Plastering anti-crack waterproof mortar and preparation method thereof
The invention relates to the field of concrete, and particularly discloses plastering anti-crack waterproof mortar and a preparation method thereof. The mortar comprises 280-314 parts of cement; 1100-1320 parts of sand; 66-78 parts of stone powder; 6.5-8.1 parts of an admixture; 0.8-1.3 parts of polypropylene anti-cracking fibers; 8.9-11.7 parts of a waterproof agent; 36-48 parts of coumarone resin; 28-42 parts of aluminum dihydrogen phosphate; 185-215 parts of water; the preparation method comprises the following steps: sequentially mixing and stirring the raw materials of the mortar to obtain the mortar. The coumarone resin is cracked and shrunk under the high-temperature condition, so that the high-temperature expansion efficiency of the plastering mortar is relieved, the high-temperature bonding strength of the aluminum dihydrogen phosphate is improved, and the phenomena of bulging and cracking occurring after a mortar fire disaster are improved.
本申请涉及混凝土的领域，具体公开了一种抹灰抗裂防水砂浆及其制备方法。砂浆包括水泥：280份‑314份；砂：1100份‑1320份；石粉：66份‑78份；外加剂：6.5份‑8.1份；聚丙烯抗裂纤维：0.8份‑1.3份；防水剂：8.9份‑11.7份；古马隆树脂：36份‑48份；磷酸二氢铝：28份‑42份；水：185份‑215份；其制备方法为：将砂浆各原料依次混合搅拌后，即得砂浆。本申请利用古马隆树脂在高温条件下裂解收缩，以缓和抹灰砂浆高温膨胀效率，提高磷酸二氢铝的高温粘结强度，改善砂浆火灾后出现的鼓包、开裂现象。
