The Core for Enhancing the Performance of Lubricating Oil - Lubricating Oil Antioxidant
Lubricating oil antioxidants are a type of additive that can inhibit the oxidation of oil products and delay the deterioration of their performance. It effectively slows down the aging process of oil products by capturing free radicals, decomposing peroxides and other means, cutting off the oxidation chain reaction.
The role of antioxidants in lubricating oil
Inhibiting oxidation reactions: Antioxidants block or slow down the progress of oxidation chain reactions by capturing free radicals and decomposing peroxides, thus avoiding the generation of harmful substances such as acids, resins, sludge, and paint films due to oxidation.
Extend the oil change cycle: Antioxidants can help lubricating oil maintain stable performance under high-temperature or long-term usage conditions and slow down the rate of deterioration. For engine oil, turbine oil, hydraulic oil, gear oil and other oil products that need to operate for a long time, they are particularly crucial.
Protecting metal parts: Acidic substances in oxidation products can corrode the metal surface and accelerate wear. Antioxidants reduce the formation of acids, thereby lowering the risk of corrosion for components such as bearings, gears, and valves.
Enhance adaptability to high-temperature working conditions: At high temperatures, the oxidation rate of oil products will increase exponentially. Aromatic amine high-temperature lubricating oil antioxidants can still effectively inhibit oxidation under high-temperature conditions and are often used in gas turbine oil, compressor oil, etc.
Synergistic effect, enhancing the overall formula performance: Antioxidants often work in synergy with detergents, dispersants, preservatives, anti-wear agents, etc., to form a complete protective system. Common combination: Hindered phenols + aromatic amines → balancing initial and long-term antioxidant performance; Phenols + phosphite esters → Simultaneously inhibit oxidation and metal catalysis.
