| Résumé : |
Regenerated leather billet (semi-finished product) was prepared via hot pressing with chrome shaving and environment-friendly polymer waterborne polyurethanes (WPU) as the materials. The influence of WPU/chrome shaving ratios (w/w) on the performance of the billet was investigated by mechanical property test, dynamic thermal mechanical analysis, thermogravimetric analysis, differential scanning calorimetry and field-emission scanning electron microscopy. Furthermore, the ability of heat storage and temperature regulation was endowed for the regenerated leather by the addition of paraffin microcapsules. The results showed that a strong interface interaction could be achieved for the regenerated leather billet, which could be due to the formation of hydrogen bonds and the entanglement between WPU and leather shavings. In this way, WPU/leather shaving composites with favorable mechanical properties, thermal stability, ability of heat storage and temperature regulation were obtained. |
