Summary: | The invention provides an inorganic material for repairing a pottery jar and a repairing method, and relates to the technical field of post-treatment of pottery jars. The repairing material is prepared from the following raw material components in parts by weight: 24 to 35 parts of tricalcium silicate, 10 to 18 parts of dicalcium silicate, 6 to 12 parts of sulphoaluminate, 6 to 10 parts of calcium aluminate, 7 to 11 parts of calcium aluminoferrite, 3 to 7 parts of gypsum, 0.01 to 3 parts of active magnesium oxide, 0.01 to 3 parts of hectorite and 12 to 30 parts of filler. On the basis of a traditional cement-based material, a small amount of chemical reagent is added, the chemical reaction is carried out in a repairing material maintenance alkaline environment, so that the purpose of compensating drying shrinkage is achieved, better repairing interface strong bonding and compactness are achieved, the repairing material is in a non-flowing state but in a wet powder state by regulating and controlling the added |
