The invention discloses a wood
fiber composite facing ecological board and a manufacturing method thereof. Wood fibers are selected, and the thickness of the wood fibers ranges from 0.2 mm to 0.6 mm;the
moisture content of the wood fibers is 0-9%; an
adhesive is adopted for adhesion, and is applied and stirred in the fibers; the
adhesive application amount is 7-35% of the weight of the wood fibers; 0.3-0.6% of waterproof agent and 0.1-0.4% of
mildew preventive are added; after the application, the
moisture content of the fibers is dried to 3 to 15 percent; upper and lower surfaces of a laminated wood board core or a plywood core in the thickness of 5-21 mm, length of 2450 mm to 2750 mm and width of 1230 mm to 1310 mm are coated with the
adhesive, and the
coating weight of a single surfaceis 100-120g / m2; the uniformly stirred wood fibers is uniformly laid on the upper and lower surfaces of the facing board core for
hot pressing at the
hot pressing temperature of 100-150 DEG C; the actual unit pressure and time are divided into three sections for
hot pressing, then board collecting, and then stacking and natural curing are conducted for more than 7 days, edge sawing and sanding thickness determination are conducted, and the wood
fiber composite facing ecological board is manufactured by conducting high-temperature hot pressing on the two faces and impregnating adhesive film paper. The wood
fiber composite facing ecological board is high in flatness, high in
surface bonding strength, low in
water content, stable in size, resistant to
cracking and good in cold and hot cycle resistance.
