Abstract

The invention discloses a waterproof plastering gypsum and a preparation method thereof, and relates to the technical field of plastering gypsum. The waterproof plastering gypsum comprises the following raw materials in parts by weight: 85-95 parts of natural gypsum, 25-35 parts of mineral ash, 20-25 parts of natural stone powder, 20-25 parts of an aldehyde remover, 15-20 parts of an assistant, 10-15 parts of vitrified micro-bubbles and 90-120 parts of water. According to the invention, the problems that the existing plastering gypsum is poor in water resistance and easy to mildew and fall offdue to damp are solved.

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] As one of the three traditional inorganic cementitious materials, gypsum has a wide range of applications. At present, as a green and environmentally friendly building material, it is becoming more and more popular in plastering wall materials. During the hydration process, a large number of voids are formed to provide opportunities for water attack, and the plaster absorbs too much water, which will cause it to mold and fall off. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof plaster and its preparation method, which solves the problems that the current plaster has poor water resistance and is easy to mold and fall off when it is damp. [0004] The present invention provides the following technical scheme: a waterproof plaste...
