(57) [Abstract] [Objective] The cross-linking structure of the melamine resin forming the decorative layer of the melamine resin decorative board is improved to plasticize the decorative layer and improve the miscibility of the resin and the abrasion resistance-imparting agent. Improve the impregnation of the resin, the abrasion resistance of the decorative layer, and the sharpness of the printed pattern. [Constitution] 1. Aldehydes are added to 1 mol of melamine. 2-1.5 moles, para-toluenesulfonamide at 0. Melamine resin varnish 10 made by adding 1 mol or more to resin 0 parts by weight, 10 parts by weight of crystalline cellulose, 1 specific surface area A melamine resin-impregnated decorative paper 1, a phenol resin-impregnated paper 2 and a melamine obtained by impregnating a base paper for cosmetics with a resin solution obtained by adding 1 to 2 parts by weight of 50 to 200 m 2 / g of finely powdered silicic acid anhydride The resin-impregnated warpage-preventing paper 3 is overlaid and subjected to thermocompression molding to obtain a wear-resistant melamine resin decorative plate. |
