| titleOfInvention | Preparation method of mesoporous silica water-based ceramic slurry |
| abstract | The invention relates to the technical field of lithium ion battery coating diaphragms, and discloses a preparation method of mesoporous silica aqueous ceramic slurry, which comprises the following steps: A. placing mesoporous silica nano particles under an acidic condition, chemically modifying the mesoporous silica nano particles by using a silane coupling agent to prepare an ethylene mesoporous inorganic particle intermediate, and reserving the intermediate for later use; B. and B, adding the vinylated mesoporous inorganic particle intermediate prepared in the step A into a mixed system consisting of active monomers of isooctyl acrylate, methyl methacrylate, acrylonitrile, 2-ethyl hexyl acrylate, acrylamide, an emulsifier and an initiator, polymerizing by an emulsion polymerization method to prepare a water-based block copolymer, and obtaining the mesoporous silicon oxide water-based ceramic slurry. The invention solves the problem of poor heat resistance of the existing battery diaphragm. |
