description The invention discloses a preparation method of high-whiteness and acid-resistant core-shell structure calcium carbonate, which comprises the following steps: dispersing calcium carbonate powder in water, adding silicate, stirring and mixing, heating to 80-90 DEG C, dropwise adding inorganic acid to adjust the pH value of the solution, and reacting to obtain CaCO3 coated SiO2 slurry; washing and drying are carried out, such that CaCO3 coated SiO2 composite powder is obtained; dispersing the CaCO3 coated SiO2 composite powder in an alcohol A solution, adding deionized water, heating, adding an alcohol B solution containing a titanium source, and reacting to obtain hydrated TiO2 coated CaCO3 coated SiO2 slurry; washing and drying are carried out, such that hydrated TiO2 coated CaCO3 coated SiO2 composite powder is obtained; and calcining the hydrated TiO2 coated CaCO3 (at) SiO2 composite powder, so as to obtain the CaCO3 (at) SiO2 (at) TiO2 composite powder. The calcium carbonate product with the CaCO3 (at) SiO
