Example Embodiment
[0046] Example 1-1
[0047] First modify the aluminum hydroxide and calcium carbonate, and use dynamic (fluidized bed) heating method to increase the temperature of aluminum hydroxide and calcium carbonate to 80℃-130℃. 20 parts by weight of aluminum hydroxide over 200 mesh and 50 parts by weight of calcium carbonate over 500 mesh. 30 (weight) parts of polysiloxane modifier vinyl trichlorosilane are atomized into aluminum hydroxide and calcium carbonate to maintain Between 80-130°C, continue to boil in a fluidized bed for 2-6 minutes to obtain surface-modified aluminum hydroxide powder and calcium carbonate powder.
Example Embodiment
[0048] Example 1-2
[0049] In the dynamic (fluidized bed) heating method, when the temperature of aluminum hydroxide is 80℃-130℃, under its high-speed dynamic condition, according to 70 parts (weight) of aluminum hydroxide, 30 (weight) A part of polysiloxane modifier 3-(methacryloxy)propyltrimethoxysilane was added to 200 mesh aluminum hydroxide by atomization method, kept at 80-130℃, and continued to fluidize The bed is boiling, and the holding time is 2-6 minutes to obtain surface-modified aluminum hydroxide powder.
Example Embodiment
[0050] Example 1-3
[0051] In the dynamic (fluidized bed) heating method, when the temperature of calcium carbonate is 80℃-130℃, under its high-speed dynamic condition, according to 70 parts (weight) calcium carbonate, 30 (weight) parts are polymerized The siloxane modifier 3-aminopropyltrimethoxysilane was added to 200 mesh aluminum hydroxide by atomization method, kept at 80-130℃, and continued to boil in the fluidized bed for 2-6 minutes , To obtain surface modified calcium carbonate powder.
