Abstract

This research studies on properties of added boron compound particleboard panels for improving of the potential in fire retardant. Using Boric acid and Borax (BA : BX) mixture (1 : 1.5), BA : BX (1.5 : 1) and Disodium octaborate tetrahydrate (DOT), at 1%, 1.5% and 2% content were applied to the particleboard with urea formaldehyde. Physical and mechanical properties of treated particleboard were evaluated according to Thai Industrial Standard for Flat Pressed Particleboards (TIS) 876-2004. Fire retardant property was determined by flammability testing (25.853) provided by Federal Aviation Regulations (FAR). Particleboard treated with BA : BX (1 : 1.5) at 2% showing the best fire-retardant property, particularly in terms of burn length and flame time, but modulus of rupture and internal bonding value of particleboard did not meet the standard of TIS 876-2004. The fire retardants affected the physical and mechanical properties of particleboard. However, boron compounds had excellent fire retardants effectiveness over untreated.
