Water-resistant phosphogypsum board and preparation method thereof
The invention discloses a water-resistant phosphogypsum board, which comprises the following components in parts by mass: 400-600 parts of phosphogypsum clinker, 0.5-1.5 parts of rubber powder, 0.05-2parts of organic silicone oil, 2-9 parts of white cement, 2.5-5 parts of modified starch, 0.2-0.5 part of a foaming agent, 0.04-4 parts of a water reducing enhancer, and 200-380 parts of water. According to the invention, the water-resistant phosphogypsum board can effectively remove the influence of water-soluble phosphorus in phosphogypsum on the hydrophobic property of organic silicone oil, sothat the water absorption rate of the phosphogypsum board is not more than 10% after the phosphogypsum board is soaked in water for 2 hours; and after the white cement is doped into the phosphogypsumclinker, the workability of the phosphogypsum clinker and the white cement is good, the problems of bleeding, bulging and the like are avoided when the phosphogypsum clinker is in preparation of phosphogypsum boards, and the strength of the phosphogypsum boards can be improved.
本发明公开了一种耐水磷石膏板，包括以下组分，所述各组分的含量以质量比表示如下：磷石膏熟料400‑600质量份；胶粉0.5‑1.5质量份；有机硅油0.05‑2质量份；白水泥2‑9质量份；改性淀粉2.5‑5质量份；发泡剂0.2‑0.5质量份；减水增强剂0.04‑4质量份；水200‑380质量份。该耐水磷石膏板能够保证有效去除磷石膏中水溶磷对有机硅油的疏水性能的影响，从而保证了磷石膏板浸水2小时后，其吸水率不大于10％。同时，磷石膏熟料中掺入白水泥后，两者的和易性好，用于磷石膏板制备时，不会出现泌水，鼓包等问题，并能提高磷石膏板的强度。
