Refreshing and negative oxygen ion releasing vehicle-mounted healthy incense and preparation method thereof

The invention discloses a refreshing and negative oxygen ion releasing vehicle-mounted healthy incense and a preparation method thereof.The preparation method includes the steps that kapur, camphor, storax, poria cocos, rhizoma acori graminei, peppermint essential oil, water, elm bark powder and bentonite are subjected to ball milling and mixing and then subjected to compression molding, a primary incense product is obtained, then the surface of the primary incense product is wrapped with a layer of composite active material prepared by mixing ZnO and NaFe3Al6 (BO3) 3 (Si6O18) (OH) 4 and Sr0. 06Mn0. 01Zr0. 965P2O7-TiO2, and the negative oxygen ion releasing vehicle-mounted healthy incense is obtained. And carrying out secondary compression molding and natural air-drying to obtain the product. Tests show that the release amount of negative oxygen ions of the obtained vehicle-mounted health incense product can reach 2.3 * 10 < 9 >/m < 3 >, especially under sunlight illumination, the concentration of the generat
