Embodiment 1
[0030] In parts by weight, weigh 40 parts of heavy calcium carbonate, 4 parts of stearic acid, and 240 parts of tap water. Place the heavy calcium carbonate in a grinder and grind it at room temperature at 160r / min for 1 hour to obtain an average particle size. For heavy calcium carbonate powder with a diameter of 0.2mm, add heavy calcium carbonate powder to tap water and stir at 200r / min for 20 minutes at room temperature to obtain a heavy calcium carbonate suspension. Slowly add stearic acid to the heavy calcium carbonate suspension Add the mixture for 10 minutes, place it in a water bath at 70°C and stir at 250r / min for 2 hours to obtain a mixed solution of heavy calcium carbonate. Place the mixed solution of heavy calcium carbonate in a vacuum pump and filter for 30 minutes at room temperature. The filter cake was dried in an oven at 100°C for 1 hour, cooled at room temperature, and ground to obtain activated heavy calcium carbonate powder;
[0031] Then, in parts by weight, ...
Embodiment 2
[0034] In parts by weight, weigh 45 parts of heavy calcium carbonate, 4.5 parts of stearic acid, and 270 parts of tap water. Place the heavy calcium carbonate in a grinder and grind for 1.5 hours at 170r / min at room temperature to get an average Heavy calcium carbonate powder with a particle size of 0.3mm, add the heavy calcium carbonate powder to tap water, stir at 220r / min for 25min at room temperature to obtain a heavy calcium carbonate suspension, slowly add stearic acid to the heavy calcium carbonate suspension Into the solution, add for 12.5min, place in a water bath at 75℃, stir at 275r / min for 3h to obtain a mixed solution of heavy calcium carbonate. Place the mixed solution of heavy calcium carbonate in a vacuum pump and filter for 35min at room temperature. , Take the filter cake, dry it in an oven at 105°C for 1.5 hours, cool at room temperature, and grind to obtain activated heavy calcium carbonate powder;
[0035] Then, in parts by weight, weigh 70 parts of polypropy...
Embodiment 3
[0038] In parts by weight, weigh 50 parts of heavy calcium carbonate, 5 parts of stearic acid, and 300 parts of tap water. Place the heavy calcium carbonate in a grinder and grind at 180r / min for 2h at room temperature to obtain an average particle size. For heavy calcium carbonate powder with a diameter of 0.4mm, add heavy calcium carbonate powder to tap water and stir at 240r / min for 30 minutes at room temperature to obtain a heavy calcium carbonate suspension. Slowly add stearic acid to the heavy calcium carbonate suspension Add the mixture for 15 minutes, place it in a water bath at 70~80℃, and stir at 300r / min for 4 hours to obtain a mixed solution of heavy calcium carbonate. Place the mixed solution of heavy calcium carbonate in a vacuum pump and filter for 40 minutes at room temperature. , Take the filter cake, dry it in an oven at 110°C for 2h, cool it at room temperature, and grind it to obtain activated heavy calcium carbonate powder;
