Problems solved by technology

[0003] However, plastering gypsum sometimes has quality problems such as low strength and falling powder in practical applications. The strength of domestic plastering gypsum varies greatly, and sometimes powder falling occurs, and even the strength is too low to be used as architectural decorative coatings and Base layer for pasting colorful wallpaper
In the home decoration project, the low-strength plastering gypsum should be shoveled off, which wastes manpower and time, produces dust and construction waste, and pollutes the environment

preparation example Construction

[0052] The second aspect of the present invention provides a method for preparing a gypsum-based lightweight plastering material, which at least includes the following steps: adding each component into a mixer and mixing well and uniformly.

[0053] In a preferred embodiment, the preparation method of the gypsum-based lightweight plastering material at least includes the following steps: first, the mixture is pre-prepared by weight, and then the gypsum powder, alkaline agent, water-retaining Add the agent, mixture and retarder into the mixer and stir evenly, then add vitrified microbeads and mix well, then enter the finished product warehouse.

Embodiment 1

[0057] Embodiment 1 of the present invention provides a gypsum-based lightweight plastering material. In parts by weight, the preparation raw materials include: 90 parts of gypsum powder, 1 part of alkaline agent, 0.15 part of water-retaining agent, 0.2 part of mixture, 0.1 part of Retarder, 11 parts vitrified microspheres.

[0058] The gypsum powder is β-semi-hydrated building gypsum; the preparation steps of the β-semi-hydrated building gypsum are: the desulfurized gypsum obtained by the wet desulfurization process of a thermal power plant is passed through a vibrating screen to remove larger pieces of gypsum and its impurities, and sent to Enter the indirect steam rotary kiln. The indirect steam rotary kiln uses 1.8MPa saturated steam as the heat source, and transfers the heat of the steam to the desulfurization gypsum through the indirect heat transfer method. After the desulfurization gypsum absorbs the heat, the temperature rises. free water; when the calcination tempera...

Abstract

The invention relates to the technical field of buildings, and particularly provides a gypsum-based light plastering material and a preparation method thereof. The first aspect of the invention provides a gypsum-based light plastering material which at least comprises the preparation raw materials in parts by weight: 80-95 parts of gypsum powder, 0.5-2 parts of an alkaline agent, 0.1-0.2 part of awater-retaining agent, 0.1-0.3 part of a mixture, 0.05-0.2 part of a retarder and 0-20 parts of glass microbeads.

Description

technical field [0001] The invention relates to the technical field of construction, and more specifically, the invention provides a gypsum-based lightweight plastering material and a preparation method thereof. Background technique [0002] With the development of the construction industry, the building frame structure has become a trend. With the passage of time and the improvement of people's housing requirements, hollowing and cracking are difficult to control. Plastering plaster just makes up for these shortcomings. Plastering gypsum is a high-efficiency and energy-saving plastering material for interior walls and ceilings of buildings, which is processed with gypsum as the main cementitious material, sand, certain admixtures and special compound additives. It is widely used for interior walls and roofs. Leveling and decoration. In modern construction projects, plastering gypsum mainly replaces plastering materials such as cement, lime mortar and clay mortar, and is su...
