Embodiment 1
[0017] Embodiment 1: in parts by mass, 100 parts of nanometer calcium carbonate (5~40 nanometers) and 20 parts by mass percentage composition are the organosilicon quaternary ammonium salt methanol solution of 50%, and its molecular formula is (CH 3 O) 3 Si(CH 2 ) 3 N + (CH 3 )(C 10 h 21 ) 2 Cl - , ultrasonically dispersed for 30 minutes, and reacted at 100±5°C for 48 hours. After the reaction, the product was repeatedly washed with deionized water and methanol, and then dried for 24 hours to obtain nanocarbonic acid grafted on the surface with good flexibility and long chains. Calcium salts. In parts by mass, add 20 parts of sulfonate to 100 parts of the obtained inorganic nanoparticle organic ion salt, the molecular formula is R-(OCH 2 CH 2 ) m -O(CH 2 ) 3 SO 3 - K + (R=C 1 -C 15 , m=1~60), reacted at 100±5°C for 48 hours, collected the product and extracted it with toluene. Separation, and finally vacuum drying to obtain gel-like nanometer calcium carbona...
Embodiment 2
[0018] Embodiment 2: by mass parts, with 100 parts of nano-silica (5~20 nanometers) and 100 parts of mass percentage composition be the organosilicon quaternary ammonium salt methanol solution of 30%, its molecular formula is (CH 3 O) 3 Si(CH 2 ) 6 N + (CH 3 )(C 10 h 21 ) 2 Cl - , put it into a three-necked flask, ultrasonically disperse for 20 minutes, and react at 20±2°C for 60 hours. After the reaction, the product is repeatedly washed with deionized water and methanol, and then dried for 24 hours to obtain good flexibility of surface grafting. Long chain nano silica salt. In parts by mass, add 100 parts of sulfonate to 100 parts of the obtained nano silicon dioxide salt, molecular formula is C 9 h 19 -(OCH2 CH 2 ) 6～9 -O(CH 2 ) 3 SO 3 - K + , reacted at 30±5°C for 60 hours; collected the product and extracted it with toluene, repeated several times, then the raffinate phase was rotary evaporated at 95±5°C, dispersed the residue in acetone, centrifuged, and...
Embodiment 3
[0019] Embodiment 3: by mass parts, with 100 parts of nano-titanium dioxide (10~30 nanometers) and 50 parts of mass percent compositions be the organosilicon quaternary ammonium salt methanol solution of 50%, and its molecular formula is (CH 3 O) 3 Si(CH 2 ) 8 N + (CH 3 )(C 10 h 21 ) 2 Cl - , put it into a three-necked flask, ultrasonically disperse for 50 minutes, and react at 120±5°C for 50 hours. After the reaction, the product is washed repeatedly with deionized water and methanol, and then dried for 24 hours to obtain good flexibility of surface grafting. Long chain nano titanium dioxide salt. In parts by mass, add 50 parts of sulfonate in 100 parts of the obtained nano-titanium dioxide salt, its molecular formula is C 9 h 18 -(OCH 2 CH 2 ) 10 -O(CH 2 ) 3 SO 3 - K + , react at 20±5°C for 48 hours. The collected product was extracted with toluene, and after repeated several times, the raffinate phase was rotatably evaporated at 70±5°C, the residue was di...
