Effect of Inorganic Flame Retardant on the Properties of Wood/PVC Composites

Abstract:

This study was conducted to research on the effect of the mechanical and flame retardant properties of wood/PVC composites after being treated by three different types and contents of inorganic flame retardant (Al (OH)₃, ZB and Sb₂O₃). The result indicated that it had an obviously descending tendency for impact flexibility with content of inorganic flame retardant increased, as for tensile strength it would increase in one appointed range and a reduction also took place around another specific range except ZB. The effect rank of the three kinds of inorganic flame retardant when they reached the hard burn level of Chinese standards (OI≥32) was Sb₂O₃(6%)>ZB(10%) >A1(OH)₃(30%) in sequence. Synthetically taking into account mechanical and flame retardant properties, it was evidently concluded that the optimum choice of the three inorganic flame retardant for Wood/PVC composites was ZB in production.
