Gypsum board and preparation method thereof
The invention provides a gypsum board. The gypsum board contains a carbonate mineral in a trigonal system. The invention also provides a preparation method of the gypsum board. The gypsum board prepared by the embodiment of the invention has the advantages that the carbonate mineral (heavy calcium carbonate or dolomite) in the trigonal system is added and carbonate ions in a sodium chloride like structure of the trigonal system are utilized instead of part of soluble chloride ions, thus reducing the chloride ions which migrate onto the surface of the gypsum board and preventing the phenomenon that adhesion between a gypsum core and corrugation of the gypsum board produced with high chloride desulphurization gypsum in a certain range is poor.
