Abstract

The invention discloses a reinforcing process of alumina silicate glass. The reinforcing process includes the steps of S1, preheating the alumina silicate glass under 80-100 DEG C for 10-15 minutes; S2, impregnating the preheated alumina silicate glass obtained in S1 in preprocessing liquid of 100-120 DEG C to obtain preprocessed alumina silicate glass, wherein the preprocessing liquid comprises diethanolamine borate, cerous nitrate, amino acid type surfactant and water; S3, performing primary heat preservation on the preprocessing alumina silicate glass obtained in S2 under 300-450 DEG C, using a molten-salt spraying device to spray reinforcing molten salt of 630-680 DEG C to the surface of the surface of the glass, performing secondary heat preservation, and annealing to obtain the reinforced alumina silicate glass. The reinforcing process has the advantages that the alumina silicate glass is impregnated by the preprocessing liquid comprising the diethanolamine borate, the cerous nitrate and the amino acid type surfactant before the reinforcing molten salt is sprayed to the surface of the glass, ion exchanging speed is increased, the penetrating ability of the reinforcing moltensalt is increased, and the surface reinforcing effect of the alumina silicate glass is increased.
