application number: 201610334699.4 Application date: 2016-05-19
Abstract: provide a direct use for electrostectrecturic powder spraying with pearlescent pigment and its preparation method. The pearlescing pigment of the invention includes a pearly pigment made from flaky natural mica, flaky synthetic mica, flaky alumina, flaky silicon oxide, flaky glass scales and other flaky substrates as a substrate, and a layer of doped semiconductor oxide layer on the surface bread cover of the pearlescing pigment base, the doped semiconductor oxide layer is selected from tin, zinc and radon as the main component. At least one and doped oxides selected from palladium, aluminum and tin are made of at least one doped oxide, in which the metal as the main component and the doped metal cannot be tin at the same time, which not only ensures the matching problem with the conductivity of the resin in the powder coating, but also ensures the brightness and color of the powder spray, and also reduces the binding step of the pearlescent pigment in the powder coating, improves the utilization rate of the pearlescent pigment and simplifies the process.
