Abstract

The invention relates to the technical field of preparation of environment-friendly materials, and particularly discloses a material with a negative ion releasing effect and a preparation method thereof. The preparation method of the material with the negative ion releasing effect comprises the following steps: preparation of iron disulfide-silver chloride dispersion liquid: dispersing iron disulfide and silver chloride in water to form the iron disulfide-silver chloride dispersion liquid; preparation of a negative ion powder compound dispersion liquid: dispersing a negative ion powder compound in water to form a negative ion powder compound dispersion liquid; and preparation of the material: uniformly mixing the iron disulfide-silver chloride dispersion liquid and the negative ion powder compound dispersion liquid, adding a sodium borohydride solution under a stirring condition, continuing stirring for 30-60 minutes after the sodium borohydride solution is completely added, conducting standing for 1-3 hours, and separating a solid product to obtain the material with the negative ion releasing effect. Experimental results show that the material with the negative ion releasing effect prepared by the method has very excellent negative ion releasing capability.

Description

technical field [0001] The invention relates to the technical field of preparation of environment-friendly materials, in particular to a material capable of releasing negative ions and a preparation method thereof. Background technique [0002] Negative ions specifically refer to air negative (oxygen) ions; in fact, the general term for negatively charged single gas molecules and hydrogen ion clusters; among them, forests and wetlands are important places for generating air negative (oxygen) ions. With the improvement of people's living standards, the air requirements in closed environments such as indoors are also gradually increased; wherein, negative ions in the air are one of the important indicators for measuring air quality. [0003] Tourmaline, the general name of tourmaline minerals, due to its unique properties such as piezoelectricity, pyroelectricity, conductivity, far-infrared radiation, and release of negative ions; currently tourmaline is often compounded with ...
