Description
Technical Field
The invention relates to the field of cleaning oil, in particular to novel antiwear environment-friendly engine cleaning oil and a preparation method thereof.
Background
During the running process of the engine, the lubricating oil generates oil sludge, colloid, carbon deposition and the like due to high temperature and metal catalytic oxidation, and along with the extension of the driving mileage, the carbon deposition, the colloid, the oil sludge and harmful substances accumulated in large quantity can aggravate the abrasion of the engine and reduce the service life of the engine. Engine cleaning oil can be adopted to maintain the engine at present, and two times of cleaning in one year or one time of cleaning in twenty thousand kilometers is recommended. According to the statistical data of Ministry of public Security, the number of motor vehicles in China is up to 3.6 million by 6 months in 2020, wherein 2.7 million vehicles are used, and if the engine is cleaned once per vehicle every year, the annual demand of engine cleaning oil is 94.5 million tons. However, the existing engine cleaning oil is mineral engine oil, has poor degradability and causes great pollution when being discharged to the environment.
The prior art (CN100449037C) discloses a novel engine cleaning oil which is composed of one or more of common engine oil 150SN, 500SN, 650SN and 150BS as base oil, Korean high-grade engine oil SK70N, SK150N and SK100N, preservative, antioxidant, antiwear agent, detergent dispersant, pour point depressant and optional defoaming agent, and the physicochemical index reaches the standard of engine oil.
The prior art (CN105733774B) discloses a novel engine cleaning oil and a preparation method thereof, which comprises the following components in percentage by weight: 78.6 to 80.6 percent of base oil, 8 to 9 percent of complexing agent, 0.5 to 1 percent of oxidation and corrosion inhibitor, 0.5 to 1 percent of extreme pressure antiwear agent, 1 to 1.6 percent of pour point depressant, 0.2 to 0.6 percent of antifoaming agent, 3 to 4 percent of dispersant and 4 to 5 percent of detergent. The base oil according to claim 2 or 3 is 150N, 600N or 150 BS.
The essence of the above two patents is a mineral engine oil, and the base oil adopted is a mineral base oil, which is derived from petroleum and is difficult to degrade when discharged into the environment, thereby causing damage to the environment. Detergents and dispersants are used in large quantities in cleaning oil, and the additives also cause great burden on the environment and are not beneficial to environmental protection. Further, the engine oil uses zinc dialkyldithiophosphate (ZnDTP) as an antiwear agent, in which zinc is a metal element. The existing detergents and antiwear agents contain metal elements, and excessive metal elements can generate a large amount of ash, so that a particle catcher of an exhaust gas after-treatment system is blocked. In view of environmental protection and vehicle adaptability, an engine washing oil which does not contain a detergent, a dispersant and a metal element, is environment-friendly and has strong engine protection is urgently needed.
Therefore, it is a significant task to develop a novel biodegradable, vehicle compatible wash oil that is excellent in engine protection.
