Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明はフェノール樹脂の繊維含浸方法に関する。[Detailed description of the invention] [Industrial application field] This invention relates to a method for impregnating fibers with phenolic resin.
従来、フェノール樹脂は、比較的高い難燃性を有し、従
ってこの性質を利用して建材などを製造することが広く
行なわれている。Conventionally, phenolic resins have relatively high flame retardancy, and therefore, this property has been widely used to manufacture building materials and the like.
ところで、フェノール樹脂による成形品はそのままでは
脆い性質を有し、特に発泡体にあってはその性質が顕著
となるため、ガラス繊維等補強繊維により補強すること
が一般に行われる。By the way, molded products made of phenolic resin have brittle properties as they are, and this property is particularly noticeable in foamed products, so it is generally reinforced with reinforcing fibers such as glass fibers.
しかしながら、原料となる液状フェノール樹脂は、一般
にIOP以上の高粘度であるため、ストランド化された
ガラス繊維内に均一に含浸させることは困難で、例え浸
漬時間を長くしても樹脂含浸状態に疎密ができやすく均
一な製品強度とし難いと言った問題があった。However, since the raw material liquid phenol resin generally has a high viscosity higher than IOP, it is difficult to uniformly impregnate stranded glass fibers, and even if the immersion time is long, the resin impregnation state will not be dense. There was a problem that it was difficult to obtain uniform product strength.
〔発明が解決しようとするi!l!題〕この発明は上記
問題点に鑑み、ストランド化された補強繊維であっても
、繊維の東向に十分に樹脂を行き渡らせ、もって強度に
優れた成形品となし得るフェノール樹脂の繊維含浸方法
を提供することを目的としてなされたものである。[The invention tries to solve i! l! [Problem] In view of the above-mentioned problems, the present invention provides a method for impregnating fibers with phenolic resin, which allows the resin to be sufficiently spread in the east direction of the fibers even when reinforcing fibers are made into strands, thereby producing molded products with excellent strength. It was made for the purpose of providing.
即ち、この発明のフェノール樹脂の繊維含浸方法は粉末
状フェノール樹脂を繊維間に介在させてストランド化し
た補強繊維ロービングを前記粉末状フェノール樹脂より
も反応性の高い液状フェノ−ル樹脂液中に浸漬し、該液
状フェノール樹脂でコーティングすることを特徴とする
ものである。That is, the method of impregnating fibers with phenolic resin of the present invention involves immersing reinforcing fiber rovings, which are formed into strands by interposing powdered phenolic resin between the fibers, into a liquid phenolic resin solution that is more reactive than the powdered phenolic resin. It is characterized in that it is coated with the liquid phenol resin.
この発明において、補強繊維に均一な樹脂含浸を行なう
にあたり、わ)未樹脂と液状フェノール樹脂とを併用す
る。In this invention, in uniformly impregnating reinforcing fibers with resin, (c) non-resin and liquid phenol resin are used in combination.
即ち、ストランド化された補強繊維の繊維間には高粘度
の液状フェノール樹脂の浸透が困難なため、この繊維間
に予め前記液状フェノール樹脂より反応性の低い粉末フ
ェノール樹脂を混入しておく。That is, since it is difficult for a high-viscosity liquid phenol resin to penetrate between the fibers of the stranded reinforcing fibers, a powdered phenol resin having a lower reactivity than the liquid phenol resin is mixed in advance between the fibers.
そして、上記のように編成したストランドを粉末フェノ
ール樹脂より反応性の高い液状フェノール樹脂浴させ、
表面をコーティングする。Then, the strands organized as described above are bathed in a liquid phenol resin, which is more reactive than a powdered phenol resin.
Coat the surface.
従って、ストランドの内部には、粉末、表面には液状の
フェノール樹脂が実質的に存在することとなる。Therefore, powder is substantially present inside the strand, and liquid phenol resin is substantially present on the surface.
上記粉末と液状のフェノール樹脂の反応性を相互に異ら
せるのは、フェノール樹脂の加熱反応時、まず、外表面
から樹脂を硬化させ、次いで内部樹脂を硬化させるため
であって、これより内部樹脂の外部への漏出を防ぐため
である。The reason why the reactivity of the powdered and liquid phenolic resins differs from each other is that during the heating reaction of the phenolic resin, the resin is first hardened from the outer surface, then the internal resin is hardened, and then the internal resin is hardened. This is to prevent resin from leaking to the outside.
上記実質的にフェノール樹脂を含浸させたストランドは
、そのまま成形工程へ送られ、金型などにより所定断面
形状の成形品に成形される。The strand substantially impregnated with the phenolic resin is sent as it is to a molding process, and is molded into a molded product with a predetermined cross-sectional shape using a mold or the like.
次に、この発明の詳細な説明する。 Next, the present invention will be explained in detail.
(200)メツシュの粉末フェノール樹脂をガラス繊維
モノフィラメントにふりかけつつ、10本づつ束ねて、
わずかによりを与えてストランド化した。(200) Sprinkle mesh powdered phenolic resin onto glass fiber monofilaments and bundle them into 10 pieces at a time.
It was made into strands with a slight twist.
これを連続的に粘度10Pの液状フェノール樹脂槽へ引
き通し、コーティングを行ない、その後、ストランドを
所定本数束ねてインドルーダ金型へ送入し、加熱して成
形品を成形した。This was continuously passed through a liquid phenol resin tank having a viscosity of 10P to be coated, and then a predetermined number of strands were bundled and fed into an intruder mold and heated to form a molded product.
半径5朋、長さl■の棒状の成形品につき、曲げ強度を
測定したところ、表1の結果となった。The bending strength of a rod-shaped molded product with a radius of 5 mm and a length of 1 cm was measured, and the results shown in Table 1 were obtained.
なお、表1中比較例は高粘度液状フェノール樹脂に引き
通すだけの処理をした繊維を用いて成形したものである
。The comparative examples in Table 1 were molded using fibers that had been treated to be drawn through a high viscosity liquid phenol resin.
この発明は以上説明したように、含浸の困難な樹脂であ
ってもスラリー化した補強繊維の繊維間に粉末状フェノ
ール樹脂を混在せしめたため、これら構成繊維間に充分
に樹脂が行き渡り、しかも内外樹脂の反応性に差をもた
せたため、内部樹脂の外部漏出も有効に防止され、もっ
て強度の均一な、かつ、強度に優れたFRPを成形でき
るなどの効果を有する。As explained above, in this invention, even if the resin is difficult to impregnate, the powdered phenol resin is mixed between the fibers of the slurry-formed reinforcing fibers, so that the resin is sufficiently distributed between the constituent fibers, and the inner and outer resins are Since there is a difference in reactivity, leakage of the internal resin to the outside can be effectively prevented, which has the effect of molding FRP with uniform strength and excellent strength.
