Abstract:
1. Aqueous acidic reactive lubricant for the treatment of metal surfaces prior to cold forming with a content of phosphate ions and emulsifyable organic lubricant constituent, characterized in that it contains a) 0,2 to 15% by weight phosphate ions, b) as organic lubricant constituent 0,3 to 16% by weight of an organic carboxylic acid or an alcohol having 8 to 40 carbon atoms including esters, mono- or polyamides, mono- or polyalkyl ammonium salts having 1 to 18 carbon atoms in the alkyl chain or mixtures thereof, c) as emulsifying agent 0,1 to 10% by weight of an oxazoline wax and/or of a compound of the formula R-(NH-CH2 -CH2 -CH2 )n NH2 , wherein n is 1 to 5 and R contains a number of carbon atoms corresponding to tallow fatty acid (tallow alkyl), d) as chelating agent 0.25 to 3% by weight of ethylendiaminetetraacetic acid, the alkali metal and/or ammonium salts respectively.
Abstract:
For use as surfactants in oil water systems, e.g hydraulic fluids, compounds are described which contain in the molecule a hydrophobic component and a hydrophilic component covalently bonded together, where the hydrophobic component is a saturated or unsaturated C30-500 hydrocarbon chain and the hydrophilic component contains an anionic grouping selected from phosphate, phosphonate, sulphate, sulphonate and carboxymethyl.
Abstract:
Improved hydraulic fluids or metalworking lubricants, utilizing mixtures of water, metal lubricants, metal corrosion inhibitors, and an associative polyether thickener, have reduced dependence of the viscosity on temperature achieved by the incorporation therein of an ethoxylated polyether surfactant.

1438215 High temperature metal working lubricant LONZA Ltd 15 Oct 1974 [8 May 1974 6 Sept 1974] 44571/74 Heading C5F A high temperature metal working lubricant comprising by wt. (a) 10-90% graphite, (b) 2-60% polymer or copolymer of an ethylenically unsaturated compound, (c) 0À2-8% dispersion or suspension agent, (d) 0-40% film stabilizer. The unsaturated monomers may be vinyl esters, allyl esters, mono- or diolefins, acrylic acid or esters thereof, styrene or unsaturated dicarboxylic acid esters. The dispersion or suspension agent (c) may be a polysaccharide, an alkyl cellulose, or an alginate. The film stabilizer (d) may be a sodium silicate, boron oxide, a phosphate, silicic acid or a mixture thereof. Polymers used in the examples are a vinylacetate-dibutyl maleate copolymer, polyisobutylene, acrylic acid-styrene copolymer, ethylene - vinylacetate copolymer and polyvinylacetate.
