Quick-setting waterproof ardealite material as well as preparation method and application thereof
The invention discloses a quick-setting waterproof ardealite material as well as a preparation method and application thereof. The quick-setting waterproof ardealite material is prepared from the following components in parts by weight: 900-1100 parts of ardealite, 350-450 parts of water, 50-150 parts of sawdust, 1-3 parts of a water reducing agent and 8-12 parts of a waterproof agent. The ardealite is dried ardealite obtained by drying treatment, and the drying temperature is 100-115 DEG C. According to the invention, the coupling effect between the dried phosphogypsum components is fully utilized, the reaction rate with water is promoted, and a quick-setting phosphogypsum material without adding a coagulant is researched and developed. Through the coupling effect of the waterproof agent and the water reducing agent, the amount of water reacting with phosphogypsum is greatly reduced, and the waterproof quick-setting phosphogypsum material with high early strength is obtained. The wood chips are added, so that the density of the material is greatly reduced, and the fracture resistance of the material is enhanced. The method disclosed by the invention well solves the problem of environmental pollution caused by an industrial byproduct, namely ardealite in the current phosphoric acid production, and greatly promotes the resource reutilization of the ardealite in the field of building materials.
本发明公开了一种速凝防水磷石膏材料及其制备方法和应用，由按重量份计的如下组分制备而成：磷石膏900‑1100份，水350‑450份，木屑50‑150份，减水剂1‑3份，防水剂8‑12份。所述磷石膏是经过烘干处理得到的烘干磷石膏，烘干温度为100℃‑115℃。本发明充分利用烘干磷石膏组分之间的耦合作用，促进与水反应的速率，研发出一款无需添加促凝剂的速凝的磷石膏材料。本发明通过防水剂与减水剂的耦合作用，大幅减少与磷石膏反应的水量，得到早期强度高的防水速凝磷石膏材料。木屑的加入在大幅降低材料的密度的同时，增强其抗折性能。本发明很好地解决当前磷酸生产时的工业副产品‑磷石膏造成的环境污染问题，大大促进磷石膏在建筑材料领域的资源化再利用。
