The invention discloses an insulating layer plastering gypsum, belonging to building materials and solving the problems that cement is high in production energy consumption and has high usage amount when serving as the building construction material, so that the usable area can be reduced. The insulating layer plastering gypsum comprises the following components in parts by weight: 30-70 parts of semi-hydrated gypsum powder, 10-30 parts of anhydrous gypsum powder, 1-20 parts of flyash, 1-10 parts of quartz sand, 1-5 parts of perlite, 0.1-3 parts of polyvinyl alcohol (PVA), 0.1-3 parts of carboxymethyl cellulose (CMC), 0.1-0.5 part of methyl cellulose (MC), 0.1-2 parts of citric acid and 0.1-3 parts of K12 foaming agent. When the insulating layer plastering gypsum is made, after being ground, the components are mixed and stirred for 10-60 minutes or undergo secondary stirring, thus obtaining the insulating layer plastering gypsum. The insulating layer plastering gypsum is low in energy consumption ...
