The saturated hydrocarbon content of the deep refining base oil is 90-99wt%, and sulfur content is 0.001-0.01wt%, viscosity
Index IV >=140.
The nano metal protective agent is close power iron (Militec-1).
The phenolic antioxidant is antioxidant 264, antioxidant 1010, antioxidant 330, antioxidant 1076, antioxidant CA, anti-
One or more in oxygen agent 2246.
The tackifier are polybutene, polyisobutene, polymethacrylates, one or more in ethylene-propylene copolymer.
The antiwear additive is 3- neighbour's isopropoxy carbonyl phenyl boric acids, chlorinated paraffin, sulfide isobutene, tricresol phosphate
One or more in ester, di-n-butyl phosphite, triphenyl phosphate, lead naphthenate.
The antirust agent is BTA, barium mahogany sulfonate, lanolin magnesium soap, natrium nitrosum, dialkyl dithio phosphorus
One or more in sour zinc.
A kind of preparation method of above-mentioned lubricant grease for brake system of car, is characterized in that：Carry out according to the following steps：
(1) by deep refining base oil, stearic acid, aerosil input saponification kettle, pressure 0.1MPa, heating rise
Temperature is sufficiently stirred for 30min to 100-120 DEG C；
(2) aluminium hydroxide is put in saponification kettle, pressure 0.1MPa, temperature 100-120 DEG C are sufficiently stirred for 30min, carry out
Saponification；
(3) be heated to 180-200 DEG C carry out the compound refining 30min of high temperature after, kettle cover addition is opened when being cooled to 100 DEG C
Phenolic antioxidant, tackifier, antiwear additive, antirust agent and nano metal protective agent, are stirred 30-40min；
(4) after in kettle, raw material cools, homogeneous, degassing, filter after obtain finished product.
Preferably, in step (4), filtration treatment is using 120 mesh filter screen filtrations.
It is after using above-mentioned technical proposal, of the invention compared with existing background technology, have the advantage that：
The lubricant grease of the present invention has excellent resistance to elevated temperatures and antiseptic property, while having good extreme-pressure anti-wear
Property, excellent cryogenic property, dropping point be high, and adhesiveness is good, and loss is few, noncoking.Specialty solves the wheel cylinder of brakes clamp and leads
To the problem of the insufficient lubrication at the positions such as pin, dirt-proof boot, the purposes such as protection dirt-proof boot, lubrication wheel cylinder guide finger are played, system is improved
The sensitivity of dynamic system, shortens braking distance, greatly promotes braking safety, extends dirt-proof boot service life, it can also be used to its
During his type device requires higher bearing lubrication.
