Problems solved by technology

Although different additives can achieve different levels of lubricating effects under different usage conditions, they all have some defects such as clogged oil passages, high toxicity and pollution. What is more serious is that traditional lubricating oils and additives rely on oil films to achieve Lubrication, so once the oil surface does not touch or the contact surface is too thin, such as when the engine is ignited from a cooling state, it often causes instantaneous large friction and wears out the parts

example 1～3

[0024] Examples 1-3 are the ingredients and content of the additives of the present invention, see Table 2 for details. Specific preparation method: Add each ingredient into a blending kettle with a stirrer, stir for one hour, it becomes a clear and transparent viscous liquid, and put it into a storage tank.

example 4

[0026] This example is the friction and wear test of lubricating oil added with 2-15% of the additive of Example 2 of the present invention. The base oil used is 15W / 40SE lubricating oil (Great Wall Advanced Lubricating Oil Company), 150SN (Dalian Petrochemical Company). The results are shown in Table 3 and Table 4. Test conditions for wear scar diameter (mm) in Table 3: 1200 rpm, 75°C, D 60min 15kg (equivalent to ASTM D2783); maximum bite load (kg) test conditions: room temperature (equivalent to ASTM D4172); test conditions for wear scar diameter (mm) in Table 4: 75°C, 1200 rpm, D 60min 15kg , wear scar diameter (mm) test conditions: 75 ℃, 1200 rpm, D 15kg 60min .

[0027] Test conclusion: After the additive of the present invention is added in 150SN neutral oil and 15W / 40SE lubricating oil, wear scar diameter reduces to some extent, and when the addition amount is 5%, improve respectively 47%, 16% and 13%; Improvement, the maximum seizure load can be increased by 42%...

example 5

[0029] This example is SD40 gasoline engine oil (Daqing Petrochemical General Plant) adding the anti-friction performance test of the additive of Example 1 of the present invention.

[0030] 1. Anti-wear performance test

[0031] Testing machine: reciprocating friction wear testing machine

[0032] Sample: GCr15 steel ball and GGr15 steel bar

[0033] Test conditions: load 22 kg, reciprocating frequency 25 times / min, temperature 28°C

[0034] Test results: the extreme value (ratio of load to wear scar area after stabilization) of base oil and 10% additive is 208N / mm respectively 2 、472N / mm 2 , the extreme pressure value increased by 125%

[0035] Conclusion: Adding 10% of the additive of the present invention to SD40 gasoline engine oil can greatly improve the anti-wear performance of lubricating oil.

[0036] 2. Anti-friction performance test

[0037] Testing machine: MPX200 (Yihua Testing Machine Factory)

[0038] Sample: the upper ring is GCr15 steel ring, the lower ...

Abstract

A lubricating oil additive based on the libricating mechanism of cermet is prepared from mineral oil, alkali-earth metal sulfonate, polyboroamine, atoleine, zinc dialkyldithiophosphate, molybdenum dialkyldithiophosphate and arene solvent. It can be converted to chemical-bond ceramic structure of molybdenum phosphate and boron nitride in friction part, resulting in reducing wear and temp of engine, increasing efficiency of fuel oil, and decreasing tail gas exhaust and noise.

Description

technical field [0001] The invention belongs to the technical field of lubricants, more specifically, the invention relates to an additive compatible with all current lubricant products. Background technique [0002] Lubricating oil is called the blood of the machinery industry. Without lubricating oil, there would be no machinery industry. In recent years, with the development of internal combustion engines towards high thermal efficiency, power performance of specific power, economic performance of reducing fuel consumption and performance of reducing pollutant emissions, internal combustion engine oil products have been updated rapidly. However, since the traditional lubrication theory established in the 1930s and 1940s is difficult to break through, the lubrication method still stays at the level of the 1940s and 1950s. Traditional lubricating oils rely on the viscosity of the oil film to achieve the lubricating effect. Usually, appropriate additives such as anti-corros...
