Description
Technical field
The present invention relates to lubricating oil fields, and in particular to be a kind of lubrication oil composite type demulsifier and preparation method thereof and
Using.
Background technology
Lubricating oil is made of base oil and additive two parts, and base oil is the main component of lubricating oil, decides profit
The fundamental property of lubricating oil, additive can then make up and improve the deficiency of base oil aspect of performance.Institute of the additive in lubricating oil
Accounting example is smaller, and maximum is usually no more than 30%, is less than 1% in the iundustrial oil of part.And lubricating oil complexing agent is that have to assign
Give the no property/performance of base oil itself, such as anti-bubble, demulsification performance；Original property/the performance of base oil can be improved,
Such as wear-resistant, antirust performance.
It is some iundustrial oils such as industrial gear oil, liquid contacted with water that demulsifier, which is also anti emulsifier, demulsibility,
One of critically important performance such as pressure oil and steam turbine oil.Lube oil emulsion resistant agent is mainly used for modulating gear oil, steam turbine oil etc.
All types of industries oil, for improving oil product in Duo Shui, the resistance to emulsion of heavy load.It is comprehensive to have domestic and international patent and text
Report is offered, lube oil emulsion resistant agent product is still with epoxy ethane-epoxy propane block co-polyether and nitrogenous polyether-modified at present
Based on high-molecular compound.
Since demulsifier has certain scope of application, gene basis oil source variation sometimes, production technology adjustment, operation item
Part fluctuates and causes the micro change of oil base stock composition；Or the superficiality of oil product is changed because of the use of multiple additives
Can, so that causing the variation of oil product demulsification performance, make individually to use demulsifier, it is difficult to the demulsification performance of lubricating oil product be made to reach
To expected effect.Therefore it provides a kind of composite demulsifying agent is imperative.Such as the middle promulgated by the State Council of Publication No. CN101619257A
Bright to disclose a kind of lubricant anti-emulsifier composition, the composition is by (1) alkylene diamine oxozone trimethylene derivative and (2)
SYNPERONIC PE/F68 forms, and the mass ratio of component (1) and component (2) is 40: 60~80: 20, the technical solution
The only combination of two kinds of demulsifiers can not solve the problems, such as that simple demulsifier exists.
Invention content
It is difficult to the deficiency for making the demulsification performance of lubricating oil achieve the desired results for existing single anti emulsifier, the present invention
It is intended to provide a kind of lubrication oil composite type demulsifier, to improve the demulsification performance of lubricating oil.The present invention also provides the lubrications
The preparation method application of oil composite type anti emulsifier.
To achieve the purpose of the present invention, inventor provides the following technical solution：
First, the present invention provides a kind of lubrication oil composite type demulsifiers, by solvent, viscosity index improver, demulsifier
It is formed with nano-solid additive, wherein solvent is one or more in rubber industry solvent naphtha, aviation kerosine, pentanone,
Viscosity index improver is polymethacrylates (PMA), ethylene-propylene copolymer (OCP), polyisobutene (PIB) or hydrogenated styrene
One or more in isoprene copolymer (HSD), demulsifier is polyethers demulsifier, and nano-solid additive is that nanometer is light
Matter activated Calcium carbonate, wherein solvent composition mass percent proportioning are 60-90%, viscosity index improver constituent mass percentage
Proportioning is 3-10%, and demulsifier components mass percent proportioning is 5-25%, and nano-solid additive component mass percent is matched
Than for 2-8%.
Demulsifier and viscosity index improver the study found that is compounded and is added the nano-solid addition of appropriate amount by inventor
Agent enhances the water repelling property of lubricating oil as anti emulsifier, can significantly improve the demulsification performance of lubricating oil, and to profit
Other performances of lubricating oil do not influence.
Preferably, heretofore described polymethacrylates (PMA) selects T602, ethylene-propylene copolymer (OCP) choosing
With T614, polyisobutene (PIB) selects Jinzhou essence to join JINEX6130, and hydrogenated styrene isoprene copolymer (HSD) selects brocade
State essence joins JINEX9900.
Preferably, heretofore described nanometer light activated Calcium carbonate grain size is between 10-40nm.
Preferably, heretofore described demulsifier is T1001.
The present invention also provides the preparation methods of above-mentioned composite demulsifying agent, include the following steps：
Demulsifier is measured according to the ratio with viscosity index improver first and is mixed, solvent is added, at a temperature of 20 DEG C -50 DEG C,
Mechanically or manually stirring and dissolving, then adding nano-solid additive makes it be sufficiently mixed uniformly, and it is broken to be made into lubrication oil composite type
Emulsion.
The present invention also provides the applications of above-mentioned composite demulsifying agent, operate as follows：In use, by requirement
Lubrication oil composite type demulsifier is added in oil product, is stirred evenly.The oil product be iundustrial oil, as industrial gear oil,
Hydraulic oil and steam turbine oil etc..Usually added according to the 0.1-1% of oil quality.
Compared with prior art, the present invention has the following advantages：
The present invention efficiently solves single anti emulsifier and is difficult to make the demulsification performance of lubricating oil product to get a desired effect
The problem of, compound anti emulsifier of the invention has preferable water repelling property, substantially increases the demulsification performance of lubricating oil.
Raw material of the present invention are easy to get, and preparation method is simple, and industrialization promotion is suitble to use.
Specific implementation mode
With reference to embodiment, present disclosure is further illustrated.It should be appreciated that the implementation of the present invention is not limited to
In the following examples, the accommodation in any form and/or change made to the present invention fall within the scope of the present invention.
In the present invention, if not refering in particular to, all equipment and raw material etc. are commercially available or the industry is common.
Method in following embodiments is unless otherwise instructed the conventional method of this field.
The present invention is carried out about the assessment method of lubricating oil demulsification performance by GB/T 7305-1989, i.e. oil and synthesis
Liquid resistance to emulsion pipette method.It is 30~100mm that this method, which is suitable for (40 DEG C) of kinematic viscosity,2The oil product of/s, or (82 ± 1)
℃.Concrete operation method be materials in graduated cylinder as defined in each 40mL charging methods of distilled water, under measuring temperature, with
The rotating speed of 1500r/min stirs 5min, keeps standing later, and start timing, record Synthesis liquid, water and remaining emulsion volume
Time when 40mL, 37mL, 3mL or 40mL, 40mL, 0mL is respectively reached, the time used is shorter, illustrates the resistance to emulsion of oil product
It can be better.If after standing 30min (when test temperature be (54 ± 1) DEG C) or 1h (when test temperature be (82 ± 1) DEG C), it is oily with
Water can't be completely separable, then reports the ml of oil or Synthesis liquid, water and remaining emulsion volume.Reaching 40-37-3mL is
It is basically separated qualification, it is to be kept completely separate to reach 40-40-0mL.
