Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with examples, which are only preferred implementations of the present invention, and are not limitations of the present invention.

[0026] The mineral raw material chemical composition that following embodiment adopts is:

[0027]

[0028] Examples 1 to 3, comparative example 1, and the raw material composition of each frit glaze are specifically shown in the table below.

[0029]

[0030] The preparation method of titanium dioxide frit glaze is as follows: weigh 13 tons of powder according to the ratio in the above table, mix it in the mixer for 20-25 minutes, stir evenly, and pack it into 1 ton bags; Carry out high-temperature firing at a temperature of 1510~1540°C; high-temperature water quenching, and pack into 50 kg packages.

[0031] The titanium white frit glaze of Example 2 and the comparative example and the existing ordinary titanium white frit glaze are applied to porcelain produc...

Abstract

The invention discloses titanium white fritted glaze which is prepared from, by mass, 2-3% of Na<2>O, 4-5% of K<2>O, 0-1% of MgO, 16-18% of CaO, 6-8% of Al<2>O<3>, 56-62% of SiO<2>, 0.5-1.2% of P<2>O<5> and 8-10% of TiO<2>. The invention further discloses a preparation method of the titanium white fritted glaze. According to the titanium white fritted glaze, a defined amount of apatite is added, a phosphorus split phase is formed in the glaze at a high temperature, and the glaze emulsion turbidity is improved through the refractive index difference between liquid phrases; meanwhile, on the premise that a good glaze surface is guaranteed, the consumption of titanium dioxide is lowered, and the emulsion turbidity, whiteness and fatness can be further improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a titanium white frit glaze for ceramic wall tiles and a preparation method thereof. Background technique [0002] Frit glaze, is a composition for use on ceramic surfaces. At present, most of the glazed wall tiles in my country use high-titanium titanium dioxide opacity glaze as the bottom glaze. The high content of titanium dioxide not only plays a good opacification effect, but also improves the whiteness and smoothness of the glaze. . However, the cost of the titanium dioxide base glaze is high due to the high cost of the added titanium dioxide raw materials, and the price is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a titanium white frit glaze, by adding a certain amount of apatite, phosphorus phase separation is formed in the glaze at high temperature, and the refractive index difference ...
