Abstract
The present invention discloses a kind of lubricant composition, and it includes polyalphaolefin and the thickener for being fatty acid calcium salt.The composition is suitable to use at the seal metal interface in sealed bearings.
Description
Technical field
The present invention relates to a kind of lubricant composition and be related to the lubricant composition be used for sealed bearings in use
On the way.
Background technology
Sealed bearings are used in many different types of machineries.Seal prevents dirt and water from entering, and dirt and water can
Bearing can be destroyed and the function of machinery is damaged.Typical seals material includes acrylonitrile-butadiene rubber (NBR) and fluorine elasticity
Body (FKM).Lubricating grease is provided at seal contact point to extend the life-span of seal.Exist at seal-metal interface
Notable frictional force, this may cause heating and loss in efficiency.Present inventor seeks offer and can be used for reducing seal-metal circle
Frictional force at face and thus improve sealed bearings efficiency lubricant composition.
The content of the invention
Present inventor has unexpectedly discovered that the combination of low viscosity poly alpha olefin base oil and calcium thickener can be provided
The specific lubricating grease for producing low-frictional force at seal-metal interface.Therefore, the present invention provides a kind of lubricant composition,
It includes 40 weight % to 90 weight % first foundation oil ingredients, and it is poly alpha olefin and the dynamic viscosity at 100 DEG C is situated between
In 1mm2/ s to 5mm2Between/s, wherein percentage by weight is based on the weight of lubricant composition；And comprising being C13-C21Fat
The thickener of fat acid calcium salt.
On the other hand, the present invention provides the use that lubricant composition is used at seal-metal interface in sealed bearings
On the way, wherein the lubricant composition includes base oil and thickener, wherein the base oil includes 40 weight % to 90 weights
% first foundations oil is measured, it is poly alpha olefin and dynamic viscosity at 100 DEG C between 1mm2/ s to 5mm2Between/s, wherein
The percentage by weight is based on the weight of lubricant composition；And comprising being C13-C21The thickener of fatty acid calcium salt.
Embodiment
Lubricant composition include 40 weight % to 90 weight % first foundation oil ingredients, its be poly alpha olefin and
Dynamic viscosity at 100 DEG C is between 1mm2/ s to 5mm2Between/s.Lubricant composition can include other base oils, but preferably
Ground, first foundation oil ingredient accounts at least 50 weight %, and the preferably at least 80 total base oils of weight % (press lubricant composition
The gross weight meter of middle base oil).
Thickener in lubricant composition is C13-C21Fatty acid calcium salt, and the castor oil fat preferably hydrogenated
Acid calcium salt.Based on the weight of lubricant composition, the amount of thickener is preferably 2 weight % to 18 weight %, and more preferably 2
Weight % to 14 weight %.
The lubricant composition of the present invention can also be comprising antioxidant, antirust agent, oiliness improver, EP agent, wear-resistant

Lubricant composition can use standard lubricating grease to manufacture approach to manufacture.
The lubricant composition of the present invention is suitable to use at seal-metal interface in sealed bearings.Seal is fitted
Ground is closed by such as acrylonitrile-butadiene rubber (NBR), hydrotreated acrylonitrile-butadiene rubber (HNBR) or fluoroelastomer
Etc. (FKM) material is made.Bearing by containing lubricant and should so that the present invention lubricant composition not by lubricant contamination
Mode come apply the present invention lubricant composition.
Example
The present invention hereafter is further explained in detail by means of example and comparative example, but the present invention is not in any way by these
Example is limited.
By adding base oil and aliphatic acid into kettle, it is heated to 85-90 DEG C (under 3 DEG C/min) and at 100 rpm
Stir to prepare lubricating grease.The calcium hydroxide of powder type is added, water is then added.Closed cauldron and 135 DEG C are heated to (2
DEG C/min under).Content is stirred at 100 rpm and the wall temperature limit of kettle is set as 140 DEG C.After reaching 135 DEG C about
40 minutes, kettle is vented.Extra base oil is heated to 80 DEG C, is then added to by pump in kettle.In being stirred under 150rpm
Tolerant 5 minutes, and product temperatur is held between 130 DEG C to 135 DEG C.Nitrogen tube is connected to kettle, and makes content sudden and violent
It is exposed to nitrogen stream and continues 15 minutes, is thus dehydrated sample.Under stirring at 100 rpm, content is set to be cooled to 100 DEG C (2
DEG C/min under).Additive is added under 80 DEG C or lower temperature, the additive is diluted using extra base oil.Adding
After doping, content is stirred at 100 rpm 1 minute.Then make content be cooled to 50-60 DEG C (to set by wall temperature
To control：20 DEG C and stirring at 100 rpm under 5 DEG C/min).At 70 DEG C, kept for 10 minutes using -150 millibars of vacuum
And stirred with 50rpm, start degassing.Product homogenizes under 1 × 300 bar.
Whole composites are all summarized in table 1 below, and amount is provided by the gross weight meter of composite with weight percents.
Table 1
PAO 2.0 is poly alpha olefin and the viscosity at 100 DEG C is 2.0cSt.XHVI 3.0 and XHVI 4.0 is to pass through
Fei Sheer-Top wishes the base oil of method (Fischer-Tropsch process) preparation and obtained from shell (Shell).
Viscosity of the XHVI 3.0 at 100 DEG C is that the viscosity of 3.0cSt and XHVI 4.0 at 100 DEG C is 4.0cSt.HCOFA is hydrogen
Change Castor Oil Fatty Acid.In each example and comparative example, additive bag is identical.
Lubricating grease is applied to NBR seals.Sealed bearings are run 24 hours, then measure frictional force.
As a result it is given in Table 2：
Table 2
| Frictional force levels (Ncm) | |
| Example 1 | 1.88 |
| Comparative example 1 | 3.06 |
| Comparative example 2 | 3.12 |
The lubricant composition (wherein base oil is poly alpha olefin) of the present invention and the lubricant composition of comparative example are (wherein
Base oil, which has similar viscosity but wishes method by Fei Sheer-Top, to be made) compared to illustrating significantly reduced frictional force.
