Description
Technical Field
The invention belongs to the technical field of application of activated carbon materials and engine oil filtration, and particularly relates to a novel preparation method of a carbon-based forming engine oil purification material for vehicles and ships.

In the running process of the engine, engine oil needs to be continuously conveyed to the surfaces of all parts of the engine to form a lubricating oil film, so that the friction resistance of all parts of the engine in the running process is reduced, the abrasion of the parts is reduced, the temperature of the engine is reduced, the running efficiency of the engine and the utilization efficiency of gasoline are improved, and the stable and efficient running of the engine is further ensured. Along with the continuous operation of the engine, metal abrasive dust, carbon deposit, dust in the air and the like generated in the working process are mixed into the engine oil, so that the impurity content of the engine oil is increased; meanwhile, the engine generates high-temperature and high-pressure environment in the running process, so that the engine oil is oxidized and decomposed to form colloid and other substances, and the quality of the engine oil is reduced. The increase of impurity content and the reduction of quality of the engine oil are not beneficial to the stable operation and working of the engine. Therefore, the oil filter is required to filter oil impurities and improve the quality of the oil, so as to ensure efficient and stable operation of the engine.
The filter element is a main component of the engine oil filter, and is used for filtering impurities such as dust, metal abrasive dust, carbon deposition, colloidal precipitate and the like generated in the working process of an engine, so that the engine oil is kept clean, and the service life of the engine oil is prolonged; meanwhile, the engine oil is cleaned, so that friction in the working process of the engine is reduced, the temperature of the engine is reduced, the phenomena of pre-ignition and deflagration of the engine are prevented, the effective power of the engine is improved, the combustion efficiency of gasoline is improved, the fuel is saved, the consumption is reduced, and the exhaust pollution and the emission are reduced.
The high-quality engine oil filter element needs to have good dirt holding capacity and a purifying effect, and simultaneously needs to have good high temperature resistance and pressure resistance under the conditions of meeting the high-temperature environment of the engine oil and large flux flow rate.

Meanwhile, for the used binder, the binder not only needs to have good oil resistance, high temperature resistance and cementing strength, but also needs to keep good adsorption effect and purification effect without blocking the pore structure of the adsorption material during cementing. At present, when a common activated carbon material is used for purifying engine oil, the surface microstructure of the common activated carbon material is not suitable for adsorbing and removing impurities in an oil phase, and the problems of low purification efficiency, small dirt holding capacity, short service life and the like exist.
