Abstract (en)
[origin: WO8602292A1] A fiber board composition and a fiber board composite formed therefrom is capable of consolidation into a variety of structural building products ranging from flat sheets and panels which may interlock for modular housing to 2 x 4's through 2 x 12's, etc. The fiber board composition comprises lignocellulosic particles, such as softwood or hardwood waste particles, which have been pressure treated to resist insects and rot with a chemical compound, such as chromated copper arsenate, a vegetable matter derivative for increased strength, such as hominy feed; a fire retardant chemical, such as alumina tri-hydrate; and a water retardant chemical, such as casco wax, which are then consolidated into the formed fiber board structure by means of about 4 to about 10% by weight of a phenolic-type resin, pressures of about 400 to about 600 psi, heat of about 320 to about 360<o>F and ultrasonic sound with a frequency of about 3.6 to 3.7 mega hertz.
