Abstract

The invention discloses heat preservation type inner wall plastering anhydrite and a method. The heat preservation type inner wall plastering anhydrite is prepared from the following matters in partsby weight: 400 to 450 parts of alpha type hemihydrates gypsum, 200 to 300 parts of a microcapsule phase-change material, 50 to 100 parts of calcium triple superphosphate, 20 to 70 parts of quartz sand, 50 to 60 parts of glass beads, 15 to 20 parts of redispersible emulsion powder, 0.5 part of starch ether, 2.5 parts of cellulose ether and 0.4 part of retarder. A preparation method of the heat preservation type inner wall plastering anhydrite comprises the following steps: weighing all raw materials in parts by mass, sequentially adding the raw materials in weightlessness dry blending equipment, and starting the weightlessness dry blending equipment for blending after completing addition of all the raw materials; discharging and packaging after uniformly stirring. The heat preservation typeinner wall plastering anhydrite disclosed by the invention is mainly applied to inner wall plastering, the thickness which is 1 to 2 cm can be achieved through one-time construction, and the heat preservation type inner wall plastering anhydrite has a good heat preservation and heat insulation function except the technical effects of common plastering anhydrite construction.

Description

technical field [0001] The invention relates to a plaster for plastering and a method thereof, in particular to a plaster for plastering a heat-retaining interior wall and a method for plastering. Background technique [0002] The traditional material used for interior wall plastering is mainly interior wall plastering mortar, but with the increase in the number of building developments year by year, the demand for interior wall plastering mortar is also increasing, and the supply has been in short supply. [0003] Plastering gypsum is a new type of interior wall leveling material compounded with gypsum as the cementitious material by adding lightweight inorganic materials, aggregates or other additives. It has been widely used as a substitute for interior wall plastering mortar. This material has the functions of being environmentally friendly, improving construction efficiency, sound insulation and humidity control, etc., and it can be initially set in a few minutes at roo...
