Embodiment 1
[0037] The preparation method of antirust pigment of the present invention:
[0038] 1: Weigh 22.3g of calcium hydroxide [Ca(OH) 2 ], slowly add 200ml of water, stir well until the emulsification is uniform.
[0039] 2: Measure 14ml of concentrated phosphoric acid with a concentration of 85%, slowly add 28ml of water, and stir evenly.
[0040] 3: Slowly add the diluted phosphoric acid to the calcium hydroxide emulsion while stirring. After the dropwise addition, the stirring reaction was continued at normal temperature for 2 hours to stop, and the calcium phosphate intermediate emulsion was obtained.
[0041] 4: Titanium oxysulfate (TiOSO 4 ) 3.2g into 100ml of water, dissolved for later use.
[0042] 5: Weigh 2.86g of calcium hydroxide, add 50ml of water and stir to form an emulsion for later use.
[0043] 6: Add the titanyl sulfate solution prepared in step 4 to the calcium phosphate intermediate emulsion prepared in step 3, mix evenly and drop into the calcium hydroxid...
Embodiment 2
[0046] The preparation method of antirust pigment of the present invention:
[0047] 1: Weigh 30g of calcium carbonate [CaCO 3 ], slowly add 200ml of water, stir well until the emulsification is uniform.
[0048] 2: Measure 14ml of concentrated phosphoric acid with a concentration of 85%, slowly add 28ml of water, and stir evenly.
[0049] 3: Slowly add the diluted phosphoric acid to the calcium hydroxide emulsion while stirring. After the dropwise addition, the stirring reaction was continued at normal temperature for 2 hours to stop, and the calcium phosphate intermediate emulsion was obtained.
[0050] 4: Titanium oxysulfate (TiOSO 4 ) 3.2g into 100ml of water, dissolved for later use.
[0051] 5: Weigh 2.86g of calcium hydroxide, add 50ml of water and stir to form an emulsion for later use.
[0052] 6: Add the titanyl sulfate solution prepared in step 4 to the calcium phosphate intermediate emulsion prepared in step 3, mix evenly and then drop into the calcium hydroxi...
Embodiment 3
[0055] The preparation method of antirust pigment of the present invention:
[0056] 1: Weigh 16.8g of calcium oxide [CaO], slowly add 200ml of water, stir well until the emulsification is uniform.
[0057] 2: Measure 14ml of concentrated phosphoric acid with a concentration of 85%, slowly add 28ml of water, and stir evenly.
[0058] 3: Slowly add the diluted phosphoric acid to the calcium hydroxide emulsion while stirring. After the dropwise addition, the stirring reaction was continued at normal temperature for 2 hours to stop, and the calcium phosphate intermediate emulsion was obtained.
[0059] 4: Titanium oxysulfate (TiOSO 4 ) 3.2g into 100ml of water, dissolved for later use.
[0060] 5: Weigh 2.86g of calcium hydroxide, add 50ml of water and stir to form an emulsion for later use.
[0061] 6: Add the titanyl sulfate solution prepared in step 4 to the calcium phosphate intermediate emulsion prepared in step 3, mix evenly and then drop into the calcium hydroxide emul...
