Abstract: PROBLEM TO BE SOLVED: To upgrade the productivity by first applying a thermoset synthetic resin adhesive to wood chips, then applying a diphenyl methane and a diisocyanate to the coat to form the wood chips into platelike products and thermally pressing these products into moldings. SOLUTION: After spraying a urea melamine co-condensation resin adhesive to wood chips, a biphenyl methane and a diisocyanate (MDI) (emulsification-type) are sprayed to the coat and the wood chips are thermally formed under pressure into platelike moldings. The MDI does not become set but only after passing through a heat press-molding process, when the urea resin adhesive is blended with a curing agent because it is acidic. The content of the MDI to be added to the adhesive is as specified to the solid content of the adhesive. When the content of the MDI added is below the specified level, the shortening effect of time required for heat press- molding is not shown, while the manufacturing cost is increased when the content of the MDI added is above the specified level.  In addition to the adhesive component, a wax emulsion which imparts water resistance, an ammonium chloride as a curing agent, an urea as a formalin absorbent or the like is properly added. Thus it is possible to shorten the heat press-molding time, upgrade the productivity and decrease the content of the adhesive applied.
