Meanwhile, the anti-bending ELP according to the present invention may further comprise a step of drying the printing paper impregnated in the water-based resin, curing the water-based resin, and coating the melamine resin on the upper and lower sides of the printing paper.

The strength of the antifouling ELP according to the present invention can be enhanced by coating melamine resin on the upper and lower sides of the cured printing paper, thereby causing a warp phenomenon when the MFB (melamine faced board) is used .

For example, the melamine resin may comprise 35 to 40 parts by weight of melamine, 25 to 30 parts by weight of formaldehyde, 20 to 30 parts by weight of water, 2 to 4 parts by weight of diethylene glycol and 1 to 3 parts by weight of sodium hydroxide By weight, and the pH of the mixed solution is adjusted to 8.0 to 8.5, and the mixed solution is polymerized at a temperature of 88 to 92 ° C for 2 to 4 hours, and the polymerized reactant Was cooled to 30 to 35 DEG C and the pH was adjusted to 7.0 to 7.5.
