Abstract

The invention discloses composite thermal-insulation mortar and a preparation method thereof. The composite thermal-insulation mortar comprises the following raw materials in parts by weight: 100-200 parts of ordinary Portland cement, 80-100 parts of polyphenyl granules, 60-80 parts of expanded perlite, 35-50 parts of nano ceramics, 15-25 parts of polypropylene fibers, 2-5 parts of an air entraining agent, 6-8 parts of a leveling agent, and 8-15 parts of redispersible emulsion powder. The expanded perlite and the polyphenyl granules are simultaneously used as lightweight aggregate granules of the thermal-insulation mortar, and the prepared composite thermal-insulation mortar has excellent thermal-insulation property and fire resistance. In addition, owing to addition of the nano ceramics, the problem that the expanded perlite absorbs water is solved, further, the problem of poor fire resistance of the polyphenyl granules is solved, and therefore, the composite thermal-insulation mortar has excellent overall performance.

Description

technical field [0001] The invention belongs to the technical field of building mortar, and in particular relates to a composite thermal insulation mortar and a preparation method thereof. Background technique [0002] At present, domestic wall insulation materials are mostly organic materials, such as polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane, polystyrene particle insulation mortar, etc. It has good heat preservation effect in use, but there is a problem of being easy to burn, and the fire protection level is poor. [0003] Compared with organic thermal insulation materials, the expanded pearl thermal insulation mortar in inorganic thermal insulation mortar has the characteristics of higher strength, better durability and fire resistance, and is a building material with better comprehensive performance. However, expanded perlite has high water absorption. After absorbing water, it will not only reduce the strength of the material, but also gre...
