Abstract

The embodiment of the invention discloses a preparation method of modified tourmaline powder, which belongs to the technical field of tourmaline fine deep processing. The preparation method of the modified tourmaline powder comprises three steps of material preparation, transition metal element doping modification in crystal lattice, and chitosan external surface embedding modification. The prepared modified tourmaline powder can significantly improve pyroelectricity and mid-frequency infrared (MWIR) radiation performance, presents obvious biological efficacy, and has higher application value for human health.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of fine deep processing of tourmaline, in particular to a preparation method of modified tourmaline powder. Background technique [0002] Tourmaline, the general term for tourmaline minerals, is a ring silicate crystal mineral composed of elements such as Al, Na, Ca, Mg, B and Fe, containing water and fluorine. In the 1980s, Japanese scholar Kubo discovered for the first time that there were permanent spontaneous electrodes in tourmaline, which aroused people's great attention to tourmaline. Tourmaline has unique functions such as piezoelectricity and pyroelectricity, and can release far-infrared rays and negative ions. At the same time, it exhibits weak bioluminescence and bioelectricity effects on living organisms. [0003] Experimental research has revealed: (1) The spontaneous polarization and pyroelectric properties of tourmaline can make the crystal spontaneously generate wea...
