Embodiment 1
[0071] A ceramic plate for a cooktop is composed of a green body and a glaze; slots for splicing are provided on both sides of the green body.
[0072] The preparation method of the ceramic plate for the cooktop comprises the following steps:
[0073] 1) Add water to 2kg of kaolin to make a slurry, slowly add 0.5kg of epoxy resin toughening emulsion containing modified bamboo fiber, stir thoroughly for 0.5h, dry, calcinate at 200°C for 0.5h, pulverize, and pass through a 200-mesh sieve to obtain Modified kaolin;
[0074] 2) Mix the modified kaolin in step 1) with 1kg of phosphogypsum, 0.8kg of quartz, 0.5kg of feldspar, and 0.3kg of lime, and ball mill to obtain a ceramic slurry;
[0075] 3) Dry or dry the ceramic slurry in step 2) and press it into a ceramic slab body;
[0076] 4) Dry the ceramic slab body in step 3) in a drying kiln until the water content is 3%, raise the temperature of the green body to 1000°C at 10°C / min, keep it warm for 2 hours, and then cool it down ...
Embodiment 2
[0092] A ceramic plate for a cooktop is composed of a green body and a glaze; slots for splicing are provided on both sides of the green body.
[0093] The preparation method of the ceramic plate for the cooktop comprises the following steps:
[0094] 1) Add water to 3kg of kaolin to make a slurry, slowly add 1kg of epoxy resin toughening emulsion containing modified bamboo fiber, stir thoroughly for 1 hour, dry, calcinate at 250°C for 0.5 hour, crush, pass through a 300-mesh sieve to obtain modified Kaolin;
[0095] 2) Mix the modified kaolin in step 1) with 1.5kg of phosphogypsum, 1.5kg of quartz, 0.8kg of feldspar, and 0.5kg of lime, and ball mill to obtain a ceramic slurry;
[0096] 3) Dry or dry the ceramic slurry in step 2) and press it into a ceramic slab body;
[0097] 4) Dry the ceramic slab body in step 3) in a drying kiln until the water content is 5%, raise the temperature of the green body to 1200 °C at 12 °C / min, keep it for 1 hour, and then cool it down to 700...
