Embodiment 1
[0025] Stir 50 parts of heavy calcium carbonate at 75°C, add 1 part of aluminate coupling agent, continue stirring for 30-60 minutes, and obtain aluminate modified heavy calcium carbonate after cooling.
Embodiment 2
[0027] Stir 75 parts of heavy calcium carbonate at 85°C, add 1 part of aluminate coupling agent, continue stirring for 30-60 minutes, and obtain aluminate modified heavy calcium carbonate after cooling.
Embodiment 3
[0029] Stir 100 parts of heavy calcium carbonate at 80°C, add 1 part of aluminate coupling agent, continue stirring for 30-60 minutes, and obtain aluminate modified heavy calcium carbonate after cooling.
[0030] 2. Determination of activation rate
[0031] Take by weighing 5g of the aluminate-modified heavy calcium carbonate described in Example 1-3, its mass is recorded as m, put in a 250mL separating funnel, add 200mL of water, shake for 5min, then place on the funnel stand, Stand still for 30 minutes, after the obvious stratification, put the sinking calcium carbonate into the crucible filter which has been dried to constant weight at one time, remove the water by suction filtration, move into the constant temperature box, and dry to constant weight. The activation rate is represented by mass percentage, denoted as AD, and the specific calculation is: AD=(1-(m2-m1) / m)×100%, wherein: m2 is the mass (g) of the crucible and uncoated calcium carbonate after drying ; m1 is the...
