[0040] The present invention also provides a preparation method of ceramic fiber porous filter material reinforcing agent, comprising the following steps:
[0041] A) adding 2 to 8 parts by weight of surfactant into 100 parts by weight of deionized water, and then adding 5 to 40 parts by weight of active mineral powder to obtain a mixed solution;
[0042] B) dispersing the mixed solution by ball milling to obtain a mixed slurry;
[0043] C) adding 20-80 parts by weight of inorganic adhesive material into the mixed slurry, stirring and mixing to obtain a ceramic fiber porous filter material reinforcement.
[0044] In the present invention, the kind and consumption of described tensio-active agent, deionized water, active mineral powder and inorganic sticky material are the same as the kind of above-mentioned surfactant, deionized water, active mineral powder and inorganic sticky material It is consistent with the dosage and will not be repeated here.

Embodiment 1
[0064] Add 2 parts by weight of polyethylene glycol to 100 parts by weight of deionized water, then add 2 parts by weight of kaolin, 1 part by weight of bentonite and 5 parts by weight of nano silicon dioxide, and use a planetary ball mill to grind and disperse; then, Transfer the ground slurry to an overhead stirrer, add 10 parts by weight of aluminum sol, 8 parts by weight of silica sol and 2 parts by weight of aluminum dihydrogen phosphate, stir and mix at a high speed to obtain a ceramic fiber porous filter material reinforcement . The obtained reinforcing agent has a solid content of 10.43% and a viscosity of 5 mPa·s at room temperature. After strengthening treatment, the ultimate strength of the radially compressed C-ring sample of the ceramic fiber filter tube is 0.97MPa, and the pressure difference is 400Pa.
Embodiment 2
[0066] Add 5 parts by weight of polyethylene glycol to 100 parts by weight of deionized water, then add 2 parts by weight of kaolin, 1 part by weight of bentonite and 7 parts by weight of nano silicon dioxide, and use a planetary ball mill to grind and disperse; then, Transfer the ground slurry to an overhead stirrer, add 8 parts by weight of aluminum sol, 8 parts by weight of silica sol and 4 parts by weight of aluminum dihydrogen phosphate, stir and mix at a high speed to obtain a ceramic fiber porous filter material reinforcement . The obtained reinforcing agent has a solid content of 11.20% and a viscosity of 6 mPa·s at room temperature. After strengthening treatment, the ultimate strength of the radially compressed C-ring sample of the ceramic fiber filter tube is 1.15MPa, and the pressure difference is 420Pa.
