실험 절차

Moist silicic acid gel containing equivalent to about one mol of silicon dioxide with a pH of 6.5 to 8, is mixed with one mol of melamine, heated to 70° to 260° C., while mixing, for 20 to 60 minutes, thereby producing a white, fine, granular compound, melamine silicate. The said melamine silicate is added to about 5 mols of aqueous formaldehyde, heated to 70° to 120° C. for 30 to 90 minutes; the melamine silicate goes into solution; the solution is filtered; and about 5% to 15% of the said silicic acid gel is filtered out. The said solution is heated until the melamine silicate reacts chemically with the formaldehyde to produce white granules of poly (formaldehyde melamine silicate) resin. On further heating, the said resin melts and produces a soft pliable resin.
