metal detergent

embodiments of the present disclosure two metal detergents. Detergents generally include a polar head with a long hydrophobic tail, wherein the polar head comprises a metal salt of an acidic organic compound. The salts can a substantially stoichiometric In this case, they usually contain the amount of metal are described as normal or neutral salts, and are typically a measure for the Alkaline content or TBN (measured according to ASTM D2896) from about 0 to lower than about 150. Large amounts of a metal base can pass through Converting a surplus a metal compound such as an oxide or hydroxide with a acidic gas such as carbon dioxide are absorbed. The resulting overbased Detergent comprises micelles of neutralized detergent which surrounded by a core of inorganic metal base (eg hydrated Carbonates). Such overbased Detergents can a TBN of about 150 or higher, such as about 150 to about 450 or higher exhibit.

Zinc sulfonates which are suitable for use in the present invention include zinc dihydrocarbyl aromatic sulfonates such as zinc dialkylnaphthalenesulfonate. The zinc dialkylnaphthalenesulfonate has a sulfonate group attached to a ring of the naphthalene nucleus, and an alkyl group attached to each ring. Each alkyl group may independently contain about six to about twelve carbon atoms, but it is preferred that they contain about eight to twelve carbon atoms. The dialkylnaphthalenesulfonate moiety is attached to the zinc by the sulfonate group. A particularly preferred Zinkdialkylnaphthalinsulfonat is Zinkdinonylnaphthalinsulfonat, which is commercially available as NA-SUL ^® ZS from King Industries, Inc., or alternatively mixtures of Zinksulfonaten and zinc carboxylates in a ratio of zinc sulfonate to zinc carboxylate of about 1: 3 to about 3: 1 parts by weight. Such mixtures are commercially available from King Industries, Inc. under the trade name NA-SUL ZS-HT ^®.

Phosphorus-based wear prevention agent

The Abrasion preventive agent Phosphorus based can be a Metalldihydrocarbyldithiophosphatverbindung include, for example, but not limited to a zinc dihydrocarbyl dithiophosphate compound. Suitable metal dihydrocarbyl dithiophosphates can Dihydrocarbyldithiophosphatmetallsalze include, wherein the metal an alkali or alkaline earth metal or aluminum, lead, tin, molybdenum, manganese, Nickel, copper or zinc can be. The zinc salts are usually used in oil used.

Dihydrocarbyl dithiophosphate metal salts can be prepared by known techniques by first forming a dihydrocarbyl dithiophosphoric acid (DDPA), usually by reacting one or more alcohols or a phenol with P ₂ S ₅ , and then neutralizing the formed DDPA with a metal compound. For example, a dithiophosphoric acid can be prepared by reacting mixtures of primary and secondary alcohols. Alternatively, multiple dithiophosphoric acids can be prepared with the hydrocarbyl radicals being of one completely secondary character and the hydrocarbyl radicals on the other being of completely primary character. Any basic or neutral metal compound may be used to prepare the metal salt, but the oxides, hydroxides and carbonates are most commonly used. Commercial additives often contain an excess of metal due to the use of an excess of the basic metal compound in the neutralization reaction.

Radicals R and R 'may be alkyl radicals having 2 to 8 carbon atoms. Thus, the radicals may be, for example, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, sec-butyl, amyl, n-hexyl, i-hexyl, n-octyl, decyl, dodecyl, octadecyl, 2- Ethylhexyl, phenyl, butylphenyl, cyclohexyl, methylcyclopentyl, propenyl, butenyl. In order to obtain oil solubility, the total number of carbon atoms (ie R and R ') in the dithiophosphoric acid will generally be about 5 or higher. The zinc dihydrocarbyl dithiophosphate may therefore comprise zinc dialkyl dithiophosphates.

Other suitable components used as the phosphorus-based wear preventing agent can be shut down any suitable organophosphorus compound such as but not limited phosphates, thiophosphates, phosphites and salts thereof and phosphonates.

EXAMPLES

These Invention will be more detailed by way of the invention and comparative examples described. The invention should not be limited by these examples; rather, they will serve to enhance the usefulness of the invention demonstrate. The test used to distinguish the FDPT lubricant compositions of the invention from commercially available TO-4 lubricants is the FZG scuffing test method, a wear test which will be described in more detail below.

FZG scuffing

The FZG scuffing test method is used to evaluate the Fresragagfähigkeit of CAT TO-4 fluids used. The test procedure is ASTM D5182, here by Reference, which is a standard method, which is used to evaluate the Fresragagfähigkeit of fluids. The test method evaluates gear tooth surface scuffing resistance fluids using "A" profile gears Attachment will run at 1450 rpm through up to 12 progressive load stages operated in 15-minute intervals. Standard tests are allowed at a fluid temperature of 90 ° C to run. The test procedure starts with a comparatively small one Preload of the mesh gears and after a test period of 15 minutes, the gear teeth will open Eating wear examined. When it is determined that the gear teeth have a predetermined one Have the extent of scuffing, if the test is considered a failure at this stage, and the test is aborted at this point. If the gear teeth are not the predetermined amount Have scuffing, will be an extra Load on the mesh teeth given, and you leave run the test for another 15 minutes. This way of working will continue until it is determined that one of the gear teeth at a particular load stage has failed or stage 12 is reached without failure. It There are no carrying levels Stage 12, therefore the test is canceled after stage 12, assuming that a fluid has acceptable performance. additionally For a visual evaluation of the gear tooth condition, the gear weight loss becomes measured.

For a fluid to meet the requirements of CAT TO-4, performance in the ASTM D5182 FZG Fretting Wear Test must meet the minimum required for performance standards as follows: SAE viscosity range Minimum of completed carrying levels 10W 8th 30W 8th 40W 10 50W 10

statement the test results of inventive and comparative examples

The The present invention is a unique combination of additives for use as a high performance gear oil. This combination presents high friction coefficient, excellent oxidation stability, corrosion protection and a high level Anti-wear performance ready. As shown in Table 1 below, the composition of the present invention is CAT TO 4 compliant while she is also an extraordinary FZG scuffing classification of 12 provides. Comparative FDPT 1 fluid is not CAT TO 4 compliant since it is unable to provide a suitable level of static and sliding friction, as for CAT TO-4 required. Without being tied to a specific theory, it becomes assumed that the absence of zinc sulfonate leads to the FDPT 1 fluid insufficient in the necessary friction performance is to the CAT TO-4 specification to fulfill. The comparative FDPT 2 fluid is a commercially available one CAT TO-4 fluid. Although the FDPT 2-fluid CAT is TO-4 compliant, FIG it is essentially a worse performance than the fluid according to the invention based on the wear and corrosion / oxidation performance, as by the lower one FZG scuffing support levels Classification shown by 8.
