（産業上の利用分野）
本発明は、耐熱性、耐水性および耐電食性に優れた積層
板に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a laminate having excellent heat resistance, water resistance and electrolytic corrosion resistance.
（従来技術とその問題点）
近年、電子機器工業の著しい発展に伴い、回路の高密度
化が進み、ざらに耐熱性にも優れた積層板が求められて
いる。(Prior art and its problems) In recent years, with the remarkable development of the electronic equipment industry, the density of circuits has increased, and there is a demand for laminates with excellent heat resistance.
一方、上記の如き回路の高密度化により、隣接する回路
間において、電位差により銅が溶は出し、これにより両
電極間にブリッジを形成し、短絡を生じさせるいわゆる
デンドライト（電食）も問題となってきている。On the other hand, due to the high density of circuits as described above, copper is dissolved due to the potential difference between adjacent circuits, and this causes a bridge between the two electrodes, causing a short circuit, which is called dendrite (electrolytic corrosion). It has become to.
そこで、電気的特性、化学的特性に優れた、紙エポキシ
基材よりなる積層板が、上記要求に対応すべく開発、研
究されている。Therefore, a laminate made of a paper epoxy base material with excellent electrical and chemical properties has been developed and researched to meet the above requirements.

ール樹脂を下塗り樹脂に用いた積層板は、耐熱性、耐水
性、絶縁性特性に劣るという問題点がある。By the way, the paper epoxy base material is conventionally undercoated with a water-based varnish such as phenol resin because epoxy resin has poor impregnating properties into paper. However, the above-mentioned phenol resin is inferior to epoxy resin in terms of heat resistance and water resistance, and its insulation properties are also inferior to epoxy resin. Therefore, a laminate using the above-mentioned phenol resin as an undercoat resin has a problem in that it is inferior in heat resistance, water resistance, and insulation properties.
（発明の目的） 本発明は、上記問題点に鑑み、耐熱性、耐水性。(Purpose of the invention) In view of the above problems, the present invention provides heat resistance and water resistance.
絶縁特性等に優れた積層板の製造方法を提供することを
目的とする。The purpose of the present invention is to provide a method for manufacturing a laminate with excellent insulation properties.

方法に関する。(Means for Solving the Problems) The present invention impregnates a paper base material with an epoxy resin emulsion using water as a dispersion medium and dries it, and then impregnates and dries an epoxy resin varnish to form a prepreg. The present invention relates to a method for manufacturing a laminate, which is characterized by stacking several sheets and heating and pressurizing them.

る。これは、積層板の耐熱性、耐水性等の向上を図るに
は積層板を構成する各プリプレグである紙エポキシ基材
の耐熱性、耐水性の向上を図る必要があるためである。In the present invention, an epoxy resin emulsion containing water as a dispersion medium is used as the undercoat resin, and is impregnated into the paper base material. This is because in order to improve the heat resistance, water resistance, etc. of the laminate, it is necessary to improve the heat resistance and water resistance of the paper epoxy base material, which is each prepreg forming the laminate.
ところで、フェノール樹脂を下塗り樹脂に用いる場合、
紙基材層での吸水が大きくなっている。また吸水後の耐
熱試験による脹れ等もエポキシ樹脂層で起こることは少
なく、はとんど紙基材層で起こっている。By the way, when using phenolic resin as an undercoat resin,
Water absorption in the paper base layer is large. In addition, swelling and the like due to heat resistance tests after water absorption rarely occur in the epoxy resin layer, but mostly in the paper base layer.
これはフェノールが水溶性であるため吸水性が大きいこ
と、また反応が脱水縮合反応であるため、水が発生しや
すいこと等に起因している。This is due to the fact that phenol is water-soluble and therefore has high water absorption, and that the reaction is a dehydration condensation reaction, so water is easily generated.
そこで、本発明では、紙基材の下塗り樹脂として上記の
如くエポキシ樹脂を用いている。これは、エポキシ樹脂
自体フェノール樹脂と比べ、電気的。Therefore, in the present invention, an epoxy resin is used as the undercoat resin for the paper base as described above. This makes epoxy resin itself more electrically conductive than phenolic resin.
化学的特性等に優れているとともに、これを水エマルジ
ヨン化することにより、紙への含浸性が大幅に良好とな
るからである。This is because it has excellent chemical properties and the like, and when it is made into a water emulsion, its impregnating properties into paper are significantly improved.
また、ジシアンジアミドは、一般には溶媒に対して溶解

マルジヨン系エポキシ樹脂の硬化剤としては適している
。Furthermore, although dicyandiamide is generally a substance with low solubility in solvents, it is relatively well soluble in water and is suitable as a curing agent for water emulsion type epoxy resins.
（実施例の説明） 次に本発明を実施例および比較例に基づいて説明する。(Explanation of Examples) Next, the present invention will be explained based on Examples and Comparative Examples.
