[0002] Polystyrene foam board, also known as foam board and EPS board, is a white object formed by heating and molding expandable polystyrene beads containing a volatile liquid foaming agent in a mold. It has a fine and closed structure and is mainly used for building walls, layer insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration carving, and other purposes. However, general polystyrene foam boards have weak functionality and are not fire-resistant, easily burning when exposed to open flames. Once ignited, it is difficult to extinguish, causing significant losses. The structural strength of the foam board is not high, it is easy to break, the service life is short, and the use cost is high, which affects the use of the foam board.
