Ceramic tiles meeting the national standard can be prepared by using the polishing ceramic waste with fine particles, wherein the maximum addition of the waste ceramic can reach 40-60%, and the ceramic waste can be introduced to realize low-temperature quick firing of finished products. Secondly, the method is used for preparing sanitary ceramic blanks. The sanitary ceramic waste can be used as a raw material for a blank of sanitary ceramic after crushing and ball milling, but the waste ceramic particles have large particles and high hardness, so that the sanitary ceramic waste is subjected to repeated crushing and ball milling, and low-temperature quick firing is not easy to realize. And thirdly, preparing the porous ceramic. In the high-temperature sintering process of the ceramic waste, uniform closed air holes can be formed inside the material, and the light heat-insulating material, the sound-insulating material, the fireproof material and the like can be prepared by utilizing the high-temperature foaming principle of the material. Fourth, for preparing the complete wasteThe material is permeable brick. The waste porcelain granules are used as raw materials, communicated pore structures are easily formed in the compression molding process, rainwater permeation is facilitated, and the water permeable brick for gardens can be prepared. The method has high utilization rate of the waste ceramics, and the utilization rate can reach 70-80%. And fifthly, preparing the cement-based material. SiO in ceramic waste2And Al2O3Has the characteristics of a pozzolanic mixed material, so that the cement can be produced as a cheap raw material.
The existing sanitary ceramics prepared by utilizing ceramic waste materials have poor mechanical properties and the water absorption property is required to be improved.

Scanning electron micrographs of the samples were determined using a scanning electron microscope, model EVO18, ZEISS, Germany.
The mechanical properties of the samples were determined by an universal mechanical tester model Instron5567, Instron, USA.
Testing of Water absorption:
the water absorption (W) is the ratio of the mass of water absorbed by all open pores of a sample of the material in distilled water at a specified temperature and time to the dry mass of the sample at 110 ℃ and is measured as follows:
the sample is dried at 110 ℃ for 3h in a drying cabinet, cooled to room temperature and then weighed (to the nearest 0.01g) on an electronic balance and recorded as M1；
Placing the sample in a beaker, immersing the sample in distilled water, heating the sample to boil, boiling the sample for 3 hours without contacting the sample with the wall of the beaker, and cooling the sample to room temperature to obtain a saturated sample;
the saturated sample was weighed to the extent that the mass of the saturated sample immersed in distilled water was 0.01g, and the apparent mass M of the saturated sample was obtained2；
Carefully wiping off the dripping on the surface of the saturated sample with a towel saturated with distilled water (the immersion liquid in the macropore cannot be sucked out), and obtaining the mass M of the saturated sample3. Finally, using the formula W ═ M [ (- ]3-M1)/M1]X 100%, the water absorption of the sample can be obtained.
Testing of flexural strength:
the test adopts an Instron5567 material universal tester to test the breaking strength at normal temperature. The dimensions of the test specimens were: 3mm × 4mm × 40mm, a loading speed of 0.5mm/min, and a bending strength (σ:) measured by a three-point bending resistance (bending resistance) methodf) The calculation formula of (2) is as follows: sigmaf＝1.5×PL/bh2. In the formula sigmafBending strength, MPa; b and h are respectively the width and height of the fracture section of the sample, and are mm; p is the maximum load when the sample breaks, N; l is the span between the supports, mm, and this experiment was taken to be 30 mm.
The XRD patterns of the waste ceramics were measured, and the results are shown in fig. 1. The SEM images of the waste ceramics were tested and the results are shown in fig. 2. The XRD pattern of the sanitary ceramic prepared in example 1 was measured, and the result is shown in fig. 3. The SEM picture result of the sanitary ceramic manufactured in test example 1 is shown in fig. 4. FIGS. 1 and 2 are XRD and SEM images of waste ceramics respectively, and mainly represent the phases and the shapes of waste ceramics. Fig. 3 and 4 are XRD and SEM images of the prepared ceramic body, respectively, and it can be seen from the XRD images that the main crystal phases of the ceramic body are quartz and mullite, and the peak strength of the mullite crystal phase is significantly higher than that of fig. 1, indicating that the mullite crystal phase content is increased, and the mullite is favorable for enhancing the strength of the ceramic body, so that the mullite crystal phase is increased, and the overall strength of the ceramic body is favorably increased. As can be seen from fig. 4, the sample surface has no significant pores, which indicates that under the condition of controlling the optimal formulation and the optimal process, a compact porcelain blank without significant pores can be prepared.
The flexural strength and water absorption of the sanitary ceramics prepared in example 1, example 11 to example 15 were measured, and the results are shown in fig. 5. As can be seen from FIG. 5, the sanitary ware prepared in examples 11 to 15 has better bending strength, lower water absorption and avoids dampness, i.e. when the waste ceramic accounts for 21.05 to 34.78 weight percent of the solid raw material, the prepared sanitary ware has excellent bending strength, lower water absorption and avoids dampness.
As can be seen from FIG. 5, the sanitary ware prepared in examples 12 to 14 has better bending strength, lower water absorption, and avoids moisture, i.e., the sanitary ware prepared has better bending strength and lower water absorption when the waste ceramic accounts for 25 to 31.82 percent of the weight of the solid raw material.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
