Abstract:
An aqueous lubricant for metal material plastic working, which can form a lubricating coating having excellent lubricity (moisture absorption resistance) under a high humidity environment, seizure resistance to metal working with high difficulty, and the like, and further has excellent long-term agent stability; a metal material having a lubricating coating formed by the aqueous lubricant on/over a surface of the metal material; and a metal processed article obtained by molding the metal material are provided. The above problem can be solved by using an aqueous lubricant for metal material plastic working in which an aliphatic polycarboxylic acid having 5 to 8 carbon atoms and a solubility in water at 20°C of 10 g/100 mL or more and an alkaline earth metal compound are blended in water, or an alkaline earth metal salt of the aliphatic polycarboxylic acid is dissolved or dispersed in water.
Abstract:
This invention refers to a magnetized intermetallic compound which may be applied as a basic lubricating oil in order to create a high performance finished lubricating oil. Magnetizing the intermetallic compound will confer to the finished lubricating oil when applied to a solid body, the ability of forming a magnetic film on the external surface of a solid body, and in so doing will confer to the additive a greater capacity to reduce friction, thus minimizing the effects of wear caused by contact between the surfaces of bodies of several dynamic systems.

A grease composition for use as a cable filling material which contains about 75 to 95 parts by weight of a base component of a liquid or semi-solid polyol having a molecular weight of at least 4000 and a reduced amount of mono-unsaturated compounds, about 1 to 15 parts by weight of a thickening agent such as colloidal particles of silica, and between 1 and 5 parts by weight of an antioxidant. Optionally, a thermoplastic elastomer can be added to improve bleed resistance.

Abstract:
Organoclay compositions which comprise the reaction product of a smectite-type clay having an ion exchange capacity of at least 50 meq. wt. per 100 g. clay (active basis), and a branched chain quaternary ammonium compound are useful self-activating and self-dispersing additives to liquid organic systems such as grease and ink formulations. Also included are grease and ink formulations using these organoclay compositions.

Abstract:
Adducts of clay, especially of the smectite variety, most especially bentonite, are prepared with an effective amount of at least one activated mixed metal oxide or oxy-hydroxide (AHMMO) formed by dehydrating hydrotalcite or a mixture comprising magnesium oxide and aluminum oxide, or a crystalline mixed metal hydroxide conforming substantially to the formula LimDdT(OH)¿(m+2d+3+n.a)(A?n)a.xH2O where m is zero to one, D is a divalent metal, d is from zero to 4, T is a trivalent metal, A represents at least one anion or negative-valence radical of valence n, where n is 1 or more, (m+2d+3+n.a) is equal to or greater than 3, (m+d) is greater than zero, and xH2O represents excess waters of hydration. These adducts are useful, e.g., in drilling muds and in viscosity modification of a wide variety of fluids.

An organophilic clay comprising the reaction product of:
(a) a smectite-type clay; (b) a first organic cation in an amount of from about 75% to about 150% of the cation exchange capacity of the smectite-type clay; and (c) a second organic cation provided by a polyalkoxylated quaternary ammonium salt; wherein the second organic cation is present in an amount of from about 0.01% to about 20% by weight of the total organic cation content.
The organophilic clay finds use in non-aqueous fluid systems.
