Properties of FA/PP Composite in Different Proportions

Fly ash (FA) and polypropylene (PP) composites in different proportions were prepared by melt blending, and their antistatic property, thermal stability property and crystallization property were analyzed. The results show that fly ash could improve the antistatic property, thermal stability property of the composite, and the crystallization rate increases when a small amount of fly ash is added. While the mass fraction of fly ash was 15%, the composite had the best performance, giving the surface resistivity, volume resistivity and thermal deformation temperature 2.04×1011 Ω, 1.78×1011 Ω·cm, 66.1 ℃,respectively.
