Abstract

A self-leveling gypsum-based floor-leveling material for building is proportionally prepared from natural anhydrous gypsum, alkaline exciter, acidic exciter, water preserving agent, water decreasing agent and defoamer through grinding anhydrous gypsum, premixing others, mixing the anhydrous gypsum powder with the premixture, and stirring.

Description

technical field [0001] The invention is applied in the technical field of building materials, and in particular relates to a gypsum base ground self-leveling and leveling material and a preparation method thereof. Background technique [0002] Self-leveling is a building floor leveling material that is dry-mixed with inorganic or organic gelling materials, superplasticizers and other additives and fine river sand (quartz sand). When using, just add water according to the specified range of water-cement ratio and mix evenly. After mechanical pumping or manual construction, no manual smoothing is required, and the slurry flows under its own gravity to form a smooth surface. The self-leveling material has a high level of construction, saves labor and time, and is an ideal material for ground leveling construction. [0003] In recent years, there are common reports on the development of self-leveling products for various substrates, but they mainly focus on the development of h...
