Abstract

The invention discloses modified anion spherical powder and a preparation method thereof. The powder comprises the following components in parts by weight: 80-120 parts of tourmaline powder, 12-24 parts of a composite modifier and 35-45 parts of a filling aid, wherein the composite modifier comprises an organic modifier and an inorganic modifier; and the ratio of the organic modifier to the inorganic modifier is 2:1. The preparation method comprises the following steps: preparing raw materials, modifying the tourmaline powder, and performing drying. By adopting the modified anion spherical powder and the preparation method thereof, spherical modified anion powder can be prepared, and the spherical modified anion powder has good dispersibility and stability in a macromolecule material, andin addition is high in anion induction amount and good in smell purification and formaldehyde removal effect.

Description

technical field [0001] The invention relates to the technical field of environmental protection chemical industry, in particular to a modified negative ion spherical powder and a preparation method thereof. Background technique [0002] Negative air ions are also called negative oxygen ions or negative ions. They are a kind of ions or ion clusters with floating points in the atmosphere. They have the functions of purifying air, anti-oxidation, anti-aging, and removing free radicals in the body. "Air vitamins" have become one of the important indicators to measure the quality of air. In nature, through the influence of ultraviolet rays, lightning, cosmic rays or radiation, the atmosphere is ionized to produce negative ions, so nature itself has the ability to produce negative ions. Among them, tourmaline, opal, six-ring stone, and strange ice stone have the function of releasing negative ions, and have been widely studied by people. In particular, tourmaline, because of its...
