Phosphogypsum-based binding gypsum

Номер: CN116514504A
Автор: RAN JINGYU, ZHANG HONGBING, WANG WEI, THE INVENTOR HAS WAIVED THE RIGHT TO BE MENTIONED
Принадлежит:

The invention provides ardealite-based bonding gypsum. The ardealite-based bonding gypsum is prepared from the following components: phosphorus building gypsum powder, fly ash, modified bentonite, coarse whiting, an anti-seepage material, a gypsum retarder, a water-retaining agent and an inorganic binder. By adding the anti-seepage material prepared from the high-molecular polymer fatty acid salt, the calcium carbonate, the polyvinyl acetate calcium carbonate, the phosphate and the compound emulsifier, molecular gaps between an ardealite base and a concrete base surface are greatly reduced, and a multi-layer permanent waterproof and anti-corrosion whole which is not easy to damage is formed on the base surface; in addition, the gypsum retarder is matched, so that good bonding strength is achieved, the bonding strength of a base plane is guaranteed, and the phenomena of masonry cracks, hollowing and falling of a decorative layer and the like cannot occur after long-term use.
