PRODUCTION OF GLASS NON-WOVEN FABRIC FOR LAMINATE AND PRODUCTION OF LAMINATE

摘要

PURPOSE:To obtain non-woven fabric giving laminates having a high adhesive force between glass fibers and a resin and having an insulation resistance suppressed in the aging deterioration thereof by removing a sizing agent from the surfaces of the glass fibers, treating the glass fibers with a silane coupling agent and subsequently binding the fibers with a binder. CONSTITUTION:After a sizing agent adhered to the surfaces of glass fibers is removed by a means such a thermal treatment, the glass fibers are treated with a silane coupling agent (preferably an aminosilane coupling agent such as 3-aminopropyltrimethoxysilane or 10-aminoundecyltrimethoxysilane) and subsequently bound with a binder to obtain the objective non-woven fabric.
