Abstract

The invention discloses a thin-film anti-corrosion electromagnetic wire. After the alloy copper wire is treated in a thin-film anti-corrosion solution, the surface of the alloy copper wire is covered with an insulating layer by means of sol deposition. The thin-film anti-corrosion solution of the present invention uses alcohol ester Twelve is a film-forming aid, blended with phosphate, silicate, and sulfate, which can effectively improve the rust and corrosion resistance of the alloy, and the added calcium acetylacetonate is blended with stearic acid to form a film The method is coated on the surface of the alloy, which has a good effect of heat resistance and anticorrosion; the present invention uses aluminum isopropoxide as a precursor, hydrolyzes in an alkaline solution, deposits it on the surface of the alloy, and then sinters to realize the sol The coated alloy electromagnetic wire has a very good protection effect on the alloy.

Description

technical field [0001] The invention belongs to the field of electromagnetic wires, and in particular relates to a thin-film anti-corrosion 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. However, the current commercially available magnet wires have poor anti-corrosion performance, and are pro...
