Abstract

The invention discloses a preparation method for a high-temperature-resistance zinc titanate/silicon dioxide protection material and the protection material obtained through the method. The preparation method is characterized in that: the specific steps includes adding template polymers into solvent to obtain template polymer solution, mixing organic silicon or nanometer silicon dioxide, water and inorganic acid to obtain silicon source solution, uniformly mixing the template polymer solution and the silicon source solution to obtain spinning solution A, mixing titanium isopropoxy, zinc acetate and ethanol and adding template polymers to the mixture to obtain spinning solution B, performing electrostatic spinning for the spinning solution A and the spinning solution B to obtain a composite fiber membrane, and burning the composite fiber membrane to obtain the high-flexibility and high-temperature-resistance zinc titanate/silicon dioxide protection material. The protection material can serve as a protection material efficient-decomposition biochemical reagent under the high-temperature condition, and the decomposition ratio of paraoxon in simulation agent of the biochemical reagent is 80-95% in 10 minutes.

Description

technical field [0001] The invention relates to a preparation method of a highly flexible and high-temperature-resistant zinc titanate / silicon dioxide protective material, which belongs to the technical field of new materials. Background technique [0002] The existing protective materials for defense against poisonous smoke at home and abroad are mainly divided into three categories according to the protection objects: filled activated carbon for adsorbing organic toxic gases, activated carbon impregnated with chemical adsorbents, and nano-photocatalyst carbon fiber filter materials for purifying toxic gases. These three types of protective materials can play a certain role in defending against poisonous smoke under certain conditions. However, protective devices with activated carbon as the core filter layer are generally thick and heavy, which will bring a heavy physiological load to the wearer during use, and the adsorption capacity of this type of protective mat...
