Wallpaper glutinous glue powder as well as preparation method and application thereof

The invention provides wallpaper glutinous glue powder. The wallpaper glutinous glue powder is prepared from the following raw materials in parts by weight: 80 to 120 parts of potato starch, 1 to 2 parts of an ionic alkali, 0.05 to 0.08 part of a cross-linking agent, 10 to 20 parts of sodium polyacrylate, 20 to 30 parts of sodium polyacrylamide, 0.05 to 0.1 part of a mildew preventive and 60 to 80parts of water. The potato starch is used as a main raw material, graft polymerization is carried out on starch branched chains through modification, and therefore the glutinous glue powder has the advantages of being high in viscosity, proper in initial viscosity, stable in freezing and thawing performance and good in fluidity and film forming performance, the defect that tacky-dry performance is insufficient after other starch adhesives are used is overcome, and the glutinous glue powder is suitable for being used for various kinds of wallpaper. 本发明提供一种墙纸糯胶粉，所述墙纸糯胶粉的制备原料按重量份数计包括如下组分：马铃薯淀粉80-120份、离子碱1-2份、交联剂0.05-0.0
