Abstract

The invention discloses a castor-based high alkali value synthetic magnesium sulfonate composite lithium-based lubricating grease composition, which adopts HVIW650 base oil and castor-based diisodecyl sebacate as the base oil, and cooperates with various composite additives , which includes: soap-making component 1, soap-making component 2, soap-making component 3, soap-making component 4, rust inhibitor, antioxidant, viscosity index improver and detergent. The composition of the present invention has high temperature resistance, can withstand heavy loads, antirust, multi-effect environment-friendly grease, does not contain heavy metals and additives harmful to the environment, good high temperature performance, mechanical stability, water resistance, salt rust resistance , rust and corrosion resistance and excellent extreme pressure and wear resistance.

Description

technical field [0001] The invention belongs to the field of lubricating grease, and in particular relates to a castor-based high alkali value synthetic magnesium sulfonate composite lithium-based lubricating grease composition. Background technique [0002] Although the high alkali value calcium sulfonate used as a detergent and antirust agent for engine oil has been found to be used as a thickener in lubricating greases, it has not been popularized and applied until the 1980s, when people prepared The high-basic calcium sulfonate complex calcium-based lubricating grease can only reflect its excellent performance. However, the synthesis of magnesium sulfonate with high base value to prepare lithium complex grease needs further research, including grease structure, fat-forming mechanism, rheology, salt spray resistance, extreme pressure and anti-wear properties, water resistance, and colloidal stability. , oxidation stability, hardening and oil separation during storage, an...
