Problems solved by technology

[0002] High-alumina ceramics are one of the representative types of porcelain, which have good whiteness, high strength and high production yield, but due to the high content of aluminum, the production cost is also high
At the same time, the uncertainty of the order for ceramic firing leads to the uncertainty of the production output. The speed of the trolley in the tunnel kiln often changes. The melting range of the glaze is too small to adapt to this change, which affects the expansion of the glaze. Coefficient, pinholes, pores, etc. appear

Abstract

The invention relates to high zinc-boron fritted glaze. The high zinc-boron fritted glaze is prepared from the following raw materials in parts by weight: 82 to 91 parts of frit, 9 to 12 parts of nepheline syenite, 2 to 4 parts of wollastonite, 3 to 6 parts of lithium cornish stone, 0 to 5 parts of quartz, 0 to 7 parts of periclase, 0 to 5 parts of cryolite, 0 to 9 parts of kaolin and 0 to 5 parts of aluminium oxide; the frit is prepared from the following components in parts by weight: 45 to 51 parts of willemite, 38 to 43 parts of borax, 12 to 15 parts of calcium borate, 13 to 16 parts of vesuvianite, 4 to 8 parts of scapolite, 3 to 7 parts of potassium feldspar and 1 to 4 parts of talc. A high zinc-boron fritted glaze product prepared from the raw materials disclosed by the invention has the advantages of good whiteness and attractiveness, smooth glaze, high hardness and good acid-alkali resistance; the rate of a finished product reaches 98 percent; the cost of the raw materials is greatly reduced while the mass of the high zinc-boron fritted glaze is comparable to that of high-aluminum durable porcelain, so that the high zinc-boron fritted glaze has powerful market competitiveness.

Description

technical field [0001] The invention relates to the technical field of daily-use ceramics, in particular to a high-zinc-boron frit glaze and a preparation method thereof. Background technique [0002] High-alumina ceramics are one of the representative types of porcelain, which have good whiteness, high strength, and high production yield. However, due to the high content of aluminum, the production cost is also high. At the same time, the uncertainty of the order for ceramic firing leads to the uncertainty of the production output. The speed of the trolley in the tunnel kiln often changes. The melting range of the glaze is too small to adapt to this change, which will affect the expansion of the glaze. coefficient, pinholes, pores, etc. appear. Contents of the invention [0003] The purpose of the present invention is to overcome the shortage of raw materials in the existing ceramic production, and to provide a high-zinc-boron frit glaze and a preparation method thereof....
