Embodiment 1

[0040] The preparation method of a kind of sanitary ceramics as the embodiment of the present invention, described method comprises the following steps:

[0041] (1) 10g of albite feldspar, 23g of Xikeng mud, 10g of black clay, 2g of calcined talc, 30g of ball clay and 15g of waste ceramics were ball milled for 45 minutes until the particle size was 3 μm to 20 μm and used as solid raw materials. 0.3% of water glass is uniformly dispersed in water to make a slurry, and the waste ceramics are crushed by a crusher in advance and ball milled;

[0042] (2) After the slurry was left to stand for 24 hours, the surface of the gypsum mold was wetted and left to stand for 3 hours after grouting, and after demoulding, it was dried at 110°C to obtain a green sample;

[0043] (3) The green body sample was fired in a muffle furnace at a temperature of 1200° C. for 60 minutes to obtain the sanitary ceramics.

[0044] The Xikeng mud of this embodiment is purchased from Chaozhou Sitong Cerami...

Embodiment 2-10

[0047] The difference between embodiment 2-10 and embodiment 1 is: the ball milling time in the step (1), the firing temperature in the step (3) and the holding time under the firing temperature, the component of the solid raw material is: albite feldspar 8g, Xikeng mud 23g, black soil 8g, burnt talc 2g, ball soil 30g, waste ceramics 30g.

[0048] Embodiment 1-Example 9 designed an orthogonal experiment with 3 factors and 3 levels, and the factor levels of the orthogonal experiment are shown in Table 1. Through 9 sets of experiments, the results of orthogonal experiments can be obtained as shown in Table 2, and the range analysis is shown in Table 3.

Embodiment 11

[0057] As a preparation method of sanitary ceramics according to the embodiment of the present invention, the only difference between this embodiment and Embodiment 1 is: (1) 10 g of albite feldspar, 23 g of Xikeng mud, 10 g of black clay, 2 g of burnt talc, and ball clay 30 g and 20 g of waste ceramics were crushed to a particle size of 3 μm to 20 μm as solid raw materials.

Abstract

The invention provides a preparation method of sanitary ceramics, which comprises the steps of (1) pulverizing at least five of albite, western pit mud, quartz, black clay, calcined talc, ball clay, zirconium silicate, calcite and potassium feldspar and waste ceramics to the particle size of 1-30[mu]m to obtain a solid raw material, and uniformly dispersing the solid raw material in water to obtain slurry, wherein the waste ceramic accounts for 15%-40% of the weight of the solid raw material; (2) standing and aging the slurry, and carrying out slip casting, demolding and drying to obtain a green body sample; and (3) firing the green body sample at the temperature of 1100-1300 DEG C to obtain the sanitary ceramic. According to the preparation method of the sanitary ceramic, the waste ceramic is used as a raw material for preparing the sanitary ceramic, so that the waste ceramic is recycled, resources are saved, the bending strength of the sanitary ceramic is remarkably improved, the water absorption rate of the sanitary ceramic is reduced, and moisture is avoided.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a sanitary ceramic and a preparation method thereof. Background technique [0002] In the past ten years, the output of my country's traditional ceramic industry has always ranked first in the world. According to data, the total output of my country's architectural ceramics in 2017 was about 10.146 billion m 2 , The total output of sanitary and daily-use ceramics is about 220 million pieces and 50 billion pieces. On the one hand, the huge production has led to a sharp reduction of natural resources and serious damage to the ecological environment. On the other hand, it has caused a large amount of waste ceramics. According to incomplete statistics, the ceramic waste produced in the construction ceramics industry in my country is as high as 18 million tons every year. . Ceramic waste is an extremely stable material, which can be stored stably for thousands of years in...
