Abstract Polystyrene-based wood plastic composites (WPCs) containing ammonium polyphosphate (APP) and iron (Fe) powder were prepared in this work by solution blending with the aid of an alternating magnetic field. The mechanical, electrical, thermal and fire performances of the WPCs were analyzed through mechanical testing, thermogravimetry and CONE calorimeter. The addition of Fe powder decreased the tensile strength and increased the impact strength. The APP promoted the formation of sufficient char on the material’s surface and enhanced the flame retardant properties. Furthermore, an alternating magnetic field was used to align the Fe powders. After the magnetic treatment, the electrical conductivity and thermal properties were found to increase considerably compared with those without treatment. The Agari model presented the most reasonable prediction of thermal conductivity as a function of Fe content among three classical thermal conduction models. According to the morphological observations, the iron particles in the composites tended to rearrange along the direction of the magnetic field after treatment, resulting in the enhancement of both thermal and electrical conductivities. The prepared WPCs in this study exhibited good flame retardant properties together with the acceptable mechanical properties of the composites.

In this study, by preparing red pottery clay according to unearthed red pottery clay pieces and using red pottery clay to reinforce high-density polyethylene-based wood–plastic composites, the effects of the amount of red pottery clay on the properties of the fabricated wood–plastic composites were investigated. The results indicated that when the amount of red pottery clay increased, flexural strength and impact strength of the composite initially increased and then decreased; flexural modulus increased and tensile strength and elongation at break decreased. The cone calorimeter tests studied the effects of red pottery clay on the flame retardant and smoke suppressant behaviors of high-density polyethylene-based wood–plastic composites. Red pottery clay formed a ceramic structure on the surface and inside high-density polyethylene, thus preventing high-density polyethylene from interacting with oxygen and increasing the amount of available carbon. As a result, the flame retardant properties of wood–plastic composites were improved due to the addition of red pottery clay. A comprehensive evaluation of the properties of high-density polyethylene-based wood–plastic composites reinforced with red pottery clay showed that addition of 5% of red pottery clay resulted in the most optimal mechanical properties: the addition of red pottery clay improved the density of the composite, decreased the shrinkage rate, and enhanced the flame retardant properties.

Thermal Degradation Behavior

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.

Resistance To Heat

Wood-plastic composites (WPC), a fast growing class of material used by the furniture and building industry for its excellent mechanical performance and functionality. However, WPC is easily combust because the raw material of it, i.e. wood and plastic burns so easily which result in more fire dangers of WPC. Unfortunately, in the case of WPC, few researchers have carried out to reduce its flammability which still has a long way to go. In this paper, the current development of halogen-free flame retardant WPC at domestic and abroad was reviewed. Especially, the fire retarded WPC with phosphorus, nitrogen, boron, silicon and other flame retardant elements, the fire retarded mechanism, the problems, such as poor compatability, bad resistance to heat and limitation of wood adding quantity, and the solution to the problems were emphasized.
