Abstract:
A waterborne lubricant for the cold plastic working of metals that contains alkali metal salts of dimer(s) and/or trimer(s) of unsaturated fatty acids with from 10 to 24 carbon atoms per molecule has a lubrication performance at least as good as that of prior lubricants, even at generally lower lubricating film weights, has a long bath life, and generates little dust during cold plastic working operations. Even as little as 5 % of these salts of dimer(s) and/or trimer(s) of unsaturated fatty acids, when mixed with conventional alkali metal salts of saturated fatty acids with from 10-24 carbon atoms per molecule, can provide these benefits.
Abstract:
A metal-working water or a metal-working composition which has excellent cooling and lubricating properties and does not exert a harmful influence on the environment. A metal-working water containing sodium ion and one or more kinds selected from the group consisting of fluoride ion, hydrogencarbonate ion and silicon and being adjusted to pH 6.0 to pH 10 can be used as a substitute for a conventional cutting oil. A metal-working composition including a metal-working water with such additive as a rust-preventive agent and being adjusted to pH 6.0 to pH 10 can also be used.
Abstract:
A graphite-free lubricating oil which comprises a base oil having dispersed therein 10 to 40% by weight of a carbohydrate and/or a derivative thereof whose particle size ranges from 10 to 150 mu m, 2 to 20% by weight of a film-boosting agent and 0.1 to 20% by weight of a dispersant. Moreover, the lubricating oil is free of black-colored substances such as graphite. Therefore, the oil permits the improvement of working surroundings and exhibits excellent properties such as formability through forging almost comparable to or even greater than that of the commercially available graphite-in-oil type lubricating oils. The lubricating oil can be used instead of the graphite-containing lubricating oils for warm forging, hot forging, rolling, tube-manufacturing, drawing and extrusion in place of the graphite-containing lubricating oils and ensures the improvement in the working surroundings and excellent lubricity.
Abstract:
A diesel lubricant exhibiting improved ability to minimize undesirable viscosity increases when used in diesel engines is described. More particularly, in accordance with the present invention, a diesel lubricant is described which comprises a major amount of an oil of lubricating viscosity and a minor amount, sufficient to minimize undesirable viscosity increases of the lubricant when used in diesel engines, of a composition comprising (A) at least one carboxylic derivative composition produced by reacting at least one substituted succinic acylating agent with at least one amino compound containing at least one -NH- group wherein said acylating agent consists of substituent groups and succinic groups wherein the substituent groups are derived from polyalkene characterized by an Mn value of at least about 1200 and an Mw/Mn ratio of at least about 1.5, and wherein said acylating agents are characterized by the presence within their structure of an average of at least about 1.3 succinic groups for each equivalent weight of substituent groups, and (B) at least one basic alkali or alkaline earth metal salt of at least one acidic organic compound having a metal ratio of at least about 2. The composition should have a TBN in the range of about 6 to about 15, with the sucinnic acid derivative contributing about 0.5 to 1.5 TBN to the composition. The alkali or alkaline earth metal salts (detergents) should contribute the rest of the TBN of the composition. TBN is measured by the ASTM D2896 method. Magnesium should contribute less than about 30% of the total TBN of the composition. The invention also includes methods for operating diesel engines which comprises lubricating said engines during operation with the diesel lubricants of the invention.

Abstract:
A lubricant is provided for use in hot working such as cross-roll rolling of a seamless steel pipe. It effectively reduces the friction coefficient between the working tools and the material under the hot work, thus extending the lives of the tools. The lubricant contains: (A) from about 10 to about 60 wt% of alkali silicate; (B) from about 1 to about 20 wt% of silane coupling agent; (C) from about 0.1 to about 5.0 wt% of at least one kind of alkali compound selected from a group consisting of an alkali hydroxide, an alkali carbonate, an alkali borate and an alkali salt of mineral acid; and (D) from about 30 to about 70 wt% of water. Alternatively, the lubricant contains: (A) from about 10 to about 60 wt% of alkali silicate; (B) from about 1 to about 20 wt% of silane coupling agent; (C) from about 0.1 to about 5.0 wt% of at least one kind of alkali compound selected from a group consisting of an alkali hydroxide, an alkali carbonate, an alkali borate and an alkali salt of mineral acid; (D) from about 5 to about 50 wt% of water; (E) from about 10 to about 60 wt% of iron oxide; and (F) from about 0.1 to about 5.0 wt% of at least one additive selected from a group consisting of a dispersant and a thickening agent.

A lubricant and surface conditioner for formed metal surfaces, particularly aluminum and tin beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. The conditioner includes (i) a water-soluble organic material selected from amine oxides and quaternary ammonium salts, ethoxylated castor oil derivatives, and imidazoline moiety-containing phosphonates and preferably also includes (ii) at least one of fluozirconate, fluohafnate, or fluotitanate ion, and (iii) phosphate and/or nitrate ions. Good resistance to damaging the friction reducing effect by overheating and to staining of the domes of treated containers during pasteurization can be achieved.
