本発明はエポキシ樹脂積層板の製造に使用される表面処
理されたガラスクロスの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing surface-treated glass cloth used in manufacturing epoxy resin laminates.
従来、エポキシ樹脂積層板に使用されるガラスクロスは
ガラスｗ４紐表面にエポキシ鼻ラン等のカップリング剤
が塗イロされたものでおる。このカップリング剤は無機
物であるカラスと有殿物であるエポキシ樹脂の密着を良
くするためのものて必る。Conventionally, the glass cloth used for epoxy resin laminates has been coated with a coupling agent such as epoxy nose run on the surface of the glass w4 string. This coupling agent is necessary to improve the adhesion between the inorganic glass and the precipitated epoxy resin.
しかし、カップリング剤処理したカラスクロスを使用し
ても、その後の工程てエポキシ樹脂を３餞乾燥した後に
も気泡が残留し、プレス成形後の積層板に気泡か残留す
るという問題か牛ザる。気泡の残留は積層板を加熱した
時気泡の膨張により微小クランク等が発生し、耐熱性、
耐湿性等の劣化の原因となる。However, even if glass cloth treated with a coupling agent is used, air bubbles remain even after the epoxy resin is dried for three times in the subsequent process, and there is a problem that air bubbles remain in the laminate after press molding. . The residual air bubbles are caused by the expansion of the air bubbles when the laminate is heated, resulting in minute cranks, etc., resulting in poor heat resistance,
This may cause deterioration of moisture resistance, etc.

本発明の目的とするところはガラスクロスに工ポキシ樹
脂を含侵ざぜたプリプレグ中の気泡をなくし、プレス成
形後の積層板に気泡の残留をなくすることでおる。(Object of the Invention) The object of the present invention is to eliminate air bubbles in a prepreg obtained by impregnating glass cloth with an engineered poxy resin, and to eliminate air bubbles remaining in a laminate after press molding.
（発明の構成）
本発明は、エポキシ樹脂積層板用ガラスクロスとするも
のてあり、エポキシ樹脂積層板中に気泡の残留を無くす
ことかできるものである。(Structure of the Invention) The present invention provides a glass cloth for use in epoxy resin laminates, and is capable of eliminating residual air bubbles in epoxy resin laminates.
本発明において、表面処理剤はエポキシシラン等のシラ
ンカップリング剤が好ましく使用される。In the present invention, a silane coupling agent such as epoxy silane is preferably used as the surface treatment agent.
エポキシ樹脂による処理は表面処理剤による処理と同時
に行うか、又は表面！ｌａ哩剤による処理の後行うのか
良い。Treatment with epoxy resin should be done at the same time as treatment with surface treatment agent, or the surface! It's best to do it after treatment with a laminar agent.

DI(F), water, etc., but it is preferable to use a solvent with a somewhat high boiling point (for example, 100°C or higher) as at least a part of the solvent in order to improve the impregnation of the epoxy resin into the crow cloth. For the same reason, the concentration of the epoxy resin varnish is preferably 2 to 30% by weight, particularly 2 to 10% by weight. This concentration is considerably lower than the 35-60% by weight concentration of epoxy resin with which such treated glass cloth is subsequently impregnated. The epoxy resin m attached to the glass cloth treated with this low concentration epoxy resin is 2 to 20% by weight, preferably 5 to 15% by weight.
It is.
本発明のガラスクロスの′ｙＡ造方法によれば、その後
の工程でエポキシ樹脂を含侵、乾燥したときプリプレグ
中に気泡が残留せず、プレス成形時に積層板中に気泡が
残留することがない。According to the glass cloth manufacturing method of the present invention, no air bubbles remain in the prepreg when impregnated with epoxy resin in the subsequent process and dried, and no air bubbles remain in the laminate during press molding. .
従って、耐熱成形、耐湿性のすぐれたエポキシ樹脂積層
板を得ることができる。Therefore, an epoxy resin laminate with excellent heat-resistant molding and moisture resistance can be obtained.
