PURPOSE: Provided is a method for bonding printing paper to plywood floor, which comprises bonding printing paper instead of natural patterned wood to plywood floor to reduce the cost for the preparation of the flooring materials. CONSTITUTION: The method comprises the steps of applying adhesives in the thickness of 50 to 100 g/m2 on the plywood floor, landing two pieces of laminated printing paper on the adhesives, compressing by using hot press at temperatures of 110 to 130 deg.C and under pressures of 100 to 150 kg/cm3 for 0.5 to 2 min, and cooling in the air at room temperature for 2 to 4 hours. The adhesives are the blends of 50 to 60 wt% of melamine, 20 to 30 wt% of latex, 10 to 20 wt% of starch and 0.1 to 0.5 wt% of hardener. The hardeners are those having high hardening rate and efficiency such as ammonium chloride.
