Research on structure and performance of polyurethane elastomer/superfine talcum powder composite

Abstract

The structure and performance of polyurethane elastomer/superfine talcum powder composites were investigated by X ray diffraction ( XRD), FTIR spectra and thermogravimetric analysis ( TG - DTA, DSC ). The results showed that talcum powder and polyurethane elastomer formed com pound structure of heterogeneous nucleation when the content of superfine talcum powder was right(such as 15% ), which caused the soft segments, hard segments and talcum powder of polyurethane elastomer to form interactional congeries system and the integrated mechanical properties and thermostability of polyurethane elastomer were improved.
