The invention discloses a CaCO3 surface treatment method for a high-filling PBAT biodegradable film and a preparation method of the film. The invention belongs to the technical field of high polymer materials. The high-filling PBAT biodegradable film is prepared from the following raw materials: 50 to 90 percent of PBAT, 10 to 50 percent of CaCO3, 0 to 3 percent of a surfactant, 0 to 1 percent ofa dispersing agent, 0 to 1 percent of a chain extender, 0 to 1 percent of a lubricating agent and 0 to 1 percent of an antioxidant. CaCO3 is modified through a surfactant and then mixed with PBAT andother auxiliaries, twin-screw granulation is conducted, and then film blowing is conducted through a film blowing machine. The surfactant organic silicon material reacts with a trace amount of water on the surface of CaCO3 to be hydrolyzed so that a Si-X bond forms a Si-OH bond, and the Si-OH bond and -OH on the CaCO3 surface undergo polycondensation dehydration to form a monomolecular film, thereby promoting the hydrophilicity of the modified CaCO3 surface to be changed into hydrophobicity, effectively enhancing the compatibility between CaCO3 and PBAT, and ensuring that the activation degreeof the modified CaCO3 is up to 90% or above.
