Abstract

The invention discloses plastering gypsum and a preparation method thereof, and relates to the technical field of gypsum. The plastering gypsum comprises the following raw materials in parts by weight: 55-65 parts of desulfurated gypsum, 40-42 parts of modified rubber powder, 34-36 parts of cement, 24-26 parts of liquid paraffin, 20-22 parts of modified kieselguhr, 18-20 parts of mineral admixture, 14-16 parts of manganese slag, 10-14 parts of an auxiliary agent and 45-65 parts of water. The plastering gypsum is adhered to a base wall well, a coating cannot crack and cannot drop easily, and construction is facilitated.

Description

technical field [0001] The invention relates to the technical field of gypsum, in particular to a plaster for plastering 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 plaster plaster has poor bonding force with the base wall, and the construction operation is cumbersome. Contents of the invention [00...
