Embodiment 1

[0024] A preparation method of special oil for a racing car engine, comprising the steps of:

[0025] (1) Weigh 300kg of polyalphaolefin synthetic base oil PAO150, 367kg of PAO8 and 100kg of pentaerythritol ester into a blending kettle with stirring function, heat to 55°C and stir evenly;

[0026] (2) Keep stirring, weigh 15kg of α-naphthylamine, 20kg of methyl borate, 10kg of barium stearate, 20kg of calcium alkyl salicylate, 5kg of benzotriazole, 3kg of polymethyl methacrylate and formaldehyde Slowly add 0.2kg of base silicone oil into the blending kettle, raise the temperature to 65°C, and continue to stir at a constant temperature for 0.5h.

Embodiment 2

[0028] A preparation method of special oil for a racing car engine, comprising the steps of:

[0029] (1) Weigh 350kg of polyalphaolefin synthetic base oil PAO150, 300kg of PAO8 and 100kg of pentaerythritol ester into a blending kettle with stirring function, heat to 56°C and stir evenly;

Abstract

The invention provides oil special for a top-speed racing car engine and a preparation method thereof. The oil special for the top-speed racing car engine is prepared from the following components inparts by weight: 52-66.7 parts of poly-alpha olefin synthetic base oil, 10-15 parts of ester base oil, 1.5-3 parts of a high-temperature antioxidant, 1-3 parts of a friction modifier, 1-2 parts of anashless dispersant, 1-2 parts of a cleaning agent, 0.05-0.5 part of a corrosion inhibitor, 0.5-1 part of a pour point depressant and 0.02-0.09 part of a defoaming agent. The preparation method for the oil special for the top-speed racing car engine is simple, a unique formula composition effectively achieves the synergistic effect among additives, excellent high-and-low temperature performance, good oil film strength, excellent adhesion performance and excellent friction resistance and abrasion resistance are achieved, the performance requirements of the racing car engine oil under the limited working condition can be met, and meanwhile, the oil replacement period and the service life of the engine are effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a special oil for a racing car engine and a preparation method thereof. Background technique [0002] The engine is the heart of the car. During the high-speed operation of the engine, many metal parts contact and rub against each other, which will generate huge heat. The operating temperature can reach 400°C to 600°C. Such harsh working conditions cause the engine parts to wear easily and seriously affect the service life. . Engine oil, also known as engine lubricating oil, is known as the "blood" of a car. Engine oil with excellent performance can lubricate and reduce engine friction, assist cooling and cooling, seal and prevent leakage, prevent rust and corrosion, shock absorption and buffering, etc. [0003] From the perspective of engine principle, the engine of a racing car is no different from that of an ordinary car, both of which use the principle of...
