Modification of PUR-PIR foams by boroorganic compound obtained on the basis of bis(hydroxymethyl)urea
Abstract
A method for the preparation of a boroorganic compound with the application of N,N'-bis(methyleneoxy-2-hydroxyethyl)urea and boric acid has been presented. The prepared borate was evaluated mainly in respect of its applicability as a polyol component and antipirene for the production of polyurethane-polyisocyanurate foams. The preparation method, the determination of foaming parameters and methods for the determination of physicomechanical properties and flammability of the PUR-PIR foams were described and the results were presented. On the basis of studies, it was found that application of the new compound in the preparation of foams was advantageous. The rigid foam obtained was characterized by reduced brittleness, higher ultimate compressive strength and a significantly reduced flammability in comparison with standard foam.
