Abstract: The invention relates to a method for the production of lightweight building boards comprising at least one outer layer and a core layer adhesively bonded to this, the adhesive being applied to at least one outer layer, wherein the application of the adhesive is effected by means of a rotating disk which is mounted horizontally or with a slight deviation of up to 15° from the horizontal, preferably parallel to the outer layer.

Abstract: A method for the preparation of polyisocyanurate foams with reduced thermal conductivity, comprises reacting optionally modified organic polyisocyanates (A) with at least one high mol.wt. compound (B) containing two or more reactive hydrogen atoms and optionally with low mol.wt. chain extenders and/or cross-linking agents (C), in the presence of catalysts (D), optional propellants (E) and optional auxiliary agents and/or additives (F). At least one recycled polyol obtained by glycolysis of polyisocyanurate foam using carrier polyols with a maximum OH content of 500 mg KOH/g and molar mass of at least 450 g/mole, is used as (B). Also claimed are polyisocyanurate foams prepared by the above method.
