Abstract

The invention belongs to the technical field of enamel glaze preparation, and particularly relates to a high-temperature-resistant compact enamel glaze preparation method, which comprises: 1, enamel frit preparation: mixing 45-65% by mass of silicon dioxide, 10-15% by mass of anhydrous borax, 5-10% by mass of sodium carbonate, 2-6% by mass of lithium carbonate, 2-6% by mass of calcium carbonate, 2-6% by mass of strontium carbonate, and 3-6% by mass of ice crystal to form a batch, melting at 1300 DEG C for 2-3 hours, carrying out water quenching to prepare an enamel material, drying, and sieving with a 200-mesh sieve to obtain enamel frit powder; step 2, preparing enamel glaze slip, namely mixing and ball-milling 40-55% of enamel frit powder, 15-30% of 316 # stainless steel powder, 5.5-10% of clay suspending agent and 25-50% of water in percentage by mass to obtain the enamel glaze slip; and step 3, enamel coating and firing. The enamel coating has excellent high temperature resistance and corrosion resistance and long service life, and the preparation process is simple in requirement, simple and convenient to operate and suitable for industrial production.
