Embodiment 1

[0021] ①Crush the beryl stone until the particle size is no more than 6 microns, and dry it at 110°C for 1 hour;

[0022] ② Weigh 7g of green cone stone obtained in step ①, 80g of diesel engine oil, 1g of aluminum powder, and 1g of alkylphenol polyoxyethylene ether and mix them into the closed device to make the vacuum degree reach -0.08MPa;

[0023] ③Raise the temperature to 85°C, stir at 10000rmp for 10min, adjust the rotation speed to 18000rmp for 6min, and adjust the rotation speed to 28000rmp for 4min;

[0024] ④ Finely disperse in a 1KW ultrasonic generator for 20 minutes.

[0025] The prepared new lubricant was tested on the MMW-1 vertical universal friction and wear machine with a test force of 800N and a speed of 600r / min. After 5 hours of wear test, the microhardness of the wear surface of the sample is HV1126. The weight loss of the sample from 2.9546g to 2.9548g is -0.026%, which means that the sample not only does not decrease, but also increases in weight. The...

[0027] ①Crush the beryl stone until the particle size is no more than 6 microns, and dry it at 110°C for 1 hour;

[0028] ②Weigh 8g of green cone stone obtained in step ①, 85g of diesel engine oil, 2g of aluminum powder, 1.3g of alkylphenol polyoxyethylene ether and mix them into the closed device to make the vacuum degree reach -0.08MPa;

[0029] ③Raise the temperature to 85°C, stir at 10000rmp for 10min, adjust the rotation speed to 18000rmp for 6min, and adjust the rotation speed to 28000rmp for 4min;

[0030] ④ Finely disperse in a 1KW ultrasonic generator for 20 minutes.

[0031] The prepared new lubricant was tested on the MMW-1 vertical universal friction and wear machine with a test force of 800N and a speed of 600r / min. After 5 hours of wear test, the microhardness of the worn surface of the sample is HV1156. The weight loss of the sample from 2.9580g to 2.9583g is -0.038%, which means that the sample not only does not decrease, but also increases in weight. The co...

[0033] ①Crush the beryl stone until the particle size is no more than 6 microns, and dry it at 110°C for 1 hour;

[0034] ②Weigh 9g of green cone stone obtained in step ①, 90g of diesel engine oil, 3g of aluminum powder, and 2g of alkylphenol polyoxyethylene ether and mix them into the closed device to make the vacuum degree reach -0.08MPa;

[0035] ③Raise the temperature to 85°C, stir at 10000rmp for 10min, adjust the rotation speed to 18000rmp for 6min, and adjust the rotation speed to 28000rmp for 4min;

[0036] ④ Finely disperse in a 1KW ultrasonic generator for 20 minutes.

[0037] The prepared new lubricant was tested on the MMW-1 vertical universal friction and wear machine with a test force of 800N and a speed of 600r / min. After 5 hours of wear test, the microhardness of the wear surface of the sample is HV1137. The weight loss of the sample from 2.9637g to 2.9646g is -0.030%, which means that the sample not only does not decrease, but also increases in weight. The ...

Abstract

The invention relates to a CD grade diesel engine oil composition, which comprises components of the following weight portions: 80-90 of CD diesel engine oil, 6-9 of cronstedtite, 1-3 of aluminum powder and 1-2 of alkylphenol polyoxyethylene ether. A superhard wear resistant layer is formed in a cylinder and on a piston ring of an engine through the prepared CD grade diesel engine oilcomposition and has extremely high corrosion resistance so that the engine can maintains the effective power, PM2.5 particulate matter emissions in the exhaust gas can be reduced, and the service life of the diesel engine can be prolonged. Moreover, the lubricating materials can be saved, and the effects of environmental protection can be realized. The raw materials for the product can be obtained easily, the formula is scientific, the production process is simple, the cost is low, the performance is good, and the product is suitable for turbocharged and supercharged diesel engine vehicles operating under harsh lubricating conditions.

Description

technical field [0001] The invention relates to a novel CD-type diesel engine oil composition, in particular to an extreme-pressure anti-wear composition for medium- and high-pressure diesel vehicle engines working under severe lubricating conditions, and belongs to the field of material technology. Background technique [0002] Diesel engines are mainly used for trucks of medium tonnage and above. Since the working principle of the diesel engine is compression ignition, the soot generated by the engine during operation will form deposits in the piston ring area; the sulfur content of diesel is 10 times that of gasoline, and the sulfur content of residual diesel engine fuel is 10 times that of gasoline More than 100 times of that, when diesel fuel is burned, high sulfur content will cause corrosion and wear of piston rings and cylinder liners, and sulfuric acid produced by sulfur can also accelerate the formation of deposits in lubricating oil. The temperature in the cylind...
