Abstract

The invention belongs to the technical field of novel wall materials, and relates to a radiation-proof composite insulation board which is produced from raw materials of expanded perlite, water glass, cement, carbon nanotubes and an aluminum alloy grid. The radiation-proof composite insulation board doped with the carbon nano tubes is prepared from the following raw materials in parts by weight: 50 parts of expanded perlite, 60-100 parts of water glass, 60-100 parts of cement and 0.1-1.0 part of carbon nanotubes. The radiation-proof composite insulation board doped with the carbon nano tubes has a radiation-proof function on the basis of insulation and fire protection, is suitable for insulation and radiation protection of an external wall of a building, and is a wall insulation material with a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and relates to a radiation-proof composite thermal insulation board produced from expanded perlite, water glass, cement, carbon nanotubes and aluminum alloy grids as raw materials. Background technique [0002] With the rapid development of economy and the sharp increase of energy consumption, wall insulation materials have been developed rapidly in our country. At present, organic thermal insulation materials are mostly used in building exterior wall enclosure structures, but such thermal insulation materials are extremely flammable and produce toxic gases when burned. Inorganic thermal insulation materials have excellent fire resistance, good aging resistance, and high bonding strength with surface materials, and have become a research hotspot in the field of building thermal insulation. In today's society, electromagnetic rays are widely used in various fields such as military affa...
