Problems solved by technology

There are also some products on the market, but either the color is impure or non-ceramic materials are used, which has a large gap with pure ceramic materials in terms of wear resistance, stain resistance, service life, and environmental protection.

Embodiment 1

[0036] Such as figure 1 shown, including the following steps:

[0037] (1) Preparation of sanitary ceramic green body: including:

[0038] a. Weigh the raw material components according to the component weight percentage of the green body: SiO 2 60-65%, Al 2 o 3 20~23%, CaO0~1%, MgO0~0.8%, K 2 O2~4%, Na 2 O0.1~0.5%, Fe 2 o 3 +TiO 2 1-2%, the remaining auxiliary raw materials 1-2.5%, the remaining auxiliary raw materials include alkali flour, water glass, dolomite; Auxiliary raw materials are mixed, adding appropriate amount of water and finely crushed by ball milling. When the particle size reaches 10μm, accounting for 67-72%, the slurry is discharged from the mill, and then iron is removed, sieved, refined and stale to make slurry (concentration: 350±2g / 200mL , slurry temperature is 30±5℃, viscosity V 0 60±5s / 100mL, viscosity V 30 is 110±5s / 100mL, yield value is 15±4);

[0039] b. Grouting the above mud in a gypsum model, drying the slurry at a temperature of 25 t...

Embodiment 2

[0047] According to the technical scheme of embodiment 1, select kaolin, washed china clay, washed ball clay, potassium feldspar, hard kaolin, pyrophyllite, etc. in corresponding proportions by the chemical composition of the formula in table 1 to carry out batching; add an appropriate amount of water through ball milling When the particle size reaches 10μm, accounting for 67% to 70%, the slurry is released and milled. After iron removal, sieving, refining, and aging, the slurry with excellent performance is made, and then grouted in the plaster model. After pulping, consolidation and demoulding, dry in a drying room at a temperature of (25-55)°C and a humidity of (5-75)% until the moisture content is below 5%, and the sanitary ceramic green body is obtained.

Abstract

The invention discloses a bright red nanometer glaze slip material for ceramic sanitary wares, as well as a preparation method and application of the bright red nanometer glaze slip material. The bright red nanometer glaze slip material specifically comprises water as a medium, and the following components in percentage: 20-25% of feldspar, 40-45% of quartz, 16-20% of calcium carbonate, 2-3% of dolomite, 3-5% of zinc oxide, 2-4% of kaolin, 2-5% of nanometer zirconium, 3.5-6% of nanometer aluminum oxide, 9-12% of 060 bright red chromophoric materials, 1-3% of Z309 claret chromophoric materials and an appropriate amount of CMC for ceramics. The bright red nanometer glaze slip material disclosed by the invention is resistant to high temperature and can bear long-time high-temperature calcination, so that the application of bright red nanometer glaze for the ceramic sanitary wares in the production of the ceramic sanitary wares comes true, and the defects that color becomes black and pigments are volatilized after high-temperature calcination are overcome.

Description

technical field [0001] The invention belongs to the technical field of sanitary ceramics, and in particular relates to a sanitary ceramic scarlet nano-glaze slurry and a preparation method and application thereof. Background technique [0002] China red glaze has been used in the production of low-temperature fast-firing and multiple-firing ceramics. However, in the production process of sanitary ceramics, due to its special shape structure and harsh firing system, the firing temperature is as high as 1250 degrees. The cycle time is as long as 16-20 hours, causing problems such as color distortion or even loss of color, poor surface gloss, and uneven and smooth glazed surface. Since the early 1990s, people in the industry have been studying the application of Chinese red glaze in sanitary ceramics and published some related papers, but few mature products have appeared. There are also some products on the market, but either the color is impure or non-ceramic materials are u...
