| titleOfInvention | Method for producing rigid polyurethane-polyisocyanurate foams |
| abstract | The subject of the invention is a process for the production of polyurethane-polyisocyanurate foams, consisting in the reaction of polymeric 4,4'-diisocyanatodiphenylmethane with a polyol with the participation of 33% potassium acetate solution in diethylene glycol, 33% solution of triethylenediamine in dipropylene glycol, polysiloxane polypropylene (2 -chloro-1-methylethyl), a mixture of 1,1,1,3,3-pentafluorobutane and 1,1,1,2,3,3,3-heptafluoropropane and natural filler in the form of ground oak bark, pine, larch, beech, apple, pear or poplar, especially oak. The method is characterized by the fact that the reaction is carried out by adding ground bark to the recipe in an amount of 5 wt.%. (15.9 g) up to 25 wt.% % (79.3 g), most preferably from 5 wt. (15.9 g) up to 20 wt.% (63.4 g) based on the sum of the weights of polyol and polyisocyanate. |
