させる恐れがある。Among the phenolic resins, among the phenolic resins, the resole type phenolic resin becomes sodium phenoxide in the presence of sodium, becomes water-soluble and is stabilized, and after curing, suppresses the release of formaldehyde due to decomposition of the resin. It is also known that the amount of formaldehyde released further decreases. However, resol-type phenolic resins commonly used in the manufacture of wood fiberboard are highly alkaline, and wood fiberboard using resol-type phenolic resin as a binder can be used as a base material for decorative boards or structural materials. When it is used as a part of, the veneer or decorative paper used as a surface decorative material is discolored to black, and there is a drawback that the surface decorative material is easily contaminated, such as the formation of a colored extract when wet with water. It has the disadvantage that the range is limited. Phenolic resins are generally alkaline, and are not limited to resole phenolic resins.
A wood fiber board using a phenolic resin as a binder may cause contamination of the surface decorative material, though varying in degree.

In this case, if an alkaline putty is used, the surface decorative material is similarly reduced. The material may be contaminated. The present invention has been made in view of these circumstances, even in the case where the wooden base material exhibits alkalinity, contamination such as discoloration of the veneer or decorative paper adhered and laminated on the surface thereof, that is, It is another object of the present invention to provide a decorative board capable of suppressing the occurrence of alkali contamination on a surface decorative material, and a method for manufacturing the same.

は配合量を低減できる利点がある。In the present invention, the resol-type phenolic resin used as one of the binders is a resin in which one or more hydroxyl groups are bonded to a benzene ring or a derivative thereof. More than one species are reacted with aldehydes (formaldehyde) under an alkaline catalyst. Such a phenolic resin is a preferable material when used for the production of a wood fiberboard because it releases a small amount of formaldehyde after curing and has weather resistance. Resol type phenolic resins usually have a pH of 11
About 12 but sodium hydroxide (NaO
Using a hydroxide of an alkali metal such as H) as a catalyst, the reaction was carried out at a molar ratio (AOH / P) of alkali metal hydroxide (AOH) and phenols (P) of 0.1 to 0.3. Since the pH of the resole type phenolic resin is about 10, alkali contamination can be reduced to some extent from the beginning, and there is an advantage that the amount of the acidic substance filled in the adhesive or the amount thereof can be reduced.

It is experimentally selected according to the alkalinity of the wooden base material so that it can be preferably 5 to 6. For example, when the wood substrate is a wood fiber board using a phenol resin as a binder, it is experimentally selected according to the alkalinity and amount of the phenol resin used. By doing so, it is possible to avoid the occurrence of blackening or bluish blacking due to alkali contamination of the surface decorative material. If it is desired to lighten the surface decorative material, the pH may be set to less than 4.0. However, when the pH exceeds 7.0, alkali contamination occurs on the surface decorative material, which is not preferable.
