Abstract
The present invention relates to a multifunctional lubricant composition which serves as a base oil for lubrication or as an additive for lubrication, including, with respect to 100 parts by mass of phosphorus compound (A) having a specific structure specified in the Description, 26 parts by mass to 43 parts by mass of phosphorus compound (B) having a specific structure specified in the Description, 0 parts by mass to 1.3 parts by mass of phosphorus compound (C) having a specific structure specified in the Description, and a total of 0 parts by mass to 1.3 parts by mass of triphenyl phosphate and tricresyl phosphate.
Claims5
A lubricating oil composition comprising a base oil for lubrication and an additive for lubrication,
- wherein the additive for lubrication comprises, with respect to 100 parts by mass of phosphorus compound (A) represented by the following formula (1), 26 parts by mass to 43 parts by mass of phosphorus compound (B) represented by the following formula (2), 0 parts by mass to 1.3 parts by mass of phosphorus compound (C) represented by the following formula (3), and a total of 0 parts by mass to 1.3 parts by mass of triphenyl phosphate and tricresyl phosphate,
- wherein the lubricating oil composition comprises 0.01 part by mass to 6 parts by mass of the additive for lubrication with respect to 100 parts by mass of the base oil for lubrication, and
- wherein the additive for lubrication is a different oil from the base oil for lubrication:
- wherein R1 represents a hydrocarbon group having 1 to 10 carbon atoms, R2 represents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, and R3 and R4 each independently represent a hydrogen atom or a methyl group, provided that when R1 represents a methyl group, R2 does not represent a hydrogen atom;
- wherein R5 and R7 each independently represent a hydrocarbon group having 1 to 10 carbon atoms, R6 and R8 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, and R9 represents a hydrogen atom or a methyl group, provided that when R5 represents a methyl group, R6 does not represent a hydrogen atom, and that when R7 represents a methyl group, R8 does not represent a hydrogen atom;
- wherein R10, R12, and R14 each independently represent a hydrocarbon group having 1 to 10 carbon atoms, and R11, R13, and R15 each independently represent a hydrogen atom or a methyl group, provided that when R10 represents a methyl group, R11 does not represent a hydrogen atom, that when R12 represents a methyl group, R13 does not represent a hydrogen atom, and that when R14 represents a methyl group, R15 does not represent a hydrogen atom.
A method for enhancing abrasion resistance in a base oil for lubrication, comprising adding an additive for lubrication to the lubricant base oil,
- wherein the additive for lubrication comprises, with respect to 100 parts by mass of phosphorus compound (A) represented by the following formula (1), 26 parts by mass to 43 parts by mass of phosphorus compound (B) represented by the following formula (2), 0 parts by mass to 1.3 parts by mass of phosphorus compound (C) represented by the following formula (3), and a total of 0 parts by mass to 1.3 parts by mass of triphenyl phosphate and tricresyl phosphate,
- wherein the lubricating oil composition comprises 0.01 part by mass to 6 parts by mass of the additive for lubrication with respect to 100 parts by mass of the base oil for lubrication, and
- wherein the additive for lubrication is a different oil from the base oil for the lubrication:
- wherein R1 represents a hydrocarbon group having 1 to 10 carbon atoms, R2 represents a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, and R3 and R4 each independently represent a hydrogen atom or a methyl group, provided that when R1 represents a methyl group, R2 does not represent a hydrogen atom;
- wherein R5 and R7 each independently represent a hydrocarbon group having 1 to 10 carbon atoms, R6 and R8 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, and R9 represents a hydrogen atom or a methyl group, provided that when R5 represents a methyl group, R6 does not represent a hydrogen atom, and that when R7 represents a methyl group, R8 does not represent a hydrogen atom;
- wherein R10, R12, and R14 each independently represent a hydrocarbon group having 1 to 10 carbon atoms, and R11, R13, and R15 each independently represent a hydrogen atom or a methyl group, provided that when R10 represents a methyl group, R11 does not represent a hydrogen atom, that when R12 represents a methyl group, R13 does not represent a hydrogen atom, and that when R14 represents a methyl group, R15 does not represent a hydrogen atom.
