Wall painting starch adhesive powder, and preparation method and application thereof

The invention provides a wall painting starch adhesive powder. The wall painting starch adhesive powder is prepared from the following raw materials, by weight: 65 to 80 parts of corn starch, 20 to 35 parts of potato starch, 2.5 to 5 parts of an ionic alkali, 0.03 to 0.05 part of a cross-linking agent, 8 to 15 parts of an oxidant, 20 to 25 parts of sodium polyacrylate, 0.5 to 2 parts of sodium polyacrylamide, 0.05 to 0.1 part of a mildew preventive and 80 to 100 parts of water. According to the preparation method of the wall painting starch adhesive powder, corn starch and potato starch are mixed at a certain ratio, sodium polyacrylate is adopted for grafting copolymerization, and sodium polyacrylamide is adopted for complexing, so that the prepared wall painting starch adhesive powder possesses proper initial viscosity and post-viscosity, good freeze-thaw property, film-forming property and flowability, and is convenient for applying and wall painting movement adjusting. 本发明提供一种壁画糯胶粉，所述壁画糯胶粉的制备原料按重量份数计包括如下组分
