Lubricant Oil Compositions

摘要

Compositions comprise first antioxidants and first additives, such as, a surface additives, performance enhancing additives and lubricant protective additives and optionally second additives and/or second antioxidants. The compositions are useful to improve lubricants, lubricant oils and other lubricant materials. The compositions and methods generally provide longer shelf lives, increased oxidative resistance, improved quality and/or enhanced performance to lubricants or lubricant oils.

1. A lubricant composition, consisting essentially of:
a) a lubricant or a mixture of lubricants; b) an antioxidant component include a first antioxidant represented by the following structural formula: wherein R″ is an optionally substituted alkyl, an optionally substituted aryl or an optionally substituted aralkyl; and c) at least one first additive selected from the group consisting of:
i) a surface additive;ii) a performance enhancing additive; andiii) a lubricant protective additive; wherein the concentration of the first antioxidant is between about 0.05% to about 5% by weight of the lubricant composition and the concentration of the first additive is between about 0.05% and about 5% by weight of the lubricant composition.
