Abstract:
Alkaline diamine track lubricants for use with glass, aluminum and two-piece PET containers and other articles of manufacture are prepared from an admixture of an alkyl diamine and a water-soluble hydrotrope. The diamine lubricants are prepared without the neutralization thereof and have a corrosion inhibitor which is, preferably, a reducing agent and a biocide incorporated thereinto. A source of alkalinity may be employed, as well, to maintain the pH above 8.
Abstract:
A grease composition for high-temperature, high-speed and high-load bearings comprises (i) a lubricating base oil composed of an alkyldiphenyl ether lubricant as an essential ingredient and having a kinematic viscosity of 90-160 cSt at 40.degree. C., and (ii) 22-30 wt. %, based on the grease composition, of a diurea compound as a thickener. The diurea compound is represented by the following formula: ##STR1## wherein R.sub.2 means an aromatic hydrocarbon group having 6-15 carbon atoms, R.sub.1 and R.sub.3 denote an aromatic hydrocarbon group having 6-12 carbon atoms or a linear alkyl group having 8-20 carbon atoms, and the proportion of aromatic hydrocarbon groups in R.sub.1 and R.sub.3 is 70-95 mole %. The NLGI thickness grade of said composition is in a range of from No. 1 to No. 3.

A composition for lubricating a metal workpiece prior to cold forming consists essentially of: an aqueous alkaline stearate compound present in an amount sufficient to impart metal lubrication between about 180.degree. F. and about 320.degree. F.; an aqueous alkaline palmitate compound present in an amount sufficient to impart metal lubrication below about 160.degree. F.; an aqueous metallic stearate compound present in an amount sufficient to impart metal lubrication between about 320.degree. F. and 440.degree. F.; a polymeric glycol present in an amount sufficient to provide temperature stability, act as a carrier for the aqueous compounds, and impart a waxy lubrication to the metal; a compound present in an amount sufficient to act as a carrier for the aqueous compounds and to provide a translucent film barrier on the metal; an alkaline buffering agent present in an amount sufficient to provide dispersion, viscosity and stability; a hydrotropic agent present in an amount sufficient to solubilize the lubricating composition. A process is disclosed for lubricating a metal workpiece outer surface prior to cold forming, the process comprising the step of disposing a non-reactive lubricating composition on the workpiece outer surface, the outer surface having been alkaline cleaned, hot water rinsed, acid pickled, and cold water rinsed.
