Abstract

The invention discloses a textile of a rapid self-purification chemical warfare agent simulant and a preparation method of the textile. The preparation method comprises the following steps that a non-woven fabric is immersed into a mixed solution containing a polyphenol compound and 3-aminopropyl triethoxysilane to obtain a polyphenol hybrid coating modified non-woven fabric; and the non-woven fabric is dried and immersed into a solution containing zirconium tetrachloride and an organic ligand for hydrothermal reaction, so that a zirconium-based metal organic framework compound generated by the reaction is loaded on the surface of the polyphenol hybrid coating modified non-woven fabric, and the textile of the rapid self-purification chemical warfare agent stimulant is obtained. By means ofthe mode, the prepared textile can retain the excellent adsorption capacity and catalytic property of the zirconium-based metal organic framework compound, the degradation rate of the chemical warfare agent simulant is high, the half-life period is short, the conversion rate is high, and the textile can further be recycled after self-purification; and the preparation process is simple, the reaction conditions are mild, the used materials are economical and easy to obtain, the preparation method of the textile is suitable for industrial large-scale production, and a wide application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a fast self-purifying chemical warfare agent simulant textile and a preparation method thereof. Background technique [0002] Chemical warfare agents refer to various chemical substances that are used for war purposes, are highly toxic, and can poison or kill enemy humans, animals, and plants on a large scale. Whether they are released accidentally or intentionally, they will pose a serious threat to humans and the environment. At present, the defense against chemical warfare agents mainly utilizes the adsorptive properties of activated carbon-based filter media. However, these filter media often have problems such as secondary discharge after saturation and low long-term activation ability, and this type of filter media cannot degrade chemical warfare agents independently, and additional methods are still required to purify them. Therefore, it is necessary to develop a high-pe...
