The invention relates to a method for polymerizing acrylate organic silicon on a titanium dioxide surface. The method is characterized by comprising the following steps: carrying out surface modification on TiO2 by using a cationic monomer, carrying out pre-emulsification on a monomer mixture composed of 15 parts of methyl methacrylate, 15 parts of butyl acrylate, 10 parts of vinyltriethoxysilane and 5 parts of alpha-methacrylic acid with 80 parts of water, 1 part of initiator ammonium persulfate and 2 parts of emulsifier to obtain a pre-emulsified mixed monomer emulsion; and heating the TiO2 slurry to 80 DEG C, adding 0.3 part of initiator ammonium persulfate, initiating the reaction for 5 minutes, slowly adding the pre-emulsified mixed monomer emulsion into the TiO2 slurry within 2-5 hours, and keeping the temperature at DEG C to carry out thermostatic reaction for 1 hour, thereby obtaining the polyacrylate-organic-silicon-coated TiO2 slurry. |
