本発明は無機質繊維マツトを主体とする補強板
状体の製造法に関するものである。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a method for manufacturing a reinforcing plate-like body mainly composed of inorganic fiber mat.

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

となり易い。(3) If the "plate-like object" is a flat object, the reinforcing member and the fiber mat containing an uncured binder are layered together, and the binder is cured by applying pressure and heat to form the "plate-like 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 integral molding method.) However, if the "plate-shaped body" has a curved shape,
It is difficult to manufacture a reinforcing plate-like body using the integral molding method, and it is necessary to mold the plate-like body and the reinforcing member separately and attach them together, which not only complicates the manufacturing process but also requires the shape of both to be made separately. It is difficult to match them completely, and a gap is created between the "plate-shaped body" and the reinforcing member, which tends to cause peeling or a decrease in strength.

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。 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. It was found that although the weight per unit area is greater and the thickness is greater, both can be cured at the same time in a short time, and the two are firmly and integrally bonded without peeling. . When two objects containing uncured thermosetting resin are heated while being squeezed together to harden 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、本発明において、異る
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

のフエノール樹脂で結合されたマツトを構成する
繊維同志はこの樹脂で結合され、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。 Uncured pine 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 conforms to the mold better. And uncured A
The fibers constituting the mat containing the phenolic resin in the stage can move freely, whereas the fibers constituting the mat bonded with the phenolic resin in the B stage are bound by this resin and are restrained and cannot move freely. do not have. Therefore, the former is easier to deform than the latter, has better conformability to the mold, and can be deep drawn.
そして、Ａステージのフエノール樹脂はＢステ
ージのフエノール樹脂に比べて流動し易いため、
未硬化マツトに含まれているフエノール樹脂は布
状物表面の微少な凹部にも充分入り込み、両者は
よく密着する。 Since A-stage phenolic resin is more fluid than B-stage phenolic resin,
The phenolic resin contained in the uncured mat sufficiently penetrates into minute recesses on the surface of the cloth-like material, and the two adhere well.
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、両者の硬化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 the curing of both is 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
型に樹脂が附着し易い。 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 tends to adhere to the mold.
又マツトを予め加熱し、マツトに含まれるＡス

した場合、加熱により水分も失われて型馴染みが
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 A-stage phenolic resin contained in the mat is heated to bring it to the B stage, the heating will also cause water loss, resulting in poor mold conformability and insufficient adhesion between the mat and the cloth-like material. 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.

下型の間隔によつて、得られる「板状体」の密度

れるが通常100〜250Kg／m3とするのが適当であ
る。 The density of the resulting "plate-like material" 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-like material", but it is usually appropriate to have a density of 100 to 250 kg/ m3 .

ることなく充分な補強効果が得られる。(Function) The B-stage phenolic resin contained in the dried fabric is softened by heating, and the dried fabric can be plastically deformed under the action of moisture generated from the mat, and it conforms well to the mold, making it easier to dry. As a result of the simultaneous curing of the B-stage phenolic resin contained in the fabric and the A-stage phenolic resin contained in the mat, both are firmly integrated and a sufficient reinforcing effect can be obtained without peeling.
