この発明は繊維強化フェノール樹脂発泡体の製造方法に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a method for producing a fiber-reinforced phenolic resin foam.
高強度、耐燃性を有する壁板として繊維強化発泡フェノ
ール樹脂製板材が広く用いられている。Fiber-reinforced foamed phenolic resin boards are widely used as wallboards with high strength and flame resistance.
ところで、上記板材を製造する場合、酸硬化系フェノー

かる問題点を解消するため、本願出願人は特願昭６０−
１４７３３７号に開示したように成形コンヘヤ上に粘性
の高いフェノール樹脂を供給し、その上に補強繊維シー
トを積層供給し、上から押圧することにより強制的に樹
脂を連続的に含浸していく方法を提案した。By the way, when manufacturing the above-mentioned board materials, the acid-curing phenolic resin has a high viscosity and is difficult to mix with reinforcing fibers.
As disclosed in No. 147337, a method in which a highly viscous phenolic resin is supplied onto a molding conveyor, a reinforcing fiber sheet is laminated and supplied on top of the molding conveyor, and the resin is continuously impregnated by force by pressing from above. proposed.
上記手段によりフェノール樹脂の連続含浸が可能となり
、繊維強化フェノール樹脂板の成形の効率化が図られた
のであるが、硬化剤を既に混合したフェノール樹脂を用
いるため、樹脂供給から補強繊維シート含浸に至るまで
の時間が短く充分均一な含浸状態となし得ないことが有
る問題があった。The above method made it possible to continuously impregnate the phenolic resin sheet and improve the efficiency of molding the fiber-reinforced phenol resin sheet. However, since the phenol resin with the hardening agent already mixed in was used, there was no need for the resin supply to the reinforcing fiber sheet impregnation. There is a problem that it takes a short time to achieve a sufficiently uniform impregnated state.
さらにフェノール樹脂を発泡させる場合は充分な発泡が
終了しないままに硬化が完了してしまうことが有り、均
一な含浸状態の製品、ないしは発泡伏皿となった製品が
得られないことが存る欠点が有った。Furthermore, when foaming phenolic resin, curing may be completed before sufficient foaming is completed, which has the disadvantage that it may not be possible to obtain a product with a uniform impregnated state or a foamed product. There was.
この発明は上記問題点に鑑み、含浸ないしは発泡が均一
かつ完全に行なえ実施も容易な繊維強化フェノール樹脂
発泡体の製造方法を提供することを目的としてなされた
ものである。The present invention has been made in view of the above-mentioned problems, with the object of providing a method for producing a fiber-reinforced phenolic resin foam that can be impregnated or foamed uniformly and completely and is easy to implement.

。That is, the method for producing a fiber-reinforced phenolic resin foam of the present invention is characterized by impregnating a reinforcing fiber sheet only with a curing agent, then impregnating the reinforcing fiber sheet with a phenol resin mixed with a foaming agent, and foaming and curing. It is something to do.
次にこの発明の詳細な説明する。 Next, this invention will be explained in detail.
第１図はこの発明の方法の一実施装置を示す側面図であ

。In the method for producing a fiber-reinforced phenolic resin foam according to the present invention, a reinforcing fiber sheet 1 made of, for example, glass fiber non-woven fabric is passed through a tank 2A filled with a hardening agent 2.
The reinforcing fiber sheet 1 is impregnated with
On this heald conveyor 3, the phenolic resin 4 with no curing agent mixed is supplied onto the reinforcing fiber sheet 1, and the reinforcing fiber sheet 1 is impregnated with the resin 4 using a doctor knife or rollers 5, 5. During this impregnation, fiber sheet 1
It is cured by reacting with the curing agent contained in it.
上記において、フェノール樹脂４には発泡剤を配合した
ものも用いることが出来る。In the above, the phenol resin 4 may also contain a blowing agent.

化剤２を均一に含浸させ得る手段であれば特に限定され
ない。In the above embodiment, dipping is used as a means for impregnating the fiber sheet 1 with the curing agent 2, but the method is not limited to this, and the fiber sheet 1 may be uniformly impregnated with the curing agent 2 by, for example, a spraying method, a brushing method, etc. There are no particular limitations as long as it is a means.
この発明において、フェノール樹脂の硬化剤２は繊維シ
ート１に含浸されているため、フェノール樹脂の硬化は
繊維シート１に含浸されなければ生じない。In this invention, since the phenol resin curing agent 2 is impregnated into the fiber sheet 1, the curing of the phenol resin does not occur unless the fiber sheet 1 is impregnated.
よって、粘調度の高い樹脂原料であっても、充分に繊維
シート１に含浸可能となり、また、発泡反応も充分に行
なわせることが出来る。Therefore, even if the resin raw material has a high viscosity, it can be sufficiently impregnated into the fiber sheet 1, and the foaming reaction can also be carried out satisfactorily.
この発明は以上説明したように繊維シートに樹脂が含浸
されない限り硬化反応が生じないので、充分な含浸が可
能となり、また、その間に発泡も充分行なわせることが
出来るので均一な材質の板材が成形可能となるのである
。As explained above, in this invention, the curing reaction does not occur unless the fiber sheet is impregnated with the resin, so sufficient impregnation is possible, and sufficient foaming can be carried out during this time, so that a plate of uniform material can be molded. It becomes possible.
