Abstract

PURPOSE: A base material of paper is impregnated with an early-stage polycondensate of butylphenol-modified phenolic resin, laminated with paper impregnated with, e.g., a phenolic resin and hot-pressed to produce the objective laminated sheets with high mechanical strength and processbility such as good cold punching.
CONSTITUTION: A base material of paper such as kraft paper is impregnated with an early-stage polycondensate of butylphenol-modified phenol-formaldehyde resin, which is obtained by reaction of phenol containing 15W35wt% of butylphenol with formaldehyde in the presence of an alkaline catalyst and dried. The dried product is laminated with paper sheets impregnated with a phenoic and/or epoxy resins and dried and hot-pressed to produce the objective laminated sheets.
EFFECT: Improved electric properties are given.
USE: Copper-plated laminate for electric and mechanical purpopses.
