Preparation and Properties of Rigid Polyurethane Foams Reinforced by Sepiolite Minerals Nanofibers

Abstract:

Rigid polyurethane foams were prepared using sepiolite nanofibers as main functional fillers. The effect of sepiolite nanofibers on the properties of polyurethane foams was studied systematically. Through characterization by scanning electron microscope, X-ray diffraction and property test, it was found that the thermal insulation effect can be maintained, and the mechanical properties can be improved due to the good interfacial bond between sepiolite nanofibers and rigid polyurethane foams.
