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 As shown, including the following steps:

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

[0038] a. Weigh the raw material components according to the weight percentage of the green body: SiO 2 60~65%, Al 2 O 3 20~23%, CaO0~1%, MgO 0~0.8%, K 2 O 2~4%, Na 2 O 0.1~0.5%, Fe 2 O 3 +TiO 2 1 to 2%, the remaining auxiliary raw materials 1 to 2.5%, the remaining auxiliary raw materials include alkaline noodles, water glass, dolomite; will contain the above-mentioned raw material components or the ridged raw materials containing the above-mentioned raw materials components, plastic clay raw materials and the rest Auxiliary raw materials are mixed, add appropriate amount of water and pulverize by ball milling. When the particle size reaches 10μm, which accounts for 67-72%, it will be discharged and milled and then de-ironed, sieved, refined and aged to make slurry (concentration 350±2g / 200mL) , Pulp temperature is 30±5℃, viscosity V 0 60±5s / 100mL, ...

Embodiment 2

[0047] According to the technical scheme of Example 1, according to the chemical composition of the formula in Table 1, the corresponding proportions of kaolin, water-washed china clay, water-washed ball clay, potash feldspar, hard kaolin, pyrophyllite, etc. are selected as ingredients; then an appropriate amount of water is added and ball milled When the particle size reaches 10μm, 67%~70%, the slurry will be discharged and milled, iron removed, sieved, refined and aged to make a slurry with excellent performance, and then grouted into the plaster model. After pulping, consolidation, and demolding, it is dried in a drying room at a temperature (25-55)°C and a humidity (5-75)% to a moisture content below 5% to obtain a sanitary ceramic green body.

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 specifically relates to a sanitary ceramic red nano glaze slurry and a preparation method and application thereof. Background technique [0002] Chinese red glaze materials have been used in the production of low-temperature fast-fired and multiple-fired ceramics. However, in the production process of sanitary ceramics, due to its special modeling 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 color distortion or even loss of color, poor surface gloss, uneven and smooth glaze. Since the early 1990s, industry personnel 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 not pure, or non-ceramic materials are used, which has a big gap wi...
