The present invention provides a kind of preparation method of organic polymer composite Nano zirconium oxide hard shell and its application of the preparation method manufacture phone housing using the organic polymer composite Nano zirconium oxide hard shell.The preparation method is to be injection molded into outer sleeve blank with after the tetragonal phase zirconium oxide nano powder mixing of organic matter macromolecule and surface modifying agent, make its zirconia surface that martensitic traoformation occur under ultrasonic cavitation effect outer sleeve blank, tetragonal phase zirconium oxide is changed into monocline phase zircite, zirconia grains volume expansion, compression is generated to inside, the intensity of outer casing member is improved, and surface ceramic component accounting increases, surface hardness increases.The technical solution solves sintering ceramic shell, lays particular stress on, at high cost, the disagreeableness problem of degreasing sintered energy consumption environment；Solve that organic polymer shell is not wear-resisting, the bad problem of surface hardness. |
