The invention belongs to the technical field of anti-
rust lubricants, and particularly relates to a self-repairing anti-
rust lubricating
aerosol and a preparation method thereof. The anti-
rust lubricant is characterized by comprising an anti-rust
lubricant and a
propellant, the anti-rust
lubricant is prepared from the following
raw material components in percentage by
mass: 18 to 20 percent of
base oil, 5 to 8 percent of an anti-rust agent, 4 to 6 percent of auxiliary lubricating oil, 3 to 5 percent of a penetrating agent, 4 to 6 percent of
dibutyl ether, 1 to 1.5 percent of
petroleum resin, 0.5 to 1 percent of low-molecular-weight
polytetrafluoroethylene micro
powder, 0.5 to 0.8 percent of
graphite, 0.3 to 0.5 percent of
metal bismuth powder, 0.2 to 0.3 percent of
stearic acid, 0.1 to 0.2 percent of
sorbitan monooleate and the balance of water. And the balance of hydrogenated deodorized
kerosene. And the use amount of the
propellant is 40-45% of the total
mass of the antirust lubricant. Through synergistic
raw material combination, the lubricating oil has relatively low
surface tension, is easy to disperse, permeate and spread, and is attached to a friction surface to form a film; through the cooperation of the
graphite, the
metal bismuth powder and the low-molecular-weight
polytetrafluoroethylene micro-powder, the
metal bismuth powder can be fixed on a metal surface and defects or tiny cracks on the metal surface, and
micro defects on a friction interface are dynamically repaired.
