examples

[0122]Without being limited, in the below examples, exemplary lubricant compositions were formulated by blending each of the components together until homogeneity was achieved. A fully formulated lubricating oil composition containing dispersant, detergent, aminic antioxidant, phenolic antioxidant, anti-foam, base oil, antiwear additive, pour point depressant and viscosity modifier was prepared. This lubricant composition, which is representative of a commercial crankcase lubricant, is designated as the “reference lubricant” and used as a baseline to compare the effects of different components on seal compatibility.

[0123]The reference lubricant was combined with various different boron-containing compounds and various different nitrogen-containing compounds to demonstrate the effect of the boron-containing compounds and the effect of nitrogen-containing compounds on seal compatibility. Practical Examples #1 and #2 each include one of the practical boroxine compounds and one of the p...

Abstract

A lubricant composition including a boroxine compound is disclosed. An additive package including the boroxine compound is also disclosed. The lubricant composition and the additive package may additionally include an amine compound. The boroxine compound of the lubricant composition acts to improve compatibility of the lubricant composition with a fluoropolymer seal.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 713,088 filed on Oct. 12, 2012 and U.S. Provisional Patent Application No. 61 / 713,103 filed on Oct. 12, 2012, each of which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention generally relates to a lubricant composition that includes a base oil, a boroxine compound, and an amine compound. The invention also relates to an additive package for a lubricant composition.BACKGROUND OF THE INVENTION[0003]It is known and customary to add stabilizers to lubricant compositions based on mineral or synthetic oils in order to improve their performance characteristics. Some conventional amine compounds are effective stabilizers for lubricants. These conventional amine compounds may help neutralize acids formed during the combustion process. However, these conventional amine compounds are generally not employed in combustion engines due to thei...
