含浸させ難い、問題があった。Conventionally, the continuous manufacturing method for laminated plates was disclosed in Japanese Patent Application Laid-Open No. 56-13136.
As described in , a resin-impregnated base material is obtained with a length that allows one-time impregnation with resin varnish, and the required number of resin-impregnated base materials are stacked and continuously molded. There was a problem that it was difficult to impregnate with resin.

方法を提供することにある。As described in the related art section, a uniform resin-impregnated base material cannot be obtained by impregnating the resin once in continuous molding of a laminate. The present invention has been made in view of the above-mentioned problems in the conventional technology, and its purpose is to obtain a resin-impregnated base material uniformly impregnated with resin and to provide a method for manufacturing a laminate with excellent performance. It's about doing.

細な説明する。The present invention involves contact impregnation with a resin varnish from the bottom surface of a long strip-shaped base material, then stacking the required number of resin-impregnated base materials with resin varnish impregnated on one side from the top surface, and then further applying metal foil to the top and/or bottom surfaces. Because the manufacturing method of the laminate is characterized by continuous lamination molding of the laminate provided with the laminate, even if it is impregnated twice, the first time is contact impregnation and does not cause unreasonable distortion to the base material. In addition, the built-in air in the base material can be discharged from the bottom to the top without any resistance, and in combination with double impregnation, the base material can be uniformly impregnated with the resin.The water invention will be described in detail below.

Synthetic fiber cloth, synthetic fiber nonwoven fabric, asbestos vapor, cotton cloth, etc. are used, but it is preferable to use glass cloth or paper, which has a large thickness adjustment effect. Resin varnish/
For binding, unsaturated polyester resins, vinyl ester resins, epoxy resins, phenol resins, polyimide resins, etc. may be used alone, modified products, or mixtures thereof. Note that the primary and secondary impregnating resins may be the same,
Moreover, it may be unusual and arbitrary.

Impregnation methods such as transfer and coating are used, and although not particularly limited, it is desirable to use a casting method because it facilitates reducing the amount of built-in air in the base material. Metal foils include copper, aluminum, iron, stainless steel, nickel, zinc, brass, etc.
If a composite foil is used, an adhesive layer can be provided on one side of the metal foil to improve adhesiveness, if necessary.
