Abstract
Disclosed herein are oxygen generating compositions. More specifically, the oxygen generating compositions comprise potassium superoxide or sodium peroxide, a material for stabilizing the reactivity and oxidizing power of potassium superoxide or sodium peroxide, and optionally at least one selected from an oxidation catalyst of carbon monoxide, a material for improving the moldability and processability of the composition and a material for increasing initial carbon dioxide absorption rate. The oxygen generating compositions can be utilized in a wide range of applications.
The material for stabilizing the reactivity and oxidizing power of potassium superoxide or sodium peroxide is selected from calcium hydroxide (Ca(OH)2), aluminum hydroxide (Al(OH)3), magnesium hydroxide (Mg(OH)2), barium hydroxide (Ba(OH)2), calcium carbonate (CaCO3), talc and clay. The oxidation catalyst of carbon monoxide is selected from copper oxide (CuO), manganese oxide (MnO) and a mixture thereof (hopcalite). The material for improving the moldability and processability of the oxygen generating compositions is selected from glass powder, glass fiber, ceramic fiber, steel wool, bentonite, kaolinite, sodium silicate and potassium silicate. Since the oxygen generating compositions have stabilized reactivity and oxidizing power, they can be used in household goods. In addition, since the oxygen generating compositions have a higher compressive strength than pure potassium superoxide or sodium peroxide, they can be processed into various shapes.
