Embodiment Construction

[0026] The metal anti-friction and anti-friction dynamic self-repairing lubricant of the present invention is a composition of mineral matter, suspending agent and lubricating oil, and is characterized in that the proportioning of the lubricant is by weight percentage:

[0027] Mineral powder composition 0.005-5.0: suspending agent 2.5-4.0: lubricating oil 92-97.50%;

[0028] The proportioning of the mineral powder composition is by weight percentage:

[0029] Chrysotile 57.50-64 blue asbestos 12-16 actinolite 4.5-6 aphanitic graphite 9-12 diopside 4.5-6 sericite 4.5-6.

[0030] The proportioning of the suspending agent composition is: the weight percentage is 25% polyoxyethylene ester C 17 C 35 COO(C 2 h 4O ) 6 H and heptadecylammonium ethyl ammonium ethyl imidazoline with a weight percentage of 75% are resistant to high temperature, do not change color when heated to 200° C., and do not produce bubbles.

Abstract

The metal friction resisting and wear reducing dynamically self-repairing lubricant is composition of mineral matter, suspending agent and lubricating oil; and features that the mineral matter consists of chrysotile 57.5-64 wt%, blue asbestos 12-16 wt%, amorphous graphite 9-12 wt%, diopside 4.5-6 wt% and sericite 4.5-6 wt%. The preparation process of the metal friction resisting and wear reducing dynamically self-repairing lubricant includes the following steps: processing the mineral matter into 2-5 micron powder and mixing to form combined mineral powder; mixing the combined mineral powder with suspending agent and lubricating oil through heating and stirring; and packing. Test shows that the lubricant can form protecting layer on the friction pair surface with hardness over 2 times of iron-base alloy, and result in friction coefficient one magnitude order lowered.

Description

technical field [0001] The invention relates to a lubricating composition, a solid lubricant with dynamic self-repairing function and a preparation process. Background technique [0002] Solid lubricant refers to the use of solid powder, film or some overall material to reduce the friction and wear between two relatively moving bearing surfaces. At present, there are many substances suitable as solid lubricants, which can be roughly divided into the following categories: [0003] 1. Layered structure substances: mainly graphite, graphite fluoride, mica, molybdenum disulfide, boron nitride, etc. [0004] 2. Soft metals: mainly lead, tin, indium, zinc, silver, gold, etc. [0005] 3. Polymer materials: mainly nylon, polyethylene, polytetrafluoroethylene, polyimide, etc. There are also some oxides, fluorides and organics. [0006] Their common mechanism of action is to form a film-like substance on the surface of the two friction pairs, thereby reducing the friction and wear...
