REFRACTORY HEAT INSULATION COMPOSITE PANEL

摘要

PURPOSE: To provide a refractory heat insulation composite panel for controlling the reduction of bonding force between a resol type phenol foam and metal bases generated by the deviation of expansion and contraction by heat and an unreacted material, a remaining material and a reaction product (water) at the time of forming the foam. CONSTITUTION: In a refractory het insulation composite panel in which a resol type pheno foam 1 is interposed integrally between metal bases 2 and 3, a resin film 6 to bond easily with the resol type phenol foam 1 is interposed and formed integrally on the surface of the metal bases 2 and 3 being in contact with the resol type phenol foam 1.
