Problems solved by technology

But potassium permanganate solid is not easy to fix, and manganese dioxide and potassium manganate in the decomposition product can coat the surface of unreacted potassium permanganate in solid state simultaneously, thereby hindered the further processing of remaining potassium permanganate reaction, greatly reducing the reaction rate of the oxygen generator

Abstract

The invention provides a permanganate / montmorillonite nano composite material, belonging to the technical field of composite materials. The composite material is prepared by uniformly inserting permanganate into a montmorillonite lamella in a neutral or acidic environment so that the montmorillonite is tightly combined with the permanganate and uniformly dispersed in the permanganate on a nano scale. The permanganate / montmorillonite nano composite material has favorable stability and gas buffer performance, can be rapidly decompound to release oxygen under shielding or lighting conditions so as to be used as an oxygen storage material and used by various aerobic crowds, such as field workers, patients, and the like and various aerobic places such as hospitals, wards, offices, residences, shopping malls and the like.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a functional nanocomposite material with montmorillonite as a carrier, in particular to a potassium permanganate / montmorillonite nanocomposite material and its preparation; the invention also relates to the high Application of Potassium Manganate / Montmorillonite Nanocomposites as Oxygen Storage Materials. Background technique [0002] Oxygen storage materials are a class of materials that can reversibly absorb and release oxygen, and have the ability to absorb and release oxygen under specific conditions. Oxygen storage materials are mainly used in oxygen-demanding places such as hospitals, offices, residences, shopping malls and health care places, as well as oxygen-demanding people such as plateau transport vehicles, field workers, army barracks and soldiers. [0003] The research on oxygen production methods has made great progress, but so far, most of them adopt ph...
