[0025]The aluminum chloride powder and distilled water are mixed into the reaction kettle at a mass ratio of 1:10, the internal temperature of the reaction kettle is raised to 340 ° C, and the air pressure is raised to 2.6 MPa to prepare a reaction mixture, which is added to the reaction mixture at 30 mL / min. Ammonia gas was introduced at a rate of 100 °C for 30 minutes, and the filter residue was obtained by filtration. The filter residue was dried in an oven at a temperature of 105 ° C for 6 hours. After drying, it was ground through a 400-mesh sieve to obtain a sieved product; in parts by weight, Weigh 3 parts of the above-mentioned sieved material, 7 parts of 3-methacryloyloxypropyl trimethoxysilane and 15 parts of absolute ethanol and put them into the there-necked flask, put the there-necked flask into the ultrasonic oscillator, and the water bath temperature is Mix for 50 min under the conditions of 0 °C and ultrasonic frequency of 30 kHz, raise the temperature of the wa...

[0027] The aluminum chloride powder and distilled water were mixed into the reaction kettle at a mass ratio of 1:10, the temperature inside the reaction kettle was raised to 345 ° C, and the pressure was raised to 2.7 MPa to prepare a reaction mixture, which was added to the reaction mixture at 32 mL / min. Ammonia gas was introduced at a rate of 100 °C for 35 minutes, and the filter residue was obtained by filtration. The filter residue was dried in an oven at a temperature of 110 ° C for 7 hours. After drying, it was ground through a 400-mesh sieve to obtain a sieved product; Weigh 4 parts of the above-mentioned sieved material, 8 parts of 3-methacryloyloxypropyl trimethoxysilane and 17 parts of absolute ethanol and put them into the there-necked flask, put the there-necked flask into the ultrasonic oscillator, and the water bath temperature is Mix for 60 min at 2 °C and ultrasonic frequency of 32 kHz, raise the temperature of the water bath to 47 °C, and stir with a stirrer at...

[0029] The aluminum chloride powder and distilled water were mixed into the reaction kettle at a mass ratio of 1:10, the temperature inside the reaction kettle was raised to 350 ° C, and the pressure was raised to 2.8 MPa to prepare a reaction mixture, which was added to the reaction mixture at 35 mL / min. Ammonia gas was introduced at a rate of 100 °C for 40 minutes, and the filter residue was obtained by filtration. The filter residue was placed in an oven for drying at a temperature of 115 ° C for 8 hours. After drying, it was ground through a 400-mesh sieve to obtain a sieved product; Weigh 5 parts of the above-mentioned sieves, 9 parts of 3-methacryloyloxypropyl trimethoxysilane and 18 parts of absolute ethanol and put them into the there-necked flask, put the there-necked flask into the ultrasonic oscillator, and the temperature of the water bath is Mix for 70min at 5°C and ultrasonic frequency of 35kHz, raise the temperature of the water bath to 50°C, stir with a stirrer ...
