温度で２〜３時間加熱焼成して該接着剤を硬化させる。The heat insulating material according to the manufacturing method of the present invention is obtained by impregnating a glass fiber fabric with a silicone resin, drying it with hot air, cutting it into a flat plate shape, laminating a plurality of these sheets and forming a TM laminate by hot press molding, Next, after drying the laminate with hot air, the laminate is punched out to form a heat insulating base material according to the intended use, and the heat insulating base material is bonded with a phenolic cashew knitting material, which is a type of thermosetting resin adhesive. The sample is immersed in the adhesive for 1 hour to be impregnated with the adhesive, dried, and then heated and baked at a temperature of 180° C. to 200° C. for 2 to 3 hours to harden the adhesive.
