As a result, a gap is formed in the connecting portion, from which heat and flame leak to the opposite side, and J
There was a drawback that the test for the refractory structure of IS-A-1304 for 1 hour could not be passed. Furthermore, this type of composite panel, particularly a composite panel manufactured by discharging a core material in a liquid state, a granular state, or the like, has the following disadvantages. That is, when the resol type phenol foam is used as the core material,
As a result of solar heat, free water, condensed water, and unreacted water in the core material evaporate over time, so that the core material contracts as a whole. The surface material made of metal expands due to solar heat, whereas the core material made of phenol foam lacks elasticity and is brittle compared to other plastic foams, so the core material cannot follow the deformation of the surface material and cohesive failure occurs, causing surface material Is pekoe and spoils the appearance. Since the core material is water-absorbing, it is necessary to sufficiently enhance waterproofness when constructing the composite panel. The strength of adhesion between the surface material, the back surface material and the core material is weak, and a slight impact causes the surface material, the back surface material and the core material to be peeled off, particularly at the ends. In particular, surplus gas is generated during the high temperature of midsummer (when the surface material is heated). There were disadvantages.

る。As described above, according to the fireproof panel of the present invention, unnecessary gas generated during the reaction is greatly reduced by using polyisocyanate as a core material.
Moreover, since it is released to the outside through the cell film, the adhesive strength between the surface material, the back surface material and the core material is not lowered for a long period of time. The weakness of polyisocyanurate foam in fire resistance can be strengthened by adding an inorganic powder, and the performance that can pass the fire resistance test can be improved. In a fire-resistant panel using phenol foam as a core material, the acidity (about PH2) in the phenol foam can be kept low at PH5 by the inorganic powder, and the strength of the coating film can be strengthened to about 4 times that of the conventional one. When the ventilation hole forming member is transferred between the surface material and the plastic foam, the gas pressure is further reduced, and various problems can be greatly improved. The fire resistance and fire resistance can be more surely improved by adding the resol type phenol resin powder. In the production of various foams, since the inorganic powder is fine particles, they can be mixed very easily and a desired foam can be formed. There are features and effects such as.
