Phosphogypsum base material marble-imitated floor tile and preparation method thereof
The invention discloses a phosphogypsum base material marble-imitated floor tile and a preparation method thereof. In parts by weight, the floor tile is prepared from 50-80 parts of phosphogypsum, 20-40 parts of yellow phosphorus slag, 0.1-2 parts of fiber and 1-8 parts of quicklime. Phosphorus slag powder which is good in fluidity and uniform in particle can be prepared by mixing the yellow phosphorus slag with the phosphogypsum, stirred and reacted at 90-100 DEG C, and then ground. The quicklime, the fiber and the phosphorus slag powder are mixed under a certain temperature and a stirring speed and are subjected to aging treatment, so as to significantly shorten aging time; through a hydration reaction, the phosphorus slag powder can generate a main product, namely ettringite crystal; the intensity and the water resistance of the phosphogypsum base material marble-imitated floor tile are significantly improved; and the content of soluble impurities in the phosphogypsum is reduced and the coagulation property of the phosphogypsum base material marble-imitated floor tile is greatly improved.
