The organic matter coating synthetic mica powder body, the production method and the make-up charge which uses that

摘要

As for this invention, the organic matter carpet course by the organic coupling agent on the synthetic mica powder body surface connects to firm chemically, the use impression and the organic matter coating synthetic mica powder body which is superior in water repellency characteristic, furthermore, when the organic silicone which possesses the Si H basis it uses, as the organic coupling agent also the hydrogen occurrence with Si H basic remains almost offers the organic matter coating synthetic mica powder body which is not. The said organic matter coating synthetic mica powder body after making with the synthetic mica powder body and the ammonium ion contact at underwater, removes the liquid phase with liquid separation hard, dries the solid phase below the 200 and after making the organic coupling agent the head-end process and the surface volatile it can point NH_{3 of the} synthetic mica powder body come in contact which is prepared, bakes and it processes, it can obtain the coating process which forms organic matter carpet course on the synthetic mica powder body surface and, with the production method of having.
