  • Patent number: 6194357
    Abstract: Waterborne lubricants comprising: (A) water-soluble inorganic salt; (B) homogeneously dispersed solid lubricant; (C) at least one homogeneously emulsified substance selected from mineral oils, animal and plant oils and fats, and synthetic oils; (D) surfactant; and (E) water, in which the weight ratio (B)/(A) is from 0.05:1 to 2:1 and the weight ratio {C/(A+B)} is from 0.05:1 to 1:1, provide a one-step, highly lubricating waterborne lubricant for use in the cold plastic working of metals. This waterborne lubricant can replace the conversion coating treatment (phosphate, oxalate, etc.)+reactive soap treatment combined lubrication system now in general use and is free of the environmental issues associated with the combined lubrication system, provides for facile coating removal, and is not subject to the decline in seizure resistance caused by nonuniform add-on when large numbers of workpieces are treated together by immersion.

  • Patent number: 5877129
    Abstract: A lubricant additive including a borate dispersion, wherein the lubricant additive is a dispersion of an alkali metal salt of boric acid in a mixture of an alkaline earth metal salt of a salicylic acid and an alkenylsuccinimide. The lubricant additive provides a high dropping point for grease used under a high temperature condition of 130.degree. C. or higher and per se exhibits anti-oxidant performance. A lubricant grease composition containing the lubricating additive is also disclosed.

  • Patent number: 5584945
    Abstract: Disclosed is a lubricant carrier salt for facilitating the cold forming of a workpiece of iron or steel, based on boric acid and/or alkali borate. The salt has an additional content of aliphatic di- or tricarboxylic acid, which either is unsubstituted or substituted by at least one hydroxyl group, and/or of alkali salts thereof, the weight ratio of boric acid/alkali borate to the acid is (5 to 15):1. Especially appropriate carboxylic acids are malonic acid, maleic acid, succinic acid, tartaric acid and/or citric acid.Inorganic or organic thickening agents, such as bentonite and/or polysaccharide, aluminate and/or silicate, dispersants, lubricants and/or antioxidants as well as titanium salt can be contained as additional components in the lubricant carrier salt of the invention.

  • Patent number: 5547595
    Abstract: A lubricant composition including ethoxylated long chain primary alcohols and, preferably, boron compounds but excluding most other previously used organic lubricant materials gives superior results in tube pointing operations, especially with thick walled tubes, and is also useful for drawing operations, either subsequent to pointing or independently of pointing, where very high quality surface finishes are desired.

  • Patent number: 5531912
    Abstract: A stearate free solid lubricant for cold working of metals contains approximately equal amounts of an alkene-acrylate ionomer and an alkoxylated alcohol in which the alcohol moiety has from 18-60 carbon atoms and the alkoxylate block has about the same number of carbon atoms. This lubricant can be conveniently applied from aqueous solution/suspension and works effectively even when the underlying steel surface has no conversion coating, which is usually required with stearate lubricants for best results.
