Colored antibacterial gypsum self-leveling mortar and preparation method thereof
The invention relates to colored antibacterial gypsum self-leveling mortar, which is prepared from the following raw materials in percentage by mass: 83 to 88 parts of anhydrite; 5-10 parts of white cement; 5-10 parts of active superfine silver tailings; 0.02 to 0.04 part of methyl cellulose; 0.04 to 0.06 part of a stabilizing agent; 0.08 to 0.1 part of a defoaming agent; 0.13 to 0.15 part of a water reducing agent; 0.7 to 1 part of an exciting agent; 2-3 parts of an inorganic pigment; 0.2 part of a water repellent; and 0.3 to 0.5 part of polyethylene glycol. The colored antibacterial gypsum self-leveling mortar is prepared by adopting an acid-base compound exciting agent to excite the activity of anhydrite, matching with a functional water repellent and an inorganic pigment, adding active superfine silver tailings, and carrying out dry mixing by a mixing machine. After the superfine active silver tailings are subjected to acid modification, silver ions continuously sterilize, and the ground cannot be mildewed; a pouring machine is used for pouring on an uneven base plane after water is added in proportion and evenly stirred, the construction period is short, the hardening speed is high, the surface is smooth, the strength is firm, colors are rich, the water resistance is excellent, and mildew resistance is achieved.
本发明涉及一种彩色抗菌石膏自流平砂浆，包括下述质量百分比的原料：无水硬石膏83‑88份；白水泥5‑10份；活性超细银尾矿5‑10份；甲基纤维素0.02‑0.04份；稳定剂0.04‑0.06份；消泡剂0.08‑0.1份；减水剂0.13‑0.15份；激发剂0.7‑1份；无机颜料2‑3份；憎水剂0.2份；聚乙二醇0.3‑0.5份。本发明是采用酸碱复配激发剂激发无水硬石膏的活性，配以功能性憎水剂及无机颜料，加入活性超细银尾矿经混合机干混而成的一种彩色抗菌石膏自流平砂浆；超细活性银尾矿酸改性后银离子持续杀菌，地面不会发生霉变；使用浇筑机械按比例加水搅拌均匀后在不平的基面上浇筑，施工周期短，硬化速度快，表面光滑且强度坚实，色彩丰富，耐水性优异，抗霉变。
