| Abstract: | Polypropylene material is modified by adding different amounts of SAPO-34 molecular sieve as additive, and then SAPO-34
molecular sieve polypropylene composite material were prepared by melt extrusion. By means of differential simultaneous scanning
thermal analyzer (TG-DSC), X-ray diffractometer (XRD) and scanning electron microscope (SEM), the microstructure and morphology
of polypropylene composite material modified by SAPO-34 molecular sieve were characterized. The mechanical properties of the
composites were studied by universal material testing machine and pendulum impact testing machine. The results show that the addition
of SAPO-34 molecular sieve can significantly improve the mechanical properties of polypropylene. The maximum tensile and impact
strength can be achieved when the SAPO-34 molecular sieve is added in 5%. The maximum tensile strength can reach 1 171 N, which
is 14.5% higher than pure polypropylene material, and the maximum impact strength can reach 6.39 kJ/m2 with an increase of 47.2%. |
