Embodiment Construction

[0010] Firstly prepare the molybdenum disulfide liquid lubricant for electric use: (1) Modification of epoxy-amine resin: the purpose of modification is to increase the charged ions on the rubber chain, so that the resin becomes a water-soluble conductor, and the modification of the resin Another purpose is to be able to link the curing agent. Add amine to the epoxy resin for ring-opening treatment to form a water-soluble resin, and then add polyamide resin to link it to increase its molecular weight, and finally achieve that the resin is both conductive and water-soluble, and has the ability to wrap molybdenum disulfide carrier , forming an epoxy-amine modified resin. (2) Take 2kg of epoxy-amine modified resin, 1kg of molybdenum disulfide, 0.2kg of ethylene glycol butyl ether (additive), 0.8kg of acetic acid (cosolvent) and 1kg of deionized water, mix, grind and mix well, Stirring and aging at 26-30°C for more than 24 hours to obtain the stock solution of molybdenum disulfid...

Abstract

The invention discloses a method for electrodeposition of a solid lubricating film by a molybdenum disulfide liquid lubricant. The method consists of: first cleaning a part, putting the part in a molybdenum disulfide liquid lubricant, conducting electrodeposition for 1-5min under a voltage of 50-90V and a temperature of 26-30DEG C, then taking the part out, cleaning and draining it, and curing the part for 20-40min at 170-180DEG C, thus obtaining a molybdenum disulfide solid lubricating film formed on the part. Compared with current methods that always rely on the traditional mode of spraying a solid lubricating film to satisfy lubrication performance need, the method provided in the invention makes the lubricating film with good uniformity and binding force. The film can be assembled and disassembled repeatedly without being damaged, can work under high and low temperature environments, has the property of special medium (red oil) resistance, and guarantees the lubrication property, resistance to corrosion, seizure and the like of the lubricating part, thus being able to be applied to lubrication of various high precision bearings in the fields of aviation, aerospace, and ships etc., and also being applicable to solid lubrication of parts in other fields.

Description

technical field [0001] The invention relates to the technical field of solid film lubrication, in particular to a method for electrifying a solid lubricating film with a molybdenum disulfide liquid lubricant. Background technique [0002] The solid film lubrication technology was developed only after the Second World War. The United States, the former Soviet Union and other countries applied the lubrication technology to the fields of aero-engines, aircraft, space satellites, missiles, and spaceships, and it has been well applied and recognized. promote. However, the research on solid film lubrication technology in my country began in the late 1950s, and in the early 1960s, solid lubricating materials have achieved satisfactory application results in some national defense and military industrial units. In the aspect of solid lubricating materials in our country, there has been great development in the past forty years. Relevant research work is very active, and has solved ...
