[0030] Example 1: Organic composite porous ceramic material A1
[0031] The preparation method of the organic composite porous ceramic material A1 includes the following steps:
[0032] (1) Modified cellulose: Dissolve the silane coupling agent in the solvent, then add an appropriate amount of acetic acid, adjust the PH value to 4, soak the vegetable cellulose in this solution at 60-80°C for 9-12h, and take it out. Filtered, dried, and ball milled to obtain modified cellulose with a particle size of 2 μm. The mass ratio of plant cellulose to silane coupling agent is 5:1.
[0033] (2) Mix 10g of silicon dioxide, 5g of aluminum powder, 70g of diatomaceous earth, and 15g of modified cellulose into a mixed powder, then add 3g of hydroxymethyl cellulose and 120g of water to the mixed powder and mix evenly. After reacting at 60-80°C for 4-6 hours and freeze-drying, a porous ceramic precursor is obtained. Among them, the average particle size of silica and aluminum powder is 5-8 μm, and ...
