NOVELTY - Regeneration water glass sand modified composition comprises 10-15 pts. wt. graphene micropiece, 5-10 pts. wt. rare earth oxide, 15-20 pts. wt. xylitol solution, 2-4 pts. wt. yeast powder, 1-3 pts. wt. capsaicin, 2-4 pts. wt. nanosilicon nitride and 2-3 pts. wt. hydroxypropyl- beta -cyclodextrin. USE - Regeneration water glass sand modified composition. ADVANTAGE - The low cost composition increases mold intensity, increases recycling rate, and improves collapsible and moisture-resistant storing character of water glass. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of regeneration water glass sand modified composition comprising adding rare earth oxide, nanosilicon nitride and xylitol solution in stainless heating tank, heating, stirring at 120 revolutions/minute, heating to 90-110 degrees C, adding graphene micropiece, yeast powder, capsaicin and hydroxypropyl- beta -cyclodextrin, stirring for 60-65 minutes; injecting into stainless steel cooling bed, freezing for 12 hours at -6 degrees C; placing in refrigerating bed at 0-- 2 degrees C for 24 hours, condensing crystals, seeping out water; oven drying at 60 degrees C until moisture content is less than 13%; and ball milling to 400 meshes powders.
