Zusammenfassung:	The invention relates to a stripped or stripped modified boron nitride nanosheet, a preparation method thereof and application of the stripped or stripped modified boron nitride nanosheet in enhancing a polyurea composite material, and the stripped modified boron nitride nanosheet has the thickness of 2.31 +/-0.14 nm and the surface amino grafting rate of 3-5%. The stripped boron nitride nanosheet (B-BN) is prepared by solvent-free high-efficiency stripping by utilizing mechanical and chemical energy, and the stripped modified boron nitride nanosheet (M-BN) is prepared by performing ball milling modification on the stripped boron nitride nanosheet (B-BN) by adopting m-xylylenediamine (MXDA). The stripped boron nitride nanosheet has a larger specific surface area, so that the dispersity in a polyurea matrix is improved; besides a large specific surface area, the stripped and modified boron nitride nanosheet also contains amino groups on the surface, and can be linked with an isocyanate component through covale
