Gypsum-based polymer waterproof mortar
The invention discloses gypsum-based polymer waterproof mortar, which is prepared from the following ingredients in parts by weight: 41.6 to 60 parts of phosphogypsum, 4.4 to 6 parts of building gypsum, 30 to 50 parts of slag, 4 parts of cement, 0.15 to 0.30 part of K2SO4, 33 to 39 parts of water, 150 to 225 parts of fine sand, 0 to 5 parts of latex powder, 0 to 4.5 parts of tung oil or 0 to 1.5 parts of calcium stearate, 5 to 10 parts of nanometer magnesium oxide, 5 to 10 parts of coal ash, 0.07 to 0.13 part of water reducing agents and 0 to 0.15 part of defoaming agents. The water-binder ratio is 0.33 to 0.39. The ardealite used in the invention is dehydrated by heat treatment, i.e., is calcined at a constant temperature of 820 DEG C for 0-2 hours, so that soluble phosphorus, organic matters and other impurities can be removed, and the performance of the ardealite is stable.
本发明公开了一种石膏基聚合物防水砂浆，包括如下重量份的组份：41.6‑60份磷石膏、4.4‑6份建筑石膏、30‑50份矿渣、4份水泥、0.15‑0.30份K2SO4、水33‑39份、细砂150‑225份、乳胶粉0‑5份、桐油0‑4.5份或硬脂酸钙0‑1.5份、纳米氧化镁5‑10份，粉煤灰5‑10份、减水剂0.07‑0.13份与消泡剂0‑0.15份，其中，水胶比为0.33‑0.39。本发明用的磷石膏经过热处理脱水，即820℃恒温煅烧0～2h，可除去可溶性磷、有机物等杂质，使其性能稳定。
