The formaldehyde‐free resin impregnated paper is expected to be applied to interior decoration materials and furniture. This is not only conducive to the development of indoor environment toward green and environmental protection, but also beneficial to people's health. In this work, the formaldehyde‐free resin (waterborne polyurethane and waterborne acrylic acid) mixed with cellulose nanocrystal (CNC) were separately coated on a raw decorative paper by a dipping method to obtain formaldehyde‐free impregnated paper with outstanding surface bound strength and abrasion resistance. The surface bound strength and abrasion resistance were tested by means of universal ability test machine and abrasion tester. The results showed that waterborne polyurethane and waterborne acrylic acid enhanced by CNC had excellent dispersion, and the bonding properties of formaldehyde‐free impregnated paper were improved by 41.3 and 33.3%, respectively. Meanwhile, the abrasion resistance of formaldehyde‐free impregnated paper was improved by the crystal effect of CNC. © 2020 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020 , 137 , 48931.
