PROCESS FOR THE PREPARATION OF RECYCLED POLYOLS FROM RIGID FOAM RESIDUES OF POLYURETHANE AND / OR POLYISOCIANURATE. |
| abstract |
Process for the preparation of polyolsnrecycled from residues of rigid polyurethane foam and / ornpolyisocyanurate This process involves the reaction of the wastenmade of rigid polyurethane foam (PUR) and / or polyisocyanurate (PIR) withna short chain compound containing at least 2 groupsnhydroxyl (OH) in the presence of a catalyst and subsequentnTreatment with a mixture of organic acids. This process isnobtains a recycled polyol that has a low content ofnprimary aromatic amines and that can be used fornsubsequent manufacture of new rigid polyurethane foams,npolyurea-polyurethane or polyisocyanurate. |
