What is Amine Type Antioxidants？
Amine Type Antioxidants are chemical additives added to lubricating oils (mainly used in internal combustion engines) to prevent oil degradation and the formation of harmful by-products. They play an important role in preventing oil oxidation and the formation of degradation products. Oxidation is an unwanted chemical process that occurs when oil comes into contact with oxygen and heat in the air, resulting in the formation of organic acids, gum and varnish deposits, and other harmful substances that can impair the oil’s performance and cause engine wear.

The functions of amine antioxidants are as follows:
- Inhibits Oxidation: Oxidation occurs when oil is exposed to oxygen and high temperatures, leading to the formation of acidic compounds, sludge and varnish deposits. These oxidation products can reduce oil performance and cause engine or mechanical damage. Amine antioxidants help prevent or slow down this oxidation process. Antioxidant amines react with oxygen free radicals and other reactive compounds that initiate oxidative reactions. By neutralizing these free radicals, amines help prevent or delay oil oxidation, making it more stable and extending the life of the lubricant.
- Acid Neutralization: During the oxidation process, lubricating oil produces organic acids that are corrosive and harmful to engine components. Antioxidant amines also act as acid neutralizers, helping to reduce acid formation and protect the engine from corrosion.
- Prevents Deposits: Amine antioxidants prevent the formation of deposits, including sludge and varnish, that can accumulate on engine components and interfere with their function. Amine antioxidants prevent these substances from accumulating on the surfaces of engine components such as pistons and valves. By keeping the oil clean, these antioxidants help improve the overall efficiency and performance of your equipment.
- Extended oil life: Amine antioxidants extend the life of lubricants by slowing down the oxidation process. This helps reduce the frequency of oil changes and maintenance intervals, saving equipment owners time and money.
- Corrosion Protection: Amine antioxidants also prevent corrosion on metal surfaces that come into contact with lubricants. Oxidation products can be corrosive, and the presence of antioxidants can help mitigate this corrosion, thereby maintaining the integrity of the machine or engine.
- Maintain Viscosity: Oxidation can cause the oil’s viscosity to change, making it less effective as a lubricant. Amine antioxidants help maintain the oil’s viscosity over the long term, ensuring it continues to provide proper lubrication and protection to moving parts.
- Compatibility: Amine antioxidants are generally designed to be compatible with other additives and base oils commonly used in lubricants. This ensures they can be effectively incorporated into a variety of oil formulations without causing unwanted interactions.
It is worth noting that different types of antioxidants can be used in lubricants depending on the specific requirements of the application and the type of base oil used. While amine antioxidants are effective in many situations, other antioxidants, such as phenolic antioxidants, can be used in combination or as alternatives to address specific challenges in lubrication systems. The choice of antioxidant depends on factors such as operating conditions, type of machinery and desired oil performance characteristics.
