Flaky mortar and preparation method thereof

The invention provides flaky mortar and a preparation method thereof, and the preparation method comprises the following steps: step S100, obtaining a wet mixture, and granulating the wet mixture to obtain wet particles; step S200, drying the wet granules to obtain semi-dry granules; and step S300, tabletting the semi-dry particles to obtain the flaky mortar. According to the preparation method, wet mixed materials are granulated, dried and then tableted, so that the solvent content in semi-dry particles is effectively reduced, proper compressibility and physical properties of the semi-dry particles are kept, the semi-dry particles are uniformly distributed in the tableting process, and the porosity in a formed tablet body is effectively improved, so that the content of the semi-dry particles is reduced in the transportation and transfer process, and the content of the semi-dry particles in the tablet body is reduced. The mechanical strength of the flaky mortar is guaranteed, meanwhile, when the flaky mortar
