Description
Technical field
The invention belongs to technical field of lubricating grease, more particularly to a kind of passenger car hub bearing lubricating grease composition and system
Preparation Method.
Background technique
Automotive lubricating reases product mainly includes automotive hub and chassis grease versatile, that dosage is big, Yi Jiyong
Lubricating grease in positions such as CVJ, door lock, vehicle window, engine environment sealing bearings.The automobile sales volume in China increases year by year, automobile
Manufacture level there has also been development at full speed, automobile bearing increasingly develops to high speed, high reliability and long-life direction, wants simultaneously
Ask the lubricating grease for components such as hub bearings that there is high temperature resistance, extreme pressure and antiwear behavior, water-resistance, colloid stability, prevent
Rust property, shear stability etc., the product used originally has been unable to meet the needs of performance, and some Super Quality Lubricant Grease products are such as multiple
Close lithium, polyureas etc. more and more attention has been paid to.So some full-sized car bearings producer of the country is to shell, Mobil, collaboration etc. at present
The products such as complex lithium, the polyureas of offshore company are more favored, but due to the factors such as its price is higher, so that producer is to corresponding domestic
The cry of rouge demand is higher and higher.For the exploitation for realizing independent brand profession lubricating grease, China is pushed further into superior automobile
The exploitation of automotive lubricating reases is included in emphasis tackling key problem item by the production technology of wheel hub lubricating grease and the development in application technology, my company
Mesh.
Automotive hub has the following characteristics that under different road conditions, hub bearing bears irregular punching in the process of running
Itself car weight and load-carrying are still suffered from while hitting load；Because the chance that close from the ground and water contacts is relatively more；Hub bearing
Centrifugal force it is larger, the case where getting rid of rouge, happens occasionally；Automobile lie substantially in outdoor state, by seasonal weather variation influenced compared with
Greatly.
The lubricating grease used on vehicle is mostly soap base grease, such as calcium-base grease, lithium base grease, aluminium-base grease
And complex lithium grease etc..At present the existing automobile-used fat prod of company extreme pressure anti-wear, water-resistance, heat-resisting quantity etc. cannot
Meet the requirement of riding vehicle hub bearing, therefore there is an urgent need to develop the lubricating grease for being suitable for passenger car.
This exploitation passenger car hub bearing lubricating grease, mainly for riding vehicle hub bearing demand exploitation product,
Product has good high temperature resistance, extreme pressure and antiwear behavior, water-resistance, colloid stability, rust-preventing characteristic, shear stability etc.,
Sexual valence is relatively high, meets the use needs of riding vehicle hub bearing.
Summary of the invention
Of the invention there is service performance difference for passenger car hub bearing lubricating grease and lead to insufficient lubrication, such as high-temperature stream
The problems such as mistake, shear shinning, propose a kind of lubricant composition and preparation method thereof for passenger car hub bearing, the lubrication
Rouge has high temperature resistance outstanding, extreme pressure and antiwear behavior, water-resistance, colloid stability, rust-preventing characteristic, shear stability etc..
Technology of the invention is as follows:
A kind of passenger car hub bearing lubricating grease composition, it is characterised in that based on the overall weight percent of composition, packet
Include following components:
Base oil 85~90%；
Thickening agent 10~15%；
By above-mentioned two components total amount, following additive mass percent is added:
Antioxidant 1~2%；
Antirust agent 0.05~0.1%；
Extreme pressure anti-wear additives 1~2.5%.
Wherein, thickening agent is the fatty acid salt of the reactant aqueous solution generation of fatty acid and alkali.Fatty acid is 12- in thickening agent
The mixture (4:1~6:1) of hydroxy stearic acid and decanedioic acid；Alkali is the mixed aqueous solution of lithium hydroxide and calcium hydroxide, hydrogen-oxygen
The mass ratio for changing lithium and calcium hydroxide is 5:1~7:1.
The base oil is the mixture of mineral oil, it is desirable that 40 DEG C of range of viscosities of base oil are in 80~140mm2/s。
The antioxidant be 0.5%~1% phenolic antioxidant and 0.5%~1% amine antioxidants collective effect, preferably
Antioxidant is Liquid polymeric phenolic antioxidant (Tianjin Li Anlong) and di-iso-octyldiphenylamine (Shanghai Yu Cheng).
The antirust agent is benzotriazole.
The extreme pressure anti-wear additives are 0.5%~1% sulfide isobutene and 0.5%~1.5% trithiophenyl phosphate.
Reaction kettle is added in 30%~40% base oil by the preparation method of passenger car hub bearing lubricating grease of the invention
In, 12- hydroxy fatty acid and decanedioic acid are put into, heating melts it completely, then 40%~50% base oil is added in kettle
So that temperature is down to 80~85 DEG C, the mixed aqueous solution of 1:5 made of 50% lithium hydroxide and whole calcium hydroxides, heating is added
Start to be saponified to 85~92 DEG C；Saponification terminates heating, and temperature of charge rises to 100~110 DEG C, and the 1:5 of remaining lithium hydroxide is added dropwise
Aqueous solution starts to warm up draining after completion of dropwise addition, temperature of charge rises to 195~200 DEG C of maximum temperature after draining, constant temperature 5
~8 minutes；Remaining base oil is added, temperature in the kettle is made to drop to 160~170 DEG C, antioxidant, stirring is added；Continue to cool down, drop
It is stirred to 80 DEG C or less addition antirust agent, extreme pressure agent；Then ground and degassing postprocessing working procedures obtain finished product lubricating grease.
Lubricating grease of the invention has an advantage that complex lithium thickening agent makes the water repelling property and shearing property of the lubricating grease
Can be prominent, the performances such as work cone penetration can and can be extended from anti-water drenching and embodied；Suitable base oil type and proportion, assigns
Lubricating grease excellent low temperature and viscosity temperature characteristic can be good at meeting temperature range of the passenger car hub bearing at -30~150 DEG C
Interior requirement；The reasonable process conditions for being formulated and being suitable for obtain uniform soap fiber structure, effectively raise profit
The colloidal stability of consistent lubricant, the lubricating grease of preparation not only have water-resistance outstanding, inoxidizability, also have and divide oil cut rate low, resistance to
The features such as high-temperature behavior is good, shear stability is high, high temperature performance and anti-corrosion protection effect are good can preferably meet riding wheel
The requirement that hub axle is held, the use temperature range of the lubricating grease are -30~150 DEG C.
According to the actual use operating condition of passenger car hub bearing, the extreme pressure anti-wear (P of product is paid close attention toDValue), water-resistance it is (anti-
Aqueous, water drenches number of dropouts), colloid stability (Stencil oil-dividing), rust-preventing characteristic (anticorrosive property), shear stability (extend Drawing cone
The difference of in-degree and work cone penetration) etc., by the performance of product of the invention such as the following table 1:
The typical index of 1 this product of table
