Further, the sustained release agent is composed of at least one of polyethylene glycol, polyvinylpyrrolidone and sodium dihydrogen phosphate.

The preparation method of the chlorine dioxide gel provided by the invention comprises the following steps:

putting the solid powder of the chlorine dioxide gel in the technical scheme into a container;

and adding water into the container, wherein the effervescent agent in the solid powder of the chlorine dioxide gel generates a large amount of bubbles when meeting water, so that the solid powder of the chlorine dioxide gel and the water are uniformly stirred.

The effervescent agent is added into the formula of the chlorine dioxide gel, so that the product can be free from stirring, troubles can not be brought to users even if solid powder is used for storage and sale, and the long-term preservation effect of the chlorine dioxide product is ensured. The finished product of the chlorine dioxide gel formed by the invention has uniform air holes, the whole product is white, and a large amount of direct chlorine dioxide gas does not exist, because the formula of the chlorine dioxide gel does not directly contain the chlorine dioxide gas, the chlorine dioxide gas is slowly released by the interaction of all components after the gel is generated, the concentration of the chlorine dioxide generated by the chlorine dioxide precursor of the invention is about 1.2-2 times higher than that of the conventional formula, the release effect is achieved, and the chlorine dioxide gel has the characteristics of high purity and high safety.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Thus, a feature indicated in this specification will serve to explain one of the features of one embodiment of the invention, and does not imply that every embodiment of the invention must have the stated feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.

The principles of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

The stirring-free chlorine dioxide gel provided by the invention is stored in solid powder form, so that the problem that the chlorine dioxide gel is not long in gel state storage time can be solved.

The solid powder of the chlorine dioxide gel is prepared from the following components:

24-39 parts of chlorine dioxide precursor, 13-22 parts of gel, 7-16 parts of activator, 16-28 parts of stabilizer, 11-21 parts of cross-linking agent, 8-17 parts of effervescent agent and 9-21 parts of sustained-release agent.

The chlorine dioxide precursor is composed of at least one of sodium chlorite, potassium chlorite, barium chlorite and magnesium chlorite.

The gel agent is composed of at least one of agar, carrageenan, gellan gum or xanthan gum, and polyacrylate.

The effervescent agent is composed of at least one of EDTA disodium, sodium bicarbonate and sodium carbonate.

The activator is composed of at least one of boric acid, sodium dihydrogen phosphate, citric acid, tartaric acid, oxalic acid, and dihydrogen phosphate.

The stabilizer is composed of at least one of anhydrous calcium chloride, anhydrous magnesium chloride, anhydrous sodium sulfate and anhydrous magnesium sulfate.

The cross-linking agent is composed of at least one of acrylamide and acrylate.

The sustained release agent is composed of at least one of polyethylene glycol, polyvinylpyrrolidone and sodium dihydrogen phosphate.

When the chlorine dioxide gel needs to be prepared, the specific preparation method is that the solid powder of the chlorine dioxide gel is placed in a container, then water is added into the container, and the effervescent agent in the solid powder of the chlorine dioxide gel generates a large amount of bubbles when meeting water, so that the solid powder of the chlorine dioxide gel and the water can be fully and uniformly stirred, thereby saving trouble and having good stirring effect.

In one embodiment, the chlorine dioxide gel may be formed by mixing an alkaline solution containing chlorine dioxide, an acidic material powder, such as sodium hydroxide or calcium hydroxide solution containing chlorine dioxide, citric acid powder, and a water-absorbing gel with a liquid material.

In another embodiment, the chlorine dioxide gel can be a mixture of chlorite, solid acid and water-absorbing polymer gel, wherein the polymer gel is a mixture of carrageenin, carbomer, fish gelatin, polyethylene glycol, polyacrylic acid, carboxymethyl cellulose and other organic substances as carriers and loaded with sodium chlorite, solid acid and the like, and when the chlorine dioxide gel is used, water is added and stirred to form a slow-release product capable of releasing chlorine dioxide gas within 1-3 months.

In the invention, the effervescent agent, such as sodium bicarbonate, is added into the solid-state formula of the chlorine dioxide gel of the two embodiments to form an anhydrous dry mixture, so that a user can realize long-term preservation of a chlorine dioxide product when not in use, when the user needs to use the chlorine dioxide gel, only water needs to be added into the solid-state powder of the chlorine dioxide gel, and the reaction generated after the water is added comprises two aspects, namely the reaction of the chlorine dioxide gel product formed after the original gel formula meets the water, and on the other hand, the effervescent agent can generate a large amount of bubbles when meeting the water and continuously emits out of the water to perform a stirring reaction, for example, the sodium bicarbonate can generate a large amount of carbon dioxide bubbles when meeting the water, and the carbon dioxide gas is harmless to the human body. After the reaction of the effervescing agent is finished, the stirring effect in the gel generation process is also finished, stirring-free chlorine dioxide gel is realized, the use by users is convenient, and the gel product is uniform and good and has excellent quality.

Further, a transparent glass bottle can be used as a reaction container of the gel product, so that a user can observe the process of stirring by generating bubbles in water in the stirring-free process, product interest points are increased, and the product can be further promoted to be sold. The finished product of the chlorine dioxide gel has the characteristics of porosity, high concentration of chlorine dioxide, white color, no retention and decomposition of generated dichloride, low toxicity and the like.
