Method for coating melamine impregnated paper on surface of multi-layer board

The invention discloses a method for coating melamine impregnated paper on the surface of a multi-layer board, which sequentially comprises the following steps: firstly, putting the melamine impregnated paper the surface of which is sprayed with AL2O3 on the multi-layer board bonded with glue after surface treatment; then, putting the multi-layer board into a multi-layer board die holder in a pressing machine, and hermetically pressing the multi-layer board by the pressing machine; and after pressing, taking out the coated multi-layer board. The invention has the advantages that the wearing coefficient of the surface sprayed with AL2O3 reaches 2000-6000 revolutions, the method can be used for manufacturing products such as floors, pedals and the like, the pressure is reduced, the wood grains on the surface of the wood and the sand shadow of the substrate can not rebound, and the coated surface is more smooth and attractive.
