Special additive for machine-made sand plastering mortar and preparation method thereof
The invention relates to the field of buildings, and particularly discloses a special additive for machine-made sand plastering mortar and a preparation method of the special additive. The admixture is prepared from the following raw materials in parts by weight: 12-20 parts of cellulose ether, 1-5 parts of starch ether, 7-12 parts of a water reducing agent, 5-11 parts of a thickening agent, 2-10 parts of an air entraining agent, 1-4 parts of magnesium aluminum silicate, 5-10 parts of a retarder and 40-60 parts of water; the preparation method comprises the following steps: dividing water into two parts, uniformly mixing the water reducing agent with one part of water, then adding the cellulose ether and the starch ether while stirring, and carrying out uniform stirring to obtain a mixture I; adding a thickening agent, an air entraining agent, magnesium aluminum silicate and a retarder into the other part of water under stirring, and carrying out uniform stirring to obtain a mixture II; and stirring the mixture I and the mixture II for 2-3 hours to obtain the admixture. When the admixture is used in the machine-made sand plastering mortar, the construction performance of the machine-made sand plastering mortar can be remarkably improved.
本申请涉及建筑领域，具体公开了一种机制砂抹灰砂浆专用外加剂及其制备方法。外加剂由包含以下重量份的原料制成：纤维素醚12‑20份、淀粉醚1‑5份、减水剂7‑12份、增稠剂5‑11份、引气剂2‑10份、硅酸镁铝1‑4份、缓凝剂5‑10份和水40‑60份；制备方法：将水分成两份，将减水剂与其中一份水混合均匀，随后在搅拌下加入纤维素醚和淀粉醚，搅拌均匀，得到混合物Ⅰ；在搅拌下将增稠剂、引气剂、硅酸镁铝和缓凝剂加入另一份水中，搅拌均匀，得到混合物Ⅱ；将混合物Ⅰ和混合物Ⅱ搅拌2‑3h，即可制得外加剂。将本申请的外加剂用于机制砂抹灰砂浆中，可显著的改善机制砂抹灰砂浆的施工性能。
