- the isocyanate-reactive component B may be first reacted with the isocyanate component C to form a prepolymer and then foamed with the polyol formulation A.
- Another possibility is to first mix the isocyanate-reactive component B with the polyol formulation A and then to foam it with the isocyanate component C.
- the isocyanate-reactive component B it is preferable to react the isocyanate-reactive component B first with the isocyanate component C to give a prepolymer and then to foam the prepolymer with the polyol formulation A.
- the polyurethane foams can be produced as molded or also as block foams.
- the molded foams can be produced hot or cold-curing.
- the invention therefore relates to a process for the preparation of the polyurethane foams, the polyurethane foams produced by this process and their use for the production of molded parts or block goods, as well as the molded parts or the block product itself.
- the polyurethane foams obtainable according to the invention find, for example, the following application: furniture upholstery, textile inserts, mattresses, automobile seats, headrests, armrests, sponges and components, as well as seat and armature panels, and have ratios of 70 to 130, preferably 80 to 120 and 4 to 4 room weights 600 kg / m 3 , preferably 60 to 120 kg / m 3 (soft foam), or 15 to 55 (semi-rigid foam) on.
- the isocyanate / isocyanate mixture / prepolymer is weighed into a suitable beaker and emptied again (flow time: 3 s). This, still wetted on the inner walls cup is tared and filled again with the specified amount of isocyanate.
- the isocyanate is added to the polyol formulation (flow time: 3 seconds).
- the mixture is mixed intensively with an agitator (Pendraulik) for 5 seconds.
- a stopwatch is started, from which the characteristic reaction times are read off. Approximately 93 grams of the reaction mixture are poured into a 23 ° C Teflon-lined aluminum box mold of 1.6 dm 3 volume. The mold is closed and locked.
- the lock is opened, released, and the mold pressure is qualitatively assessed by the molding height of the mold cover [mm].
- the demolded foam pad is assessed qualitatively with regard to reaction as well as skin and pore structure. The reaction kinetics are determined on the remainder of the reaction mixture in the beaker.
- Compression hardness and damping were measured on test specimens of 5 * 5 * 5 cm 3 parallel to the AufMumplatz at 40% compression. A pre-load of 2 kPa was set. The feed rate was 50 mm / min.
- the hydroxyl number was determined according to DIN 53240.
- a foam plate of size 40 * 10 * 2 cm 3 attached freely suspended so that the foam is not in contact with the aqueous solution at the bottom of the bottle.
- the bottle is closed and stored for 3 hours in a convection oven at 60 ° C. Allow the bottle to cool to room temperature, remove the foam.
- An aliquot of the aqueous solution is reacted with a solution of 0.3 mmol / liter dinitrophenylhydrazine (DNPH) in 3 mM phosphoric acid acetonitrile.
- DNPH dinitrophenylhydrazine
- the composition of the aqueous solution is analyzed by LC-MS / MS on the hydrazones of the aldehydes given below. For each foam quality, three bottles are examined. For each test run, three bottles without foam are examined. The mean blank value is subtracted from the measured values. On this basis, the emission of the respective aldehydes per kilogram of foam is calculated back. The information is given in mg aldehyde per kg foam.
- Measurement method 2 modified bottle method
- a one liter glass bottle add 25 milliliters of water and 25 milliliters of a solution of 0.3 mmol / liter dinitrophenylhydrazine (DNPH) in 3 mM phosphoric acid acetonitrile.
- the content of DNPH is 7.5 ⁇ per bottle.
- a foam plate of size 40 * 10 * 4 cm 3 attached freely suspended so that the foam is not in contact with the aqueous solution at the bottom of the bottle.
- the bottle is closed and placed in a convection oven at 65 ° C for 3 hours stored.
- polyol component was a polyether mixture of a glycerol-started
- the polyol component also contains various additives.
- color paste is black paste Isopur N (ISL chemistry)
- foam stabilizer is Tegostab B8734LF2 (Evonik)
- Cell opener is a glycerine-initiated polyalkylene oxide with an OH number of 37 mg
- HEAA hydroxyethylacrylamide
