Definitions

  • the invention relates to silicone-free cutting oils and their use in band saw systems, for example when sawing polyurethane block foams and the production of furniture with such polyurethane foam parts, which show good results in fire tests.
  • Sawing systems require cutting oils to reduce the friction between the saw blade or saw band and the body to be cut.
  • band sawing systems are used in the processing of polyurethane block foams.
  • the friction between saw and polyurethane foam is particularly high, so that basically a cutting oil is needed.
  • silicone oils such as polydimethylsiloxanes having a viscosity of 5 to 1000 mPa s measured at 25 ° C.
  • high demands are placed on the cut polyurethane foam parts with respect to flame retardancy, especially if the foam parts are further processed into pieces of furniture such as mattresses or seating. It shows that foam parts, which were produced with silicone-containing cutting oils, achieve poor results in fire tests.
  • polyalkylene glycols can be used as cutting oils or in cutting oils and these cutting oils containing polyalkylene glycols, optionally solvents and optionally other auxiliaries and additives, solve this problem.
  • silicone-free means that no compounds are present which have Si-C or Si-O-C bonds.
  • the cutting oils of the invention preferably contain ethylene oxide / propylene oxide copolymers, which are preferably obtainable by copolymerizing ethylene oxide (EO) and propylene oxide (PO) with a polyhydric alcohol.
  • the cutting oils according to the invention preferably comprise polyalkylene glycols which are reacted with glycerol, trimethylolpropane, pentaerythritol, Diglycerol, triglycerol, ditrimethylolpropane, dipentaerythritol or sorbitol, most preferably pentaerythritol were prepared as a polyvalent starting alcohol.
  • the polyalkylene glycols contained in the cutting oils according to the invention preferably have an EO / PO weight ratio of from 80:20 to 40:60, preferably from 80:20 to 70:30 and preferably from 75:25.
  • the polyalkylene glycols preferably have an average molar mass of from 2,000 to 30,000 g / mol, particularly preferably from 3,500 to 20,000 g / mol and very particularly preferably from 5,000 to 7,500 g / mol.
  • the polyalkylene glycols contained in the cutting oils according to the invention are miscible with water in any ratio.
  • polyalkylene glycols which are contained in the cutting oils according to the invention can, for. B. commercially available polyalkylene glycols, such as polyglycol P41 / 300, polyglycol P41 / 3000 or polyglycol P41 / 12000 Clariant be.
  • polyalkylene glycols (often referred to as polyoxyalkylenes), which may be contained as polyalkylene glycol in the cutting oil according to the invention, as in the prior art, for.
  • polyoxyalkylenes polyalkylene glycols
  • the preparation of the polyalkylene glycols is preferably carried out in an alkaline catalyzed manner, and more preferably with pentaerythritol as the starting alcohol.
  • the cutting oil can also contain one or more solvents in addition to polyalkylene glycol.
  • the cutting oil preferably has from 1 to 99% by weight, preferably from 50 to 90% by weight, of solvent (s) B).
  • a preferred solvent is water.
  • the cutting oil according to the invention may comprise one or more auxiliary and / or additives C).
  • Preferred auxiliaries and / or additives C) may, for. B. conventional preservatives such as bactericides or fungicides z.
  • triethanolamine and corrosion inhibitors such as Hostacor ® IT, manufacturer Clariant be.
  • Another object of the invention is the use of the cutting oils according to the invention in sawing equipment, preferably in band sawing systems and more preferably in band sawing equipment for / sawing polyurethane foams or polyurethane block foams.
  • the present invention tailored polyurethane foam parts obtained by sawing, in particular band sawing polyurethane foams using cutting oil according to the invention and the use of polyurethane foam cut parts according to the invention for the production of articles with good fire properties, for the production of furniture and in particular for the production of furniture with good fire properties.
  • Good fire properties are understood to mean that the polyurethane foam parts pass the fire test in accordance with ASTM D 1692 (burned-out section maximum 125 mm).
  • Cutting oil according to the invention silicone-free, consisting of 99.5% by weight of polyglycol P 41/300, 0.5% by weight of triethanolamine.
  • Cutting oil according to the invention silicone-free, consisting of 49.5% by weight of polyglycol P 41/3000, 50% by weight of water, 0.5% by weight of triethanolamine.
  • Cutting oil according to the invention silicone-free, consisting of 10% by weight of polyglycol P 41/12000, 89.5% by weight of water, 0.5% by weight of triethanolamine.
  • the saw band of a band saw was coated with the particular cutting oil by rubbing it with a soaked rag and then determining the number of cutting operations that were possible before viscoelastic block foam ruptured due to excessive friction during cutting.
  • Foam parts of the predetermined size (150 mm ⁇ 50 mm ⁇ 13 mm) were sprayed with the example cutting oils (in each case about 10 g) and dried at room temperature for 48 hours.
  • the results of the Fire tests ASTM D 1692 in which the test specimen is placed horizontally on a sieve and is subjected to a flame from below for 60 seconds, is given in the burned-out distance (maximum 125 mm) (Table 1).
  • Table 1 Results of sawing tests and burn tests release agent Number of possible cutting operations Results ASTM D 1692 Distance (mm) 1 8th 102 2 8th 110 3 7 120 A 8th > 125, failed test
  • the silicone-free cutting oils used according to the invention are equivalent to classic silicone oil in terms of lubricity, but show significantly better results in the burn-off test according to ASTM D 1692.
