High-water-resistance ardealite self-leveling mortar and preparation method thereof
The invention discloses ardealite self-leveling mortar with high water resistance. The ardealite self-leveling mortar is characterized by being prepared from the following components in parts by weight: 80 to 90 parts of ardealite, 2 to 5 parts of cement, 1 to 3 parts of mineral powder, 0.4 to 0.8 part of ethyl cellulose, 6 to 8 parts of nano silicon dioxide, 12 to 14 parts of microcapsules, 1.6 to 1.8 parts of a water reducing agent, 0.1 to 0.3 part of a de-foaming agent, 0.08 to 0.12 part of a retarder and 26 to 30 parts of water. According to the waterproof mortar, an insoluble hydration product formed by cement and mineral powder in a mixture, ethyl cellulose and nano silicon dioxide can form a network structure to fill tiny pores in the mortar to prevent water permeation and enhance water resistance, finally, the waterproof agent is packaged in microcapsules prepared from gelatin, and the microcapsules can be crushed and dissolved when being in contact with water, so that the waterproof mortar has a waterproof effect. The waterproof agent is released to fill pores and cracks to form a waterproof barrier, so that the water resistance of the gypsum mortar is improved.
本发明公开了一种高耐水磷石膏自流平砂浆，其特征在于组成按重量份数计如下：磷石膏80‑90份，水泥2‑5份，矿粉1‑3份，乙基纤维素0.4‑0.8份，纳米二氧化硅6‑8份，微胶囊12‑14份，减水剂1.6‑1.8份，消泡剂0.1‑0.3份，缓凝剂0.08‑0.12份，水26‑30份；本发明中水泥与矿粉在混合物中形成的难溶性水化产物，乙基纤维素与纳米二氧化硅能够形成网络结构填充砂浆中的微小孔隙阻止水分渗透增强耐水性，最后通过将防水剂封装于明胶制备的微胶囊中，当与水接触时会被压破并溶解，释放防水剂填充孔隙和裂缝，形成防水屏障，提高石膏砂浆的耐水性。
