TITANIUM SOL CARBON SEQUESTRATION ADDITIVE AND PREPARATION METHOD AND USE THEREOF, AND METHOD FOR CARBON SEQUESTRATION OF CEMENT-BASED MATERIAL
Provided are a titanium sol carbon sequestration additive and a preparation method and use thereof, and a method for carbon sequestration of a cement-based material. The method for preparing the titanium sol carbon sequestration additive includes: mixing titanium tetraisopropanolate with an ammonia aqueous solution to obtain a first mixture, subjecting the first mixture to hydrolysis to obtain a hydrolysis solution, and drying the hydrolysis solution to obtain a titanium dioxide powder; mixing the titanium dioxide powder with sodium polyacrylate and a methyldiethanolamine (MDEA) aqueous solution to obtain a second mixture, and subjecting the second mixture to amination to obtain a solution A; mixing water with ethanol to obtain a solution B; and mixing the solution A and the solution B with a catalyst to obtain a mixed solution, and subjecting the mixed solution to solation to obtain the titanium sol carbon sequestration additive.
