc., the latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during dipping and drying;

[0003] Magnet wire is an indispensable electrical product in the electrical industry. The motor will generat...
