It has a certain resin content and volatile matter content and can be glued together or to artificial board substrates through hot pressing. Melamine-impregnated paper has the advantages of improving the appearance of materials, increasing their use value, improving physical properties, expanding their application range, increasing the value of artificial boards, and simplifying the production process of artificial boards (avoiding processes such as painting and coating).

[0004] The melamine-impregnated paper in the above cases did not have ideal crack resistance, and its surface abrasion resistance was also unsatisfactory. This led to cracking and abrasion problems during the use of the melamine-impregnated paper, which seriously affected its service life. Therefore, we provide a melamine-impregnated paper that is abrasion-resistant and crack-resistant. Utility Model Content
