Preparation method of waterproof plastering mortar and plastering mortar
The invention provides a preparation method of waterproof plastering mortar and the plastering mortar. In the preparation process of the plastering mortar, the raw materials comprise: aggregate consisting of 40-140-mesh sand and 40-140-mesh zeolite particles; an aggregate surface treating agent; ordinary Portland cement; a water-retaining agent: cellulose ether and/or water-absorbent resin; a strength agent; an early strength agent; a thixotropic agent; waterproof and hydrophobic powder; heavy calcium powder; pP fibers; the waterproof plastering mortar is prepared from the following components in percentage by weight: 46.6 to 66.0 percent of aggregate subjected to hydrophobic treatment, 0.15 to 0.2 percent of cellulose ether, 0.02 to 0.05 percent of water-absorbent resin, 2.5 to 3.5 percent of reinforcing agent, 0.3 to 0.5 percent of early strength agent, 0.02 to 0.05 percent of thixotropic agent, 2 to 4 percent of waterproof hydrophobic powder prepared in the step (2), 4 to 10 percent of heavy calcium powder and 0.1 percent of PP (Propene Polymer) fiber. According to the invention, by adding the specific aggregate subjected to hydrophobic treatment and the waterproof and hydrophobic powder, the technical defects that the compactness, the anti-permeability effect, the water absorption rate, the thermal insulation property and the like of the waterproof plastering mortar in the prior art cannot be balanced are finally solved.
本发明提供一种防水抹面砂浆的制备方法及抹面砂浆。所述抹面砂浆制备过程中，原料包括：骨料：由40‑140目砂子和沸石颗粒40‑140目组成；骨料表面处理剂；普通硅酸盐水泥；保水剂：纤维素醚和/或吸水树脂；强剂；早强剂；触变剂；防水憎水粉；重钙粉；PP纤维；防水型抹面砂浆包括：憎水处理后的骨料占46.6‑66.0％、纤维素醚占0.15‑0.2％、吸水树脂占0.02‑0.05％、增强剂占2.5‑3.5％、早强剂占0.3‑0.5％、触变剂占0.02‑0.05％、步骤(2)制备的防水憎水粉2‑4％、重钙粉4‑10％、PP纤维0.1％。本发明通过特定的憎水处理的骨料以及防水憎水粉的加入，最终实现了解决现有技术中防水型抹面砂浆存在的无法平衡密实度、抗渗效果、吸水率以及保温性能等的技术缺陷。
