Abstract

The invention discloses heat-insulating plastering gypsum for a building interior wall and a preparation method thereof and relates to the technical field of plastering gypsum. The heat-insulating plastering gypsum comprises 55-75 parts of desulfurized gypsum, 20-30 parts of natural gypsum, 15-20 parts of cement, 15-20 parts of heat-insulating filler, 10-15 parts of modified heavy calcium carbonate, 10-15 parts of plant source additive, 5-10 parts of rubber powder, 5-10 parts of modified expandable graphite and 7-12 parts of auxiliary. The preparation method includes: pretreating the natural gypsum. The heat-insulating plastering gypsum is used for being brushed on the building interior wall, is excellent in heat-insulating performance and has high adhesiveness, and a coating is free of shrinking and cracking and less prone to shedding.

Description

technical field [0001] The invention relates to the technical field of plastering gypsum, in particular to a thermal insulation plastering plaster used for building inner walls and a preparation method thereof. Background technique [0002] In recent years, the leveling requirements for building interior decoration, appearance requirements and environmental protection requirements have become higher and higher, so the interior decoration materials are required to have harmless and environmental protection characteristics, and plaster plaster is an inorganic material, non-toxic, harmless, fireproof and environmentally friendly. It is used for plastering various walls and ceilings in buildings, and the gypsum itself contains 2 crystal waters, which can discharge water when the external environment is dry, so it can adjust the indoor humidity and has fire prevention effect. However, the existing plastering plaster has poor bonding force with the base wall, and has poor thermal ...
