Problems solved by technology

As a result, higher ash limits are proposed in lubricant specifications
Reducing or limiting the use of such ash-generating metallic lubricant detergents can reduce particulate matter emissions, however this reduces the detergency of these additives in lubricants

Embodiment 1

[0034] A lubricating oil composition, including the following components by weight:

[0035]

[0036] Its production method is:

[0037] Step 1, after weighing the raw materials by weight, first mix the different clean dispersants and different ash dispersants, and preheated to 90 degrees Celsius, to obtain a dispersion additive;

[0038] Step 2, heat the proosing agent to 55 degrees Celsius;

[0039] Step three, mix the plurality of antioxidant preservatives uniform, and preheated to 55 degrees Celsius;

[0040] Step 4, mix a variety of tackifiers uniform, and preheated to 135 degrees Celsius;

[0041] Step 5, the base oil is added to the tone and the tank, and after the stirring conditions of 1350 rpm, after heating to 75 degrees Celsius, the preheated tackifier, preheating duisant, preheating clean dispersion additive And preheated antifoleal projection, then stirred at 75 degrees Celsius to dispersion, filtration, dispensing, and

Embodiment 2

[0043] A lubricating oil composition, including the following components by weight:

[0044]

[0045] Its production method is: as in Example 1.

Abstract

The invention relates to a lubricating oil composition and a preparation method thereof, comprising the following components in parts by weight: 75-95 parts of base oil; 5-10 parts of tackifier; 0.1-1 part of pour point depressant; 2-2 parts of cleaning and dispersing agent 7 parts; 0-2 parts of ashless dispersant; 0.5-3 parts of anti-oxidant preservative; the detergent dispersant includes one or both of rosin and glycerin rosin ester. The present invention adopts one or both of rosin and glycerin rosin ester to replace the traditional alkaline earth metal detergent, which has excellent high-temperature detergency, low-temperature dispersibility, and decontamination ability, and the lubricating oil prepared by using the detergent-dispersant has excellent The cleaning and dispersing effect of the engine can avoid the corrosion and corrosive wear caused by the generation of oxides during the use of the engine.

Description

Technical field [0001] The present invention relates to the field of lubricating oil, and more particularly to a lubricating oil composition and a preparation method thereof. Background technique [0002] The engine's lubrication performance is closely related to the safety, environmental protection, and energy saving. With the continuous improvement of engine performance, the requirements for lubrication are increasing and demanding; the engine is prone to oxides during use, resulting in engine corrosion and corrosion Sexual wear, usual practice is to add clean dispersants such as sulfonate such as sulfonate, but alkaline earth metal detergents having alkaline reserves are introduced into lubricating oil, and the oxide of the engine is removed and prevented from depositing. Formation to ensure the normal operation of the engine, and can extend the life of the engine. [0003] However, these an alkaline earth metal detergent is the main source of ash in the lubricating oil. In or...
