Various types and status quo of thermal insulation core materials for color steel sandwich panel

The thermal insulation, heat insulation, sound absorption and other properties of the color steel sandwich panel mainly depend on its core material - thermal insulation material. This material should not only have good thermal insulation, but also need to have sufficient strength and rigidity, as well as good adhesion with the color steel plate. Only in this way, the combined composite board can withstand the design load and meet the functional requirements of the building.
Color steel sandwich panel core materials can be divided into two categories according to the chemical composition of their products, namely, one is organic chemical foam materials, such as polyurethane foam, polystyrene foam, phenolic foam, melamine Styrofoam etc. The other type is inorganic fiber materials, such as rock wool board, mineral wool board, glass wool board, etc.
At present, the most widely used color steel sandwich panel insulation core materials for domestic color steel sandwich panel manufacturers are polystyrene sandwich panel (EPS sandwich panel), rigid polyurethane sandwich panel (PU sandwich panel) board), rock wool sandwich panel is RW sandwich panel. However, organic materials such as polyurethane and polystyrene have low heat-resistance temperature, are easy to burn in case of fire, and are easy to generate toxic gas, which has become one of the main factors of fire accidents.
