Definitions
- This invention relates to improved gear oils comprising a blend of two selected petroleum stocks as the base for the "extreme pressure gear oil additive mixture of the present invention, which functions synergistically.
- gear oils containing this additive mixture have been used successfully for years in commercial applications such as steel mills, power generating plants,
- an oil blend consisting of a mixture of 55-85% of a particular high viscosity index bright stock fraction and 45-15% of a high viscosity index mineral lubricating oil, both fractions having both fractions being rich in aromatics, function not only naphthenate and a sulfurized fatty oil or derivative therea viscosity index of at least 80, prefer-ably 90-140 and I of such as sulfurized sperm oil, but the base oil blend acts synergistically to activate the extreme pressure life .of gear oil additive mixture so that it is increased many fold, namely from 1 to 10 times that of commercial gear oils containing lead naphthenate and sulfurized fatty products, and inhibits additive depletion and oxidation of the composition.
- the manner in which the oil blend of the present invention functions in the manner described is not understood, except for the fact thatin order to produce the desired results, the base oil blend must be carefully selected and blended in specific proportions, each fraction of which must possess the following properties:
- the bright stock fraction must be rich in aromatics (570%) and have a viscosity index of at least 80, preferably between 90 and 110 and is obtained during the refining of mineral oils from the short residue after the distillate fractions have been removed.
- the short residue is dewaxed and deasphalted and if desired solvent and clay-treated.
- the raffinate which remains after this treat- -ment is called bright stock.
- the brightstocks should have the following range of properties:
- . 9. may vary up to 30%, or more.
- the other portion of the oil blend is a high viscosity index lubricating oil distillate fraction and specifically is a refined distillate fraction having a viscosity index of at least 90, preferably 90-110, an SUS viscosity at F.
- Viscosity index 90-95 Analysis (incremental ultraviolet absorption):
- Base blends which are particularly preferred are:
- the additive combination which is synergistically activated, stabilized and its depletion inhibited by the base blend described comprises of a mixture of 1-10% (preferably 2-5%) lead naphthenate and 110% (preferably 3- 6%) by weight of sulfurized long chain fatty oil product such as sulfurized sperm oil.
- the lead naphthenate utilized in the'lubricant can be prepared from naphthenic acids obtained in the refining of petroleum, particularly the naphthenic acids derived from lubricating oil fractions. Moreover, the naphthenic acids can contain some non-saponifiable mineral oil which prepared from lubricating oil naphthenic acids having a non-sflponifiable content of about 23%, has a PhD content of roughly about 20% by weight. Lead naphthenate prepared from naphthenic acids essentially freed from non saponicfi-able content will run about 30% PhD content.
- the sulfurized fatty material containing -40% sulfur in the molecule can be sulfurized sperm oil (30% S).
- a sulfurized sperm oil of this type is available from Carlisle Chemical Works as Base 100-8 or 120-S, the latter of which has the following properties:
- a minor amount (15% by weight) of a secondary additive can phenol; bisphenols, e.g. 4,4'-rnethylene (2,6-ditertbutyl phenol), 4,4'-thio bis (2,6-ditertbutyl phenol); arylamines such as phenyl-alpha-naphthylamine or phenyl-beta-naph- I thylamine.
- Base blend (C): V 5 65% Bright stock (40% aromatics) HVI mineral lubricating oil (VI 90, Aromatics 35 +4% lead naphthenate +4% sulfurized sperm oil (V) Base blend (13):
- Tests Oxidation Tests 300 F. Bench Oxidation Test (B0 Test).In this method 300 ml. of test oil are oxidized in a cylindrical Pyrex glass cell at 300 F. with 5 liters air perhour for 168 hours. No catalyst is used. The relative oxidation resistance of an oil is evaluated by viscosity increase and sludge formation during the test.
- Oxidation Test Modified Turbine Oil Stability Test.This test is a modification of ASTM Method D- 943, Oxidation Characteristics of Inhibited Steam Turbine Oils. In modifying ASTM D-943 for assessing the oxidation characteristics of Macoma blends, the test temperature is increased from 205 F. to 250 F., air instead of oxygen is used, water is omitted, and oil test. life con- 4 stitutes' the number of hours of oxidation required to double the original S.S.U. viscosity at 210 F.
- compositions of the present invention can be used as extreme pressure lubricants for various heavy duty equipments operating under severe and adverse conditions of temperature and pressure.
- An improved gear oil composition consisting essentially of a mixture of two mineral oil fractions of: (1) 5585% of a 90140 VI Bright Stock having an aromatic content of at least 5% and (2) 15% of a mineral lubricating oil having a viscosity of 100-600 SUS at 100 F., viscosity index of at least 90 and 210% sulfur-containing aromatics of thiophenoiic and benzo thiophene structure and having incorporated therein from about 1% to about 10% each of lead naphthenate and sulfurized sperm oil.
- An improved gear oil composition consisting essentially of a mixture of two mineral oil fractions of: (1) 85% of a -140 VI Bright Stock having an aromatic content of 570% and (2) 45-15% of a mineral lubricating oil having a viscosity of -600 SUS at 100 F., viscosity index of at least 90 and 210% su1furcontaining aromatics of thiophenolic and benzothiophcne structure and having incorporated therein from about 1% to about 10% each of lead naphthenate and sulfurized sperm oil.
- composition of claim 2 containing from about 0.1% to 5% each of polyisobutylene and 4,4-methylene- (2,6-ditert-butylphenol).
