New Metallic Detergents for Lubricating Oils

Abstract:

To improve anti-oxidation, anti-wear and extreme-pressure performances of metallic detergents, the over-based substrates of two detergents were modified by partial neutralization with sulfur and phosphor containing carboxylic acids. In this way, two modified detergents were prepared. The non-modified and modified detergents were evaluated by four-ball tester and thermogravimetric analyzer. The results have shown that the modification enhances anti-oxidation and extreme-pressure performance of the detergents without affecting their dispersing ability and anti-wear behavior obviously.
