Flame-retardant gravel wallpaper printing process

The invention relates to the field of printing, in particular to a flame-retardant gravel wallpaper printing process. The process includes the steps that gravel and paper pulp are stirred through a stirrer to form flowing gravel and paper pulp paste; the surface of base paper is evenly and smoothly coated with the gravel and paper pulp paste, and after heating, a coating semi-finished product is formed; printing is performed on the coating surface of the coating semi-finished product to form a printing semi-finished product; the printing semi-finished product is subjected to warming embossing shaping; wallpaper obtained after embossing shaping is dried; after the surface of the dried wallpaper is treated through cooking-variation-resistant and high-temperature-resistant ink, rolling is performed, and then flame-retardant gravel wallpaper is obtained. The flame-retardant gravel wallpaper obtained through the flame-retardant gravel wallpaper printing process has a flame-retardant effect, higher safety, certain elasticity and high tear resistance, has a strong texture with various patterns and embossed lines formed, is easy to paste, is easy to replace after getting old, can be wiped through cloth due to the non-water-absorbing surface, and has the advantages of being good in handfeel, large in embossing depth, clear in grain and strong in stereoscopic sensation.
