The method comprises the following steps: adding nanometer silicon dioxide into ethylene glycol for dissolving; adding purified terephthalic acid, and carrying out an esterification reaction to obtain an esterified product; mixing diethylene glycol with dibasic acid, adding a titanium catalyst, and carrying out a polymerization reaction to obtain a prepolymer; adjusting temperature and pressure, and carrying out a hybrid reaction on the esterified product and the prepolymer to obtain a PETraw material with a melting point of 110-120 DEG C; carrying out melt extrusion on the PET raw material, and carrying out needling, hot bonding or spinning melting treatment to obtain a PET non-wovenfabric; pretreating the PET non-woven fabric with the melting point ranging from 110 DEG C to 120 DEG C and a PET non-woven fabric with a melting point ranging from 225 DEG C to 260 DEG C to obtain aPET non-woven fabric pre-material; and cutting, hot-pressing and cooling the pre-material to obtain the furniture board. The preparation method is simple and stable in process and suitable for large-scale industrial production.
