The invention relates to a base wallpaper, and particularly relates to a heat-resistant anti-fouling PVC base wallpaper with high opaqueness and a preparation method thereof. The base wallpaper is prepared from the following raw materials in parts by weight: 25-32 parts of mercerized wood pulp, 50-60 parts of sulfate coniferous pine wood pulp, 4-6 parts of ammonium polyphosphate, 0.2-0.4 part of nanocrystalline cuprous oxide, 1-2 parts of sodium pyrophosphate, 4-6 parts of a PAE wet strength agent, 0.2-0.3 part of sodium dodecyl benzene sulfonate, 1-2 parts of a water-based defoamer, 10-14 parts of 800-1250-mesh environment-friendly pigments, 1-2 parts of oxidized starch, 8-10 parts of talcum powder, 3-5 parts of titanium dioxide, 12-15 parts of an adhesive and 3-5 parts of an assistant. The base wallpaper disclosed by the invention contains oxidized starch-coated nano-cuprous oxide micro powder, and is capable of lastingly playing anti-fouling and antibacterial effects; the heat resistance, the strength and the opaqueness of the paper are effectively improved by the raw materials such as ammonium polyphosphate and titanium dioxide; the surface coating liquid is uniform and full in color and luster, good in retention effect, and high in utilization rate; the sized base wallpaper is flat and crisp in surface, excellent in physical property, and easy to process at a later stage; and a basis is laid for the production of a high-quality wallpaper product.
