行なわれて偽る。Conventionally, when producing prepreg by impregnating and drying varnish into decorative laminate substrates, laminate board substrates, and multilayer wiring board substrates such as paper, cloth, and woven glass fabric, the substrate is placed in an impregnating tank containing varnish. The base material is impregnated with varnish, but the air contained in the base material is impregnated, and as a countermeasure to this, it is possible to install an ultrasonic generator in the varnish tank.

ことにある。As described in the conventional technology section, even if the base material is impregnated with varnish using a varnish bath equipped with an ultrasonic generator, which is currently widely used, the cavitation created by the ultrasonic generator will cause air bubbles to form on the road. The effect will be reduced because it will remain. The present invention has been made in consideration of the above-mentioned problems in the prior art, and its purpose is to provide a method for impregnating a base material with varnish that can obtain a resin-impregnated base material without air bubbles. be.

発明の詳細な説明する。The present invention is a method of impregnating a base material with varnish, which is characterized in that the base material is immersed in a solvent tank equipped with an ultrasonic generator, and then introduced into a varnish tank to impregnate the base material with varnish. The air contained in the varnish is quickly released into a low-viscosity solvent such as water or a solvent, and the air bubbles that are released are immediately released into the air from the low-viscosity solvent, so even when varnish is impregnated, there are no air bubbles. The present invention will now be described in detail.

る。The solvent used in the invention may be any solvent as long as it is compatible with the varnish used, and generally water or organic solvents such as water, methyl alcohol, ethyl alcohol, acetone, cyclohexanone, styrene monomer etc. are used, as long as they are compatible with the varnish used. can be used. The ultrasonic generator may be any device that generates ultrasonic waves, such as an ultrasonic horn, and is not particularly limited. If necessary, add a solvent such as water, methyl alcohol, acetone, cyclohexanone, styrene, etc. to polyimide resin, polysulfone, polybutadiene, fluorinated resin, polybutylene terephthalate, polyether ether ketone, etc. or a mixture thereof. ffs KaLt Tawanis, the base material is glass,

A base material such as woven or non-woven fabric made of organic synthetic fibers such as polyvinyl alcohol and acrylic, or natural fibers such as cotton, paper, marito, etc. After immersing the base material in the solvent bath equipped with the ultrasonic generator, the base material may be immersed as it is or air-dried. Or after drying, the page is led to a varnish bath,
By impregnating the base material with the ζ varnish, it is possible to obtain a resin-impregnated base material in which the core of the base material is impregnated with resin.
