Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flame-retardant and heat-preserving composite sandwich panel. Background technique [0002] Polymer foam materials have the advantages of light weight, high specific strength, chemical corrosion resistance, thermal insulation, sound absorption and noise reduction, shock absorption, softness, insulation, easy processing and high cost performance. At present, the most important polymer foam materials include expandable polystyrene foam, extruded polystyrene foam, polyurethane foam and polyvinyl chloride foam. Expandable polystyrene foam is a foam material formed by bonding together hard closed-cell foam particles. It has the advantages of low density, water resistance, sound absorption and heat insulation, and low price. It is the largest foam variety in my country. , At present, it has been widely used in the fields of building wall, roof insulation, refrigeration, ve...
