Ceramic glaze and preparation method thereof

[0034] A ceramic glaze made of the following raw materials by weight: 35 parts of nano-silica, 55 parts of kaolin, 15 parts of albite, 5 parts of magnesium oxide, 5 parts of sodium oxide, 25 parts of dolomite, 25 parts of limestone, 3 parts of pigments and fillers, 15 parts of modified additives, 55 parts of deionized water;

[0035] The ceramic glaze is made by the following method:

[0036] Step S1. Activation of kaolin: (a) Put the kaolin in a muffle furnace at 350°C for 1 hour, then add it to 100mL of 10% sodium chloride solution and heat it in a water bath at 70°C for 2 hours; (b) Add 50mL of 20% to the sodium chloride solution Sodium hydroxide solution, heated to 80°C, sonicated, and stirred for 20 min; (c) Filter, put the activated kaolin in a beaker, rinse with deionized water until the solution is neutral, filter again, and place the kaolin at 80 After drying for 2 hours in a drying oven at ℃, grind and pass through a 50-mesh sieve;
