Problems solved by technology

Therefore, shale is particularly suitable for use as a raw material for building ceramics. However, due to its high iron content, it is easy to deform when fired, the production quality is difficult to control, and the product has poor color and whiteness. It has not been able to be used in sanitary ceramics. production field

Embodiment 1

[0038] Shale sanitary ceramics are prepared by the following steps:

[0039] (1) Raw material ratio: Weigh and mix according to the percentage of green body raw materials.

[0040] The component distribution ratio of green body raw materials: Boai clay 15wt%, bauxite 8wt%, white gangue 10wt%, gray gangue 5wt%, Yuanan soil 2wt%, black mud 8wt%, shale 30wt%, quartz 10wt%, feldspar 12wt%.

[0041] (2) Ball milling: Put the weighed green body raw materials into the ball mill according to the ratio of material: ball: water = 1:2.3:0.7 for ball milling; ball milling to 325 mesh sieve residue is less than 1, and pass through 80 mesh sieve to send Go to the stale pulp pool for stale;

[0042] (3) Stale: the mass fraction of water in the mud in the stale pool is 30-32%, and the specific gravity is 1.75-1.77. After 12 days of stale, the low-speed mixer will continue to stir during the stale;

[0043] (4) Grouting molding: micro-pressure grouting method is adopted, the grouting time i...

Embodiment 2

[0051] On the basis of embodiment 1,

[0052] Step (6) In the glaze processing, replace it with a low-temperature opacified glaze. The formula is: Boai clay 10 wt%, talc 20 wt%, feldspar 35 wt%, quartz 10 wt%, zirconium silicate 20 wt%, zinc oxide 5 wt% .

[0053] Other parts are identical with embodiment 1.

Embodiment 3

[0055] On the basis of embodiment 1,

[0056] In step (1), the proportion of green body raw materials is replaced by: Boai clay 15 wt%, bauxite 8 wt%, white gangue 10 wt%, gray gangue 5 wt%, Yuan'an soil 1 wt%, black mud 5 wt% , shale 40 wt%, quartz 10 wt%, feldspar 6 wt%.

[0057] Other parts are identical with embodiment 1.

Abstract

The invention discloses a sanitary shale ceramic and a preparation method thereof. The blank of the sanitary shale ceramic comprises the following raw materials: 10-20wt% of Boai clay, 5-15wt% of bauxite, 5-15wt% of white gangue, 5-15wt% of ash waste rock, 1-5wt% of Yuan'an clay, 5-15wt% of black mud, 5-40wt% of shale, 10-20wt% of quartz and 5-25wt% of feldspar. As shale is adopted as a main raw material, the sanitary ceramic with excellent properties are made, the material cost is effectively reduced, meanwhile the product quality is ensured, the sintering temperature is low in the preparation process, energy consumption is effectively reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sanitary ceramics. Background technique [0002] Sanitary ceramics refer to ceramic products used in kitchens, bathrooms, etc., which have high requirements on the formability, mechanical strength and surface whiteness of ceramics. In the prior art, building sanitary ceramics are mainly prepared by high-temperature firing of raw materials such as clay, feldspar and quartz. At present, the domestic production of sanitary ceramics is huge and is still growing. The annual consumption of ceramics The raw materials are also pretty amazing. At the same time, in order to ensure the yield and color quality of products, especially for the whiteness of green bodies, the quality of ceramic raw materials used by manufacturers is also getting higher and higher, which makes the consumption of high-quality ceramic raw materials continue to increase, and individual high-quality raw materials It is nearly exhausted, suc...
