Abstract

The invention relates to a light desulfurized plastering gypsum, an auxiliary agent and a preparation method thereof, and relates to the field of plastering gypsum. The auxiliary agent of light desulfurization plastering gypsum includes the following raw materials by weight: 3-10 weight parts of heavy calcium, 5-10 weight parts of aging stabilizer and 0.1-0.3 weight parts of anti-cracking and crystallizing agent. The additive of the present invention can effectively accelerate the aging of gypsum by adding an aging stabilizer, an anti-cracking and crystallizing agent, etc., and is formulated with other additives (light fillers, etc.) to make the unstable and uneven gypsum phase rapidly It tends to be stable and uniform, and reduces the water demand, improves the strength, and stabilizes the setting time, which prevents and avoids the risk of plastering gypsum cracking at all stages.

Description

technical field [0001] The invention relates to the field of plastering gypsum, in particular to an auxiliary agent for light desulfurization plastering gypsum, light desulfurization plastering gypsum, and a preparation method of light desulfurizing plastering gypsum. Background technique [0002] Since 2016, with the vigorous implementation of national environmental protection policies across the country, the prices of building materials such as cement, natural gypsum, and sand have skyrocketed, and a large number of factories have been shut down. Raw materials, light plastering gypsum with no sand or only a very small amount of sand are added, showing great advantages. [0003] In addition, with the advent of the era of hardcover houses, the requirements for the construction period are very strict. If developers want to achieve high capital turnover, they can only speed up the progress of construction. Lightweight plastering gypsum has high construction efficiency, no main...
