amine type antioxidant additives in lubricants

Description

Amine Antioxidants: These additives contain amine-based compounds that act as free radical scavengers to inhibit oxidation.

Examples of amine antioxidants include alkylated diphenylamine (ADPA) and alkylated naphthylamine (ANA). These additives are often combined with other antioxidants to enhance performance.

They are particularly effective in preventing oxidation in high temperature applications and preventing thermal degradation. They can be divided into primary and secondary amines.

Examples of amine antioxidants include hindered amine light stabilizers (HALS) such as bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate (Tinuvin 770) and 4-hydroxy-2 ,2,6,6-Tetramethylpiperidine-N-oxyl (Tempo).

It is important to note that the selection and combination of antioxidant additives in lubricant formulations depends on factors such as application, base oil type, operating conditions and desired performance requirements. Therefore, the specific antioxidant additive used can vary depending on the application and desired performance characteristics.

The selection of antioxidant additives depends on factors such as the type of lubricant, operating conditions and desired performance characteristics. Different types of antioxidants can be combined in lubricant formulations to achieve optimal antioxidant protection.
