Are preferred. Because the basis weight of the glass fiber nonwoven fabric of insufficient strength is less than 30 g / m 2, it may have difficulty in handling at the time of coating the formulation onto a glass fiber non-woven fabric, or molded or the like, 150 g / m 2 If the ratio exceeds the above, the adhesion between the layers may be insufficient at the time of molding.

い。[0006] Since the blend of phenolic resin and aluminum hydroxide is composed of 3 to 10% by weight of phenolic resin and 97 to 90% by weight of aluminum hydroxide, the decorative board obtained has excellent flame retardancy. However, if the phenolic resin content is 8% by weight or less, it conforms to the Ministry of Construction Notification No. 1828, “Designating Noncombustible Materials”. If the phenolic resin is less than 3% by weight, the phenolic resin cannot sufficiently function as a binder, so that there is a problem in handling the core material layer sheet material and in the interlayer strength after molding, which is not preferable.

すい等の欠点が生じてくる。This composition is used as it is or after being diluted with a diluent such as water or alcohol. In this composition, when the ratio of a diluent such as water and alcohol (including those originally contained in the resin) to the solid content is defined as the dilution ratio, the dilution ratio depends on the ratio of the resin in the formulation. , Usually about 0.05 to 0.5, preferably about 0.1 to 0.3. If it is smaller than this range, the viscosity of the composition is high, making it difficult to perform coating. If it is larger, the viscosity is low, and the coated composition is less likely to be held on the glass fiber nonwoven fabric. Next, if necessary, the diluted composition is applied to a glass fiber nonwoven fabric. Assuming that the ratio of the compound (solid content) to the glass fiber nonwoven fabric at the time of coating is the impregnation rate, the impregnation rate depends on the basis weight of the glass fiber nonwoven fabric,
Usually about 5 to 100 times by weight, preferably 10 to 60 times
About twice. If it is less than 5 times, it is difficult to maintain the required thickness and the surface finish may not be sufficient. Further, the flame resistance decreases and the cost increases. If it exceeds 100 times,
It has good flame resistance, but has drawbacks such as easy collapse during handling of the core layer sheet material.

When a material having a small particle size is used alone, the uniformity of the core material layer sheet material or the decorative plate can be ensured, but the workability at the time of mixing the mixture is difficult. When a material having a large particle size is used alone, it is difficult to handle the obtained core material layer sheet material, and at the same time, a decrease in nonflammability due to a decrease in the particle surface area is observed. The close-packing of aluminum hydroxide with different particle diameters improves the wettability of the compound when preparing the sheet material for the core layer, as well as the workability when mixing the compound, the handling of the sheet, and the incombustibility. Etc. are also favorable, which is preferable. As for this particle size, a large one has an average particle diameter of 100 to 200 μm and a small one has an average particle diameter of 1 to
20 μm is preferred. In order to increase the packing density, it is preferable that the distribution of both particle diameters is within a range of about ± 50% around the average particle diameter, and the ratio of both average particle diameters is 5 to 5.
About 200 is preferable.

The glass fiber woven fabric impregnated with the thermosetting resin and used to obtain the sheet material for the reinforcing layer has a basis weight of 50 to 350 g / m 2 ,
Furthermore, 100-300 g / m < 2 > is preferable. The thermosetting resin is not particularly limited, such as a melamine resin and a phenol resin, but is preferably a melamine resin in terms of flame resistance. As for the ratio of the thermosetting resin to the glass fiber woven fabric, the higher the ratio, the better the adhesion to the core material layer sheet material, but the lower the flame resistance. Is good, but the adhesion to the core material layer sheet material is reduced,
The reinforcing effect is reduced. Therefore, in order to obtain a reliable reinforcing effect and good flame resistance, the impregnation rate of the thermosetting resin is
Usually 20 to 150 parts per 100 parts by weight of glass fiber woven fabric
Parts by weight, preferably 25 to 100 parts by weight. By inserting such a sheet material for a reinforcing layer between two or more sheet materials for a core layer to obtain a decorative board, dimensional change, warpage, deformation, etc. are small, and shape retention after combustion is good. The effect of improving the flame resistance is great.

が小さい。According to the present invention, there is provided a decorative board for two or more core material layers in which a mixture of a phenol resin and aluminum hydroxide is applied to a glass fiber nonwoven fabric at a phenol resin content of 10% by weight or less. A sheet material for a reinforcing layer in which a thermosetting resin is impregnated into a glass fiber woven fabric is inserted between the sheet materials, and a decorative layer or an equivalent thereof is laminated and integrated on the front surface or the front and back surfaces of the core material layer sheet material. As a result, the obtained decorative board has a small dimensional change, warpage, deformation, and the like, the amount of heat generated during combustion and the amount of smoke generated are suppressed to a small amount, and the shape destruction after combustion is small.
