Dirt-resistant decorative paper and preparation method thereof

The invention discloses stain-resistant decorative paper and a preparation method thereof, and belongs to the technical field of decorative paper. The preparation method comprises the following steps: firstly, preparing dipping glue, secondly, carrying out multi-pass roller printing on base paper, drying, then completely immersing into the dipping glue for 30-60 seconds, drying at 80-90 DEG C after dipping, completely immersing into the dipping glue again for 5-10 seconds, and finally drying at 90-100 DEG C, so as to prepare the stain-resistant decorative paper. The base paper is impregnated in the impregnating adhesive for multiple times and dried, the impregnating adhesive contains the raw materials such as the waterborne acrylate emulsion, the inorganic filler and the coupling agent, the waterborne acrylate emulsion contains an auxiliary agent containing a quaternary ammonium salt structure and a triazine structure, and the auxiliary agent can stably exist in the impregnating adhesive; the inorganic filler
