Embodiment Construction

[0025] Get 45.6 parts by weight of molybdenum thiophosphate, 16.8 parts by weight of polyisobutene diimide, 16.4 parts by weight of phosphate ester amine salt, 21.2 parts by weight of SJ machine oil or CF machine oil, join 2 / 3 capacity in the blending kettle; The mixture is fully stirred and blended in the blending kettle at room temperature (electric stirring for 1 hour); the blending kettle is connected to the colloid mill, and the colloid mill is used for grinding and blending synchronously (1 hour) while stirring and blending to ensure that the particles are less than 10 Nano; heat the blending kettle with sealed steam at 90°C-100°C, use the hot pressure of the blending kettle itself to stand still for 2 hours, and then pack it into a finished product.

[0026] The use method of the present invention is to uniformly mix the present invention into the engine oil of an internal combustion engine at a ratio of 0.8% to 2.5%.

Abstract

The present invention is lubricating additive for engine oil in internal combustion engine and its preparation process, and aims at improving the kinetic viscosity and oil film strength of engine oil, reducing friction between the cylinder jacket and piston ring of internal combustion engine, and prolonging the service life of internal combustion engine. The additive consists of mixed molybdenum sulfate phosphate, polyisobutylene diimide, phosphate ester amine, SJ engine oil or CF engine oil in certain proportion. When being used, the additive is mixed into engine oil for internal combustion engine in certain ratio.

Description

(1) Technical field: [0001] The invention relates to an additive for engine oil of an internal combustion engine. (two) background technology: [0002] Cylinder liners and piston rings of internal combustion engines work under conditions of high temperature, high pressure, alternating loads and corrosion, and work under complex and changeable conditions for a long time, resulting in wear and deformation of cylinder liners, which affects the power and economy of internal combustion engines. sex and longevity. [0003] At present, with the rapid growth and popularization of my country's automobile consumption, the diversity of vehicles, the complexity of the region and the use of the environment have been reflected, which has led to a trend of diversification of internal combustion engine oil products. Usually, the internal combustion engine oil we use is due to the brand The different additives are different and the preparation method is different, which leads to the change o...
