[0016] A preparation method of mineral composite nano-titanium dioxide ceramic glaze opacifying additive includes the following specific steps:
[0017] (1) Add 50g of tetrabutyl titanate dropwise to 75g of absolute ethanol, mechanically stir at 1000 rpm for 30 minutes to obtain solution A for use; mix 25g of diethanolamine with 37.5g of deionized water , And form solution B after stirring evenly;
[0018] (2) Slowly add solution A to solution B. After the addition is complete, a mixed solution is obtained. Then add 90g of white diatomaceous earth, mechanically stir at 1000 rpm for 2 hours and then stand for 9 hours. Finally Put the prepared product in an oven and dry at 100°C for 60 minutes to obtain a nano-titanium dioxide white diatomaceous earth composite;
[0019] (3) Mix the nano-calcium carbonate and the step (2) nano-titanium dioxide white diatomaceous earth compound with equal mass, stir and disperse evenly, add 1L deionized water, put it in an ultrasonic oscillator, ultras...
