Anti-crack plastering mortar and preparation method thereof
The invention relates to the field of mortar, and particularly discloses anti-crack plastering mortar and a preparation method, the mortar comprises the following raw materials by weight: 70-100 parts of cement, 5-9 parts of sodium alginate, 3-7 parts of latex powder, 100-155 parts of machine-made sand, 80-180 parts of gypsum, 10-25 parts of diatomite, 3-6 parts of fly ash, 1-3 parts of an auxiliary agent, and 15-35 parts of anti-crack fiber. The preparation method comprises the following steps: gypsum pretreatment: homogenizing sodium alginate and gypsum under the condition of ultrasonic coupling mechanical stirring; pretreatment of the machine-made sand: dissolving an auxiliary agent in water to form an auxiliary agent solution, and mixing and grinding the latex powder and the machine-made sand; mixing: uniformly mixing the cement, the pretreated gypsum, the machine-made sand, the diatomite, the fly ash and the anti-cracking fiber, adding a proper amount of water, and uniformly stirring. The anti-cracking plastering mortar has the advantages that the anti-cracking performance of the plastering mortar is improved, and the bonding strength of the plastering mortar and a concrete base layer is improved.
本申请涉及砂浆领域，具体公开了一种抗裂抹灰砂浆及制备方法，砂浆包括以下重量份的原料：水泥70‑100份，海藻酸钠5‑9份，乳胶粉3‑7份，机制砂100‑155份，石膏80‑180份，硅藻土10‑25份，粉煤灰3‑6份，助剂1‑3份，抗裂纤维15‑35份。其制备方法包括以下步骤：石膏预处理：将海藻酸钠与石膏在超声波耦合机械搅拌的条件下进行均质；机制砂预处理：将助剂溶于水形成助剂溶液、乳胶粉与机制砂进行混合研磨；混料：将水泥、经过预处理的石膏和机制砂、硅藻土、粉煤灰、抗裂纤维混合均匀，加入适量水搅拌均匀。本申请具有提高抹灰砂浆的抗裂性能以及改善与混凝土基层的粘结强度的优点。
