Abstract

Six kinds of Ni-base catalysts were prepared by combustion method and then their catalytic carbonization and combustible properties for polypropylene were tested. The results showed that the catalytic activity of Ni-Al and Ni-Mg catalytic systems are better than single Ni catalyst,the residual char of PP are 43.7% and 41.8%, respectively, compact char layer mainly composed of carbon nanotubes was formed and the peak heat release speed(PHRR)was decreased dramatically. There was a little difference between Ni-Co and Ni catalytic system of residual char, but the formers of structure of char layer is superior to the latter. Catalytic carbonization of Ni-Cu, Ni-Zn and Ni-Fe system were less effective than Ni catalyst.
