Embodiment 1
[0023] An admixture for cement clinker production is composed of the following raw materials in percentage by weight: 1% ferric chloride, 2% ferric sulfate, 5% urea, 3% glycerin, 8% compound sodium sulfate, 6% ammonium nitrate, and The amount is water.
[0024] The composite sodium sulfate is obtained by mixing sodium carbonate and nano-boron nitride according to a mass ratio of 1:1; the preparation method of the nano-boron nitride is: dispersing 6g of hexagonal nano-boron nitride in 200mL of N-formaldehyde Add 5-10ml of N,N-dimethylethanolamine, 50ml of 5M NaOH solution to pyrrolidone, stir at 80°C for 12h, sonicate for 4h, centrifuge at 6000rpm for 20min, wash the lower precipitate with absolute ethanol, and dry in vacuum for 8h to obtain nano boron nitride.
[0025] The nano-boron nitride of the present invention adopts commercially available finished hexagonal boron nitride, which is purchased from Liaoning Boda Technology Co., Ltd.
[0026] The purity of N,N-dimethyleth...
Embodiment 2
[0032] An admixture for cement clinker production, which is composed of the following raw materials in weight percentage: 2% ferric chloride, 1% ferric sulfate, 6% urea, 4% glycerin, 6% compound sodium sulfate, 8% ammonium nitrate, and the balance for water.
[0033] The composite sodium sulfate is obtained by mixing sodium carbonate and nano-boron nitride according to a mass ratio of 1:1; the preparation method of the nano-boron nitride is: dispersing 6g of hexagonal nano-boron nitride in 200mL of N-formaldehyde Add 6ml of N,N-dimethylethanolamine, 50ml of 5M NaOH solution to pyrrolidone, stir at 80°C for 12h, sonicate for 4h, centrifuge at 6000rpm for 20min, wash the lower precipitate with absolute ethanol, and dry it in vacuum for 8h to obtain nano-nitrogen Boron.
[0034] The nano-boron nitride of the present invention adopts commercially available finished hexagonal boron nitride, which is purchased from Liaoning Boda Technology Co., Ltd.
