Machine-spraying-type plastering gypsum mortar and preparation technology thereof
The invention relates to machine-spraying-type plastering gypsum and a preparation technology thereof and belongs to the technical field of building materials. The machine-spraying-type plastering gypsum is characterized by being prepared from the following raw materials: 200-400 parts of gypsum, 10-60 parts of cement, 520-650 parts of fine aggregate, 80-160 parts of heavy calcium powder, 2-4 parts of redispersible emulsion powder, 2-4 parts of hydroxypropyl methyl cellulose ether, 0.15-0.25 part of an air entraining agent, 5-10 parts of expanded perlite, 0.3-0.8 part of a gypsum retarder and 200-300 parts of water. The machine-spraying-type plastering gypsum is applicable to being directly sprayed to a wall surface by adopting a mortar spraying machine, both time and labour are saved, construction efficiency can be improved, and cost is reduced; bonding performance with the wall surface is good, rebounce is not caused, anti-sagging performance is good, both bonding strength and compressive strength can meet requirements, and cracking of a wall body can be reduced; and usage amount of gypsum is low, and cost can be effectively reduced.
