PROCESS FOR PRODUCING GLASS WOOL MOLDING, GLASS WOOL MOLDING AND VACUUM INSULATION MATERIAL

摘要

It is an object of the present invention to provide a glass wool molded product, which has handling ability equivalent to that of a glass wool molded product molded using a binder, although it is molded without using such binders, and which can be applied as a core of a vacuum heat insulation material, a building material, a heat insulation material used in automobiles, etc., in various fields. A method for producing a glass wool molded product comprising processing a glass material into fibers so as to obtain a glass wool, gathering such glass wools to form a glass wool mat, and subjecting the glass wool mat to press molding, wherein the above described press molding is carried out, while supplying water so that the water content of the above described glass wool mat becomes 0.1% to 7,0% by mass, and while maintaining a temperature between 250°C and 450°C.
