Wang, Zi-Qiang published the artcileEffect of sodium lignosulfonate/nano calcium carbonate composite filler on properties of isotactic polypropylene, SDS of cas: 31570-04-4, the publication is Polymer Bulletin (Heidelberg, Germany), database is CAplus.
A novel composite filler sodium lignosulfonate/nano calcium carbonate (SL/CaCO3) was prepared by dry ball milling. Thermogravimetric anal. revealed that the composite filler SL/CaCO3 had improved thermal properties. The crystallization and melting behavior of isotactic polypropylene (iPP) modified by the composite filler was studied by differential scanning calorimetry. The best complex ratio (1:3) and optimal addition amount (2 weight%) of iPP nucleated by SL/CaCO3 were confirmed. The results reflected that a small amount of SL/CaCO3 into iPP could improve the nucleation ability, and excellent mech. properties were obtained. The relative contents of β-crystals (Kβ) in iPP were above 0.83 after addition of the composite filler. At the same time, nano CaCO3 played a significant role in crystallizing the iPP nucleated and greatly influenced the content of β-crystals. The elongation at break was increased by 32.27% and the impact strength was increased by 62.38% compared to those of pure iPP.
