Description
Technical field
The invention belongs to chemical technology field, and in particular to a kind of environment-protective lubricant oil.
Background technology
Lubricating oil is used in all kinds automobile, plays lubrication, cooling, antirust, cleaning, sealing and buffering etc. in plant equipment
The liquid or semisolid lubricants of effect, protection machinery and workpiece.Typically it is made up of base oil and additive two parts.Basis
Oil is the main component of lubricating oil, decides the fundamental property of lubricating oil, and additive can then make up and improve base oil performance side
The deficiency in face, some new performances are assigned, be the important component of lubricating oil.Research has good antiwear and antifriction effect, together
When ensure its feature of environmental protection, ensure that lubricating oil and its loss product do not damage to ecological environment, or be ring to a certain extent
Border is allowed, and is the emphasis of current lubricating oil industry research, and the significant problem point faced.
The content of the invention
It is an object of the invention to provide a kind of environment-friendly lubricating oil, base oil selection vegetable oil, ensures antiwear and antifriction effect
While, there is good environment-friendly property.
The technical proposal of the invention is realized in this way：A kind of environment-friendly lubricating oil, base oil selection vegetable oil, its feature
It is, including following components by weight ratio：SULFURIZED CALCIUM ALKYL PHENATE WITH HIGH BASE NUMBER 2.5-3.8%, molybdenum dialkyl-dithiophosphate
0.1-0.8%, polyisobutene succinimide 3.5-4.5%, zinc dialkyl dithiophosphate 1.6-1.9%, dialkyl group hexichol
Amine 0.1-1.2%, low molecule amount polymethacrylates 0.1-0.36%, silicone emulsion 0.05-0.15%, ethylene propylene copolymer
Thing 1-13%, base oil 75-86%.
The SULFURIZED CALCIUM ALKYL PHENATE WITH HIGH BASE NUMBER：Serve in engine oil in acid and, it is anti-oxidant and wear-resistant.With good
Detergent-dispersant performance and water-resistance, acid neutralization capacity is stronger, and high temperature detergency is good, and water-resistance is good.For modulating medium and high classes internal combustion
Machine oil, be particularly suitable for use in pressurized diesel engine oil.Reduce the carbon deposit of top land.Tests prove that high base number in the technical program
Sulfenyl phenolate calcium content should be controlled between 2.5-3.8%.
The molybdenum dialkyl-dithiophosphate：It is a kind of new and effective antifriction and antiwear agentses, its typical chemical formula is
[(RO):Ps—s]:M0:SO, R represents carbon number as 3~8 straight chained alkyl or branched alkyl in formula；R be alternatively aryl or
Aralkyl, the carbon number of aryl is 6~26, and alkyl substituent carbon atom quantity is 4~9.In its molecular structure, each molybdenum
Atom is mutually bonded with a dialkyl dithiophosphoric acid base.Molybdenum dialkyl-dithiophosphate be mainly used as I. C. engine oil, hydraulic oil,
Air compressor oil, turbine machine oil, hypoid gear oil, the additive of rail oil and various intermetallic composite coating lubricating oil, mainly
Function is antifriction, wear-resistant and anti-oxidant etc. multiple functions, and is effectively saved the energy.Tests prove that two in the technical program
Alkyl dithiophosphoric acid molybdenum content should be controlled between 0.1-0.8%.
The polyisobutene succinimide：It is for raw material, using hot adduction work with high-activity polyisobutene (=1000)
Ashless dispersant prepared by skill.With good detergent-dispersant performance, the generation of carbon deposit and paint film on engine piston can be suppressed, produced
Product are not chloride.Experiment proves that polyisobutene succinimide content should be controlled between 3.5-4.5% in the technical program.
Zinc dialkyl dithiophosphate：Also known as accelerator ZDTP, molecular formula are C28H60O4P2S4Zn, and molecular weight is
716.3901 it is a kind of chemical intermediate.Be it is a kind of with antioxygen, anti-rotten and wear-resistant effect multipurpose additive, can press down
Paint film, greasy filth, the annular groove of engine motor oil processed stick the generation of thing, suppress oil product viscosity and increase, prevent cylinder, annular groove, cam
With the abrasion of valve rod, moreover it is possible to prevent bearing corrosion.Experiment proves that zinc dialkyl dithiophosphate content should be controlled in the technical program
System is between 1.6-1.9%.
The silicone emulsion：Have defoaming fast as anti-foaming agent, suds suppressing properties are good, do not influence the basic nature of bubbling system
Matter, diffusivity, good penetrability, chemical stabilization.Experiment proves that silicone emulsion content should be controlled in 0.05- in the technical program
Between 0.15%.
The ethylene propylene copolymer：As thickening agent, usually it is dispersed in fluid lubricant and is formed with colloidal state
Space net structure, or be only dispersed in the form of dispersed phase in base oil, play a part of adsorbing and limit base oil flowing.
Thickening agent directly affects the performances such as the mechanical stability of lubricating grease, heat-resisting quantity, colloid stability, water-resistance.Experiment proof, this
Ethylene propylene copolymer content should be controlled between 1-13% in technical scheme.
Oil based on the vegetable oil of lubricating oil selection environmental protection provided by the invention, additive level is few, while has good
The characteristics of inoxidizability well, wear resistence, detergency and good dispersion, there is higher economic value and social value, be easy to
It is extensive to promote and use.
