本発明は、耐湿性、電気絶縁性か優れしかも安価に得ら
れる積層板の製造法１こ関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a laminate that has excellent moisture resistance and electrical insulation properties and can be obtained at low cost.

耐湿性、電気絶縁性が悪いという欠点を有していた。A glass nonwoven fabric base material mixed with cellulose fibers can be obtained at a lower cost than a nonwoven fabric made only of glass fibers, and has greater mechanical strength. However, when a hydrophobic resin such as an ordinary epoxy resin is directly eroded into a cellulose fiber-mixed glass nonwoven base material, and this is then laminated and molded after drying, the resulting laminate has poor moisture resistance and electrical insulation. It had the following drawback.

して得たプリプレグを積層成形するものである。The present invention solves the above-mentioned drawbacks by applying an aqueous solution or an organic solvent solution of a water-soluble epoxy resin containing a silane compound having both an alkoxy group and an epoxy group or an amino group to a glass nonwoven fabric base material mixed with cellulose fibers in advance. After impregnation and drying, the prepreg obtained by impregnating the impregnated base material with an epoxy resin and drying is laminated and molded.

とができる。The alkoxy group (S 1-0
R) is hydrolyzed to become a silanol group (3i-OH), which is bonded to the glass fiber surface of the base material. On the other hand, the amino group or epoxy group is compatible with and bonded to the epoxy resin to be impregnated in the subsequent process and the water-soluble epoxy resin for treating the base material, and furthermore, the water-soluble epoxy resin is bonded to the cellulose fiber-mixed glass nonwoven fabric base. It penetrates into the inside of the cellulose fibers contained in the material, and the epoxy group reacts with the epoxy resin impregnated in the subsequent process, and the cellulose fiber mixed paper increases the tightness between the lath nonwoven fabric base material and the epoxy resin, resulting in moisture resistance and electrical insulation. Improve your sexuality. That is, for an epoxy resin laminate using a fabric base material that is not mixed with cellulose fibers, the silane compound and water-soluble epoxy resin should be used in combination; only in this way can the moisture resistance and electrical insulation of the laminate be improved. I can do it.
