As shown in Table 1, in order to examine the performance of the hot melt adhesive for furniture coatings prepared in examples 1 to 3 and comparative examples 1 to 2, the mechanical properties of MDF substrates were tested 24 hours after the MDF substrates were coated with veneers by means of a universal coating machine. After the roller coating of the ultraviolet curing UV paint, the solvent in the paint can penetrate into the glue layer through the coated wood veneer downwards, and the bonding effect is damaged. The APAO high polymer in the examples 1-3 has high molecular chain regularity and low branching degree, so that the bonding is difficult to damage by a solvent, and the APAO high polymer has certain solvent resistance, and the EVA in the comparative examples 1 and 2 has high branching degree, so that the bonding structure is easy to damage by the solvent, and the bonding structure is not solvent-resistant, so that after an organic solvent in the UV paint permeates into a glue layer, a semi-finished product is subjected to photocuring to generate foaming or stripping at high temperature in UV rays, and the quality of the finished product cannot reach the standard. The coating amount also affects the number of the output materials of the product in the coating process, and in comparative examples 1 and 2, the coating amount is more than that in examples 1 to 3 and the output material number is low because the initial adhesion and the bonding strength of the coating are insufficient and the density is high.
