Embodiment 1

[0061] Preparation of steam engine oil compounding agent: Add 3kg of calcium alkylbenzene sulfonate and 1kg of calcium sulfide alkylphenate to 60kg of alkyl dibenzyltoluene and stir at 400 rpm for 10min, then add 6kg of borated polyisobutylene succinimide Rotate at a speed of 400 rpm and stir for 20 minutes to obtain the compound agent for gasoline and engine oil.

[0062] The synthetic base oil is prepared by uniformly mixing 37.7 kg of polyalphaolefin, 33 kg of dioctyl adipate, 10 kg of pentaerythritol tetramyristate, and 5.297 kg of 13-docosyl-13-docosyl ester.

[0063] Ultra-low viscosity energy-saving gasoline engine oil raw materials: 10kg gasoline engine oil compounding agent, 0.3kg antioxidant, 1.5kg hydrogenated styrene-isoprene copolymer, 1.5kg ethylene-propylene copolymer, molybdenum diisooctyl dithiocarbamate 0.35kg, amino diisopropyl tungsten dithiophosphate 0.05kg, simethicone oil 0.003kg, synthetic base oil 85.997kg.

[0064] The antioxidant consists of 0.1kg2,...

Embodiment 2

[0067] The energy-saving gasoline engine oil of ultra-low viscosity is prepared by the method for embodiment 1, difference only is: described antioxidant is made of 0.15kg2,4-dimethyl-6-tert-butylphenol, 0.15kg2,2'-methylene Bis-(4-methyl-6-tert-butylphenol) composition. Obtain the ultra-low viscosity energy-saving gasoline engine oil of embodiment 2.

Embodiment 3

[0069] The ultra-low viscosity energy-saving gasoline engine oil was prepared according to the method of Example 1, the only difference being that the antioxidant was composed of 0.15kg 2,4-dimethyl-6-tert-butylphenol and 0.15kg dioctyl diphenylamine. Obtain the ultra-low viscosity energy-saving gasoline engine oil of embodiment 3.

Abstract

The invention discloses ultra-low-viscosity energy-saving gasoline engine oil and a preparation method thereof. The ultra-low-viscosity energy-saving gasoline engine oil is composed of, by mass, 8.5-12.5% of a steam turbine oil complexing agent, 0.1-0.5% of antioxygen, 1-5% of viscosity index improver, 0-0.8% of an antiwear agent, 0.002-0.005% of an anti-foaming agent and the balance synthetic base oil. According to the base oil, alpha-olefin, esters and polyester oil are selected in cooperation with the special viscosity index improver, the mixture is combined and blended into ultra-low-viscosity totally-synthesized gasoline engine oil with the viscosity meeting the standard, characteristics of alpha-olefin type oil and ester type oil are utilized and reasonably matched, and the ultra-low-viscosity totally-synthesized gasoline engine oil which is excellent in performance is prepared; according to the ultra-low-viscosity energy-saving gasoline engine oil and the preparation method thereof, an anti-wear reinforcing agent is added to serve as oil soluble organic molybdenum and organic tungsten, the organic molybdenum and organic tungsten are used in a joint mode, engine oil plays good anti-wear and friction reduction functions in the whole stage of operation of an engine, the phenomena that the oil temperature is excessively high, and thus oil is oxidized and goes bad due to excessively high friction are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, and relates to an ultra-low viscosity energy-saving gasoline engine oil and a preparation method thereof. Background technique [0002] With the development of modern automobile technology and the improvement of environmental regulations, vehicles are required to have excellent driving performance and good fuel economy. There are generally three ways to improve fuel economy. First, improve fuel combustion performance, but it is difficult to significantly improve fuel combustion performance with current technology; second, change the structure of the engine to improve combustion performance, but the development of an engine requires It consumes a lot of manpower and material resources, and it is unreasonable to improve fuel economy through this; thirdly, improving fuel economy by improving the performance of engine oil is currently the most effective, simple and feasible method to reduce f...
