The invention discloses strong waterproof flame-retardant dry-mixed mortar, which is composed of the following components in percentage by weight: 35-45% of Portland cement, 5-8% of high-alumina cement, 15-22% of fine sand, 3-5% of redispersible latex powder, 0.2-0.5% of hydroxypropyl methyl cellulose, 2-5% of expanded vermiculite powder, 6-10% of fly ash, 8-15% of modified phosphogypsum and the balance of kaolin. According to the invention, high-alumina cement and expanded vermiculite powder are used as a flame-retardant system, so that a good flame-retardant effect is achieved, the dispersion is uniform, and the smoke suppression effect is good; and in order to achieve a strong waterproof effect, Portland cement, high-alumina cement, redispersible latex powder and modified phosphogypsumare used as a gel system, lime powder, ammonium type silica sol and aluminum oxide are used as modifiers for modifying phosphogypsum in the modified phosphogypsum, and the modified phosphogypsum and the cement system are matched with each other, so that a very good waterproof effect is achieved.
本发明公开了一种强防水阻燃干粉砂浆，由如下重量百分比的组分组成：硅酸盐水泥35‑45%、高铝水泥5‑8%、细沙15‑22%、可再分散乳胶粉3‑5%、羟丙基甲基纤维素0.2‑0.5%、膨胀蛭石粉2‑5%、煤粉灰6‑10%、改性磷石膏8‑15%和高岭土余量。其中采用高铝水泥和膨胀蛭石粉作为阻燃体系，不但具有良好的阻燃效果，而且分散均匀，抑烟效果好；而为了达到强防水效果，本发明采用硅酸盐水泥+高铝水泥+可再分散乳胶粉+改性磷石膏作为凝胶体系，其中，改性磷石膏采用石灰粉、铵型硅溶胶和氧化铝作为改性剂对磷石膏进行改性，改性后的磷石膏与水泥体系相互配合，具有非常好的防水效果。
