Modified ardealite with mildew-proof and antibacterial properties and preparation method of modified ardealite
The invention discloses modified phosphogypsum with mildew-proof and antibacterial properties and a preparation method thereof, and belongs to the field of phosphogypsum mildew-proof and antibacterial treatment. The modified ardealite with mildew-proof and antibacterial properties is prepared from the following raw materials in percentage by mass: 0.2 to 0.5 percent of water-soluble quaternary ammonium salt bacteriostatic agent, 14 to 24 percent of inorganic alkaline material, 46 to 56 percent of ardealite powder and 29.8 to 35.8 percent of water, wherein the water-soluble quaternary ammonium salt bacteriostatic agent is prepared from the following components in percentage by mass: 0.1 to 0.3 percent of benzalkonium chloride and 0.1 to 0.3 percent of hexadecyl trimethyl ammonium bromide; the inorganic alkaline material is prepared from the following components in percentage by mass: 5 to 20 percent of P.O 42.5 ordinary Portland cement and 3 to 9 percent of Ca (OH) 2; the dosage of quaternary ammonium salt bacteriostatic agents and inorganic alkaline materials used for achieving the same anti-mildew effect through original single-doping modification is reduced through the synergistic effect, the cost needed by phosphogypsum resourceful treatment is reduced, and meanwhile the optimal anti-mildew effect can be achieved on the premise that the strength of phosphogypsum is not affected.
本发明公开一种具备防霉抗菌性能的改性磷石膏及其制备方法，属于磷石膏防霉抗菌处理领域；一种具备防霉抗菌性能的改性磷石膏包括以下质量百分比的原料：0.2％‑0.5％的水溶性季铵盐类抑菌剂、14％‑24％的无机碱性材料、46％‑56％的磷石膏粉末以及29.8％‑35.8％的水；其中水溶性季铵盐类抑菌剂中包括：0.1％‑0.3％质量百分比的苯扎氯铵和0.1％‑0.3％质量百分比的十六烷基三甲基溴化铵；无机碱性材料中包括：5％‑20％质量百分比的P·O 42.5普通硅酸盐水泥和3％‑9％质量百分比的Ca(OH)2；通过协同作用降低原本单掺改性达到同等抗霉效果所用的季铵盐类抑菌剂和无机碱性材料用量，减少磷石膏资源化处理所需成本，同时还能在不影响磷石膏强度的前提下达到最优的抗霉效果。
