Description

One vegetable oil based high-temp-resistant lubricating oil and preparation method thereof
Technical field
The present invention relates to technical field of lubricating oil, and in particular to a vegetable oil based high-temp-resistant lubricating oil and its preparation side Method.
Background technique
Currently, in industries such as chemical industry, weaving, machinery, lubricating oil is widely used.With further pushing away for economic globalization Extensively, the especially rapid development of auto industry, and environmental protection, the reinforcement of power conservation requirement, although the total amount supply of lubricating oil is not It increases considerably, but increasingly vigorous to the demand of top-grade lubricating oil.Lubricating oil is mainly by base oil and additive two Part forms, and wherein base oil is the main component of lubricating oil, accounts for about 85% or more.
Lube base oil is divided into vegetable oil, mineral oil and synthetic oil, and vegetable oil has biodegradable characteristic, to environment It pollutes lower, is the advantage that mineral oil and most of synthetic oils do not have.Today's society has higher requirement for environmental protection, and The These characteristics of vegetable oil conform exactly to the demand of environmental protection.Although the production cost of vegetable oil is higher, it has low The advantages of pollution, greatly reduces its investment in environmental pollution improvement, therefore has vast market prospect.
But existing vegetable oil based lubricating oil high temperature resistance is bad, additive dispersion is uneven, in mechanical friction process In, it is easy to happen oxidation deterioration, and high production cost, therefore cause vegetable oil based lubricating oil use scope limited, cannot advised greatly Mould application.
Summary of the invention
To solve the problems, such as that current vegetable oil based lubricating oil exists, the present invention provides a kind of low in cost, safety and environmental protection, tool There is the vegetable oil based lubricating oil of high temperature resistant, self-repair function, anti-attrition anti-wear effect is significant, and various fields is suitble to apply.
To reach the purpose, the technical scheme adopted by the invention is that:
One vegetable oil based high-temp-resistant lubricating oil, is to be made of raw material from the following weight: 20-40 parts of corn oil, castor-oil plant 10-15 parts of 12-18 parts oily, hydroxy-end capped dimethyl diphenyl polysiloxanes, 3-5 parts of polyvinyl alcohol, 3-7 parts of ethanol amine, poly- second 4-8 parts of glycol monomethyl ether, 1-3 parts of ferrocene, 1-3 parts of preservative, 3-5 parts of composite stone ink powder, modified manometer silicon dioxide 2-5 Part.
Preferably, the vegetable oil based high-temp-resistant lubricating oil, is to be made of raw material from the following weight: 40 parts of corn oil, 18 parts of castor oil, 15 parts of hydroxy-end capped dimethyl diphenyl polysiloxanes, 5 parts of polyvinyl alcohol, 7 parts of ethanol amine, polyethyleneglycol 8 parts of methyl ether, 3 parts of ferrocene, 3 parts of preservative, 5 parts of composite stone ink powder, 5 parts of modified manometer silicon dioxide.
The composite stone ink powder is prepared by following methods: after paraffin section, being placed in electrically heated drying cabinet, is increased Temperature, after melting paraffin sufficiently, heat preservation the graphite powder of quality such as is added, is stirred evenly using graphite powder, quiet at room temperature It crushed 200 meshes after setting cooling, obtain the composite stone ink powder of paraffin modification.
The modified manometer silicon dioxide is obtained by following methods preparation:
(1) by 165g ethyl orthosilicate, 1300g dehydrated alcohol, 40g deionized water and 9g NH3·H2O is added in beaker, Colloidal sol is aged 7d under conditions of 30 DEG C after magnetic agitation 2h at 30 DEG C, reflux removes the ammonia in colloidal sol, it is molten to obtain SiO2 Glue；
(2) SiO obtained by 100g step (1) is taken2Colloidal sol is added in vial, is heated to 35 DEG C, then into glass reagent bottle Two silicon azepine alkane of hexamethyl is added, is aged 5d after 2h is sufficiently stirred under conditions of 35 DEG C again, controls two silicon azepine alkane of hexamethyl Dosage be SiO2SiO in colloidal sol22 times of quality, after ageing, obtain modified nano silica.
The preservative is that potassium sorbate and sodium benzoate are obtained according to mass ratio 1:1.
The preparation method of one vegetable oil based high-temp-resistant lubricating oil, comprising the following steps:
(1) it prepares composite stone ink powder: after paraffin section, being placed in electrically heated drying cabinet, increase temperature, melt paraffin sufficiently After change, heat preservation the graphite powder of quality such as is added, is stirred evenly using graphite powder, stand at room temperature it is cooling after crushed 200 Mesh obtains the composite stone ink powder of paraffin modification；
(2) preparation is modified receives the wooden silica: by 165g ethyl orthosilicate, 1300g dehydrated alcohol, 40g deionized water and 9g NH3·H2O is added in beaker, and colloidal sol is aged 7d under conditions of 30 DEG C after magnetic agitation 2h at 30 DEG C, and reflux removes Ammonia in colloidal sol, obtains SiO2Colloidal sol；Take SiO obtained by 100g2Colloidal sol is added in vial, is heated to 35 DEG C, then to glass reagent Two silicon azepine alkane of hexamethyl is added in bottle, is aged 5d after 2h is sufficiently stirred under conditions of 35 DEG C again, controls two silicon nitrogen of hexamethyl The dosage of miscellaneous alkane is SiO2SiO in colloidal sol22 times of quality, after ageing, obtain modified nano silica；
(3) corn oil, castor oil is added in a kettle by weight, is heated to 80-90 DEG C under stirring, constant temperature shape Under state, hydroxy-end capped dimethyl diphenyl polysiloxanes, polyvinyl alcohol, ethanol amine, polyethyleneglycol are sequentially added by weight Methyl ether, ferrocene, preservative, heat preservation magnetic agitation dissolve 1-3h, obtain just mixed liquid；
(4) step (3) gained is just mixed into liquid and is cooled to 50-60 DEG C, addition composite stone ink powder under magnetic agitation, 65 DEG C of constant temperature 12h is stirred, modified nano silica is then added, stirs for 24 hours, be cooled to room temperature at 55 DEG C, obtain finished product.
Heating temperature is greater than 70 DEG C in step (1), to guarantee that paraffin sufficiently melts.
Paraffin used in the present invention is commercially available gained, produces phase change paraffin, phase transformation for Shanghai Ru Shang new energy scientific & technical corporation Temperature range is 20-28 DEG C, latent heat of phase change about 230J/g, and thermal coefficient is about other raw material used in 0.15W/ (mK) this hair It is commercially available.
The utility model has the advantages that the present invention is basic crude oil with vegetable oil such as corn oil, castor oil, the graphite of paraffin modification is added Powder, during mechanical friction, can effective Fast Filling frictional contact surface mechanical damage, while in temperature arrising caused by friction process In, it is paraffin melting especially under high temperature friction environment, it promotes graphite and plays heat-conducting effect, there is the effect for reducing frictional surface temperature Fruit extends the service life of lubricating oil to a certain degree.Meanwhile the present invention also added modified nano silicon dioxide sol, Oleophylic is carried out to it using two silicon azepine alkane of hexamethyl to be modified, and is promoted its dispersion in base oil, is reduced the reunion of particle, match Modified graphite powder is closed, reparation damage is played in friction process, gives full play to the effect of antiwear and reducing friction.The two is mutually promoted, altogether With realizing the wear-resistant technical effect of lubricating oil high temperature resistant of the present invention, efficient anti-attrition, and preparation process is simple, low in cost, tool Be widely used potentiality.
