Enhanced Thermal Stability and Flame Retardancy of Poly(Vinyl Chloride) Based Composites by Magnesium Borate Hydrate-Mechanically Activated Lignin

To improve the thermal stability and flame retardancy of poly(vinyl chloride) (PVC) based composites, magnesium borate hydrate-mechanically activated lignin (MBH-MAL) complex was in-situ synthesized by hydrothermal method for using as a novel additive. In addition, MBH-lignin (MBH-L) complex, MAL, MBH, and common mixing of MBH and MAL (MBH+MAL) were also prepared for comparative investigation. MBH-MAL showed synergistic improving effect on PVC...
