〈産業上の利用分野〉
この発明は建築用板に関し、詳しくは補強繊維で補強さ
れた発泡フェノール樹脂より成る建築用板材に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a construction board, and more particularly to a construction board made of a foamed phenolic resin reinforced with reinforcing fibers.
〈従来の技術〉
従来、建築用板材の成形素材としてフェノール樹脂が使
用されることがある。<Prior Art> Conventionally, phenolic resin has been used as a molding material for architectural boards.
このフェノール樹脂を素材とする繊維補強成形体は高強
度であり、かつ耐燃性であるので建築用板としては好適
であると言える。This fiber-reinforced molded product made of phenolic resin has high strength and is flame resistant, so it can be said to be suitable as a construction board.
しかしながら、このフェノール樹脂を素材とする繊維補
強建築用板を得る場合、充分に高強度のものとなし得な
いといった問題があった。However, when obtaining a fiber-reinforced building board made of this phenolic resin, there is a problem that it cannot be made with sufficiently high strength.
〈従来の問題点〉
即ち、レゾール系フェノール樹脂材料が高粘度であるた
め、補強繊維の均一分散混入が非常に困難となり、例え
ば、上記高粘度のレゾール系フェノール樹脂材料中に補
強繊維を混入して混練しても繊維が塊状に固まり均一分
散しない。<Conventional problems> In other words, since the resol-based phenolic resin material has a high viscosity, it is very difficult to uniformly disperse and mix reinforcing fibers into the resol-based phenolic resin material. Even if the fibers are kneaded, the fibers will clump together and will not be uniformly dispersed.
従って、繊維補強フェノール樹脂建築用板を得る場合、
補強繊維をマット状となし、これにレゾール系フェノー
ル樹脂を含浸させ、このマットを積層するか、あるいは
レゾール系フェノール樹脂を層間に塗布して積層し、こ
れを圧縮一体化するといった手段が採用されるが、既述
のようにレゾール系フェノール樹脂が高粘度であるため
、積層された層間に充分な融合密着が行なわれず、層間
剥離を生じるといった問題があった。Therefore, when obtaining fiber-reinforced phenolic resin building boards,
The reinforcing fibers are made into a mat, impregnated with resol-based phenolic resin, and the mats are laminated, or resol-based phenolic resin is applied between the layers and laminated, and then compressed and integrated. However, as mentioned above, since the resol type phenolic resin has a high viscosity, there is a problem that sufficient fusion adhesion is not achieved between the laminated layers, resulting in delamination.
〈発明が解決する問題点〉
この発明は上記問題点に鑑み、レゾール系フェノール樹
脂組成物と補強繊維とが充分に一体化され、補強繊維の
補強効果も充分に発揮される建築用板を得ることを目的
としてなされたものである。<Problems to be Solved by the Invention> In view of the above-mentioned problems, the present invention provides a building board in which a resol-based phenolic resin composition and reinforcing fibers are sufficiently integrated and the reinforcing effect of the reinforcing fibers is fully exhibited. It was done for that purpose.
〈問題点を解決するに至った技術〉
この発明の建築用板材は、発泡フェノール樹脂より成る
成形板体中に、補強繊維が平面に拡散されかつ、厚さ方
向に均一分散されて成ることを特徴上するものである。<Technology that led to the solution of the problem> The architectural board material of the present invention consists of a molded board made of foamed phenolic resin, in which reinforcing fibers are diffused in a plane and uniformly dispersed in the thickness direction. It is characterized by its characteristics.
〈実施例〉 次に、この発明の詳細な説明する。<Example> Next, the present invention will be explained in detail.

Any fibers such as polyester that are generally used as reinforcing fibers can be used.
次に、この発明の建築用板の製造方法について説明する
。Next, a method for manufacturing a construction board according to the present invention will be explained.

どの中に複数枚積層し、しかる後発泡剤混入レゾール系
フェノール樹脂を加熱等により発泡させる。As shown in FIG. 2, a non-woven mat 2A is formed using the reinforcing fibers as described above, and this mat is impregnated with a resol-based phenolic resin mixed with a foaming agent. As shown in the figure, a plurality of sheets are laminated in a mold 3 or the like, and then the resol-based phenolic resin mixed with a foaming agent is foamed by heating or the like.
このとき、レゾール系フェノール樹脂は発泡時の体積膨
張ｔこよって不織布状のマツ）２Ａ。At this time, the resol-based phenolic resin has a volumetric expansion t during foaming, which results in a nonwoven fabric-like pine) 2A.
２Ａの構成繊維を三次元的に移動させ、発泡フェノール
樹脂層内に平面方向に配向させて補強繊維を拡散させ厚
さ方向に均一分散状とするのである。The constituent fibers of 2A are moved three-dimensionally and oriented in the plane direction within the foamed phenolic resin layer, thereby diffusing the reinforcing fibers and making them uniformly dispersed in the thickness direction.
しかも、層界面においては、発泡フェノール樹脂は、厚
さ方向へも膨張するからこの膨張圧力により各層間は強
力に融合密着し、明瞭な層界面も生じない。Moreover, since the foamed phenolic resin expands in the thickness direction at the layer interfaces, the expansion pressure causes the layers to be strongly fused and adhered, and no clear layer interfaces occur.
かくして、補強繊維が平面方向に拡散され厚さ方向にも
均一分散状とされた発泡フェノール樹脂より成る建築用
板が得られるのである。In this way, a construction board made of a foamed phenolic resin in which the reinforcing fibers are diffused in the planar direction and uniformly dispersed in the thickness direction can be obtained.
なお、上記発泡フェノール樹脂材料の充填剤として、例
えば水酸化アルミ（Ａ１２（ｏＨ）ａ）を添加すれば、
耐火性をさらに向上出来都合が良い。In addition, if aluminum hydroxide (A12(oH)a) is added as a filler to the foamed phenolic resin material, for example,
It is convenient because the fire resistance can be further improved.
以下、この発明の具体的な実施例を説明する。Hereinafter, specific examples of the present invention will be described.
