Beschreibung
Zusammenfassung:	The invention relates to a hard foam polyurethane phase-transition heat preservation composite board. The hard foam polyurethane phase-transition heat preservation composite board comprises a hard foam polyurethane heat preservation layer and a phase-transition composite layer, wherein the hard foam polyurethane heat preservation layer served as a core material is coated by the phase-transition composite layer; and the phase-transition composite layer comprises a phase-transition composite sheet precast in a production line and phase-transition mortar used for spraying and scraping. The hard foam polyurethane phase-transition heat preservation composite board ingeniously combines thermal-insulation heat preservation with phase-transition heat preservation, has higher system thermal resistance compared with the conventional hard foam polyurethane heat preservation systems and phase-transition heat preservation systems, and recycles energy resources; the fireproof performance of the system reaches composite gra
