Embodiment 1

[0039] Embodiment one: see figure 1 with image 3 Figure (a).

[0040] Chemical base film treatment is carried out on the ring surface of the steel ring whose material 1 is 40Cr to form a phosphating layer 2 with a thickness of 6 to 10 μm, and then form 3 to 3 by rubbing one or several solid lubricants on the surface of the first transition layer. 5 μm thick second transition layer 3 . A polyester powder coating type solid lubricating film 4 with a thickness of 20-50 μm is coated on the annulus by means of electrostatic spraying and high-temperature curing. The curing conditions are: 180~220°C, 10~30min. In terms of mass percentage in the coating, the polyester resin CC440 is 30-85%, the curing agent TGIC is 3-40%, and the 3,5-di-tert-butyl-4-hydroxyphenyl octadecyl propionate is 3-5%. %, silicone leveling agent is 0.5-5%, benzoin is 0.2-1%, titanium dioxide and wollastonite are 3-25%, solid lubricant is molybdenum disulfide 3-20%, boron nitride 0-15% %, barium borate 0-1...

Abstract

A powder paint type lubricating solid membrane is prepared through cleaning the surface of metallic basic body, preparing priming member by chemical reaction, coating solid lubricant to form a transition layer, and spraying high-molecular powder layer. A gear with said lubricating solid membrane is also disclosed.

Description

technical field [0001] The invention belongs to the technical field of lubrication, in particular to a powder coating type solid lubricating film and a preparation method thereof. Background technique [0002] Dry film lubrication is a technique in which solid lubricants, wear-resistant additives, etc. are firmly bonded to the moving friction surface by means of a binder to play a protective role in wear-resistant lubrication. The material forming a solid lubricating dry film is called a dry film lubricant. The dry film formed by the dry film lubricant can act as a solid lubricating film under dry friction conditions, and can also be used together with lubricating oil, grease, and paste, as well as an anti-corrosion protective film. It is also used for repairing or The surface is anti-adhesive and anti-fouling (dirt), etc. It has been widely used in friction parts and parts requiring proper protection in aerospace, aviation, machinery, transportation, electronics, construc...
