Abstract

The invention relates to high anion tourmaline powder and a preparation method thereof. The high anion tourmaline powder is prepared from the following compositions by weight percentage: 60 to 80 percent of tourmaline, 5 to 10 percent of cerium oxide, 2 to 5 percent of yttrium oxide, 5 to 10 percent of neodymium oxide and 5 to 15 percent of titania, wherein the D50 of the high anion tourmaline powder is less than or equal to 2 micrometers. Compared with the prior art, the high anion tourmaline powder can obviously improve the anion-generating capacity, is safe and reliable, contributes to adjust the physiological function of human body, eliminate fatigue and improve cardiovascular and cerebrovascular disease symptoms and the immunity of the human body, has obvious health-care effect, can be widely used in building materials such as a coating, an emulsion paint, lacquer putty, ceiling and a furniture coating, and can also be used in the fields of plastic, fiber and so on. Simultaneously, the method for preparing the high anion tourmaline powder has simple technique and low cost, and prepared products have stable performance.
