Oxygen production flux core for oxygen candles and preparation method thereof

The invention relates to an oxygen production flux core for oxygen candles and a preparation method thereof, and belongs to the technical field of chemical oxygen generation. The oxygen production flux core comprises the following raw material components in percentage by mass: 78-98% of an oxygen production source, 1-10% of a catalyst, 0.1-11% of a chlorine inhibitor and 0.2-5% of a binder. The oxygen production source is more than one of sodium chlorate and potassium perchlorate; the catalyst is more than one of cobaltosic oxide and cobaltic oxide; the chlorine inhibitor is more than one of magnesium oxide and sodium silicate; and the binder is kaolin. An oxygen production source is subjected to grinding and vibration screening pretreatment and then is subjected to dry mixing with other raw material components, and then water is added for wet mixing; and the mixed raw materials are pressed into an oxygen production flux core with the density of 1.9-2.1 g/cm , and the oxygen production flux core is obtained a
