Antibacterial mildew-proof impregnating adhesive for decorative paper and preparation method of antibacterial mildew-proof impregnating adhesive

The invention belongs to the technical field of special paper manufacturing, and particularly relates to an antibacterial mildew-proof impregnating adhesive for decorative paper and a preparation method of the antibacterial mildew-proof impregnating adhesive. The antibacterial and mildew-proof impregnating adhesive for the decorative paper comprises acrylic resin, polyurethane, a cross-linking agent, a curing agent, a flatting agent, an antibacterial and mildew-proof agent and water. The environment-friendly water-based acrylic resin and the polyurethane are compounded to serve as main raw materials, the performance requirements of the cladded decorative paper for the surface hardness and the material toughness are balanced, meanwhile, the content of formaldehyde in the finished decorative paper is reduced, and after the broad-spectrum antibacterial agent with the excellent heat resistance is added, the heat resistance of the decorative paper is improved. When the prepared impregnating adhesive is applied to
