Non-aromatic based antioxidants for lubricants |
| 摘要 |
A lubricant composition comprises a cycloaliphatic amine alkoxylate and a base oil selected from (a) a polyalkylene glycol; (b) a polyalphaolefin; (c) a naphthenic compound; and (d) combinations thereof; provided that the cycloaliphatic amine alkoxylate and the base oil are miscible. The lubricant may exhibit a viscosity change at 40° C. of less than 5 percent (%) after 13 days at 120° C. in dry air, indicating significant thermoxidative stability with minimal or no aromatic content, thereby enabling use of Groups II and III base oils, in particular, without reduced toxicity and/or quality concerns as compared with Group I base oil lubricants. |

1. A lubricant composition comprising a cycloaliphatic amine alkoxylate and a base oil selected from (a) a polyalkylene glycol; (b) a polyalphaolefin; (c) a naphthenic compound; and (d) combinations thereof; provided that the cycloaliphatic amine alkoxylate and the base oil are miscible,
and wherein the cycloaliphatic amine alkoxylate is selected from the group consisting of 1,2-cyclohexane diamine propoxylate having a propylene oxide content from 5 to 10 moles per mole of 1,2-cyclohexane diamine; 1,2-cyclohexane diamine butoxylate having a butylene oxide content from 5 to 10 moles per mole of 1.2-cyclohexane diamine; and combinations thereof. |
