The main function of high temperature antioxidant in lubricating oil is to prevent lubricating oil from oxidizing and deteriorating in high-temperature environment, thereby protecting the normal operation of the engine.
High-temperature antioxidant work through a variety of mechanisms, mainly including:
.Inhibiting the oxidation reaction of lubricating oil: Antioxidant components can effectively inhibit the oxidation reaction of lubricating oil at high temperatures, by reacting with free radicals in the lubricating oil, interrupting the free radical chain reaction, slowing down or stopping the oxidation process of lubricating oil, thereby maintaining its good lubrication performance
.Improving the thermal stability of lubricating oil: By improving the thermal stability of lubricating oil, it can still maintain good performance in high-temperature environments and reduce the occurrence of adverse reactions such as decomposition and polymerization.
.Forming a protective film: Forming a protective film on the metal surface inside the engine to reduce friction and wear, while isolating the metal surface from direct contact with oxygen in the air, reducing the oxidation reaction of lubricating oil due to contact with oxygen at high temperatures.
.Cleaning and dispersing effects: Antioxidants with cleaning and dispersing effects can remove impurities such as sludge and carbon deposits accumulated inside the engine, preventing these impurities from causing oxidation and deterioration of lubricating oil at high temperatures.
.Synergistic effect: Antioxidants work together with detergents, dispersants and other ingredients to prevent lubricants from oxidizing and deteriorating at high temperatures, providing more comprehensive protection1.
In summary, the important role of
High Temperature Antioxidant in lubricants is to ensure that the lubricant maintains its performance and stability in high-temperature environments, thereby protecting the engine from damage and extending its service life
