Description
Technical field
The invention belongs to lube oil additive technical field, and in particular to antifriction antiwear type lubricating oil additive and its preparation
Method.
Background technology
Friction is a kind of inevitable natural phenomena, annual to be accounted for for reducing the fuel that machine components fretting wear is used
Total rate of fuel consumption amount 1/3, in addition, friction can also cause the unhelpful loss of mechanical energy, shortens service life of a machine, reduction machinery effect
Rate.In order to solve the above problems, searching can reduce friction, and the material for reducing abrasion is particularly important, therefore is commonly incorporated into profit
Lubricating oil, and in order to improve the tribological property of lubricating oil, appropriate additive is often added into lubricating oil.Lube oil additive
Refer to by a certain percentage and blending technology is mixed and can met the mixing of the single dose or several single doses of certain mass class requirement
Thing.
With the progress and development of society, concern of the mankind to environmental protection is increasingly strengthened, environment-friendly lubriation material
Research is imperative.Environmental friendly lubricant fat material refers to that the duty requirements of plant equipment can be met have again well
Biodegradability, does not produce the lubricant grease material of harm to ecological environment.Plant oil base lubriation material is distinctive due to its
High biological degradability, low eco-toxicity and recyclability, cause the attention of lubrication scientific worker.At present, to vegetable oil
The research of base lubriation material is concentrated mainly on two aspects.One is to improve it by the method for chemical modification or bio-modification to aoxidize
Stability, hydrolytic stability, improve cryogenic property, become the base oil of excellent performance；Two be the side by chemical modification
Method induces one the active function groups with greasy property in vegetable oil molecule, carries out grinding for vegetable oil base envionmentally friendly lubricating additive
Study carefully.Vegetable oil chemical modification method mainly includes selective oxidation, dimerization/oligomerization reaction, straight chain, epoxidation, esterification and ester
Exchange etc.；Bio-modification is then the gene for changing crop using modern biotechnology, and vegetable fatty acids composition is regulated and controled,
To change the effect that its chemical constitution reaches its physicochemical property of improvement.Oily lubriation material extensively should based on vegetable oil
For fields such as outboard two stroke engine oil, chain saw oil, rail oil, hydraulic oil, lubricating grease and metal working fluids.At present, plant
Thing oil base additive mainly has vulcanized vegetable oil, mercaptan addition vegetable oil, boron nitridation vegetable oil, boronation vegetable oil etc..It is overall and
Speech, the research of plant oil base lubricating additive is relatively fewer.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art there is provided antifriction antiwear type lubricating oil additive and its preparation side
Method.
To reach above-mentioned purpose, the present invention is achieved through the following technical solutions.
The preparation method of antifriction antiwear type lubricating oil additive, comprises the following steps：
1) Feedstock treating：Cape jasmine is crushed or smashed；
2) pressurised extraction：The raw material after processing is put into pressure pan, adds the pure water of identical weight, be forced into
4kgf/cm2, make its pressure uniform, and 15-20min is kept, momentary recovery normal pressure, filtering obtains extract solution, concentrates, must soak
Cream；
3) aqueous two-phase extraction：To step 2) medicinal extract progress aqueous two-phase extraction is obtained, medicinal extract and aqueous two-phase extraction liquid are according to 1:
1.5 volume ratio, obtains organic phase and aqueous phase, double-aqueous phase system used in aqueous two-phase extraction by polyethylene glycol, sodium chloride and
Water is constituted, and mass percent of the polyethylene glycol in the double-aqueous phase system is 15-25%, and sodium chloride is in the double-aqueous phase system
In mass percent be 10-15%, surplus is water, and the weight average molecular weight of the polyethylene glycol is 6000-8000；
4) post-process：By step 3) obtain extraction organic phase, desalination, vacuum distillation remove moisture, obtain yellow transparent oil
Shape liquid, obtains product.
Step 2 of the present invention) described in concentration, be preferably concentrated into 0.95-1.05g/ml.
Step 4) described in desalination, it is preferred to use ultrafiltration or dialysis desalination, ultrafiltration use molecular cut off for
1000-100000 milipore filter desalination, dialysis uses molecular cut off for 1000-100000 bag filter desalination.
The invention further relates to the antifriction antiwear type lubricating oil additive obtained using above-mentioned preparation method.
Compared with prior art, the advantage of the invention is that：
1st, contain substantial amounts of grease in the plant cell of cape jasmine, mainly by composition for triglycerides compound group into it is mixed
Compound, these greases with elaioleucite and oil body protoplast form, in discontinuous graininess, together with granule protein body irregularly
The scattered existence form such as in the cell is present.In plant extract, substantial amounts of vegetable fat can be discharged, and cape jasmine plant carries
Thing is taken, usually using water miscible part, therefore, in extraction process, the aqueous phase after aqueous two-phase extraction is mainly used, and
Organic phase (oil phase) after aqueous two-phase extraction, is discharged, applicant is produced using cape jasmine plant extract after usually handling
Raw organic phase, for antifriction antiwear type lubricating oil additive, can not only obtain new antifriction antiwear type lubricating oil additive,
Disposal of pollutants can also be reduced, is killed two birds with one stone.
2nd, the present invention is during pressurised extraction, and pressure used is far smaller than the high pressure extraction pressure in plant extract technology
Power, it is therefore intended that discharge the grease in plant, rather than gone with bigger pressure to extract the active component of plant, cause high pressure
The product of extraction is complicated, the same complicated component in later stage aqueous two-phase extraction, so as to influence the quality of final products.
3rd, the antifriction antiwear type lubricating oil additive that the present invention is obtained, under the conditions of different load, concentration, temperature etc.
Tribological property is significantly improved.
