Abstract

Abstract:

Polypropylene/fly ash （PPFP1919/FA） micro foaming composites were prepared by chemical micro foaming method， and the rheological properties， foaming quality and mechanical properties of PPFP1919/FA composites with different FA content were studied. The results shows that the dispersion of FA in PPFP1919 matrix can improve the melt strength， melt elasticity and foaming ability of the composites. In addition， FA also plays a heterogeneous nucleation role in the foaming process， providing nucleation point， which improves the foaming quality and foaming effect， and the mechanical properties of the composites after foaming are affected to a certain extent. Comprehensive analysis shows that when FA content was 10 phr， the foaming effect of PPFP1919/FA micro foaming composite is the best.

Key words: fly ash, polypropylene, composite, foaming property
