Abstract
The invention provides an engine oil composition and a preparation method thereof. The preparation method can reduce damage of an engine oil composition containing a metal oxide as an anti-wear additive due to contact with an oil-soluble solvent.
Description
Technical Field
The present invention relates to an engine oil composition, and more particularly to an engine oil composition prepared by mixing an aqueous sol of a metal oxide with an engine oil.
Background
The engine oil is added into the gasoline cylinder, so that all components of the engine can be kept lubricated, corrosion and rust are avoided, and the vehicle engine can be kept to operate smoothly. Known engine oils mostly contain two components, i.e., a base oil for maintaining lubrication between components and an additive for compensating for the deficiencies of the components of the base oil in the existing properties or for providing additional functions, e.g., as an auxiliary additive such as a detergent, a dispersant, an antioxidant, an anti-rust or anti-corrosion additive, a viscosity or flow improver, or an anti-wear additive.
The above additives are usually prepared by dissolving the main component in an organic solvent (specifically, an oil-soluble solvent). For example, titanium dioxide is believed to have a particle size that is better suited as an anti-wear additive to fill the crevices of a cylinder. Currently, the titanium dioxide-containing engine oil is prepared by mixing titanium dioxide powder with an oil-soluble solvent (for example, an aromatic or high carbon solvent, liquid paraffin, or mineral oil) and further adding the mixture to the engine oil. However, the titanium dioxide powder added at present is mostly in micron-sized, the effect only focuses on removing carbon slag, so that gaps are difficult to be effectively filled, and the adsorption force on the cylinder wall is poor, so that the durability is poor. In addition, the continuous presence of organic solvents in engine oils may damage the properties of the base oil or increase the possibility of damaging other additives, thereby changing the dynamic viscosity of the oil and causing damage to the cylinder.
Disclosure of Invention
In view of the foregoing, the inventors of the present invention have made extensive studies and thought to design an engine oil composition and a method for preparing the same, in which nano-scale metal oxides are used to replace known micron-scale anti-wear additives, and oil-soluble solvents are not used, thereby improving the shortcomings of the prior art and further enhancing the industrial application.
In view of the above-mentioned known problems, the present invention provides an engine oil composition and a method for preparing the same, which can prepare an engine oil composition having a good gap filling effect and reduce the possibility of damage to the engine oil composition caused by the oil-soluble solvent in the known additive.
In view of the above object, the present invention provides a method for producing an engine oil composition, comprising: dispersing a metal oxide in a polar liquid medium to form an aqueous sol; mixing machine oil with the aqueous sol to prepare a machine oil mixture; and performing vacuum pumping on the engine oil mixture to remove the polar liquid medium to obtain the engine oil composition, wherein the metal oxide comprises titanium dioxide, aluminum oxide or silicon dioxide, and the polar liquid medium comprises water or an alcohol solvent.
Preferably, the engine oil and the aqueous sol are mixed in a ratio of 70g to 90g, 5mg to 30 mg.
Preferably, the polar liquid medium comprises water, methanol, ethanol, isopropanol, or a combination thereof.
Preferably, the metal oxide may comprise 0.1% to 10% by total weight of the aqueous sol.
Preferably, the particle size of the metal oxide in the aqueous sol is 1nm to 500 nm.
In view of the above object, the present invention further provides an engine oil composition prepared by the above preparation method.
In view of the above, the engine oil composition and the preparation method thereof according to the present invention may have one or more of the following advantages:
(1) the metal oxide is prepared in the polar liquid medium, and the polar liquid medium is removed in vacuum after the metal oxide is added into the engine oil, so that the metal oxide is kept in the engine oil to be used as an anti-wear additive, and the opportunity that an oil-soluble solvent contacts the engine oil is reduced.
(2) The engine oil composition of the invention fills the nicks generated by abrasion in the gasoline cylinder by the metal oxide in the engine oil composition, and when the gasoline cylinder is heated, the metal oxide forms compact oxide films in the nicks, thereby reducing the chance of scratching again.
In order to make the above objects, technical features and gains obvious and understandable after practical implementation, preferred embodiments will be described in more detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a flow chart of the steps for preparing an engine oil composition according to the present invention.
Detailed Description
Referring to fig. 1, which is a flow chart illustrating the steps of preparing the engine oil composition according to the present invention, the steps of preparing the engine oil composition according to the present invention may include the following steps.
In step S10, a metal oxide is dispersed in a polar liquid medium to form an aqueous sol, wherein the metal oxide may comprise titanium dioxide, aluminum oxide or silicon dioxide, and the metal oxide may form an aqueous sol after dispersion, wherein the content of the metal oxide is 0.1% to 10% (w/w) based on the total weight of the aqueous sol, but is not limited thereto, for example, in consideration of the following step S30, an aqueous sol containing 0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1%, 1.5%, 2%, 2.5%, 3%, 4%, 5%, 6%, 6.5%, 7%, 7.5%, 8%, 9%, 10% (w/w) of the metal oxide based on the total weight of the aqueous sol may be prepared.
The medium for dispersing the metal oxide may be water or polar liquid medium of alcohol, and the alcohol medium may be lower alcohols of methanol, ethanol, propanol, isopropanol, or a combination thereof, but the embodiment is not limited thereto. In practice, the polar liquid medium referred to herein is a liquid in which the metal oxide can be dispersed to form an aqueous sol.
In step S20, the machine oil and the aqueous sol may be mixed to prepare a machine oil mixture. The mixing ratio of the engine oil and the aqueous sol may be 70g to 90g, 5mg to 30mg, preferably 70g to 90g, 5mg to 15 mg. Preferably, the above-mentioned mixing is carried out by mixing the engine oil in an amount of 70g, 75g, 80g, 85g or 90g with the aqueous sol in an amount of 5mg, 6mg, 7mg, 8mg, 10mg, 11mg, 12mg, 14mg or 15 mg.
In step S30, the oil mixture may be vacuum pumped to remove the polar liquid medium to obtain the oil composition. The vacuum pumping is for removing the polar liquid medium in the oil mixture, but the implementation is not limited thereto. Furthermore, it has been demonstrated in the experimental examples of the present invention that the object of the present invention can be achieved without completely removing the polar liquid medium if the content of the aqueous sol in the engine oil mixture is less than a certain level.
In practice, the particle size of the metal oxide in the aqueous sol may be 1nm to 500nm, preferably 1nm to 100nm, more preferably 30nm to 50nm, so as to fill up the nicks in the cylinder caused by the abrasion of impurities.
The invention further provides the engine oil composition prepared by the method. According to the characteristics of the titanium dioxide, the alumina or the silicon dioxide in the form of the aqueous sol, the engine oil composition can be added into the gasoline cylinder during cold running, and after the nicks in the gasoline cylinder are filled by the metal oxide, the metal oxide can form a compact oxide film in a high-heat environment, so that the re-scratching is reduced.
The following are specific embodiments of titanium dioxide as the metal oxide, however, the preparation conditions indicated below are also applicable to alumina or silica.
[ Experimental example 1]
Dispersing titanium dioxide with the particle size of 10 nm-100 nm in alcohol solution to form aqueous sol, wherein the content of the titanium dioxide is 0.1% -5% (w/w) based on the total weight of the aqueous sol. The engine oil and the water sol are mixed according to the proportion of 80g to 5mg, and after the mixture is mixed evenly, the machine oil composition is prepared by pumping out alcohol by vacuum pumping.
[ Experimental example 2]
The same conditions as in Experimental example 1 were used except that the engine oil and the aqueous sol were mixed at a ratio of 80g to 15 mg.
[ Experimental example 3]
The same conditions as in Experimental example 1 were used except that the engine oil and the aqueous sol were mixed at a ratio of 80g to 25 mg.
Comparative example 1
Comparative example 1 is a group using only engine oil.
Comparative example 2
The same conditions as in Experimental example 1 were used except that the engine oil and the aqueous sol were mixed at a ratio of 80g:2 mg.
The engine oil composition is replaced at the top 100km of the recommended kilometers for replacing the original engine oil (i.e. the engine oil mentioned above), i.e. if the engine oil is recommended to be replaced when the kilometers reaches 1000km, the engine oil composition of the present invention should be replaced when the engine oil is cold when the engine oil travels 900 km. The pre-run was performed for 100km so that the titanium dioxide in the engine oil composition filled the notch, and then the time measurement of the acceleration was performed at a speed of 0km to 100km per hour, and the results are shown in the following table 1.
TABLE 1
| Sample (I) | Acceleration to 100km/hr in seconds |
| Comparative example 1 (Engine oil) | 6.5s |
| Comparative example 2 | 6.5s |
| Experimental example 1 | 6.3s |
| Experimental example 2 | 6.2s |
| Experimental example 3 | 6.4s |
The results show that the accelerated seconds of the experimental examples 1, 2, 3 are all lower than the comparative example 1 and also lower than the comparative example 2 outside the range of the present invention, wherein the experimental examples 1, 2 implemented according to the preferred parameters of the present invention have better effects. The above results show that the titanium dioxide in the engine oil composition of the present invention fills the cut in the gasoline cylinder, thereby reducing the resistance required for acceleration and allowing a predetermined speed to be reached in a shorter time.
The method for preparing the engine oil composition of the invention can keep the metal oxide in the engine oil without causing an oil-soluble solvent with high harmfulness. The above results also confirm that the titanium dioxide in the engine oil composition of the present invention can increase the lubrication degree of the gasoline cylinder, and make the engine more labor-saving during acceleration. In addition, the engine oil composition of the invention can form an oxidation protection film on the nicks in a high-temperature state because the particle size is small enough, so that the chance of forming the nicks by being scratched by impurities again is reduced.
The foregoing is by way of example only, and not limiting. It is intended that all equivalent modifications or variations without departing from the spirit and scope of the present invention shall be included in the appended claims.
