Problems solved by technology

[0002] Enamel products are widely used in all aspects of life, but the enamel of the prior art is a kind of environmental protection ceramic glaze disclosed in the invention patent application of CN102372501A as the application publication number, which includes the following composition, and its mass fraction is: SiO 2 50-60%, A1 2 o 3 5-10%, CaO3-8%, ZnO5-10%, K 2 O2-4%, Na 2 O1-4%, B 2 o 3 2-7%, La 2 o 3 0.3-2%, also contains MgO, BaO and ZrO 2 , its total addition amount is ≤15%. This kind of ceramic glaze has poor performance in high and low temperature resistance. In winter, ceramics are easy to be frozen and cracked, and their high temperature resistance is also poor.

Abstract

The invention relates to porcelain glaze and in particular relates to high and low-temperature resistant porcelain glaze for enamel. According to the technical scheme, the highnd low-temperature resistant porcelain glaze for enamel is prepared from the following raw materials in parts by weight: 22-38 parts of sodium silicate with the modulus of 2-3.8, 11-19 parts of aluminum oxide, 10-20 parts of manganese dioxide, 6-9 parts of palladium oxide, 6-9 parts of high-boron calcium borate, 23-29 parts of lead sulfate, 2-4 parts of talc, 7-13 parts of calcium carbonate, 8-12 parts of barium sulfate, 12-19 parts of zinc sulfate and 2-9 parts of titanium oxide. The high and low-temperature resistant porcelain glaze has excellent ultralow-temperature resistance and high-temperature resistance.

Description

technical field [0001] The invention relates to a ceramic glaze, in particular to a high and low temperature resistant enamel material for enamel. Background technique [0002] Enamel products are widely used in all aspects of life, but the enamel of the prior art is a kind of environmental protection ceramic glaze disclosed in the invention patent application of CN102372501A as the application publication number, which includes the following composition, and its mass fraction is: SiO 2 50-60%, A1 2 o 3 5-10%, CaO3-8%, ZnO5-10%, K 2 O2-4%, Na 2 O1-4%, B 2 o 3 2-7%, La 2 o 3 0.3-2%, also contains MgO, BaO and ZrO 2 , and its total addition amount is ≤15%. This kind of ceramic glaze has poor resistance to high and low temperatures. In winter, ceramics are easily cracked by freezing and have poor high-temperature resistance.
