Beschreibung
Zusammenfassung:	The invention discloses an insulation board. The insulation board comprises a cement substrate layer, a surface decorating layer and a middle sandwich layer. The middle sandwich layer consists of the following ingredients in part by weight: 30-80 parts of limestone, 10-15 parts of polyurethane, 30-40 parts of aqueous solution, 7-15 parts of petroleum sulfur aluminum, 16-35 parts of curing agents, 20-30 parts of 107 glue, 5-10 parts of coal ash and 2-5 parts of resin powder. Yellow sand is yellow middle and thick sand, and particle diameters of the resin powder are 1mm-3mm. The insulation board not only has a thermal-insulation effect, but also has fireproof and waterproof effects, is high in strength and high in toughness, and can meet requirements of modern buildings. Requirements of external walls of buildings can be met.
