Problems solved by technology

Frequent replacement of engine oil will not only increase the cost of the engine, but also affect the normal use of the engine. If the replacement is not timely, it will more easily increase the wear and tear of the engine and shorten the service life of the engine.

Embodiment 1

[0037] Energy-saving engine anti-wear agent raw materials (parts by weight): 7 parts of tungsten amino diisopropyl dithiophosphate, 7.5 parts of oleic acid diethanolamide borate, 2.5 parts of oleic acid modified nano-calcium borate, monoenyl butyl 20 parts of imide, 15 parts of polymethacrylate, 7 parts of organic molybdenum, 30 parts of base oil.

[0038] The base oil is stirred with trinonyl trimellitate, tri(2-ethylhexyl) 1,2,4-benzenetricarboxylate, and diisopropyl sebacate in a mass ratio of 1:1:1 Mix well to get.

[0039] The organic molybdenum is obtained by uniformly stirring and mixing 50 wt% molybdenum N,N-diisooctyl dithiocarbamate and 50 wt% molybdenum N,N-di(2-ethylhexyl)dithiocarbamate.

[0040] The preparation method of energy-saving engine anti-wear agent:

[0041] Add polymethacrylate and base oil into the blending kettle, stir and heat to 65°C, keep the temperature at 65°C, add monoalkenyl succinimide, organic molybdenum, aminodiisopropyltungsten dithiophos...

Embodiment 2

[0043] It is basically the same as Example 1, except that the base oil is composed of trinonyl trimellitate and tri(2-ethylhexyl) 1,2,4-benzenetricarboxylate in a mass ratio of 1:1 Stir to mix well. Obtain the energy-saving engine antiwear agent of embodiment 2.

Embodiment 3

[0045] It is basically the same as Example 1, the only difference is that the base oil is composed of 1,2,4-benzenetricarboxylic acid tri(2-ethylhexyl) ester and sebacate diisopropyl ester in a mass ratio of 1:1 Stir to mix well. Obtain the energy-saving engine antiwear agent of embodiment 3.

Abstract

The invention discloses an antiwear agent for an energy-saving engine and a preparation method for the antiwear agent. The antiwear agent comprises the following raw materials in parts by weight: 6-9 parts of tungsten aminodiisopropyl dithiophosphate, 6-9 parts of diglycolamide oleate borate, 0.5-4.5 parts of modified nano-calcium borate, 15-25 parts of monoallyl succinimide, 12-18 parts of polymethacrylate, 6-9 parts of organic molybdenum and 20-40 parts of base oil. The antiwear agent for the energy-saving engine is simple in preparation method, can be widely applied to engines of overloaded heavy vehicles and old vehicles, achieves a very good antiwear repair effect for metal surfaces of slightly worn parts in the engines, and has excellent antiwear and antifriction properties, oxidation resistance, cleanliness and seal property; and the exhaust gas emission is reduced, the fuel consumption is reduced, the resources are saved, and the environmental protection requirements are met.

Description

technical field [0001] The invention relates to the technical field of engine lubricating oil, in particular to an energy-saving engine antiwear agent and a preparation method thereof. Background technique [0002] When the engine is running at high speed, high pressure, and high temperature, the interaction of various friction pairs is likely to produce severe friction. Long-term friction will cause the interface of the friction pair to wear, thereby reducing work efficiency and increasing maintenance costs. At present, lubricating oils for internal combustion engines on the market are all ordinary engine oils, and their high shear properties are particularly easy to decrease under high temperature, high pressure, and high friction conditions, resulting in a decrease in lubricating performance. In order to maintain normal lubrication performance, the oil must be replaced after the vehicle has traveled about 5,000 kilometers. Frequent replacement of engine oil will not only...
