α-Zirconium Phosphate Apply in PP

Polypropylene/a-ZrP nanocomposites were prepared by melt blending using polystyryl quaternary ammonium salt (CM-PSQAS) as compatibilizer. Then the morphology thermal stability and mechanical properties of the nanocomposites have been studied. XRD results indicated that the β-type crystals of Polypropylene were observed. The results of TGA indicated that the thermal stability of the nanocomposites was enhanced, and even at a low α-ZrP loading of 1%. The thermal degradation temperature was enhanced by 18% compared with the virgin polymer. The heat distortion temperatures of nanocomposites were increased although the increments were minor. The mechanical properties testing results indicated that the tensile strength, tensile modulus and impact strength increased with the increase of α-ZrP loading, and increments of the tensile strength ,stretch modulus and impact strength were 6.5%, 39%, 29% respectively when the loading ofα-ZrP was 5%.
