Abstract

The invention discloses a waterproof plastering gypsum, and belongs to the technical field of plastering gypsums. The plastering gypsum comprises the following raw materials in parts by weight: 60-70 parts of desulphurization gypsum, 25-30 parts of silica sand, 14-18 parts of calcium carbonate, 13-15 parts of cement, 8-10 parts of polytrimethylene terephthalate fiber, 10-12 parts of ceramic fiber, 7-9 parts of modified magnesium hydroxide, 6-8 parts of kieselguhr, 5-7 parts of starch, 1-3 parts of hydroxy propyl methyl cellulose, 3-5 parts of an organosilicone water repellent, 1-2 parts of a retarder, 2-4 parts of an antibacterial agent, 14-16 parts of an acrylic emulsion and 5-15 parts of water. The invention further discloses a preparation method of the waterproof plastering gypsum, the preparation is simple, and the waterproof plastering gypsum has excellent waterproof, fireproof and high temperature resistant capabilities after being solidified.

Description

technical field [0001] The invention relates to the technical field of plaster plaster, in particular to a waterproof plaster plaster and a preparation method thereof. Background technique [0002] Gypsum plaster is an ancient building material and belongs to one of the three traditional inorganic cementitious materials. 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 t...
