| titleOfInvention | Multifunctional polyurea coating for power battery tray and preparation method and application thereof |
| abstract | The invention belongs to the technical field of pure electric vehicle coatings, and provides a multifunctional polyurea coating for a power battery tray, a preparation method and application thereof, wherein the adhesive force of the polyurea coating to a matrix is improved through modified isocyanate, so that the impact resistance of the coating is improved; by adding the modified carbon nanofiber, the modified nano cerium trifluoride and the modified nano lanthanum trifluoride, the shock resistance of the polyurea coating is improved, and the coating has super-hydrophobicity; by adding the graphene, the impact resistance of the coating is further improved; by adding the flame retardant, the coating has stable and efficient flame retardant performance. The results of the examples show that the multifunctional polyurea coating for the power battery tray provided by the invention has the tensile strength of 40MPa, the elongation at break of 450%, the tear strength of 121kN/m, the contact angle of 153 degrees, the UL-94 flame retardant test of V0 and the adhesion force with 45 steel of 16.57 MPa. |
