Eurofillers 2013

10th anniversary meeting will be organized in Bratislava, Slovakia on August 25 – 29, 2013. The focus and scope of fillers have gone through considerable changes during last years, since the interest of the industry as well as academia partly shifted from traditional fillers to other heterogeneous systems. Bio- or natural fillers reinforcement composites find application and are still interesting for development. Downsizing of fillers from micro- to nano-dimensions is bringing new possibility of combining improvement of physical-mechanical properties of polymer materials with special functionalities of nanofillers. New trends and application of filled polymeric materials will be also presented in the conference.

Synthesis of functionalized α-zirconium phosphate modified with intumescent flame retardant and its application in PLA

Recently published article: Polymer Degradation and Stability, Volume 98, Issue 9, September 2013.

Abstract

A novel functionalized α-zirconium phosphate (F-ZrP) modified with intumescent flame retardant was synthesized by co-precipitation method and characterized. Poly (lactic acid) (PLA)/F-ZrP nanocomposites were prepared by melt blending method. The thermal stability and combustion behavior of PLA/F-ZrP nanocomposites were investigated by thermogravimetric analysis (TGA), limiting oxygen index (LOI), vertical burning test (UL-94), scanning electronic microscopy (SEM), and cone calorimeter test (CCT). The results showed that the addition of flame retardant F-ZrP slightly affect PLA’s thermal stability, but significantly improve the flame retardancy of PLA composites. In comparison with neat PLA, the LOI value of PLA/F-ZrP was increased from 19.0 to 26.5, and the UL-94 rating was enhanced to V-0 as the loading of F-ZrP at 10%. SEM results suggested the introduction of F-ZrP in the PLA system can form compact intumescent char layer during burning. All these results showed that the F-ZrP performed good flame retardancy for PLA.
