Abstract

The invention discloses an inorganic thermal insulation material for a wall. The inorganic thermal insulation material comprises the following components in parts by mass: 35-60 parts of basalt sand,5-8 parts of aluminum hydroxide, 8-12 parts of nanoparticles, 5-10 parts of a binder, 3-8 parts of dustproof oil, 5-10 parts of a water repellent, 3-15 parts of expanded perlite, 5-12 parts of rigid foam polyurethane, 4-8 parts of polymer bonding mortar, 3-10 parts of thermal insulation mortar, 4-12 parts of polymer plastering anti-crack mortar and 10-15 parts of water. According to the inorganicthermal insulation material disclosed by the invention, the nanoparticles are added into the raw materials, so the loading capacity and the surface area of a traditional inorganic thermal insulation material for a wall are increased; and besides, the rigid foam polyurethane and rock wool are compounded together, and experiments show that a rock wool material added with the rigid foam polyurethanecan greatly reduce the K value of the heat transfer coefficient of an outer wall, and meets the technical indexes of ultralow-energy-consumption buildings.

Description

technical field

[0001] The invention relates to a thermal insulation material, in particular to an inorganic wall thermal insulation material, which belongs to the application field of thermal insulation materials. Background technique

[0002] Wall thermal insulation materials can improve the thermal insulation performance of the wall. They are divided into organic thermal insulation materials, inorganic thermal insulation materials and composite thermal insulation materials. Inorganic thermal insulation materials generally use perlite cement board, rock wool board, foam cement board, etc. , Inorganic thermal insulation materials have the advantages of light weight, good thermal insulation effect, and rich raw materials. However, due to their light weight, inorganic thermal insulation materials have a small lifting capacity, and because most of the wall glue used in inorganic thermal insulation materials is 107 glue or 801 Construction glue, because it contains harmful chem...
