Effective Role

This work aimed to use magnesium hydroxide (MH) as a flame retardant in poly(lactic acid) (PLA)/high impact polystyrene (HIPS)/wood flour (WF) composite. The 80/20/20 PLA/HIPS/WF composite was melt mixed with three loadings (20, 30 and 40 phr) of MH on a twin screw extruder, followed by an injection molding. The prepared wood-plastic composites (WPCs) were investigated for their impact strength (IS), tensile strength (TS), Young’s modulus (E), elongation at break (EB), flammability and morphology. The results showed that the 80/20/20 PLA/HIPS/WF composite exhibited higher IS, TS and E than the neat PLA, but at the expense of reducing the EB. It was also found that the WPCs filled with MH at all loadings provided much higher flame resistance and E over the neat PLA, HIPS, PLA/HIPS blend and PLA/HIPS/WF composite. Therefore, the MH could play an effective role as flame retardant in the WPCs.

The feasibility of producing HIPS of UL-94 5V flammability rating has been demonstrated. Results of TGA, XRD and SEM enable the role of such components as brominated organic flame retardant, antimony trioxide, chlorin ated polyethylene and magnesium hydroxide in flame retardancy of 5VA HIPS to be evaluated.
