Modified calcium carbonate having good processability and preparation method thereof

The invention discloses modified calcium carbonate having good processability and a preparation method thereof. The modified calcium carbonate is characterized by being prepared from, by weight, 100-150 parts of calcium carbonate, 30-50 parts of sodium oleate, 0.3-0.7 part of sodium dodecyl benzene sulfonate, 1-3 parts of sodium bicarbonate, 4-8 parts of styrene, 0.02-0.05 part of potassium persulfate, 3-5 parts of gas-phase silica, 2-3 parts of organic bentonite, 2-3 parts of quartz powder, 1-3 parts of glycerol monostearate, 2-3 parts of straw fiber powder and anappropriate amount of deionized water. The added quartz powder, the added glycerol monostearate and the added straw fiber powder improve the advantages of dispersibility, antistatic property, abrasion resistance, fire resistance, high mechanical strength, good adsorbability and the like of the calcium carbonate, the calcium carbonate can have good compatibility with lots of substances, produces stronger bonding power, serves as a packing to be added and does not reduce the performance of a product, the cost can be reduced, and the modified calcium carbonate is high in large-scale production feasibility and worthy of popularization.
