Solid chlorine dioxide sustained-release material and preparation method thereof

Abstract

The invention discloses a solid chlorine dioxide sustained-release material and a preparation method thereof, raw materials comprise sodium chlorite, a solid acid, a carrier material, a coating agentand auxiliary agents; the carrier material is silicon dioxide aerogel micro powder; and the auxiliary agents include an accelerator, a stabilizer, and a binder. The solid chlorine dioxide sustained-release material can realize a controllable release rate of chlorine dioxide by silicon dioxide aerogel micro powder loading, polymer coating and accelerator adjustment, and has more excellent air purification effect; the safety, long-term stability and stability of the chlorine dioxide released by the solid chlorine dioxide sustained-release material can be realized by controlling of the mass transfer of a chemical reaction process for producing the chlorine dioxide; the solid chlorine dioxide sustained-release material product prepared by the method is convenient to use, can effectively removeair pollutants (such as formaldehyde), deodorizes (H2S), and sterilizes, air is purified, and the solid chlorine dioxide sustained-release material product is safe and environmentally-friendly, is stable and reliable in production process, high in efficiency and low in cost, and has a good market prospect.

Description

technical field [0001] The invention relates to the field of chlorine dioxide slow-release materials, in particular to a solid chlorine dioxide slow-release material and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, maintaining a suitable living environment has become particularly important. Indoor air quality is closely related to people's life and health. Chlorine dioxide is an internationally recognized safe, non-toxic and green disinfectant. Utilizing its strong oxidizing properties, harmful substances in the air such as formaldehyde, odor, bacteria and other substances can be converted into non-toxic products through chemical reactions, so chlorine dioxide has a good application prospect in the field of air purification. [0003] Chlorine dioxide was originally used for drinking water disinfection and food preservation, however, the use of chlorine dioxide in liquid environments limits its application fi...

Problems solved by technology

[0003] Chlorine dioxide was originally used for drinking water disinfection and food preservation, however, the use of chlorine dioxide in liquid environments limits its application fields

The use of chlorine dioxide gas has the following difficulties: ① high-concentration chlorine dioxide gas is dangerous, easy to explode, and can cause death by biological contact or inhalation; ② storage, transportation and use of gas are inconvenient

The disadvantage of this method is that the release rate of chlorine dioxide is greatly affected by environmental factors, and the controllability is poor.

The current chlorine dioxide slow-release materials often have defects such as uncontrollable reaction rate, poor stability, and poor air purification effect.
