The invention discloses thermal insulation plastering mortar prepared from foundry waste sand and a preparation process of the thermal insulation plastering mortar, and belongs to the technical field of mortar. The thermal insulation plastering mortar comprises the following components by weight: 150 to 180 g of foundry waste sand, 2 to 4 g of redispersible rubber powder, 30 to 65 parts of Portland cement, 3 to 7 g of calcium oxide, 5 to 10 g of fly ash, 24 to 30 g of a mineral admixture, 16 to 20 g of vitrified micro bubbles, 19 to 29 g of heat-insulation lightweight aggregate, 5 to 10 g of a binder and 3 to 9 g of anti-crack fibers. According to the thermal insulation plastering mortar prepared from the foundry waste sand and the preparation process of the thermal insulation plastering mortar, the bonding strength and the crack resistance of the mortar are greatly improved, a formed plastering layer has good durability and thermal insulation capacity, the service life of an external thermal insulation system of an external wall can be prolonged, and casting waste ash and waste sand are utilized at the same time in the preparation process.
本发明公开了一种利用铸造废砂制作保温抹面砂浆及其制作工艺，属于砂浆技术领域，包括以下重量的组分制成：铸造废砂的含量为150‑180g、可再分散胶粉的含量为2‑4g、硅酸盐水泥30‑65份、氧化钙的含量为3‑7g、粉煤灰的含量为5‑10g、矿物掺合料含量为24‑30g、玻化微珠含量为16‑20g、隔热轻骨料含量为19‑29g、粘结剂含量为5‑10g和抗裂纤维含量为3‑9g。本发明提出的一种利用铸造废砂制作保温抹面砂浆及其制作工艺，高大大提高砂浆的粘结强度和抗裂性能，其所形成的抹面层具有良好的耐久性能和保温能力，能够延长外墙外保温系统的使用寿命，并且在制备过程中还将铸造废灰和废砂同时利用。
