Burn-resistant plastic compositions
Abstract
Abstract SOLID BURN-RESISTANT POLYMERIC COMPOSITIONS ARE FORMED BY REACTING SUBSTANCES SUCH AS C1(PNCL2)9PCL4 AND (PNCL2)3-4 WITH EPOXY RESINS TO FORM PNCL2-EPOXY PREPOLYMERS. THESE PREPOLYMERS ARE BLENDED WITH ORGANIC LIQUID PREPOLYMERS SUCH AS PHENOLICS, EPOXIES, POLYURETHANES AND POLYESTERS AND THE BLENDS ARE CURED TO FORM FIRE RESISTANT PLASTICS, WHEREIN INITIAL P, N, AND CL CONTENTS ARE WHOLLY RETAINED. THOSE TWO COMPONENTS, I.E., PNCL2 COMPONENT AND EPOXY RESIN ARE ADMIXED WITH LIQUID ORGANIC PREPOLYMERS (AND POLYMERIZATION CATALYSTS THEREFOR) AND THE SYSTEM IS THEN CURED, USUALLY BY HEATING, WHEREBY THE PNCL2-EPOXY POLYMER IS FORMED IN SITU ALONG WITH THE MATRIX POLYMER, OR IN SOME CASES CHEMICALLY BONDED TO THE ORGANIC POLYMERIC CROSS-LINKED PLASTIC.
