Embodiment 1
[0040] The preparation method of modified expanded vermiculite A includes the following steps: (1) Carry out incomplete expansion and calcination of vermiculite: take vermiculite raw material for impurity removal, and put it into a rotary furnace at a temperature of 850 ° C, heat and expand for 13 seconds, and the output Incomplete expanded vermiculite is obtained after feeding, and its density is that the bulk density is 1050kg / m 3 ;
[0041] (2) Add the incompletely expanded vermiculite to the solvent, fully stir and ultrasonically disperse for 30 minutes to obtain a vermiculite suspension, the solvent is butanol, and add the suspension and the carbon-forming catalyst ammonium polyphosphate into a closed reaction vessel , heated to 150°C, stirred at high speed and kept warm for 3 hours to obtain a suspension;
[0042] (3) Add a fire-resistant modifier to the vermiculite suspension, and carry out ultrasonic dispersion for 50 minutes; wherein, the fire-resistant modifier is c...
Embodiment 2
[0045] On the basis of Example 1, change the vermiculite heating expansion time and temperature, so that the bulk density of the expanded vermiculite obtained in step (1) is 850kg / m 3 , the other preparation steps are the same to obtain modified expanded vermiculite B
Embodiment 3
[0047] On the basis of Example 1, change the heating and expansion time and temperature of the vermiculite, so that the bulk density of the expanded vermiculite obtained in step (1) is 2000kg / m 3 , the other preparation steps are the same to obtain modified expanded vermiculite C.
