ある。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a panel with a sandwich structure in which thin metal sheets are used as front and back materials and a special constituent material is used as a core material. The present invention relates to a sandwich-structured fire-resistant panel that can effectively utilize its performance to pass fire-resistant construction.

密度に充填したパネルの構造が一般的であった。Although the core material in this type of panel is lightweight, it lacks fire retardant properties, so inorganic aggregates and inorganic powders such as perlite grains, borax, vermiculite, ammonium polyphosphate, and calcium carbonate are mixed into the core material. The most common structure was a panel in which the surface layer of the core material was densely packed.

。However, in this type of structure, the core material changes from liquid → creamy → foam → solidified foam in about 1 to 5 minutes, and the inorganic aggregate, inorganic powder, and inorganic fiber are the raw materials for the core material. Because it absorbs or adsorbs oil, it disturbs the reaction system of the raw materials, and the mixing of each component of the raw materials becomes uneven, which has a large negative effect on the foaming ratio and foam structure, resulting in increased costs and inferior mechanical strength. There was a disadvantage. Furthermore, when a resol type phenolic resin raw material is used, the condensed water during the reaction has a large adverse effect on adhesive properties, especially when the front and back materials are impermeable. Of course, in order to pass fire protection and fireproof construction, it is necessary to add a large amount of the above-mentioned inorganic materials, which reduces the weight reduction by half and makes it difficult to form a uniform fire protection layer. The above-mentioned problems also occurred in the reaction system and the foamed structure.

性にもすぐれた耐火パネルを提案するものである。In order to eliminate these drawbacks, the present invention eliminates the negative effects of condensed water on adhesion during the formation of phenol foam by absorbing water through the water-holding power of the inorganic aggregate of the core material, or by using a water-absorbing resin as a binder. This project proposes a fire-resistant panel that can reliably pass fire-resistant construction without compromising fire protection and fire resistance, and is also lightweight, has excellent heat insulation properties, and is highly productive.
