Description
Technical field
The present invention relates to OIL IN LUBRICATING OIL PRODUCTION technical fields, and in particular to a kind of environmental and durable lubricating oil of multifunctional low-temperature.
Background technique
It is right for applying the demand for lubricating oil between each components constantly to expand with the rapid development of mechanical industry
It is also higher and higher in the performance requirement of lubricating oil, and people for lubricating oil environmental protection, in terms of also pay attention to day by day.
The lubricant of plant oil base is a kind of environmentally friendly lubricating oil, such as soya-bean oil, rapeseed oil, cottonseed oil, corn oil
Deng the biodegradable of this lubricant is the main performance indicator of its ecological effect, at present the lubricant of plant oil base
There is a problem of oxidation stability, hydrolytic stability and low temperature flow deficiency, in consideration of it, it is more to provide one kind regarding to the issue above
The durable lubricating oil of function low-temperature environment-friendly.
Summary of the invention
The purpose of the present invention is to provide a kind of environmental and durable lubricating oil of multifunctional low-temperature, and the lubricating oil is pollution-free, green
Environmental protection, easy degradation, oxidation stability is good, hydrolytic stability is good, low temperature fluidity is prominent and excellent rustless property.
To achieve the goals above, the invention provides the following technical scheme:
A kind of environmental and durable lubricating oil of multifunctional low-temperature, which is characterized in that be made by the raw material of following parts by weight: plant
Basic synthetic oil 80-130 parts, 1-3.5 parts of VI improver, 2-4 parts of antioxidant, 1-3 parts of defoaming agent and water 120-150
Part.
Preferably, plant basis synthetic oil is made by the raw material of following parts by weight: 10-30 parts of soybean oil, vegetable seed
85-100 parts oily, 5-15 parts of linseed oil, 7-15 parts of the concentrated sulfuric acid and 10-15 parts of triethylene glycol.
Plant basis of the present invention synthetic oil is by soybean oil, rapeseed oil, linseed oil, the concentrated sulfuric acid and triethylene glycol group
At, wherein soybean oil, rapeseed oil and linseed oil are natural biomass oil, and natural biomass oil can freely degrade, it is pollution-free, it is green
Colour circle is protected.
Preferably, the plant basis synthetic oil following steps processing preparation:
S1: the soybean oil, rapeseed oil and linseed oil of corresponding parts by weight being added in blender and dispersed, and control revolving speed
1500-1700r/min stirs 15-20min, obtains component A；
S2: component A is heated to 65-75 DEG C, triethylene glycol is added, revolving speed 1700-2000r/min is controlled, continues to stir
35-40min obtains component B；
S3: being added the concentrated sulfuric acid in component B by several times and be acidified, and tests solution ph after being added every time, obtains component C；
S4: component C is filtered, drying and processing obtains solid plant basis synthetic oil.
In plant basis synthetic oil synthetic method of the present invention, using the catalyst concentrated sulfuric acid using its highly acid and by force
Protonation ability promotes the formation of acyl cation, and esterification is made to carry out and reduce the back reaction of ester hydrolysis to positive reaction；Together
When, the concentrated sulfuric acid is added by several times and is acidified, tests solution ph after being added every time, when solution ph is 7-8, stops being added dense
Sulfuric acid can promote plant basis synthetic oil to hydrolyze, and plant basis synthetic oil is in neutral medium because solution acidic is larger
Hydrolysis speed is lower than the hydrolysis speed in acid medium, it is therefore desirable to control the pH value of solution；In addition, passing through
The concentrated sulfuric acid is removed after filter drying and processing, obtains the good plant basis synthetic oil of hydrolytic stability.
Preferably, the VI improver is by following steps processing preparation:
By graphene oxide: VI improver: dehydrated alcohol is with (0.2~0.6): blender is added in the ratio of 5:30
Middle dispersion obtains uniform mixed liquor, and granulation is dried using spray-dried instrument to mixed liquor, and it is 50 micro- that average grain diameter, which is made,
The VI improver of rice, the VI improver are polymethyl methacrylate.
VI improver preparation method of the present invention uses dehydrated alcohol as solvent, graphene oxide because
Hydroxyl, epoxy group are contained in its surface, and there is carboxyl at edge, and these oxygen-containing groups can provide for the VI improver of connection
A large amount of active site keeps VI improver attached thereto, and a portion graphene oxide can wrap up viscous
Index modifier is spent, preferable package action formation specified particle diameter can be played to VI improver has slow releasing function
VI improver, can not only guarantee early period have wettability, can also change in later period slow release viscosity index (VI)
Property agent, using graphene oxide can guarantee its wrap up better effect, guarantee the VI improver later period also have it is certain
Greasy property and excellent surface-active make the lubricating oil later period also have excellent greasy property and low temperature stream under cryogenic
Dynamic performance；Wherein another part graphene oxide is reunited because not being completely dispersed, after mixing in lubricating oil, this partial oxidation stone
Black alkene is because itself having the oxygen-containing group of the reference area of super large and surface that can associate with water molecules hydrogen bond, on plant basis
It synthesizes oil meter face and forms the film of one layer of exclusion of water, thus prevent plant basis synthetic oil from contacting with moisture, moisture and acidic materials,
To play anti-rust action.
Preferably, the antioxidant is β-(3,5- tert-butyl -4-m hydroxy phenyl the third) sour octadecanol ester, described to disappear
Infusion is silicone oil class defoaming agent.
The antioxidant that the present invention uses can be improved oil ageing stability, effectively prevent metal oxidation, delays
Oil ageing speed, and it is nontoxic and pollution-free, it is environmentally protective.
The defoaming agent that the present invention uses has excellent hydrophily and expandability, under the high temperature conditions, heats and repeatedly follows
Ring heating, on defoaming activity without influence, keeps the lubricating oil scope of application wider, and better effect is stablized.
Preferably, the environmental and durable lubricating oil of the multifunctional low-temperature the preparation method comprises the following steps:
Corresponding parts by weight water is first added in blender, revolving speed 2000-2200r/min is controlled, is heated to 40-50 DEG C,
The dispersion of solid plant basis synthetic oil is added, continues that antioxidant and the defoaming of corresponding parts by weight is added after stirring 40-50min
Agent controls revolving speed 2500-3000r/min, and revolving speed is reduced after stirring 10-15 minutes to 1000-1200r/min, corresponding weight is added
The VI improver of number is measured to get the environmental and durable lubricating oil of multifunctional low-temperature is arrived.
The beneficial effects of the present invention are:
(1) the environmental and durable lubricating oil of a kind of multifunctional low-temperature of the invention is by biodegradable base oil and a variety of auxiliary agents
It configures, can be biodegradable in a short time, pollution-free, environmentally protective；
(2) by the present invention in that being modified with the graphene oxide of special ratios to VI improver, because of oxidation
Graphene surface contains hydroxyl, epoxy group, and there is carboxyl at edge, and these oxygen-containing groups can be the VI improver of connection
A large amount of active site is provided, keeps VI improver attached thereto, a portion can wrap up viscosity index (VI)
Modifying agent can play the viscosity with slow releasing function that preferable package action forms specified particle diameter to VI improver
Index modifier can not only guarantee that early period has wettability, can also make in later period slow release VI improver
It can guarantee that it wraps up better effect with graphene oxide, guarantee that the VI improver later period also has certain greasy property
And excellent surface-active, make the lubricating oil later period that also there is excellent greasy property and low temperature fluidity under cryogenic；
