Embodiment 1

[0039] Preparation of carbon remover (the same below):

[0040] Prepare the mixed salt solution of Mg and Al according to a certain ratio, Mg 2+ 、Al 3+ The total concentration of ions is 1.5mol / L, Mg 2+ and Al 3+ The molar ratio is 1.5~4:1.

[0041] Mixed alkali solution of sodium carbonate and sodium hydroxide prepared at room temperature, (CO 3 2- ): (OH - ) in a molar ratio of 1:2.

[0042] The mixed salt solution and the mixed alkali solution were dropped into containers containing deionized water at a temperature of 65°C, while vigorously stirring to keep the pH value at 10. After the drops were completed, the resulting slurry was aged at 65°C for half an hour, and then Suction filtration, beating and washing the filter cake for half an hour, and then suction filtration, repeated several times, and finally put the filter cake in an oven to evaporate overnight at 120 ° C, and put the evaporated filter cake in a muffle furnace at 600 It is calcined at a temperature ...

Embodiment 2

[0048] First, pump 74KG of mineral-type liquid lubricating oil after dehydration pretreatment into the homogeneous kettle at one time, then add 5KG of succinimide dispersant into the kettle after metering, then start stirring and heat up to 60°C , and then 8KG of molybdenum disulfide powder with a particle size of 60 microns, 5KG of Al with a particle size of 60 microns 2 o 3 , 3KG MgO with a particle size of 60 microns, 2KG decarburizer, add to the kettle several times, start to shear and disperse after adding, and control the temperature between 60°C and 70°C. At this time, circulating cooling can be used Adjust the temperature with water, and after two hours, add 3KG of anti-wear agent molybdenum dialkyldithiophosphate into the kettle after metering, continue shearing and dispersing for two hours, then take a sample to test the particle size distribution, and stop shearing if it is qualified. Cut and disperse, then circulate the sand mill for four hours, continue to contro...

Embodiment 3

[0050] First, pump 72KG of mineral-type liquid lubricating oil after dehydration pretreatment into the homogeneous kettle at one time, then add 4KG of succinimide dispersant into the kettle after metering, then start stirring and heat up to 60°C , and then 7KG of molybdenum disulfide powder with a particle size of 50 microns and 7KG of Al with a particle size of 50 microns 2 o 3 , 4KG MgO with a particle size of 50 microns, 2KG carbon remover, add to the kettle several times, start shear dispersion after adding, and control the temperature between 60°C and 70°C, at this time, circulation cooling can be used Adjust the temperature with water, and after two hours, add 4KG of anti-wear agent molybdenum dialkyl dithiophosphate into the kettle after metering, continue to shear and disperse for two hours, then take a sample to test the particle size distribution, and stop shearing if it is qualified. Cut and disperse, then circulate the sand mill for four hours, continue to control...

Abstract

The invention relates to an environment-friendly and energy-saving lubricating oil for effectively removing the carbon deposition, which belongs to the technical field of lubricant. The invention is characterized in that the environment-friendly and energy-saving lubricating oil is made of the raw material with the weight proportions as follows: 5% to 8% molybdenum disulfide fine powder with the particle diameter of 1 to 80 micrometers, 5% to 8% Al2O3 with the particle diameter of 1 to 80 micrometers, 3% to 5% MgO with the particle diameter of 1 to 80 micrometers, 3% to 5% antiwear agent of oxymolybdenum dialkyldithiophosphate, 3% to 5% dispersant of succinimide, 1% to 2% decarbonizer and balance of liquid lubricating material. The product of the invention has the advantages that: firstly, furthest removing of carbon deposition is realized; secondly, the product has the characteristics of super lubrication, wear reduction, extreme pressure resistance and high temperature resistance; thirdly, service life of lubricating components of mechanical equipments is prolonged by more than one time; fourthly, fuel is saved by 15% to 25%.

Description

technical field [0001] The invention belongs to the technical field of lubricants, in particular to an environment-friendly and energy-saving lubricating oil for effectively removing carbon deposits. technical background [0002] At present, the commonly used lubricants mainly have many deficiencies and imperfections in the following technical aspects: blanks for the composite use of various solid materials and poor instant dissolving effect between products and various lubricating oils, slow effect during use, and stable solid-liquid suspension Persistence, high manufacturing costs, uneconomical use, etc. [0003] Diesel engines and gasoline engines use a large amount of lubricating oil. Due to incomplete combustion, carbon deposits are the main reason affecting their lubricating effects. If carbon deposition can be effectively eliminated, its lubricating performance can be improved. Contents of the invention [0004] The purpose of the present invention is to provide a...
