| titleOfInvention | Process for the preparation of polyisocyanurate foams having reduced thermal conductivity |
| abstract | a) organischen und/oder modifizierten organischen Polyisocyanatennmit b) mindestens einer höhermolekularen Verbindung mit mindestensnzwei reaktiven Wasserstoffatomen und gegebenenfalls c) niedermolekularen Kettenverlängerungs- und/oder Vernetzungsmitteln nin Gegenwart von d) Katalysatoren, e) gegebenenfalls Treibmitteln f) sowie gegebenenfalls weiteren Hilfsmitteln und/oder Zusatzstoffen, ndas dadurch gekennzeichnet ist, daß als Komponente b) mindestensnein Recyclatpolyol, welches durch Glykolyse von Polyisocyanuratschaumstoffennunter Verwendung von Trägerpolyolen mit einer OH-Zahlnvon höchstens 500 mg KOH/g und einer Molmasse von mindestensn450 g/mol entsteht, eingesetzt wird. The invention relates to a method for producing polyisocyanurate foams with reduced thermal conductivity by reacting a) with organic and / or modified organic polyisocyanates b) at least one higher molecular weight compound with at least two reactive hydrogen atoms and optionally c) low molecular weight chain extenders and / or crosslinking agents in the presence of d) catalysts, e) optionally blowing agents f) and optionally further auxiliaries and / or additives, which is characterized in that at least one recyclate polyol which is formed by glycolysis of polyisocyanurate foams using carrier polyols having an OH number of at most 500 mg KOH / g and a molar mass of at least 450 g / mol is used as component b). n n n The invention further relates to those produced by this processnPIR foams and their use for thermal insulation. |
