Effects of Adding Method of a Novel Haxogen-Free Flame Retardant Agent on the Properties of Wood-Plastic Composites

Abstract:

Phosphoric acid, pentaerythritol and aniline were used to synthesize a novel intumescent flame retardant agent(IFR), then IFR was added into high density polyethylene based wood plastic composites(WPC) by three different ways. Thermal degradation behavior, combustion properties and mechanical properties of WPC were evaluated by means of limiting oxygen index(LOI), thermogravimetric analysis(TGA), universal testing and scanning electron microscope(SEM) images of char formed after LOI tests. The results show that when IFR was added directly into WPC, the composite has the best flame resistant property, but the worst mechanical properties; when IFR is dissolved into solution, and the immersion method is adopted, the WPC has the best mechanical properties and better fire retardant property.
