Definitions

  • the invention relates to a high-temperature lubricant for the non-cutting hot forming of metals, containing a solid lubricant and a residue-free decomposing organic product.
  • DE-OS 24 30 249 describes a high-temperature lubricant for the hot forming of metals on the basis of a phosphate-borate glass, an additive that burns the lubrication and a propellant that triggers a residue-free, decomposing organic product.
  • the addition of alkali phosphate borate melt products results in a product that has another disadvantage of poor wetting shows properties on hot surfaces.
  • the silica in turn has a bad influence on the lubrication behavior and the service life of the tools.
  • the object of the present invention was to propose a high-temperature lubricant which does not have the disadvantages mentioned and which leads to closed and fully effective lubricating films at temperatures above 600.degree.
  • the object is achieved with a high-temperature lubricant according to claim 1.
  • the inorganic additive suitably consists of a mixture of 0.2 to 25% by weight of boron compound, 0.2 to 98.8% by weight of polyphosphate and 1 to 99.6% by weight of alkali silicate.
  • the polyphosphate is used in insoluble or poorly soluble form.
  • Madrell's salts or Kurrol's salts are preferably used as polyphosphates. These are compounds of the type (Na PO 3 ) n with n greater than 6 D is 50,000, preferably 6 to 10,000.
  • the boron compound can be used in soluble and preferably in poorly soluble or insoluble form.
  • borax boric acid
  • B 2 0 3 KB 5 O 8 4H 2 O or zinc borate
  • zinc borate can be used as the boron compound.
  • the alkali silicate used is preferably a sodium water glass or potassium water glass with an SiO 2 content between 21 and 47%.
  • insoluble or sparingly soluble compound which is preferably mentioned is particularly advantageous with regard to the wetting of hot surfaces and in particular the uniform layer thickness of the high-temperature lubricant on the tool and / or workpiece surfaces at temperatures above 350 ° C. and in particular at 600 ° C. and above .
  • the quantitative ratios of the individual components can be 1 to 90% by weight for the solid lubricant, 1 to 50% by weight for the organic product which decomposes without heat, 1 to 80% by weight for the inorganic additive according to the invention and 0 for the organic stabilizer. 2 to 80% by weight.
  • the organic product which decomposes without residues is used in lubricants for use at temperatures of up to 350 ° C. in amounts of at most 50% by weight, and decreases linearly for temperatures of 600 ° C. and above to a maximum of 5% by weight , used.
  • Typical lubricants for use at temperatures of 350 ° C. can therefore contain 40 to 90% by weight solid lubricant, 10 to 50% by weight organic product, 0.2 to 5% by weight inorganic Additive and 0.2 to 5% by weight of organic stabilizing agent.
  • the composition is expediently 10 to 90% by weight solid lubricant, 1 to 15% by weight organic product, 10 to 80% by weight inorganic additive and 0.2 to 4% by weight of organic stabilizing agent.
  • Graphite, M O S 2 (molybdenum disulfide), CaF 2 or BN can be used as the solid lubricant.
  • graphite leads to particularly good results. From the range of graphites, those with high purity, for example over 96%, and an average grain size of not more than 300 micrometers are preferred. The best results can be achieved with a graphite of 99.5% purity and an average grain size of 100 micrometers.
  • the organic products which decompose without leaving any heat are, for example, alkylene homopolymers or copolymers.
  • alkylene homopolymers or copolymers include the homo- and copolymers of aryl alkenes, a, ⁇ -unsaturated acids and esters, ⁇ , ⁇ -unsaturated acids and esters, alkenes (monoolefins, diolefins etc.), vinyl esters, vinyl alcohols, unsaturated dibasic acids and esters (dicarboxylic acids and -ester), alkyl esters and acyclic acids and esters understood.

  • These polymers can be used alone or as a mixture with one another.
  • the high-temperature lubricant can also contain a number of other additives. This includes microbiologically active components and wetting agents.
  • silicic acid which is usually in the form of highly disperse silicon oxide and which must be used as a stabilizer in compositions which contain polyphosphates, is particularly advantageous in the case of lubricants according to the invention.
  • the silica itself is undesirable because it has a bad influence on the lubrication behavior and on the service life of the tools.
  • Erfindungsgeäss should be present as 5-56 GEV% aqueous dispersion of the high-temperature lubricant for G e-consumption.
  • the dispersion expediently has a viscosity of 500 to 15000 cp at 10 to 30 ° C.
  • the organic stabilizer contained in the high-temperature lubricant may be sufficient to achieve the viscosity of the dispersion.
  • suitable thickeners e.g. water-soluble polysaccharides, alkyl celluloses, polyvinyl alcohols, polyarylates, polyvinyl pyrrolidone, optionally minerals, such as clays.
  • the high-temperature lubricant is usually used in the form of an aqueous dispersion.
  • the aqueous dispersion can be applied to the tool and / or the workpiece to be machined, which can have temperatures of 100 to over 900 ° C. When the hot surfaces are touched, the water evaporates and a film of uniform layer thickness forms.
  • the high-temperature lubricant can also be used in powder be used form.
  • the tool and / or the workpiece is powdered or rolled or drawn through the lubricant.
  • the lubricants according to the invention are particularly suitable for use at temperatures around 600 ° C. and above.
  • the high temperature stability of the lubricants and in particular the stability of the lubricating film was essentially achieved through the high proportion of inorganic additives.
  • the high-temperature lubricant according to the invention is therefore suitable, for example, for the lubrication of tools, e.g. Mandrel, mandrel bar or die, and workpieces, for example blanks or tubes, for hot forming in so-called “multiple pipe mills", continuous lines, mitral mills, Assel lines, push bench systems, bar presses or upsetting presses.
  • tools e.g. Mandrel, mandrel bar or die
  • workpieces for example blanks or tubes
  • the high-temperature lubricant had a viscosity of 1900 C ps, measured at 20 ° C according to Epprecht with a Rheomat 15 of the Contraves.
  • the present formulation showed the most favorable properties at relatively low application temperatures of 20 to 250 ° C in contours or consist streets.
  • the above-mentioned formulation was sprayed onto tools (e.g. mandrels) using a spray device.
  • the coefficient of friction was 0.037.
  • a high temperature lubricant was prepared as a 70 wt% aqueous dispersion.
  • the lubricating constituents corresponded to the formulation according to Example 1, but 5% by weight zinc borate was used instead of the borax.
