Description
Technical field
The present invention relates to lubricant oil composite and preparation method thereof more particularly to a kind of electric compressor lubricating oil compositions
Object and preparation method thereof.
Background technique
With the rapid development of the automotive industry, city environmental pollution is on the rise, both at home and abroad all greatly develop cleaning,
Energy-efficient electric vehicle, and electrodrive air compressor is the necessary equipment of all gas braking electric cars.Especially new energy visitor
The application of the continuous development of vehicle, electric air compressor is also more and more common.Existing electric air compression set is from lubricating system
Can be divided into has oil lubrication and two kinds of oil-free lubrication, and wherein the electric compressor of oil-free lubrication does not pass through profit due to components
The protection of lubricating oil and directly contact, cause compressor structural components abrasion very fast, the service life is short, and because the sealing of lubricating oil is made
With compression efficiency is relatively low.There is the equipment that oily electric compressor is relatively high as working efficiency in air compressor machine, in integral new-energy passenger
In application than wide.
The electric compressor for having oil lubrication mainly includes rotary vane type, screw and piston type.They all suffer from same ask
Topic, i.e., in air compression process, dehydration in air and as mechanism operating enters in lubricating oil causes lubrication cream
Change, especially emulsification of lubricant is more serious when summer, air humidity was bigger, eventually leads to air compressor maintenance period
It shortens, increases maintenance cost.It is therefore desirable to which oil product has good resistance to emulsion, but traditional engine lubricating oil meets water electrode
Easily emulsification, this will lead to oil property sharp fall, is unable to satisfy requirement.In addition, according to producer to electric compressor
From the point of view of the requirement of maintenance period, replacement cycle of oil product need to up to 90000 kilometers or 12 months, and the kinetic temperature of air compressor machine compared with
Height, this requires oil products to have excellent inoxidizability and detergency, avoids the generation of oil product premature oxidation and carbon deposit, leads to oil
Filter blocking or air compressor machine high temperature stopping accident, the acidic materials for aoxidizing generation can also cause to corrode to air compressor machine component, practical
The replacement cycle of upper oil product can not reach requirement.For slide sheet type electric compressor, lubrication in compression process and
Cooling is completed by an efficient injection system, which can guarantee to complete in the case where lower lubrication oil consumption is horizontal
Process control, the oil film that system is formed in rotor inner wall can avoid the contact of metal parts, abrasion be eliminated, it is therefore desirable to lubricate
Oil has preferable wear resistence.
Current published related patents are both for traditional stationary air compressor oil, and the drain period is relatively
It is short, and there are oil acids to become faster, be easy discoloration and high temperature generates the problems such as precipitating.It is electronic compared with conventional fixed-type air compressor machine
The features such as air compressor machine has small in size, and gas production is big, high-efficient, and vehicle mounted electric air compressor machine due to vehicle road conditions it is badly multiple
Miscellaneous, the working environment that will lead to air compressor machine is harsher, and lubricating oil is easily contaminated, also more to the performance requirement of lubricating oil
It is harsh.
Summary of the invention

Lubricant oil composite made from Examples 1 to 4 and comparative example 1 is subjected to performance detection, test result is shown in Table 1.
The performance detection data of each embodiment lubricant oil composite of table 1
The test result of Examples 1 to 4 can be seen that oil product through a long time high-temperature circulation test of the invention from table 1
Afterwards, 40 DEG C of kinematic viscosity change rates are less than 3.2%, and acid value change rate is less than 27%, and oil product changes colour small, oil after high-temperature baking
Product very slight color (amber or rufous), residue seldom (are less than 0.075g), illustrate that oil product has excellent high-temperature oxidation resistant
Property and antiacid value changing capability.When the not anti-acid inhibitor of oil-containing in comparative example 1, after through a long time high-temperature circulation test, 40
DEG C kinematic viscosity change rate 8.13%, acid value change rate is up to 73.45%, and oil product changes colour greatly after high-temperature baking, becomes rapidly
For black, level of residue is also relatively large (0.193g).Therefore, when lacking anti-acid inhibitor in lubricant oil composite, exist
The problems such as oil acid becomes faster, and is easy discoloration and high temperature production precipitating.
The compressor oil resistance to emulsion of general conventionally employed Esters oil allotment is in 20min or more, and product of the invention
Resistance to emulsion is in 10min hereinafter, showing preferable resistance to emulsion.
Compare the extreme pressure property P of comparative example 1 and Examples 1 to 4 oil productBValue and emulsion resistance time are it is found that oil soluble polyether
Addition can not only improve the inoxidizability and antiacid denaturation of oil product, can also be with suitable extreme pressure anti-wear additives and demulsifier
Rationally compounding, plays the coordinative role between each additive, greatly improves the abrasion resistance and resistance to emulsification of oil product.
Comparative example 2
This comparative example is substantially the same manner as Example 1, and it is 5% that difference, which is only that the additional amount of anti-acid inhibitor is different,.
Comparative example 3
This comparative example is substantially the same manner as Example 1, and difference is only that the additional amount of anti-acid inhibitor is different, is
20%.
The performance detection data of lubricant oil composite made from 2 embodiment 1 of table and comparative example 2~3
It can be seen that by table 2, the additional amount of anti-acid inhibitor is very few in comparative example 2, to the rejection ability of acid value variation
Poor, oil product changes colour greatly after high-temperature baking, rapidly goes to black；And the additional amount of anti-acid inhibitor is excessive in comparative example 3,
Although oil product shows excellent antiacid denaturation, oil product volatility increases, and leading to oil product, loss amount is larger at high temperature, waste
Seriously, use cost is considerably increased, kinetic temperature when air compressor machine works normally is very high, so that oil product is unable to satisfy height
Warm requirement.Therefore the additional amount of anti-acid inhibitor is 10%~15% in the present invention.
It can be seen that electric compressor of the invention oil has an excellent high-temperature oxidation resistance, extreme pressure anti-wear and anti-
Emulsibility, and oil product is of light color after high temperature oxidation for a long time, deposit is few, and acid value and viscosity change are smaller, can be electronic pneumatics
Machine provides long-acting lubrication protection, and can help to reduce the operating temperature of air compressor, substantially increases air compressor fortune
Capable safety and stability, and the drain period is up to 8000h or more.
