Slow-release type solid chlorine dioxide generating agent and preparation method thereof

Abstract

The invention discloses a slow-release type solid chlorine dioxide generating agent and a preparation method thereof. The slow-release type solid chlorine dioxide generating agent has the advantages of plain and thin smell, stable concentration character, long lasting period and convenience in use. The slow-release type solid chlorine dioxide generating agent is prepared from the following components in parts by mass: 15 to 25 parts of sodium chlorite, 10 to 20 parts of urea nitrate, 40 to 50 parts of medical stone, 4 to 8 parts of magnesium sulfate, 4 to 8 parts of calcium sulfate, 3 to 8 parts of super absorbent resin and 2 to 6 parts of beta-cyclodextrin. The preparation method comprises the steps of smashing the medical stone into small particles and activating for 60 to 120 minutes at 90 to 100 DEG C to open inner holes of the medical stone; with the activated medical stone as a carrier, adding magnesium sulfate and calcium sulfate; adding sodium chlorite and urea nitrate; drying under assistance of the super absorbent resin; adding beta-cyclodextrin and curing into particle shapes; utilizing antioxidant aluminum plastic package bags to seal and package the cured particle-shaped products. The slow-release type solid chlorine dioxide generating agent can be widely applied to the field of space environment purification.

Description

Technical field [0001] The invention relates to a slow-release solid chlorine dioxide generator. In addition, the invention also relates to a method for preparing a slow-release solid chlorine dioxide generator. Background technique [0002] Everyone has the right to health. Health is very important to a family. With the development of society and the improvement of people's living standards, people pay more and more attention to the problem of indoor and car air pollution. Harmful gases indoors and cars mainly include formaldehyde, benzene, toluene, xylene, TVOC, bacteria, viruses, etc. Indoors and cars are the main places of people's lives. It is well known that inhaling too much formaldehyde can cause pregnant women's malformations, leukemia and other diseases. Therefore, indoor and car air purification, sterilization and disinfection are urgent. [0003] Chlorine dioxide disinfectant is the only high-efficiency disinfectant among the internationally recognized chlorine-contai...
