[0002] Chlorine dioxide is chemically active and not very stable
At present, the reason for restricting the application and development of slow-release solid chlorine dioxide is to find a suitable carrier substance and slow-release material. This is because the activated chlorine dioxide has strong oxidative properties, and many conventional solidified carriers are used in this system. it is invalid

Embodiment 1
[0072] Embodiment 1: A slow-release solid chlorine dioxide preparation, the selected dosage form is block, made of the following raw materials (in terms of mass percentage):
[0073] Liquid chlorine dioxide 1%; sustained release agent 70%; glycerin 28%; essence 1%. The sustained-release agent is a mixture obtained by mixing carboresin, povidone, and micropowder silica gel in a weight ratio of 1:1:2.
[0074] Preparation method: under the condition of 5-15°C, gradually add the slow-release agent into glycerin, after fully swollen, add liquid chlorine dioxide and essence, stir evenly, place it at room temperature, and obtain it after fully hardening Slow-release solid chlorine dioxide.
Embodiment 2
[0075] Example 2: A slow-release solid chlorine dioxide preparation, the selected dosage form of which is block, made of the following raw materials (by mass percentage):
[0076] Liquid chlorine dioxide 25%; sustained release agent 45%; glycerin 28%; essence 2%. The sustained-release agent is a mixture of carbomer resin, povidone, and micropowder silica gel in a weight ratio of 1:1:1.
[0077] The preparation method is the same as in Example 1.
Embodiment 3
[0078] Embodiment 3: A slow-release solid chlorine dioxide preparation, the selected dosage form is block, made of the following raw materials (mass percentage):
[0079] Liquid chlorine dioxide 12%; sustained release agent 55%; glycerin 30%; essence 3%. The sustained-release agent is a mixture of carbomer resin, povidone, and micropowder silica gel in a weight ratio of 2:1.5:0.5.
[0080] The preparation method is the same as in Example 1.

Abstract
The invention provides a sustained-release solid chlorine dioxide preparation.The sustained-release solid chlorine dioxide preparation comprises, by weight, 0.5%-25% of one or a mixture of liquid chlorine dioxide and a chlorine dioxide water solution, 20%-70% of sustained-release agents, 5%-40% of hygroscopic agents and 0.1%-3% of essence.The sustained-release solid chlorine dioxide preparation is prepared according to the steps of gradually adding the sustained-release agents into the hygroscopic agents at 5-15 DEG C, adding the liquid chlorine dioxide after sufficient soluble inflation, uniformly stirring and placing in a room temperature environment for sufficient hardening.The sustained-release solid chlorine dioxide preparation which is prepared from the highly water-soluble materials is soluble to water easily and used for cleaning, soaking or being sprayed on objects needing disinfection quite conveniently.The sustained-release solid chlorine dioxide preparation is simple in technology, low in price, safe and effective to use, capable of releasing chlorine dioxide gas in a sustained manner and long in effective service life.
Description
technical field [0001] The invention belongs to the technical field of disinfectants, and relates to a slow-release solid chlorine dioxide preparation and a preparation and use method thereof. Background technique [0002] Chlorine dioxide is chemically active and not very stable. Generally, the purified chlorine dioxide gas is introduced into an inert solution composed of a stabilizer to make a colorless or light yellow clear, colorless, odorless, stable, non-volatile, and difficult-to-decompose stable chlorine dioxide aqueous solution. Add activator to activate when used. However, the effective release period of liquid chlorine dioxide after activation is short, and transportation, storage and use are all inconvenient. In order to further expand the use and scope of chlorine dioxide, a new chlorine dioxide product prepared by solidifying liquid chlorine dioxide on a carrier can effectively prolong the release time of chlorine dioxide. At present, the reason for restrict...
