本発明は無機質繊維マツトを主体とする補強板
状体の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a method for manufacturing a reinforcing plate-like body mainly composed of inorganic fiber mat.
（従来の技術）
未硬化のバインダを含むガラス繊維マツトのよ

しめて得られた板状体（以下「板状体」という）

は軽量である特徴を有する。(Prior art) A plate-shaped body (hereinafter referred to as a "plate-shaped body") obtained by pressurizing and heating fiber mat such as glass fiber mat containing an uncured binder to harden the binder.
has excellent sound absorption and heat insulation properties, and is widely used as interior materials for buildings, vehicles, etc., especially glass fiber "plate-shaped bodies".

いるが（実公昭53−14493号公報参照）、次のよう
な問題点を有する。 However, "plate-shaped bodies" generally have the disadvantage of low mechanical strength, especially bending strength, and if a load is concentrated on one part during handling, they are likely to break or peel off in that part, and this tendency is The smaller the thickness and density of the "plate-shaped body", or the larger its dimensions, the more significant the problem becomes. In order to increase the mechanical strength of the "plate-like body", a method of reinforcing the "plate-like body" by bonding reinforcing members such as FRP or metal plates has been proposed. (see Publication No. 1), and has the following problems.
(1) 「板状体」と補強部材が剥離し易い。(1) The “plate” and the reinforcing member are likely to separate.
(2) 「板状体」の単位面積当りの重量が大とな

り易い。(3) If the "plate-shaped object" is a flat plate-shaped object, the reinforcing material and the fiber mat containing the partially cured binder are layered together, and the binder is cured by applying pressure and heat to form the "plate-shaped object." At the same time, it is also possible to form a "plate-like body" (hereinafter referred to as a "reinforced plate-like body") which is integrally combined with a reinforcing member and reinforced. (Hereinafter, this method will be referred to as the one-piece molding method.) However, if the "plate-like body" has a curved shape, it is difficult to manufacture a reinforced plate-like body by the one-piece molding method. It is necessary to mold the reinforcing members separately and attach them together, which not only complicates the manufacturing process, but also makes it difficult to perfectly match the shapes of the two, and there is a gap between the plate and the reinforcing member. This tends to cause peeling or a decrease in strength.

The phenolic resin is cured by overlapping the objects and heating under pressure.
It has been found that suitable results can be obtained by integrally bonding the mat and the cloth-like material. (Hereinafter, this method will be referred to as the original invention) When the original invention is used, it is possible to obtain a reinforced plate-like body that is lightweight, has excellent heat insulation and sound absorption properties, and has sufficient strength. , it softens under pressure and heat and tends to adhere to the mold used, making it necessary to clean the mold each time or apply a mold release agent to the mold.

わせ一対の型で挾圧し、加熱する。 The above-mentioned uncured fiber mat containing moisture and an A-stage phenolic resin binder (hereinafter referred to as the "main mat") and a cloth-like material containing a B-stage phenolic resin impregnated with a phenolic resin and dried (hereinafter referred to as a dried cloth-like material) ) and a film-like material are stacked together, pressed between a pair of molds, and heated.

により一体的に結合され、剥離も生じないことが
見出された。 The B-stage phenolic resin contained in the cloth-like material dried by heating is once softened and then hardened. For this reason, the cloth-like material can undergo sufficient plastic deformation before hardening, and therefore conforms well to the mold.
Deep drawing is also possible. Simultaneously with the curing due to the crosslinking reaction of the B-stage phenolic resin contained in the dried fabric, the curing due to the crosslinking reaction of the A-stage phenolic resin contained in the mat also proceeds. The resin contained in the dried fabric is B stage (resol), the resin contained in the mat is A stage (resol), and the mat contains a considerable amount of water. Although the weight per unit area is larger and the thickness is larger, both can be cured simultaneously in a short time, the two are firmly bonded together, and the film-like material can also be dried into a cloth-like material. It has been found that the contained phenolic resin binds the material integrally and does not cause peeling.
未硬化の熱硬化性樹脂を含む二つ物体を挾圧し
つつ加熱し、樹脂を硬化させて二つの物体を一体
的に結合する場合、二つの物体に含まれる熱硬化
性樹脂は近似したもの、望ましくは同一のステー
ジのものを使用するのが常識である。 When two objects containing uncured thermosetting resin are squeezed and heated to cure the resin and join the two objects together, the thermosetting resins contained in the two objects are similar, It is common sense to preferably use those of the same stage.
このような常識に反し、本発明なおいて異なる
ステージの樹脂を使用することにより上述のよう
な効果が得られる理由は以下の通りである。 Contrary to such common sense, the reason why the above effects can be obtained by using resins of different stages in the present invention is as follows.
未硬化のマツトはＡステージのフエノール樹脂
及び水分を含んでいる。加熱によりＡステージの
フエノール樹脂の縮合によつても水分が生ずるた
め、未硬化のマツトを加熱すると多量の水蒸気が
発生し、この水蒸気によりＢステージのフエノー
ル樹脂を含む布状物が充分軟化して変形し易くな
り、型馴染みが良好となる。 Uncured mat contains A-stage phenolic resin and water. Moisture is also generated by the condensation of the A-stage phenolic resin during heating, so when uncured mat is heated, a large amount of water vapor is generated, and this water vapor sufficiently softens the cloth-like material containing the B-stage phenolic resin. It becomes easier to deform and has better conformability to the mold.
そして、未硬化のＡステージのフエノール樹脂
を含むマツトを構成する繊維は、自由に動きうる
のに対し、Ｂステージのフエノール樹脂で結合さ

され、拘束されて自由に動き得ない。このため前
者は後者に比し変形し易く型馴染みが良好で深絞
りも可能となる。 The fibers that make up the mat that contains uncured A-stage phenolic resin can move freely, whereas the fibers that make up the mat that is bonded with B-stage phenolic resin are bonded by this resin and restrained. I can't move freely because of it. Therefore, the former is easier to deform than the latter, has better conformability to the mold, and can be deep drawn.

者はよく密着する。 Since the A-stage phenolic resin is more fluid than the B-stage phenolic resin, the phenolic resin contained in the uncured mat sufficiently penetrates into the minute recesses on the surface of the fabric, and the two adhere well. do.
又、布状物に含まれているＢステージのフエノ
ール樹脂の硬化速度は、上記水蒸気の作用により
遅くなり、両者がほぼ同時に完了し、両者が強固
に結合する。 Further, the curing speed of the B-stage phenolic resin contained in the cloth-like material is slowed down by the action of the water vapor, and both are completed almost simultaneously, so that the two are firmly bonded.
Ａステージのフエノール樹脂を含む布状物を使
用した場合、布状物はベトつき作業性が悪く、又
型に樹脂が附着は易い。 When a cloth-like material containing an A-stage phenolic resin is used, the cloth-like material becomes sticky and has poor workability, and the resin easily adheres to the mold.

馴染みが低下し、マツトと布状物との密着が不充
分となり、両者が剥離したり、或は両者の間に隙
間が生じ易い。 In addition, if the mat is heated in advance and the stage phenolic resin contained in the mat is changed to the B-stage phenol resin, moisture is also lost by heating, the mold conformability decreases, and the adhesion between the mat and the cloth-like material is insufficient. As a result, the two tend to separate or a gap is likely to occur between the two.
加熱温度は190〜250℃、好ましくは200〜220℃
とするのが適当であり、加熱所要時間は40〜
120sec程度である。 Heating temperature is 190-250℃, preferably 200-220℃
It is appropriate that the heating time is 40~
It is about 120 seconds.

る。 The density of the resulting "plate" is determined by the weight per unit area of the mat and the distance between the upper and lower molds. The density is determined depending on the use of the "plate-shaped body", but it is usually appropriate to set it to 100 to 400 kg/m 3 .

As a result of the simultaneous curing of the B-stage phenolic resin contained in the cloth-like material and the A-stage phenolic resin contained in the mat, the two are firmly integrated and a sufficient reinforcing effect can be obtained without peeling. Since the dried cloth-like material does not come into direct contact with the mold, the phenol resin contained in the dried cloth-like material does not adhere to the mold, and the film-like material is also firmly integrated with the phenol resin and does not cause peeling.
