<p>PROBLEM TO BE SOLVED: To enable the effective utilization of a waste decorative plate by laminating a paper backing melamine resin-impregnated pattern layer on a regenerated craft paper backing phenol resin-impregnated core layer in which regenerated craft paper made from a crushed melamine decorative plate and craft pulp is impregnated with a phenol resin. SOLUTION: A paper backing melamine resin-impregnated pattern layer is laminated on a regenerated craft paper backing phenol resin-impregnated core layer in which regenerated craft paper prepared from a crushed melamine decorative plate and craft pulp is impregnated with a phenol resin. As regards the crushed melamine decorative plate, the melamine decorative plate is crushed by a crusher and pulverized by a high speed cross flow mill to make the particle size 150 micron or below. Accordingly, since the phenol resin binds the crushed material and the craft pulp together, the crushed material is held surely among craft pulp fibers and made to have enough flexural strength, and a high quality melamine decorative plate is obtained.</p> |
