Definitions

  • a significant disadvantage of both methods is the lack of self-cleaning of the mixing device ⁇ static mixer or stirred tube reactor) in contrast to a close-meshing twin-screw extruder.
  • the result in the process in dead zones product deposits that lead to the constriction and finally to close the free Strdmungsquer baines the static mixer or the tubular reactor and limit the stability and the continuity of the manufacturing process.
  • the very short mixing and residence times especially in the case of the reaction premix with the aid of the static mixer, promote subsequent product end mixtures in the extruder, with adverse consequences, in particular on the homogeneity of the material.
  • a separation of mixing process and gentle polymer structure by combining a self-cleaning twin-screw extruder with a directly downstream single-screw extruder is in DE-A 23 02564 in order to avoid 0- Overheating of the finished product proposed.
  • the critical reaction phase in which the reaction mixture has strong tackiness and a viscosity in the range between about 200 and 700 poise, in a screw zone consisting of kneading elements at Knetfre- frequencies to about 15 Hz and a velocity gradient in the radial clearance between the comb and the housing wall of more than 2000 s -1 .
  • the maximum velocity gradient in the sheared product is given as 4170 s -1 in the radial clearance.
  • the compounds having an average of at least 1, 8 and at most 3.0 Zerewitinoff-active hydrogen atoms are also understood as meaning the essentially linear isocyanate-reactive substances customary in polyurethane chemistry or a mixture thereof.
  • Customary isocyanate-reactive groups are in particular hydroxyl groups, in addition to amino groups, mercapto groups or carboxylic acid groups. These are preferably polyesterols, polyetherols or polycarbonate diols.
  • Suitable catalysts include organic metal compounds such as titanic acid esters, iron compounds, tin compounds, for example, tin diacetate, tin dioctoate, tin dilaurate, dibutyltin diacetate, and dibutyltin dilaurate.
  • Common auxiliaries and additives are, for example, plasticizers, lubricants, molecular clarifier, flame retardants, inorganic / organic fillers, dyes, pigments and stabilizers against hydrolysis, light and thermal degradation.
  • twin-screw extruder type ZSK 43 Mv Werner & Pfleiderer, Stuttgart are, for example, twin-screw extruder type ZSK 43 Mv Werner & Pfleiderer, Stuttgart.
  • the speed gradient (synonym: heavy speed) in an extruder is defined by the following equation:
