実験手順
Moist silicic acid gel containing about 1 mol of slicon dioxide and one mol of malamine are mixed, sodium carbonate is added until the pH is 8 to 10.5, then heated to 70° to 260° C. for 20 to 90 minutes, while agitating, thereby producing fine granules of melamine silicate. The said melamine silicate is added to about 2 mols of aqueous formaldehyde, heated to 70° to 150° for 30 to 120 minutes, while agitating, and the melamine silicate goes into solution. On further heating, a white, soft, granular resin, poly (formaldehyde melamine silicate) is produced.
