High-water-resistance phosphogypsum self-leveling mortar and preparation method thereof
The invention discloses ardealite self-leveling mortar with high water resistance and a preparation method of the ardealite self-leveling mortar. According to the gypsum self-leveling mortar disclosed by the invention, the phosphogypsum, the sulphoaluminate cement, the ash calcium and the ground calcium carbonate are premixed, all inorganic components are distributed more uniformly, the powder water reducing agent, the dispersible latex powder, the gypsum-grade coagulant, the defoaming agent, the cellulose ether and the rheological agent are premixed, and all additive components can be weighed more accurately, so that the stability of the performance of the gypsum self-leveling mortar is improved; the water-soluble hydantoin epoxy resin is firstly added into the mixture A and the mixture B, then the composite waterproof agent is added, finally, the high-water-resistance phosphogypsum self-leveling mortar is obtained, polyvinyl alcohol and stearic acid or stearic acid salt are emulsified to generate an emulsifier, the water absorption rate of a gypsum material is reduced, in addition, the generated emulsion has hydrophobicity, and the water resistance of the gypsum material can be remarkably improved; and finally, the strength of the gypsum is improved by an alcohol amine substance, the compactness of the gypsum is further improved, the porosity is reduced, and the water resistance is improved.
本发明公开了一种高耐水性磷石膏自流平砂浆及其制备方法。本发明中，将磷石膏、硫铝酸盐水泥、灰钙、重钙预先混合，各无机组分间分布更均匀，将粉体减水剂、可分散乳胶粉、石膏级凝剂、消泡剂、纤维素醚、流变剂预先混合，各种外加剂组分称量能够更加精准，提高了石膏自流平砂浆性能的稳定性，将混合物A和B先加入水溶性海因环氧树脂，再加入复合防水剂，最终得到高耐水性磷石膏自流平砂浆，采用聚乙烯醇和硬酯酸或硬酯酸盐乳化生成乳化剂，降低石膏材料的吸水率，此外，生成的乳液具有憎水性，可显著提高其耐水性；最后，醇胺类物质提高石膏强度，进一步提高石膏的密实性，降低孔隙率，从而提高其耐水性。
