Abstract

The invention discloses a compound oxygen generating agent and a preparation method thereof. The compound oxygen generating agent comprises 80-85% of sodium percarbonate, 15-20% of potassium superoxide and 0.1-0.2% of manganese dioxide. The preparation method comprises the steps of pulverizing sodium percarbonate to 80-120 mesh powder with a pulverizer, oven-drying potassium superoxide and manganese dioxide, proportionally mixing, feeding the mixed materials into a rotary tablet machine, and making into tablets. Compared with the simple sodium percarbonate oxygen generating agent, the inventive compound oxygen generating agent improves oxygen generation speed and prolongs service life by 10-15% under the same quantity, and has the advantages of simple preparation method and convenient service.

Description

Composite oxygen generator and preparation method Technical field The invention relates to the field of chemical oxygen generation, in particular to an oxygen generation agent based on sodium percarbonate and potassium superoxide and a preparation method. Background technique The application date is 1998.10.26, and the application number is 98120578.X. An oxygen generator for human oxygen supply is disclosed. Its components include potassium superoxide and sodium bicarbonate, and its formula is 1:1.1-1:1.2; Bunsen Oxygen can be made into tablets with small volume. Therefore, it is very convenient to use and will not cause pollution; the application date is 2004.7.19, and the mixed type oxygen generating agent of the chemical oxygen self-rescuer with the application number 200410054746.7 is disclosed. The present invention relates to a mixed type chemical oxygen self-rescuer. Oxygen-generating agents are composed of potassium superoxide oxygen-generating agents in the form...
