という問題があった。[Prior Art] Conventionally, when a prepreg is manufactured by impregnating a varnish on a base material for a decorative plate such as paper, cloth, glass woven cloth, a base material for a laminated board, a base material for a multilayer wiring board, and a prepreg, the varnish is included. Although the base material is introduced into the impregnation tank and the base material is impregnated with the varnish, the impregnation is performed while the air contained in the base material is included. As a countermeasure against this, it has been attempted to install the entire impregnation tank in the decompression chamber, but there is a problem that a large-scale device is required and the varnish solvent is scattered.

ス含浸方法を提供することにある。As described in the prior art, it is not possible to obtain a resin-impregnated base material without bubbles by the atmospheric pressure impregnation method, and installing the entire impregnation tank in a decompression chamber requires a large-scale device and scatters varnish solvent. To do. The present invention has been made in view of the above-mentioned problems in the prior art, and its object is to obtain a resin-impregnated base material free of bubbles without scattering of varnish solvent without requiring a large-scale apparatus. It is to provide a method for impregnating a varnish into a base material that can be formed.

下本発明を詳細に説明する。The present invention comprises an impregnation tank in which a varnish is stored and a cylindrical coating tank arranged so that the cylindrical lower end thereof is immersed in the varnish, and the liquid surface of the varnish in the cylindrical coating tank is the varnish of the impregnation tank. Using an impregnation device that is higher than the liquid level and has a decompression space inside the top of the cylindrical coating tank, dip the base material in the impregnation tank and the varnish of the coating tank, and then once pass through the depressurizing space in the coating tank. After that, it is again immersed in the varnish of the coating tank and the impregnation tank, and then transferred to the outside of the tank. The present invention will be described in detail below, since it can significantly improve the above-mentioned characteristics and can extremely reduce the scattering of the varnish solvent.

In addition, water, methyl alcohol, acetone, cyclohexanone, a varnish added with a solvent such as styrene as necessary, as the substrate, glass, inorganic fibers such as asbestos and polyester, polyamide, polyvinyl alcohol, organic synthetic fibers such as acrylic and An impregnation tank in which varnish is stored and a tubular coating tank in which the lower end of the tubular shape is soaked in the varnish, which is a base material such as woven cloth, non-woven cloth or paper or mat made of natural fibers such as cotton. The varnish liquid level of this cylindrical coating tank is higher than the varnish level of the impregnation tank. High, using an impregnation device that has a depressurized space inside the top of the tubular coating tank, after immersing the substrate in the impregnation tank and the varnish of the coating tank, after passing through the depressurized space in the coating tank once, It is possible to obtain a resin-impregnated base material impregnated with resin up to the core of the base material by immersing it again in the varnish of the coating tank and the impregnation tank and then transferring it to the outside of the tank.
