    摘要: Disclosed is a solid or aqueous lubricant concentrate used for the cold forming of metals, which, with reference to the solids content, including a) 20 to 50 parts by weight polyethylene with a softening point above 120.degree. C. and a particle size int he range between 0.1 and 50 .mu.m; b) 20 to 8 parts by weight polyacrylate with a molecular weight of 4,500 to 10,000 and c) 2 to 8 parts by weight styrene/acrylic acid copolymer with a molecular weight of 150,000 to 250,000 and a glass transition temperature of 45 to 55.degree. C., where, under the conditions of use, the acrylic acid component of the polymers in accordance with items b) and c) is predominantly present as salt of one or more inorganic cations, and the softening points of the individuals polymers are distributed over the temperature range defined by the limiting values of ambient temperature and 200.degree. C. The lubricant concentrate may contain homo-or copolymers or acrylic acid or the esters thereof with graded molecular weights as well as surfacant. Also disclosed is a method for facilitating the cold forming, where, by means of the lubricant concentrate, a lubricant film is applied on the workpiece from a dispersion having solids content of 5 to 25 wt-%.

    摘要: The invention relates to a method for regenerating reaction lubricant residues containing acid organic lubricants refused and processed during cold forming and multivalent metal ions and phosphate ions, wherein said reaction lubricant residues undergo the following procedural steps: a) precipitating metal ions from the metal organic compounds by adding phosphoric acid and/or acid phosphoric acid esters; b) dissolving water-soluble impurities by adding water; c) separating the solids from the lubricant components and from the aqueous phases that are incompatible with the oily lubricant components, and whereby d) acid phosphoric acid esters for adjusting the free acid at a value of less than 10 points and for adjusting a total acidity point value of less than 70 is adjusted at a free acid. total acidity ratio having a value in the range of 0.15 to 0.5. The separation indicated in step c) preferably occurs by means of a centrifuge at 2,000 to 3,000 g, especially at 8,000 to 15,000 g.
