Embodiment 1

[0036] An SP grade gasoline engine oil in this embodiment is composed of the following raw materials in mass percentage: Lubrizol PV1410: 7.9% for gasoline engine oil compounding agent; Infineum SV260: 8% for viscosity index improver; RIPP for pour point depressant -T866: 0.3%; base oil A uses PAO 164: 17.6%; base oil B uses PAO 166: 66.2%.

[0037] The preparation method is as follows: add the above-mentioned components in the order of the order of the ingredients into the blending kettle, raise the temperature to 60°C, heat and stir for 1.5 hours, until the components are mixed evenly and the appearance is clear, filter while it is hot, and cool to room temperature. Promptly get described SP grade gasoline engine oil, the performance index of gained product is detected, and detection result is as follows: figure 1 shown.

Embodiment 2

[0039] A kind of SP grade gasoline engine oil of the present embodiment is made up of the raw material of following mass percentage: Gasoline engine oil compounding agent adopts Lubrizol PV1410: 12%; Viscosity index improver adopts Chevron 8900E: 7.5%; Kex 1-248: 0.5%; base oil A selection of 4CST: 30%; base oil B selection of PAO 166: 50%.

[0040] The preparation method is as follows: add the above-mentioned components in the order of the order of the ingredients into the blending kettle, raise the temperature to 55°C, heat and stir for 1.5 hours, until the components are mixed evenly and the appearance is clear, filter while it is hot, and cool to room temperature. That is, the SP grade gasoline engine oil is obtained, and the performance index of the product obtained is detected, and the detection results are basically as in Example 1.

Embodiment 3

[0042] An SP grade gasoline engine oil of this embodiment is composed of the following raw materials in mass percentage: gasoline engine oil compounding agent adopts Lubrizol PV1510: 5%; viscosity index improver adopts Infineum SV260: 4.9%; pour point depressant adopts Roman X 1-300: 0.1%; base oil A uses X420: 10%; base oil B uses 6CST: 80%.

[0043] Its preparation method is as follows: add the above-mentioned components into the blending kettle in sequence according to the order of the components, raise the temperature to 45°C, heat and stir for 1 hour, until the components are mixed evenly and the appearance is clear, filter while it is hot, and cool to room temperature. Obtain described SP grade gasoline engine oil, the performance index of gained product is detected, and detection result is basically as embodiment 1.

Abstract

The invention discloses SP-grade gasoline engine oil and a preparation method thereof, and belongs to the technical field of lubricating oil. The gasoline engine oil comprises the following raw materials in percentage by mass: 5%-12% of a gasoline engine oil complexing agent; 4%-10% of a viscosity index improver; 0.1%-0.5% of a pour point depressant; 10%-30% of base oil A; and 50%-80% of base oil B. The preparation method comprises the following steps: sequentially adding the pour point depressant, the viscosity index improver, the gasoline engine oil complexing agent, the base oil A and the base oil B into a blending kettle, uniformly conducting mixing, and conducting stirring and filtering to obtain the SP-level gasoline engine oil. By adopting the technical scheme of the invention, a product with excellent comprehensive performance can be obtained, the viscosity-temperature performance is higher, the low-temperature fluidity is more excellent, the fuel economy is better, the shearing resistance is better, the important progressive significance is realized, and better protection is provided for a novel engine adaptive to National Six Emission Regulations.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and more specifically relates to an SP grade gasoline engine oil and a preparation method thereof. Background technique [0002] In order to cope with the increasingly stringent environmental protection regulations and energy-saving requirements promulgated by the country, and to meet the National VI emission standards, automobile manufacturers adopt engine miniaturization, direct injection technology, increase turbocharging, reduce friction, and exhaust after-treatment and combustion technologies, etc. , to further improve the fuel economy of the vehicle and meet emission requirements. For passenger cars, according to the trend of traditional power systems, from the previous large displacement, gradually replaced by small displacement, 2.0 has gradually developed into 1.6L, 1.5L, 1.3L, from natural aspirated to turbocharged. pressure. These changes require higher-quality lubricants to ...
