Nano self-lubricating insulating paint as well as preparation method and application thereof

Abstract

The invention provides nano self-lubricating insulating paint as well as a preparation method and application thereof. The insulating paint is prepared from the following raw materials and the raw materials comprise modified molybdenum disulfide nano powder, a solvent and polyamide-imide insulating paint, wherein the grain size of the modified molybdenum disulfide nano powder is no more than 100nm. The nano self-lubricating insulating paint is applied to preparation of a nano composite self-lubricating electromagnetic wire and the application comprises the following steps: coating the nano self-lubricating insulating paint on the surface of a conductor; baking to obtain a paint film; cooling to obtain a finished product, wherein the conductor is a material obtained by carrying out wiredrawing and coating the insulating paint. When the nano self-lubricating insulating paint is used, the friction coefficient of the paint film is remarkably reduced and reaches about 0.08. A process flow is reduced and the production efficiency is improved; the prepared nano composite self-lubricating electromagnetic wire has a low friction coefficient; the surface quality, adhesiveness, voltage resistance and ageing resistance of the electromagnetic wire are improved; the quality is stable and reliable; the production efficiency and the equipment utilization rate are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic wire insulating varnish, in particular to a nanometer self-lubricating insulating varnish and its preparation method and application, especially to a production process of 200-grade nanocomposite self-lubricating electromagnetic wire. Background technique [0002] At present, there is no production of self-lubricating magnet wire in China, and some enterprises use self-lubricating paint imported from abroad, which is expensive and difficult to promote. Therefore, choose a suitable material with self-lubricating function as an additive to improve the self-lubricating performance of the insulating paint layer of the electromagnetic wire to reduce the surface friction coefficient, and develop an environmentally friendly, energy-saving, safe and effective self-lubricating electromagnetic wire through new technology integration Lacquer is the development trend of the magnet wire industry. The ...
