形している。However, in the production of conventional laminates, a prepreg is obtained by a method of impregnating and drying an epoxy resin without any treatment on a glass nonwoven fabric, or after performing a coupling agent treatment and then impregnating and drying the epoxy resin. , This is laminated.
発明が解決しようとする課題 ところが、ガラス不織布の製造で分散剤として使用した
界面活性剤は、成形した積層板が吸湿するとイオン化し
て、積層板の絶縁抵抗を下げる大きな要因となる。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, the surfactant used as the dispersant in the production of the glass nonwoven fabric is ionized when the molded laminate sheet absorbs moisture, and becomes a major factor of lowering the insulation resistance of the laminate sheet.
本発明はこの知見に基づき、吸湿後の絶縁抵抗の低下が
少ないガラス不織布基材エポキシ樹脂積層板を提供する
ことを目的とする。The present invention is based on this finding, and an object thereof is to provide a glass non-woven fabric-based epoxy resin laminate having less decrease in insulation resistance after moisture absorption.

るものである。Means for Solving the Problems In order to achieve the above object, in the present invention, a glass nonwoven fabric is washed with water and dried, and then impregnated with an epoxy resin and dried to obtain a prepreg. Alternatively, the glass nonwoven fabric is washed with water, dried, treated with a coupling agent, impregnated with an epoxy resin and dried to obtain a prepreg. Then, these prepregs are laminated and molded.

物質、特にイオン性物質が除去される。これにより、積
層板中の吸湿によりイオン化する物質の量が減じられ、
吸湿による絶縁抵抗の低下を抑制することができる。Action By washing the glass non-woven fabric with water, water-soluble substances, especially ionic substances, attached to it are removed. This reduces the amount of substances that ionize due to moisture absorption in the laminate,
It is possible to suppress a decrease in insulation resistance due to moisture absorption.
ガラス不織布を水洗後の乾燥は、水分を除去してガラス
繊維とエポキシ樹脂の接着力を低下させないためである
が、水洗乾燥後にカップリング剤処理を施しておくこと
により、接着力は向上する。The drying of the glass non-woven fabric after washing with water does not remove water to reduce the adhesive strength between the glass fiber and the epoxy resin. However, the adhesive strength is improved by applying a coupling agent treatment after washing with water and drying.
