Composites of Reduced Flammability Based on Amorphous Elastic Polyurethane and Halogen-containing Flame Retardant

Abstract

The effect of a mixture of halogen-containing fl ame retardants based on chloroparaffins and 1,1,9-trihydroperfl uorononanol-1 immobilized on a montmorillonite carrier on the character of reducing the fl ammability of polyurethane was studied. Using X-ray diffraction and sol-gel analysis, the structural and morphological features of the elastomers obtained were studied. It has been revealed that intercalation of macromolecular chains of a matrix amorphous polymer into the intralayer spaces of a fl uorine-containing organoclay occurs with an increase in a degree of structural perfection of the macromolecular system that contributes to an increase in the fire resistance of the resulting polyurethane composites.
