Definitions

• As a modifier 0.56% iso octyl phenol was added, the soap and modifier being mixed into about 92% of a low cold test mineral oil having a viscosity of 900 to 1000 S. S. U. at 100 F. with addition of a small amount, about 0.25% of a tackiness agent, such as an oil solution of polybutene.
• the following table shows the various characteristics of greases containing different amounts of aluminum soap (aluminum ste'aratm the 'isooctyl phenol structure modifier siderably less in theexamples where the fatty acid was employed.
• the optimum composition covered by this table appears to be that consisting of 3% aluminum steara'te, 0.56% iso-o'ctyl phenol and 1.2% fatty acid.
• Stearic acid may be used as the saturated iat ty acid or various hydrogenated vegetable or fish oil acids which are commercially available maybe employed. lhe optimum quantity of the free or excess fatty acid to be used appears to be in the range of about 10 to 20%, based on the quantity of aluminum soap employed.
• the aluminum soap is preferably aluminum stearate although other substantially saturated aluminum soaps having between 12 and 22 carbon atoms may be used if desired.
• the added or excess acid appears to have a synergisticeifect on the grease modifier (iso-octyl phenol, as in the example given above). For this reason a considerably lesser-quantity of the modifier can be employed than in thecase where no free acid is used.
• the aluminum stearate grease obtained from commercial source C listed in the table above had particularly good structure stability when prepared on a laboratory scale by rapid cooling. It appears to have excellent structure stability even under conditions of high shear and to give Structure stability of aluminum stearate pressure lubricant Aluminum Soap Source A B 7 0 Manufacturing Process Cooler Pan Cooler Pan Cooler Pan Formulation Y Aluminum Stearate percent '7. 00 8. 9. 8. 00 6. 50 Iso-octyl Phenol d0 1. 40 1. 70 l. 60 Tackmess A ent (10---. 0. 25 O. 25 0. 25 O. 25 0. 25 0. 25 Mineral Oil do 91. 35 93. 75 89. 90. 75 90. 15 93. 25
• the fatty acid may be from 1 to 3 times the quantity of the alkyl phenol. Generally speaking, the quantities employed will be between 0.25 and 2.0% for the fatty acid and 0.25 and 1.25% for the alkylated phenol modifier. For greases containing soaps of good commercial quality the range may often be even narrower. Based on the amount of soap used in the grease, the added fatty acid may be from about 10 to 20% by weight. A good over-all formula for the finished lubricant appears to be 5 to 9% by weight of aluminum soap of saturated or substantially saturated fatty acid, for example aluminum stearate, 89 to 94% of mineral lubricating oil of appropriate grade, i. e. of 35 to 1000 S. S. U. viscosity at 210 F.
• the added acid is preferably stearic acid, although the other saturated fatty acids having between 12 and 22 carbon atoms, and mixtures thereof, may be employed.
• the phenol type modifier is preferably an alkylated phenol, particularly iso-octyl phenol, but other phenols such as resorcinol may be used, as described in application Serial No. 638,431 by Beerbower and Zimmer, now Patent No. 2,449,580.
• a tackiness agent also is usually desirable, though not indispensable. It is commonly used in quantities of 0.1 to 0.5% and other conventional additives such as corrosion inhibitors, oxidation inhibitors, extreme pressure agents, and the like, may be employed, as will be understood by those skilled in the art.
