Abstract

The invention discloses waterproof plastering gypsum and a production method thereof, which relate to the technical field of a plastering material. The waterproof plastering gypsum comprises the following raw materials by parts: 55-65 parts of desulfurized gypsum, 42-44 parts of cement, 38-40 parts of modified kaolin, 32-33 parts of fireproof particles, 26-28 parts of anhydrous magnesium chloride, 24-26 parts of a crystal growth stimulator, 21-23 parts of floating beads, 18-19 parts of an organosilicon water repellent, 15-16 parts of an auxiliary agent, and 65-70 parts of water. The waterproof plastering gypsum has excellent waterproof performance, is not easily damped and shed, and has high stability.

Description

technical field [0001] The invention relates to the technical field of plastering materials, in particular to a waterproof plastering plaster and a preparation method thereof. Background technique [0002] my country has a long history of using gypsum cementitious materials, but the scope of application is limited. With the improvement of living standards, people's awareness and requirements for building materials such as energy saving, safety and non-toxicity have increased, and gypsum materials have a series of technical advantages. , making it an energy-saving green material that is respected internationally. The gypsum plastering layer hardens quickly, and the surface layer can be constructed within 1h-2h after the bottom layer is completed, which greatly shortens the construction period. After construction, no maintenance is required, which is conducive to the protection of the finished product. Plaster plaster can be well bonded to any base material, and is not limited...
