Gypsum mortar and preparation method thereof
The invention discloses gypsum mortar. The gypsum mortar is prepared from the following raw materials in parts by weight: 120-160 parts of desulfurized gypsum, 20-32 parts of cement, 5-10 parts of fine sand, 18-37 parts of a mineral admixture, 25-50 parts of glass beads, 50-80 parts of fly ash, 10-15 parts of lignocellulose, 2-5 parts of a water reducing agent, 1-3 parts of a water retaining agent, 1-3 parts of a mildew preventive, 5-12 parts of dispersible latex powder, 3-5 parts of a retarder and 1-2 parts of a defoaming agent, with the balance being water, wherein the mineral admixture comprises 20-30 parts of blast furnace slag, 5-10 parts of bentonite, 20-30 parts of silica powder, 15-20 parts of heavy calcium carbonate, 5-10 parts of talcum powder and water. The gypsum mortar of the invention has the advantages of mildew resistance, light weight, compactness, sound insulation performance and structural stability under long-term use, and is beneficial to meeting the requirements of industrial production.
