Definitions
- This disclosure relates to lubricating oil additives and lubricating oil compositions containing the same. More specifically, this disclosure describes zinc- free additives that impart anti-wear properties to lubricating oil compositions.
- Zinc dialkyldithiophosphate has long been used as a wear inhibitor in various lubricating fluids such as automotive engine oil. At least one drawback is that ZnDTP can decompose due to high temperature, oxidative deterioration, or hydrolysis in the presence of water. The result of the decomposition is a sludge that decreases friction coefficient and/or clogs important moving parts.
- a lubricating oil composition comprising: a major amount of an oil of lubricating viscosity having a kinematic viscosity at 100°C in a range of about 1.5 to about 35 mm 2 /s; and an anti-wear mixture comprising: one or more ashless dispersants and an alkyl phosphonic acid having a structure given by wherein R is a C 3 -C 20 hydrocarbyl group; initial pH of the anti-wear mixture is between 5.0-9.5 as measured by ASTM D664; and wherein the lubricating oil composition is free of zinc.
- a lubricating oil composition comprising: a major amount of an oil of lubricating viscosity having a kinematic viscosity at 100°C in a range of about 1.5 to about 35 mm 2 /s; and an anti-wear mixture comprising: one or more polyisobutenyl succinimide dispersants and an alkyl phosphonic acid having a structure given by wherein R is a C 3 -C 20 hydrocarbyl group; initial pH of the anti-wear mixture is between 5.0 - 9.5 as measured by ASTM D664; and wherein the lubricating oil composition is free of zinc.

- Alkenyl or alkyl succinimides are disclosed in numerous references and are well known in the art. Certain fundamental types of succinimides and related materials encompassed by the term of art "succinimide” are taught in U.S. Patent Nos. 2,992,708; 3,018,291; 3,024,237; 3,100,673; 3,219,666; 3,172,892; and 3,272,746.

- hydrocarbyl groups include alkenyl, alkyl, polyalkenyl, polyalkyl, phenyl, and the like.
- 'oil-soluble' or 'oil-dispersible' do not necessarily indicate that the compounds or additives are soluble, dissolvable, miscible or capable of being suspended in the oil in all proportions. These do mean, however, that they are, for instance, soluble or stably dispersible in oil to an extent sufficient to exert their intended effect in the environment in which the oil is employed. Moreover, the additional incorporation of other additives may also permit incorporation of higher levels of a particular additive, if desired.
- a dispersant is an essential lubricant additive, particularly in engine oil and automatic transmission fluid, for preventing sludge generation and increasing friction coefficient of wet clutch.
- dispersants can often reduce the effects of anti-wear agents (e.g., ZnDTP) and extreme pressure (EP) additives particularly in sulfur phosphorus (S-P) type gear oils and automatic transmission fluids.

- the base oil will have a kinematic viscosity at 100°C (ASTM D445) in a range of 1.5 to 35 mm 2 /s (e.g., 1.5 to 25 mm 2 /s, 2.0 to 20 mm 2 /s, or 2.0 to 15 mm 2 /s).
- the present lubricating oil compositions may also contain conventional lubricant additives for imparting auxiliary functions to give a finished lubricating oil composition in which these additives are dispersed or dissolved.
- the lubricating oil compositions can be blended with antioxidants, ashless dispersants, anti-wear agents, detergents such as metal detergents, rust inhibitors, dehazing agents, demulsifying agents, friction modifiers, metal deactivating agents, pour point depressants, viscosity modifiers, antifoaming agents, co-solvents, package compatibilizers, corrosion-inhibitors, dyes, extreme pressure agents and the like and mixtures thereof.
- a variety of the additives are known and commercially available. These additives, or their analogous compounds, can be employed for the preparation of the lubricating oil compositions of the invention by the usual blending procedures.
- each of the foregoing additives when used, is used at a functionally effective amount to impart the desired properties to the lubricant.
- a functionally effective amount of this ashless dispersant would be an amount sufficient to impart the desired dispersancy characteristics to the lubricant.
- the concentration of each of these additives, when used may range, unless otherwise specified, from about 0.001 to about 20 wt. %, such as about 0.01 to about 10 wt. %.
- Lubricating oil samples were evaluated for anti-wear performance. Each sample includes succinimide dispersant, a phosphorus additive (optional in some comparative examples), other lubricating oil additives (friction modifiers, ashless anti-wear additives, antioxidants, metal deactivators, seal swell additives, foam inhibitors, and viscosity modifiers), and base oil.
- Borated Succinimide 1 is a boron-modified polyisobutenyl succinimide with a polyisobutylene number average molecular weight of 950 (N: 1.95 wt%; B: 0.63 wt%).
- Borated Succinimide 2 is a boron-modified polyisobutenyl succinimide with a polyisobutylene number average molecular weight of 1,300 (N: 1.88 wt%; B: 0.36 wt%).
- Succinimide 1 is a polyisobutenyl succinimide with a polyisobutylene number average molecular weight of 950 (N: 2.15 wt%).
- Succinimide 2 is a polyisobutenyl succinimide with a polyisobutylene number average molecular weight of 950 (N: 2.0 wt%).

- the anti-wear performance of each lubricating oil compositions was determined using the 4 ball wear scar test (ASTM D4172) at 1200 rpm and 1800 rpm, oil temperature of 80°C, and load of 392N for 60 min. After testing, the test balls were removed and the wear scars were measured. The wear scar diameters are reported in mm in Table 1 and Table 2. A smaller wear scar diameter indicates better anti-wear performance.
- Comparative examples 1-8 which contain succinimide but do not contain alkyl phosphonic acid showed poor anti-wear performance.
- inventive examples 1-4 which contain succinimide and C 4 -C 18 alkyl phosphonic acids showed superior anti-wear performance.
- the electrical insulating ability of the lubricating oil compositions was determined in accordance with JIS C2101-1999-24.
- the volume resistivity values of several examples were measured at an applied voltage of 250 V and reported in units of ⁇ cm in Table 3.
- a volume resistivity of greater than 1 x 10 8 ⁇ cm at 80°C is preferred for adequate insulating properties in transmission fluids.
- ranges from any lower limit may be combined with any upper limit to recite a range not explicitly recited, as well as, ranges from any lower limit may be combined with any other lower limit to recite a range not explicitly recited, in the same way, ranges from any upper limit may be combined with any other upper limit to recite a range not explicitly recited.
- ranges from any upper limit may be combined with any other upper limit to recite a range not explicitly recited.
- within a range includes every point or individual value between its end points even though not explicitly recited. Thus, every point or individual value may serve as its own lower or upper limit combined with any other point or individual value or any other lower or upper limit, to recite a range not explicitly recited.
- compositions, an element or a group of elements are preceded with the transitional phrase “comprising,” it is understood that we also contemplate the same composition or group of elements with transitional phrases “consisting essentially of,” “consisting of,” “selected from the group of consisting of,” or “is” preceding the recitation of the composition, element, or elements and vice versa.
