As a material for this purpose, a lightweight thermosetting resin molded body consisting of a core layer mainly made of pumice and a surface layer reinforced with inorganic fibers is known (Japanese Patent Publication No. 59-1
Publication No. 3473). However, this method has the drawback that, depending on the inorganic powder used, the difference in specific gravity between the pumice and the inorganic powder becomes large, and the two become separated and unevenly stacked, making the molding operation complicated. Additionally, there are restrictions on the inorganic powders that can be used.

As a raw material for the surface layer, a thermosetting resin is blended with an inorganic powder, and both are mixed, stirred, or kneaded. In the case of liquid resin, adjust the solvent by evaporation until the required fluidity is achieved.
A dry mixture 1 of inorganic powder and thermosetting resin is prepared. Next, reinforcing fibers 2 are blended into this mixture 1, and a certain amount of the reinforcing fibers 2 are sprinkled onto a suitable release sheet to form a mat for the surface layer. At this time, especially when strand-shaped fibers are used, mix 1 is sprinkled on a release sheet without mixing mixture 1 and reinforcing fiber 2 in advance, and then strand-shaped fibers are used. By scattering the fibers and then again scattering the mixture 1 thereon, a mat in which the reinforcing fibers 2 are dispersed in the mixture 1 of inorganic powder and thermosetting resin can be formed. Depending on this method, the fibers are not mechanically damaged and at the same time the degree of freedom in blending amount can be increased.

、耐火性等性能付与の自由度を大きくできた。[Operation] Thus, the composite panel of the present invention uses an inorganic lightweight aggregate whose surface is coated with a mixture of inorganic powder or inorganic short fibers and a thermosetting resin. The coating layer is compressed and comes into point-like contact, and then the thermosetting resin reacts and hardens due to heat transfer, so that the inorganic lightweight aggregates are bonded and integrated with each other. At this time, even if an attempt is made to coat the surface of the lightweight aggregate by adding only a resin, the resin will penetrate into the porous surface and will not form an effective adhesive layer. The covering layer substantially uniformly covers the inorganic lightweight aggregates and forms a shell-like reinforcing layer, which greatly improves the strength of these lightweight aggregates. In addition, since the lightweight aggregate is bonded in dots, many gaps between particles remain, which keeps the core layer lightweight and improves its heat insulation properties. Furthermore, since the surface layer reinforced with fibers is placed on one or both sides of the core layer and is integrally molded, the bond between the surface layer and the core layer is strong.
A reasonable two-layer or three-layer structure is formed. In this way, by coating the surface of the lightweight aggregate with inorganic powder or short inorganic fibers in advance, it was possible to prevent the layers of the lightweight aggregate and the inorganic powder or short fibers from separating or stacking up unevenly. Therefore, it has become possible to use powder or short fibers with a large difference in specific gravity in combination with lightweight aggregates, increasing the degree of freedom in imparting properties such as strengthening and fire resistance to lightweight aggregates.

軽量骨材の表面をあらかじめ無機質粉体ないしは無機質
短繊維と熱硬化性樹脂で被覆したものをコア層の骨材と
して使用し、強化用繊維と無機質粉体及び熱硬化性樹脂
を主体とする表面層と一体化することにより、軽量性、
加工性、厚み精度に優れた３層構造の複合材料であり、
特に壁材、床材等の軽量複合パネルとして利用度の高い
製品にある。As described above, in the present invention, inorganic lightweight aggregate whose surface is coated with inorganic powder or inorganic short fibers and a thermosetting resin is used as the aggregate for the core layer to strengthen it. By integrating the fiber and the surface layer mainly composed of inorganic powder and thermosetting resin, it is lightweight and
It is a three-layer composite material with excellent workability and thickness accuracy.
This is especially true for products that are frequently used as lightweight composite panels for wall materials, flooring materials, etc.
