| 摘要 | A blend of isotactic polypropylene (PP) with high-density polyethylene (HDPE) in different PP/HDPE ratios was irradiated by gamma-ray to induce cross-linking and then foamed using supercritical carbon dioxide (scCO(2)) as a blowing agent. Radiation effect on the melting point and crystallinity were analyzed in detail. The average cell diameter and cell density were compared for PP/HDPE foams prepared under different conditions. The optimum absorbed dose for the scCO(2) foaming of PP/HDPE in terms of foaming ability and cell structure was 20 kGy. Tensile measurements showed that the elongation at break and tensile strength at break of the crosslinked PP/HDPE foams were higher than the non-crosslinked ones. Of particular interest was the increase in the foaming temperature window from 4 degrees C for pristine PP to 8-12 degrees C for the radiation crosslinked PP/HDPE blends. This implies much easier handling of scCO(2) foaming of crosslinked PP with the addition of HDPE. |
