Special adhesive mortar for ALC (autoclaved lightweight concrete) board and preparation method of special adhesive mortar
The invention provides special adhesive mortar for an ALC board and a preparation method of the special adhesive mortar, which relate to the field of adhesive mortar. The special adhesive mortar for the ALC board comprises the following components in percentage by mass: 25%-35% of cement, 55%-65% of sand, 5%-10% of fly ash, 2%-4% of soluble rubber powder, 0.1%-0.5% of wood fiber and 0.2%-0.5% of hydroxypropyl methyl cellulose. The preparation method of the special adhesive mortar for the ALC board comprises the following steps of S1, preparing all raw materials according to the proportion, S2, adding soluble rubber powder and hydroxypropyl methyl cellulose into the reaction kettle, stirring for 3-7 minutes, and then filling with a container, S3, putting the cement, the sand and the fly ash into a reaction kettle, and then stirring for 10-15 minutes, and S4, simultaneously adding the material prepared in the step S2 and the wood fiber into the reaction kettle, then stirring and mixing, and stirring for 20-30 minutes to finish the preparation. The designed special adhesive mortar for the ALC board is small in dry shrinkage deformation, has good anti-cracking performance, workability and water-retaining property, has high adhesive force with wall materials or other base materials after being hardened, and can completely prevent cracking of inner and outer walls.
本发明提供一种ALC板专用粘结砂浆及其制作方法，涉及粘结砂浆领域。该ALC板专用粘结砂浆组成成份质量比为：水泥25％‑35％、砂55％‑65％、粉煤灰5％‑10％、可溶性胶粉2％‑4％、木质纤维0.1％‑0.5％、羟丙甲基纤维素0.2％‑0.5％，该ALC板专用粘结砂浆的制作方法，包括以下步骤：S1.按照比例准备好所有原；S2.将可溶性胶粉、羟丙甲基纤维素加入反应釜中，搅拌3‑7min，然后用容器装起；S3.将水泥、砂、粉煤灰放入反应釜中，然后搅拌10‑15min；S4.将S2中制备好的材料和木质纤维同时加入反应釜中，然后搅拌混合，搅拌20‑30min，制备完成。本发明设计的ALC板专用粘结砂浆干缩变形小、具有良好的抗裂性能、和易性和保水性，硬化后与墙体材料或其他基体材料具有较高的粘结力，可以完全防止内外墙的开裂。
