8. A manufacturing process of high-hardness glazed domestic ceramic prepared by introducing graphene, which meets any one of requirements 1-4, comprises the following specific steps:
step 1, preparing a blank, preparing a ceramic blank body, trimming and molding the prepared ceramic blank body, and bisque firing the molded blank body at 750-810 ℃ to obtain a bisque;
step 2, preparing glaze, wherein when preparing the high-hardness glaze, feldspar, quartz, lithium porcelain stone, bone meal, alumina, barium carbonate, zinc and zirconium carbonate are weighed according to the weight parts of the raw materials of the high-hardness glaze, added into a wet ball mill for ball milling for 3-4 hours, modified graphene is added into the slurry, and the slurry is continuously stirred for 4-5 hours;
step 3, glazing, namely, after the blank body is dried, applying high-hardness glaze on the surface of the ceramic biscuit, wherein the thickness of glaze slip is 0.8-1.0 mm;
and 4, sintering, namely placing the blank containing the glaze into a kiln after the blank is dried, and sintering and forming at the sintering temperature of 1300-1310 ℃ to obtain the high-hardness glaze domestic ceramic.
9. The process for manufacturing high-hardness glazed domestic ceramic by introducing graphene as claimed in claim 7, wherein before the glaze is manufactured in the step 2, modified graphene is prepared, and the steps are as follows: weighing and mixing graphene, magnesium oxide and aluminum oxide to obtain a graphene mixture, calcining the graphene mixture at the temperature of 110-120 ℃ for 30-40 minutes, and adding the calcined graphene mixture into a ball mill for grinding.
10. The process for manufacturing high-hardness glazed domestic ceramic by introducing graphene as claimed in claim 7, wherein the process comprises the following steps: the firing control in step 4 is as follows: putting the ceramic body into a tunnel kiln,
a preheating section: raising the temperature from normal temperature to 800 ℃ over 1-2 hours;
a temperature rising section: the temperature of the kiln is continuously increased to 1000 +/-10 ℃ after 2-3 hours;
and (3) a heat preservation stage: the temperature of the kiln is raised to the firing temperature within 1-2 hours, and the temperature is kept for 1-2 hours after the firing temperature is reached;
a cooling section: the temperature of the kiln is reduced to 800 +/-10 ℃ after 0.5-1 hour;
secondary heating: the temperature of the kiln is raised to 1000 +/-10 ℃ after 20-40 minutes;
and (3) cooling: and cooling the kiln to the normal temperature after 3-5 hours.
