The invention relates to the technical field of thermal insulation mortar, in particular to lightweight fireproof thermal insulation mortar, which is prepared from the following ingredients in parts by weight: 80 to 100 parts of cement, 60 to 80 parts of modified hollow glass beads, 12 to 30 parts of coal ash, 15 to 30 parts of heavy calcium carbonate powder, 15 to 20 parts of elastic fibers and 2 to 3 parts of auxiliaries. The preparation method of the modified hollow glass beads comprises the following steps: carrying out surface pretreatment on hollow glass beads, grinding scratches on the surfaces of the hollow glass beads, loading ferroferric oxide on the outer walls of the hollow glass beads to obtain ferroferric oxide/hollow glass beads, and finally carrying out spraying treatment to obtain the modified hollow glass beads. A mixture of polyvinyl chloride and chlorinated paraffin is sprayed to the outer side of the ferroferric oxide/hollow glass microbeads, and modified hollow glass microbeads are obtained.The thermal insulation mortar prepared through the method is mainly made of inorganic materials, good in fireproof performance, light in weight, high in strength, excellent in thermal insulation performance and suitable for application and popularization.
本发明涉及保温砂浆技术领域，尤其涉及一种轻质防火保温砂浆，包含以下重量份的组分：水泥80‑100份、改性空心玻璃微珠60‑80份、粉煤灰12‑30份、重钙粉15‑30份、弹性纤维15‑20份和助剂2‑3份，所述改性空心玻璃微珠的制备方法包括以下步骤：对空心玻璃微珠进行表面预处理，在空心玻璃微珠表面磨出划痕，然后在空心玻璃微珠的外壁上负载四氧化三铁，得到四氧化三铁/空心玻璃微珠，最后进行喷涂处理，在四氧化三铁/空心玻璃微珠的外侧喷涂聚氯乙烯与氯化石蜡的混合物，得到改性空心玻璃微珠，通过本发明制备的保温砂浆，其以无机材料为主，防火性能好，且质地轻，强度高，具有优异的保温性能，适合推广使用。
