Embodiment Construction
[0011] A preparation method for highly dispersive modified calcium carbonate for color masterbatch,
[0012] First weigh heavy calcium carbonate 100, diffusing agent NNO 0.3, ferrocene 0.2, bisphenol A polycarbonate 0.3, rutile titanium dioxide 1, talcum powder 0.5, white oil 0.1, methyl phenyl Silicone oil ethylene bisoleic acid amide 0.6, high-density linear polyethylene 1, stearic acid 0.3, paraffin wax 1, isopropyl tris(dioctyl pyrophosphate acyloxy) titanate 3, prepared according to the following steps:
[0013] First, dry the heavy calcium carbonate at 90-100°C until the water content is less than 0.5%, and then add it to the high-speed mixer; mix the diffusing agent NNO, ferrocene, bisphenol A polycarbonate, rutile titanium dioxide, Add talcum powder and white oil into a high-speed mixer, and stir at a speed of 800-1000 rpm for 3-5 minutes at 80-95°C; Linear polyethylene, stearic acid, paraffin, isopropyl tris (dioctyl pyrophosphate acyloxy) titanate are added to the h...
