Problems solved by technology

[0002] At present, there are several types of insulation boards for external walls in my country, such as polystyrene foam boards, gypsum boards, cement boards, and expanded perlite boards. It meets the performance requirements of the building envelope, so now the composite material insulation board is paid more attention and has been developed rapidly. The composite material insulation board is a new type of external wall insulation board with multi-directional excellent performance, but the technical development is relatively not. Too mature, the production process is complicated and diverse, and the properties such as compressive strength and flexural strength are not up to the requirements for use
