Definitions

  • the performance additive package will be determined by the desired end use application.
  • In general power transmission fluid performance packages contain anti-oxidants, anti-wear agents, friction modifiers, ashless dispersants, extreme pressure agents, corrosion inhibitors, viscosity modifiers and anti-foamants, each present in customary amounts so as to provide their normal attendant functions, such as 1 to 25 wt.%.
  • the exact amounts and presence or absence of the individual components will be determined by the intended application.
  • Automotive Gear Oil ⁇ one type of automotive gear oil additive package would contain one or more of a highly sulfurized hydrocarbon or ester, a phosphite or phosphate, corrosion inhibitors, dispersants and anti-foamants.
  • Infineum T4804 from Infineum, which contains antifoamant, antioxidant, rust inhibitor, magnesium sulfonate detergent, seal swellant, amine phosphate antiwear additive, borated polyisobutenyl succinimide dispersant and friction modifier, each present in customary amounts so as to provide their normal attendant function.
  • Manual transmission fluid additives generally comprise from about 1% to about 10% of the weight of the finished lubricant.
  • Automatic Transmission Fluid ⁇ automatic transmission fluid additive packages normally consist of ashless dispersants; anti-wear agents; anti-oxidants; corrosion inhibitors; friction modifiers; seal swell agents; anti-foamants and sometimes viscosity modifiers. Examples of commercially available automatic transmission fluid additives are: Lubrizol 6950; Lubrizol 7900; Lubrizol 9614 from the Lubrizol Corporation; Hitec 403; Hitec 420; Hitec 427 from the Ethyl Corporation and Infineum T4520, Infineum T4540 from Infineum. Automatic transmission fluid additives normally comprise from about 1 to about 20% of the weight of the finished lubricant.
  • Such groups include the following: (1) hydrocarbon groups; that is, aliphatic, alicyclic (e.g., cycloalkyl or cycloalkenyl), aromatic groups, alkaryl groups, and the like, as well as cyclic groups wherein the ring is completed through another portion of the molecule; (2) substituted hydrocarbon groups; that is, groups containing non-hydrocarbon substituents which in the context of this invention, do not alter the predominantly hydrocarbon nature of the group. Those skilled in the art will be aware of suitable substituents.
  • hetero groups examples include, halo, hydroxy, nitro, cyano, alkoxy, acyl, etc.; (3) hetero groups; that is, groups which while predominantly hydrocarbon in character within the context of this invention, contain atoms of other than carbon in a chain or ring otherwise composed of carbon atoms. Suitable hetero atoms will be apparent to those skilled in the art and include, for example, nitrogen, oxygen and sulfur.
  • Suitable corrosion inhibitors for use in the ATF performance additive packages of this invention include zinc dialkyl dithiophosphate, phosphosulfurized hydrocarbons, thiadiazoles such as 1,3,4-thiadiazoles and C 2 -C 30 hydrocarbyl substituted derivatives thereof, benzotriazole and C 1 -C 8 alkyl substituted benzotriazoles, such as tolyltriazole and hexylbenzotriazole, or their reaction products with monoamines and polyamines.
  • Suitable seal swellants for use in the ATF performance additive packages of this invention include aliphatic alcohols of 8 to 13 carbon atoms, such as tridecyl alcohol; and oil soluble aliphatic or aromatic hydrocarbon esters of 10 to 60 carbon atoms and 2 to 4 linkages, such as dihexyl phthalate, and alkoxyl sulfolane derivatives such as 3-isodecyloxy-sulfolane.
  • Examples A, B, E and F illustrate the static friction reducing additive of the invention.
  • Examples C and D are comparative examples which were evaluated in the table below.
